NetNut and MarsProxies share an interesting overlap: both emphasize ISP proxies as a product differentiator. The similarity ends there. NetNut's ISP static pool is provider-reported at 1M+ IPs in 50+ countries, sourced through B2B agreements with ISPs via DiviNetworks. MarsProxies' ISP proxies are offered in 30+ countries with 99.99% uptime documented and guaranteed failed IP replacement.

NetNut's residential pool is larger at 85M+ IPs, but city targeting and API access require the highest subscription tier. MarsProxies' residential pool is 1M+ — unsuitable for high-volume workloads — but offers sticky sessions configurable from 1 second to 7 days and non-expiring PAYG without subscription commitment.

Teams choosing between them are choosing between ISP pool scale with plan-gated features, or ISP reliability guarantees with session precision and a small residential pool.

NetNut suits teams whose residential workload needs a pool larger than 1M+ IPs, or whose persistent-session use case requires a large ISP static pool. The limitations: city targeting and API access require Master tier, no PAYG, and the minimum commitment is high.

MarsProxies suits teams that need sticky sessions configurable from 1 second to 7 days, ISP proxies with 99.99% uptime and guaranteed failed IP replacement, and non-expiring PAYG without commitment — and whose residential workload fits within a 1M+ pool. The limitations: the residential pool is small, ASN targeting not documented, and no compliance certifications exist.

NetNut's philosophy is residential consistency through ISP-level sourcing at scale. The 1M+ ISP static pool enables persistent sessions across 50+ countries without consumer device dependency. The 85M+ rotating residential pool provides volume for high-throughput workloads. City targeting and API access are available — at the highest tier.

MarsProxies' philosophy is precision and reliability over scale. Session duration from 1 second to 7 days covers the full timing spectrum. ISP proxies with 99.99% uptime and guaranteed replacement deliver predictable availability without manual pool maintenance. Non-expiring PAYG residential traffic removes billing-cycle pressure. The residential pool at 1M+ is honestly positioned — the provider does not claim scale it has not built.

You gain residential pool scale and a large ISP static pool with NetNut. You give up session precision and ISP uptime guarantees. With MarsProxies, the trade runs in reverse — you gain session granularity and ISP reliability commitments, and residential scale and ISP pool scale become unavailable.

NetNut's rotating residential pool is provider-reported at 85M+ IPs across 200+ countries, ISP-direct and P2P hybrid. Country targeting on all plans. City and state require Master tier. ASN and ZIP not documented. ISP static pool 1M+ IPs in 50+ countries. Mobile 5M IPs in 100+ countries. Sticky session TTL not documented.

MarsProxies' residential pool is provider-reported at 1M+ IPs across 195 countries. Country, state, and city targeting confirmed. ASN targeting not documented. Sticky sessions configurable from 1 second to 7 days — finest granularity in this comparison set. Mobile proxies are rotation-only; sticky not available on mobile. ISP proxies in 30+ countries with 99.99% uptime and guaranteed failed IP replacement — dedicated, non-shared. Datacenter proxies dedicated only with failed IP replacement. Mobile dedicated IPs with unlimited bandwidth on flexible lease terms.

NetNut authenticates via username and password. IP allow-listing on Production and above. API access plan-gated to Master tier. Sub-user management on Production and above. Overages require account manager contact.

MarsProxies supports username and password and IP whitelist authentication. Session duration from 1 second to 7 days configured directly without support contact. HTTP/S and SOCKS5 confirmed; UDP not documented. 24/7 support via live chat, email, and Discord. No published response time SLA. Sub-user management not documented.

NetNut requires monthly subscription with no PAYG. High entry minimum. City targeting, API, and support features gated to higher tiers. 7-day free trial for registered companies requires KYC.

MarsProxies bills residential per GB on non-expiring PAYG with bulk discounts. No monthly commitment. No free trial — minimum 1 GB purchase. Crypto payments accepted. ISP and datacenter billed per IP. Mobile billed per device on daily or monthly lease terms.

A residential pool larger than 1M+ IPs, ISP pool at scale, or city targeting and API access are requirements — and the budget supports the Master tier. NetNut fits.

Sticky sessions from 1 second to 7 days, ISP proxies with 99.99% uptime and replacement guarantee, and non-expiring PAYG are the priorities — and the residential workload fits within 1M+ IPs. MarsProxies fits.

You gain residential pool scale and a large ISP static pool with NetNut. You give up session precision and ISP uptime guarantees. With MarsProxies, the trade runs in reverse — you gain session granularity and ISP reliability commitments, and residential scale and ISP pool scale become unavailable.

Neither fits teams that need both large residential pool depth and sub-minute session control granularity.

Ask whether your workload generates enough requests that a 1M+ residential pool creates IP repetition problems — or whether a large ISP static pool for persistent sessions across 50+ countries is the operational requirement. If yes, and your budget supports the Master tier, NetNut addresses those needs.

Ask whether your scraping workflow depends on controlling session duration to the second — or whether ISP proxies with a documented uptime commitment and automatic replacement are the priority. If yes, and the residential pool size fits your workload, MarsProxies' session granularity and ISP reliability address those directly.

If your requirement is residential scale and a large ISP pool — NetNut. If your requirement is session precision and ISP reliability guarantees — MarsProxies.
