Soax and MarsProxies both operate at mid-market pricing without enterprise compliance certifications. The pool gap is large — Soax at 155M+ residential IPs versus MarsProxies at 1M+ — but pool size is not the primary differentiator either provider has built around.

Soax built around operational visibility and mobile scale: real-time failure rate and banned IP dashboards, UDP and QUIC protocol support, and a mobile pool at 33M IPs from real cellular carriers. MarsProxies built around session control precision and ISP reliability: sticky sessions from 1 second to 7 days, ISP proxies with 99.99% uptime and guaranteed failed IP replacement, and non-expiring PAYG residential traffic.

For high-volume residential workloads, Soax's pool scale applies. For workloads requiring precise session timing or ISP reliability guarantees, MarsProxies' operational profile is the comparison axis.

Soax suits teams that need real-time failure rate and banned IP monitoring, UDP or QUIC protocol support, a 33M+ mobile pool from real cellular carriers, or a residential pool large enough for high-volume scraping. The limitations: certifications in progress but not yet obtained, ASN targeting not documented, Texas excluded, subscription billing required.

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: residential pool small for high-volume use, ASN targeting not documented, no compliance certifications.

Soax's philosophy is that proxy network value includes operational visibility. Real-time diagnostics let teams react to detection events before they compound. UDP and QUIC extend the protocol stack to non-standard workloads. The mobile pool at 33M IPs from real cellular carriers addresses volume-intensive mobile scraping at scale.

MarsProxies' philosophy is that session control precision and ISP reliability are the variables proxy teams most need but least often get. Sticky sessions from 1 second to 7 days cover the full timing spectrum. ISP proxies with 99.99% uptime and guaranteed replacement deliver predictable availability without manual pool management. Non-expiring PAYG removes billing-cycle pressure.

You gain operational observability, mobile scale, and a large residential pool with Soax. You give up sub-minute session control and ISP reliability guarantees. With MarsProxies, the trade runs in reverse — you gain session precision and ISP reliability commitments, and the observability dashboard, UDP/QUIC, and mobile pool scale become unavailable.

Soax's residential pool is provider-reported at 155M+ IPs across 195+ countries. Targeting covers country, region, city, and ISP. ASN and ZIP not documented. Texas excluded. Mobile pool 33M IPs from real cellular carriers across 3G/4G/5G/LTE. Protocol: HTTP/S, SOCKS5, UDP, QUIC. Session TTL not published. Dedicated residential IPs not offered.

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 set. Mobile proxies 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 dedicated only with failed IP replacement. Mobile dedicated IPs with unlimited bandwidth on flexible lease terms.

Soax provides API access with multi-language support. Dashboard exposes real-time diagnostics: failure rates, banned IPs, speed metrics, custom reports, and alerts. IP whitelist authentication not documented. Sub-user management not confirmed. Monthly subscription required.

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.

Soax offers four monthly subscription tiers with per-GB billing. Low-cost 3-day trial for nominal fee. No PAYG documented. No free tier.

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 flexible lease terms.

Real-time failure rate and banned IP dashboards, UDP or QUIC support, a 33M+ mobile pool, or a residential pool large enough for high-volume scraping are priorities. Soax fits.

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

You gain operational observability, mobile scale, and residential pool depth with Soax. You give up session precision and ISP reliability guarantees. With MarsProxies, the trade runs in reverse — you gain session granularity and ISP reliability, and the observability dashboard, UDP/QUIC, and mobile pool scale become unavailable.

Neither fits teams that require Texas-based residential IP availability.

Ask whether your operations team needs real-time visibility into failure rates and banned IPs — or whether your workload generates enough requests that a 1M+ residential pool creates IP repetition problems. If yes to either, Soax's observability layer and pool scale address 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 observability and mobile scale — Soax. If your requirement is session precision and ISP reliability — MarsProxies.
