Rayobyte and MarsProxies both offer non-expiring PAYG residential billing and both emphasize ISP proxies as part of their product stack — Rayobyte through ISP static proxies with unlimited bandwidth, MarsProxies through ISP proxies with 99.99% uptime and guaranteed failed IP replacement. The shared pricing model and ISP focus reveal a genuine operational divergence beneath the surface.

Rayobyte documents ASN targeting on residential proxies at no extra cost, operates a datacenter network across 20,000+ C-class subnets with automatic 30-day IP replacement cycles, and includes a Web Scraping API with 5,000 free monthly scrapes. MarsProxies offers sticky sessions configurable from 1 second to 7 days and backs its ISP product with a 99.99% uptime commitment and a guaranteed IP replacement policy.

Both serve mid-market scraping teams. The comparison turns on whether datacenter diversity and ASN residential targeting or session control precision and ISP reliability guarantees match the workload.

Rayobyte suits teams that need ASN targeting on residential proxies, automated datacenter IP freshness across 20,000+ C-class subnets, or a Scraping API with free monthly usage. Non-expiring PAYG available. The limitations: no ISO or SLA, pool at 40M+, mobile not a standalone product, sticky TTL not published.

MarsProxies suits teams that need sticky sessions from 1 second to 7 days, ISP proxies with 99.99% uptime and guaranteed failed IP replacement, and non-expiring PAYG — and whose residential workload fits within a 1M+ pool. The limitations: pool small for high-volume use, ASN targeting not documented, no compliance certifications, no free trial.

Rayobyte's philosophy is that proxy access should not depreciate and datacenter IP management should not require manual intervention. Non-expiring PAYG retains bandwidth value. The datacenter network refreshes automatically every 30 days across 20,000+ C-class subnets. ASN targeting at no extra cost extends residential routing precision. EWDCI certified membership validates ethical sourcing.

MarsProxies' philosophy is that session control precision and ISP reliability are underserved in the proxy market. 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 intervention. Non-expiring PAYG removes billing-cycle pressure. The 1M+ residential pool is honestly positioned.

You gain ASN residential targeting and automated datacenter maintenance with Rayobyte. You give up sub-second session granularity and ISP uptime guarantees. With MarsProxies, the trade runs in reverse — you gain session precision and ISP reliability commitments, and ASN residential targeting and automated datacenter replacement become unavailable.

Rayobyte's residential pool is provider-reported at 40M+ IPs. Country, state, city, and ASN targeting confirmed at no extra cost. ZIP and carrier targeting not documented. Sticky TTL not published specifically. Datacenter spans 300K+ IPs across 20,000+ C-class subnets and 9 ASNs in 27+ countries with automatic 30-day replacement. ISP proxies from 9+ ASNs with unlimited bandwidth at 1 Gbps. Mobile not offered as standalone product.

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 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 on flexible lease terms.

Rayobyte provides proxy management API and Web Scraping API with 5,000 free monthly scrapes. HTTP/S and SOCKS5 confirmed; UDP not documented. Free residential trial via account creation. Multiple payment methods including PayPal and Google Pay.

ASN targeting on residential proxies, automated datacenter IP replacement across 20,000+ subnets, or a Scraping API with free monthly usage are priorities. Both offer non-expiring PAYG. Rayobyte fits.

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

You gain ASN residential targeting and automated datacenter maintenance with Rayobyte. You give up session precision and ISP uptime guarantees. With MarsProxies, the trade runs in reverse — you gain session granularity and ISP reliability, and ASN targeting and automated datacenter replacement become unavailable.

Neither holds compliance certifications — teams with those requirements should look elsewhere in this set.

Ask whether ASN-level residential routing or automated datacenter IP freshness across 20,000+ subnets are the operational priority. If yes, and a large residential pool is needed, Rayobyte addresses those directly.

Ask whether your scraping workflow depends on controlling session duration to the second — or whether ISP proxies with a documented uptime commitment are the priority. If yes, and the 1M+ residential pool fits, MarsProxies' session granularity and ISP reliability are the fit.

If your requirement is ASN targeting and automated datacenter management — Rayobyte. If your requirement is session precision and ISP reliability — MarsProxies.
