MarsProxies Review

MarsProxies sells rotating residential proxies alongside dedicated ISP (static residential), datacenter and mobile proxies, all managed from one dashboard. Its pitch is aimed at individuals and small teams: residential traffic you can buy from 1 GB that never expires, and static or mobile IPs you can rent for as little as one day. It's a common pick for sneaker and retail bots, social media account work and small scraping jobs.

The trade-off is depth for flexibility. MarsProxies' stated residential pool (1M+ IPs) is a fraction of what the largest networks claim, targeting stops at city level, there's no free trial and the refund policy is narrow. In return you get straightforward per-GB and per-IP pricing, sticky sessions of up to 7 days and low entry prices for dedicated IPs. Whether that's a good deal depends on how much you buy and how regularly.

MarsProxies at a glance

MarsProxies proxy products

MarsProxies sells four proxy families. Residential traffic is billed per GB; the other three are billed per IP (or per proxy port) for a fixed period with unlimited bandwidth.

Residential proxies

Residential proxies are the product most people come to MarsProxies for. It claims over 1 million residential IPs in 190+ locations and says each IP comes from a real device with an ISP-issued connection. All traffic goes through one gateway, ultra.marsproxies.com on port 44443.

Targeting. You can target by region, country, US state and city. Country targeting accepts several countries at once (for example Spain, France and Italy), and the gateway picks one at random for each connection. There's no ZIP code, ASN or carrier targeting, which rules MarsProxies out for very local SEO checks or ISP-specific testing. MarsProxies says location targeting carries no extra cost.

Sessions. By default every request gets a new IP. For sticky sessions you add a session ID and a lifetime, which can be anywhere from 1 second to 7 days. Because residential exit devices can go offline at any time, MarsProxies warns that it can't guarantee you'll keep the same IP for the full session. Its documentation also describes a _forcerandom-1 option that widens the pool the gateway picks from on rotating connections.

Performance claims. MarsProxies quotes an average 98.4% success rate for residential proxies on its product page and in its documentation; its homepage comparison table rounds this to about 99%. We haven't verified either figure.

Limitations. Some targets are blocked until you pass ID verification (see the policies section), concurrent sessions are unlimited but the pool is small for heavy rotation in less common countries, and the 1M+ figure is the only pool size MarsProxies publishes — it doesn't give per-country counts on its residential pages.

Best for: small and medium scraping jobs, retail and sneaker sites, social media tasks and anything with irregular traffic, where non-expiring GB matter more than a huge pool.

ISP (static residential) proxies

MarsProxies' ISP proxies are dedicated static IPs registered to internet service providers but hosted on datacenter servers, so they combine a residential ASN with datacenter speed. Each IP is reserved for you for as long as the order is active, and if you extend the order you keep the same addresses.

Bandwidth and concurrent sessions are unlimited, and both HTTP(S) and SOCKS5 are supported; you switch protocol in the order's dashboard page. MarsProxies claims 99.99% uptime in one place on its ISP pricing page and 99.9% elsewhere on the same page. It says it will replace failed IPs.

Location coverage is where MarsProxies' own pages disagree most. The pricing overview lists 40+ locations, the homepage comparison table says 195+, and the ISP product and pricing pages repeat a generic "Over 1M IPs in 190+ locations" bullet that clearly describes the residential pool. Its sneaker page mentions dedicated IPs in 50+ locations. The ISP pricing FAQ adds that prices vary by country and that city and state-level targeting costs a small additional fee, while the homepage table lists ISP targeting as "country only". Check the location list in the dashboard before you buy.

Best for: sneaker and limited-release drops, long-lived social media and e-commerce accounts, ad verification and any task that needs the same residential-looking IP for days or weeks.

Datacenter proxies

Datacenter proxies are dedicated IPs with unlimited bandwidth, sold per IP. MarsProxies doesn't sell shared datacenter proxies or rotating datacenter pools. The pricing overview lists 60+ locations, the homepage table says 190+ countries and about 100K IPs, and an older MarsProxies setup guide says 30+ countries — another set of numbers that don't line up.

They support HTTP(S) and SOCKS5, and MarsProxies claims high speeds and 99.99% uptime. The homepage lists datacenter targeting as country only. Datacenter IPs are the cheapest way to get a dedicated address from MarsProxies, but they're also the easiest for websites to identify, so they suit lightly protected targets rather than sites with strong bot protection.

Best for: bulk tasks, SEO tools, monitoring and automation where speed and cost per IP matter more than stealth.

Mobile proxies

MarsProxies' mobile proxies are dedicated mobile proxy ports on 5G, 4G, 3G and LTE carrier networks with unlimited data. You pick a location per order; the pricing overview lists 15 locations, although the mobile product page says 190+ locations worldwide and the homepage 195+. MarsProxies doesn't name carriers on its public pages.

The IP behind your port can rotate. MarsProxies' product page describes automatic rotation every 10 minutes, and its mobile setup guide adds a manual Rotate IP button in the dashboard. That guide (from March 2024) says automatic rotation isn't available on the daily plan and is enabled through support, so confirm the current behaviour before you order a one-day proxy. The product page lists HTTPS and SOCKS5 support.

Best for: social media account management, app testing, mobile ad verification and targets that block residential IPs.

MarsProxies pricing

MarsProxies prices residential proxies per GB with no expiry, and ISP, datacenter and mobile proxies per IP (or port) for a chosen number of days. Discounts apply automatically for larger quantities and longer periods. All prices below were checked on MarsProxies' pricing pages on 4 November 2026 and exclude VAT, which is added at checkout where it applies.

Residential proxy pricing

Totals other than 5 GB are calculated from the per-GB rate; the checkout may differ by a cent. The $1.65/GB headline rate needs a 10 TB purchase. More realistic small-team volumes of 10 to 100 GB cost $3.99 to $2.99 per GB. The pricing page itself says "save up to 67%" in one place and "up to 54%" in another; 67% matches the 10 TB tier. Because the traffic never expires, buying a larger bundle up front carries less risk than it does with monthly plans elsewhere. MarsProxies' documentation also mentions monthly billing for residential, but the pricing page shows only one-off pay-as-you-go purchases.

ISP proxy pricing

30-day plans (dedicated, unlimited bandwidth):

1-day rentals cost $1.39 per IP for 1 to 50 IPs, $1.36 at 100 to 200 IPs and $1.35 at 500 to 1,000 IPs — the "from $1.35" figure MarsProxies advertises. 90-day plans take 10% off: $8.07 for one IP for 90 days (about $2.69 a month), falling to $5.65 per IP at 1,000 IPs (about $1.88 a month). Prices can vary by country, and city or state targeting adds a small fee.

Datacenter proxy pricing

30-day plans (dedicated, unlimited bandwidth):

1-day rentals cost $0.99 per IP at every quantity in the price selector. The page's own FAQ says 90 IPs for a day cost $0.92 per proxy, which doesn't match the table — expect $0.99 unless the dashboard shows otherwise. 90-day plans range from $5.37 for one IP (about $1.79 a month) to $3.22 per IP at 1,000 IPs (about $1.07 a month).

Mobile proxy pricing

The 30, 60 and 90-day prices include plan discounts of 5%, 10% and 15%. There's no quantity discount: 1 and 1,000 proxies cost the same per unit. In the price selector the 1-day option is only offered for a single proxy. The prices above are for the location preselected on the pricing page; other locations may be priced differently in the dashboard.

Billing rules, trial and refunds

• No free trial. MarsProxies' pricing and product pages all say it doesn't offer one, and suggest buying the smallest plan to test instead.
• Non-expiring residential traffic. Purchased GB roll over indefinitely until used. There's no subscription to cancel.
• Fixed-period rentals. ISP, datacenter and mobile orders run for the period you pay for. You can extend an order manually or turn on auto-extend, which renews from your account balance three days before expiry and keeps the same IPs.
• Refunds. The Terms of Service (clause 6.9) say fees are non-refundable. The exception (6.9.1) is a service that's inactive or defective in the first 24 hours for reasons outside your control, which MarsProxies can't fix within that window — then you get a full refund if you report it promptly. If you report a problem after 24 hours, the service is presumed to have been fine. Crypto payments are never refundable (6.9.2), and MarsProxies' residential guide states that residential traffic isn't refunded.
• Payment. Cards, PayPal, Alipay, Google Pay and more than 12 cryptocurrencies (via CoinGate), though the exact list differs slightly between pricing pages. Older setup guides say crypto can only be used to top up your account balance, not at checkout.
• Taxes. VAT is excluded from listed prices and added at checkout where it applies.

What 10 GB, 100 GB and 1 TB actually cost

Because the traffic doesn't expire, there's no penalty for buying 100 GB if you only use 30 GB this month. At 10 GB, though, $3.99/GB is above what several budget providers charge, and MarsProxies only becomes competitive on price per GB from a few hundred GB upward. For static IPs, ten dedicated ISP IPs cost $27.81 for 30 days, and ten datacenter IPs cost $16.92.

Features and dashboard

MarsProxies' dashboard is simple and built around orders. From one account you can:

• Generate residential proxy lists. Pick one or more countries, a state or city, rotating or sticky sessions and their duration, HTTP(S) or SOCKS5, a DNS or numeric IP hostname, the number of sessions and the output format, then copy or download the list as a .txt file.
• Choose authentication. Residential proxies support username and password or IP whitelisting. MarsProxies' older datacenter guide says datacenter proxies only support username and password; check the dashboard for your product.
• Manage static and mobile orders. Each order page shows its IPs in IP:port:username:password format, lets you switch protocol, reset credentials and turn auto-extend on or off. Mobile orders add a manual Rotate IP button.
• Use the API. After you buy at least 1 GB of residential traffic, you can create an API token under Settings. The REST API (api.marsproxies.com) covers residential account balance, sub-users (create, update, delete, give or take traffic), orders (price calculation, create, list) and proxy generation, including lists of available countries and regions.
• Create sub-users. Sub-users get their own credentials and a traffic allocation drawn from your balance. The documentation pitches this for "reseller workflows", but the Terms of Service (clause 4.9) and Acceptable Use Policy prohibit reselling or redistributing the service, so get written confirmation before you build a resale business on it.

MarsProxies also lists free tools: Chrome and Firefox proxy extensions, Android and Apple proxy apps, an IP lookup tool and a proxy checker. Its integrations page covers dozens of antidetect browsers and tools, including AdsPower, GoLogin, Dolphin, Octo, MoreLogin, Undetectable and SwitchyOmega. MarsProxies doesn't sell a scraping API or unblocker, so you'll need your own scraping stack.

Setting up MarsProxies

For residential proxies, MarsProxies' documentation uses the HOST:PORT:USERNAME:PASSWORD format. Unlike most providers, it puts the targeting and session options in the password field, each added with an underscore:

Host:      ultra.marsproxies.com
Port:      44443
Username:  USERNAME
Password:  PASSWORD

Rotating:  ultra.marsproxies.com:44443:USERNAME:PASSWORD
Country:   ultra.marsproxies.com:44443:USERNAME:PASSWORD_country-us
US state:  ultra.marsproxies.com:44443:USERNAME:PASSWORD_country-us_state-texas
City:      ultra.marsproxies.com:44443:USERNAME:PASSWORD_country-de_city-berlin
Several:   ultra.marsproxies.com:44443:USERNAME:PASSWORD_country-es,fr,it
Sticky:    ultra.marsproxies.com:44443:USERNAME:PASSWORD_country-br_session-fsiwjtqc_lifetime-10m

The documented parameters are:

• _region- — a broad region, for example _region-europe.
• _country- — a two-letter ISO 3166-1 country code; separate several codes with commas and the gateway picks one at random.
• _city- — a city name, always used together with _country- because many city names exist in more than one country.
• _state- — a full US state name, used with _country-us.
• _session- — makes the session sticky; the value must be a random alphanumeric string of exactly 8 characters.
• _lifetime- — how long the sticky session lasts, from 1 second to 7 days, with a single time unit per value (the docs' example is 10m).
• _forcerandom-1 — for rotating connections, widens the pool the gateway selects from.

Here's a sticky US request with curl, using a public IP-echo service to check the exit IP:

curl -x "http://ultra.marsproxies.com:44443" \
  -U "USERNAME:PASSWORD_country-us_state-texas_session-ab12cd34_lifetime-30m" \
  "https://api.ipify.org?format=json"

The same in Python with requests:

import requests

username = "USERNAME"
password = "PASSWORD_country-de_city-berlin"
proxy = f"http://{username}:{password}@ultra.marsproxies.com:44443"

r = requests.get("https://api.ipify.org?format=json", proxies={"http": proxy, "https": proxy})
print(r.text)

SOCKS5 uses a different port from HTTP; the dashboard's proxy generator gives you the right one when you choose SOCKS5. ISP, datacenter and mobile proxies don't use the gateway: once an order is confirmed, the order page lists each proxy as IP:port:username:password, ready to paste into your bot, browser profile or script. MarsProxies says mobile proxies are usually ready within an hour of the order being confirmed.

IP sourcing, compliance and policies

Sourcing. MarsProxies says it builds its residential network "only from partner devices selected on a strictly explicit and consensual basis", and that every residential IP comes from a real device and a legitimate ISP. It also says it doesn't rent its residential IPs to others. Like most providers, it doesn't name the apps or SDKs its partners use or explain how peers are paid, so you can't check its consent model independently. For mobile proxies it says IPs come from real carrier networks, without naming carriers.

Certifications. MarsProxies' pages don't list any security or industry certifications, such as ISO/IEC 27001, SOC 2 or EWDCI membership. Buyers whose procurement process needs those will have to look elsewhere or ask sales directly.

KYC. MarsProxies doesn't require ID to sign up or buy, but its terms let it request identity verification at any time, and its Acceptable Use Policy says verification is needed to unlock blocked categories: .gov sites, bank sites, IMAP and mail ports (mail ports only after a spam check). According to its privacy policy, verification is handled by the third-party provider iDenfy using an ID document and a facial image, and MarsProxies receives only the result. MarsProxies also links to a spreadsheet of blocked websites from its ISP setup guide.

Acceptable use. The Acceptable Use Policy, last updated on 30 August 2026, bans malware, DDoS attacks, fraud (including click fraud and fake traffic), fake social media profiles, reviews and engagement, intellectual-property infringement and privacy invasion. It also forbids circumventing access controls, rate limits, robots.txt directives and API restrictions, accessing login- or paywall-protected content without authorisation, and making excessive requests to third-party sites. That's stricter wording than many proxy providers use, and it's worth reading if you plan to scrape at scale or manage accounts in bulk. Accounts can be suspended at MarsProxies' discretion, and terminated accounts don't get refunds.

Privacy. The privacy policy says MarsProxies collects account, device and dashboard-usage data, but does not collect or store proxy traffic and doesn't build browsing histories of the sites you visit through its proxies. Log and technical data are kept "for a limited period" without a stated number of days.

Transparency gaps. The biggest problem is inconsistency between MarsProxies' own pages: location counts for ISP, datacenter and mobile proxies range from 15 or 40+ to 190+; targeting for static proxies is "country only" on the homepage but "city-level" on the pricing pages; the datacenter one-day price is $0.99 in the selector but $0.92 in the FAQ; uptime is 99.9% or 99.99%; and older setup guides (from 2023 and 2024) still quote residential prices of $3.50 to $5/GB, a 24-hour sticky limit and a 10-IP datacenter minimum. None of this suggests bad faith, but you should trust the price selector and dashboard over marketing copy.

Customer support and documentation

MarsProxies offers 24/7 support through live chat on its website and dashboard (Intercom), by email, and through its Discord community, where it also handles some support tickets. Sales enquiries go through a contact form or the sales email. Customer reviews on MarsProxies' own site frequently mention support staff by name, but we haven't measured response times ourselves.

Documentation is split across three places. The developer docs (docs.marsproxies.com) are new and concise: they cover the residential proxy string, location and rotation parameters, protocols, sub-users and the full REST API reference with request and response schemas. The help center (help.marsproxies.com) has troubleshooting articles, including a guide to proxy error codes. Product setup guides for each proxy type live on the MarsProxies blog, along with integration tutorials for antidetect browsers and bots; several of those guides date from 2023 and 2024 and contain outdated prices and limits. A public status page (status.marsproxies.com) shows network health.

The documentation doesn't cover ISP, datacenter or mobile proxies in the same detail as residential, and there are no official code samples beyond the proxy-string examples. Developers used to the deeper docs of larger providers will find it thin, but for pasting credentials into a bot or browser it's enough.

Pros and cons

Who should (and shouldn't) use MarsProxies

MarsProxies is a good fit if you are:

• A sneaker or retail-bot user who needs a handful of dedicated ISP IPs for a drop and wants to rent them for a day or a month rather than sign up for a large plan.
• Someone with irregular residential usage. If you use 5 GB one month and 40 GB the next, non-expiring traffic means nothing goes to waste.
• A social media or e-commerce account manager who needs stable dedicated IPs (ISP) or a dedicated mobile port with unlimited data.
• A small scraping project on mainstream sites that needs country, state or city targeting and occasionally long sticky sessions.
• Budget-conscious buyers of static IPs who want 30-day dedicated ISP or datacenter IPs at a low price per IP.

Look elsewhere if you are:

• Scraping heavily protected sites at scale. A 1M+ residential pool is small, and you'll get more IP diversity from providers with tens of millions of IPs.
• Needing granular targeting such as ZIP code, ASN or mobile carrier.
• Wanting to test before paying. There's no free trial, and refunds are limited to faulty services in the first 24 hours.
• An enterprise buyer that needs SOC 2 or ISO 27001 documentation, invoicing on contract terms or a large account team.
• Planning to resell proxies. The terms prohibit resale, despite the sub-user feature.

MarsProxies vs alternatives

IPRoyal is MarsProxies' closest match in model: residential traffic that never expires, sticky sessions of up to 7 days, and ISP and datacenter proxies you can rent for short periods. It claims a much larger residential pool, which makes it the more natural choice if you want the same flexibility with more IP diversity, while MarsProxies has the lower headline residential rate and one-day mobile rentals. Compare it in our proxy provider directory.

DataImpulse also sells non-expiring residential traffic, but at a much lower price per GB and with a far larger stated pool, plus ZIP and ASN targeting. It's the better pick for budget residential scraping. It doesn't sell dedicated ISP IPs, though, so MarsProxies wins for sneaker and account work that needs static addresses. Read our DataImpulse proxies review.

Decodo costs more per GB at small volumes and uses monthly plans where unused traffic doesn't roll over, but it offers a free trial, a 14-day refund window, deeper targeting (ZIP and ASN), a much larger residential pool and ISO/IEC 27001 certification. Choose Decodo if you want lower risk and enterprise-grade paperwork; choose MarsProxies if non-expiring traffic and daily rentals matter more. Read our Decodo proxies review.

Final verdict

MarsProxies is a small, flexible proxy provider that does a few things well. Residential traffic that never expires, sticky sessions of up to 7 days and dedicated ISP, datacenter and mobile IPs you can rent for a single day make it easy to buy exactly what you need, when you need it. Its prices for 30-day dedicated ISP and datacenter IPs are low, and the new API and sub-users help if you manage several projects.

The weaknesses are just as clear: a small stated residential pool, city-level targeting at best, no free trial, a refund policy that only covers first-day faults, no published certifications and a website whose numbers often contradict each other. For sneaker drops, account management and modest scraping with irregular volume, MarsProxies is worth a small test order. For large-scale scraping of protected sites or enterprise procurement, compare it with the alternatives above first.
