Bright Data and Rayobyte are both EWDCI-certified, both offer residential and datacenter networks, and both target scraping workloads at scale. That shared foundation is where the comparison diverges sharply — one is built around residential infrastructure backed by contractual guarantees, the other around datacenter diversity and an access model that removes traffic expiry as a cost variable.

Bright Data's residential pool, provider-reported at 150M+ IPs, is backed by a published SLA, a Proxy Manager with HAR-level visibility, and ASN and carrier targeting that extends precision down to network-operator level. Rayobyte's competitive angle is different: a datacenter network spanning 300K+ IPs across 20,000+ C-class subnets and 9 ASNs with automatic 30-day IP replacements, a PAYG residential plan where traffic does not expire, and a Web Scraping API with free monthly usage included on signup.

Teams choosing between them are choosing between residential depth with operational guarantees and a datacenter-anchored multi-format network with accessible entry mechanics.

Bright Data suits teams with enterprise-grade residential requirements: carrier or ASN-level targeting, a contractual SLA with uptime and response commitments, HAR-level traffic debugging, dedicated residential IP assignment, or a pool in the hundreds of millions of IPs. The limitations are consistent with the enterprise tier: KYC gates full residential access, no non-expiring traffic option exists, and the product assumes organizational readiness to match its depth.

Rayobyte suits teams that need datacenter diversity — 20,000+ C-class subnets with automatic replacement cycles — alongside a residential PAYG option where purchased traffic does not expire. The Web Scraping API provides 5,000 free monthly scrapes on signup. Country, state, city, and ASN targeting are included at no extra cost on residential proxies. The limitations are real: no SLA is published, carrier targeting is not documented, the residential pool at 40M+ IPs is smaller, no HAR-level instrumentation exists, and sticky session TTL is not published.

Bright Data's philosophy is that residential proxy infrastructure at enterprise scale requires depth and contractual accountability. The SLA commits to 99.99% uptime and a 15-minute engineer response. ASN and carrier targeting allow routing by network operator. Dedicated residential IPs provide exclusive peer assignment. The Proxy Manager exposes HAR-level traffic for debugging and automatic failover. The product bets that teams with serious residential requirements will pay for the guarantees that make those requirements reliable.

Rayobyte's philosophy is that proxy access should not carry arbitrary expiry pressure or format limitations. PAYG residential traffic is non-expiring — teams pay for what they need without a clock forcing premature upgrades or waste. The datacenter network prioritizes subnet and ASN diversity: 300K+ IPs across 20,000+ C-class subnets, with automatic 30-day replacement cycles that maintain IP freshness without manual intervention. EWDCI membership validates the sourcing ethics without requiring enterprise onboarding friction.

You gain residential scale, carrier targeting, and contractual guarantees with Bright Data. You give up non-expiring traffic and datacenter subnet diversity. With Rayobyte, the trade runs in reverse — you gain non-expiring access and datacenter diversity, and the SLA, HAR instrumentation, and carrier targeting become unavailable.

Bright Data's residential pool is provider-reported at 150M+ unique IPs across 195 countries. Residential and mobile proxies support country, state, city, ZIP, ASN, and carrier targeting. Datacenter and ISP proxies support country and city only. The mobile pool covers 7M IPs. Dedicated residential IPs with exclusive peer assignment are available. Session TTL is fixed at 7 minutes and not configurable. Four proxy types are offered: residential rotating and dedicated, datacenter, mobile, and ISP static.

Rayobyte's residential pool is provider-reported at 40M+ IPs. Country, state, city, and ASN targeting are included at no extra cost on residential proxies — ZIP and carrier targeting are not documented. Sticky sessions are available; maximum duration is described as a 'longer period of time' without a specific TTL published. The datacenter network spans 300K+ IPs across 20,000+ C-class subnets and 9 ASNs in 27+ countries, with automatic 30-day IP replacements and instant individual replacements. ISP static proxies draw from 9+ ASNs with unlimited bandwidth at 1 Gbps; rotating ISP is also available as a separate product. Mobile proxies are not offered as a standalone product.

Bright Data authenticates via username and password in the proxy URL. Targeting parameters are passed as flags in the proxy username per request. The REST API covers zone management and configuration. The open-source Proxy Manager handles multi-zone orchestration with HAR logging and automatic failover. IP whitelist is not the primary authentication method. KYC is required before full residential access.

Rayobyte provides a proxy management API and a Web Scraping API with 5,000 free monthly scrapes included on signup. API rate limits and full endpoint documentation are not published on the product page. HTTP/S and SOCKS5 protocols are confirmed; UDP is not documented. A free residential trial is available via account creation without requiring sales contact. Custom billing applies to orders above 5,000 GB per month on residential or 5,000 IPs per month on ISP. Multiple payment methods are accepted including PayPal and Google Pay.

Bright Data bills residential and mobile proxies per GB, with PAYG and subscription tiers available. Free trial credits are provided for new accounts. No non-expiring traffic option is documented — purchased or subscription GB follow standard monthly billing cycles. KYC must be completed before billing can begin on the full residential network.

Rayobyte's PAYG residential plan uses non-expiring traffic — purchased GB do not expire, removing the pressure to use or lose bandwidth within a billing cycle. Subscription residential plans are also available. Datacenter proxies are billed per IP from a low entry point. ISP proxies are billed per IP with unlimited bandwidth. A free trial for residential proxies is available via account creation. Datacenter and ISP trials require contacting support.

Carrier targeting, a published SLA, HAR instrumentation, dedicated residential IPs, or a residential pool in the hundreds of millions are requirements. Bright Data fits.

Non-expiring PAYG residential traffic, datacenter subnet diversity with automatic IP replacement, or a Scraping API with free monthly usage are the priorities. Rayobyte fits.

You gain residential scale, carrier targeting, and contractual guarantees with Bright Data. You give up non-expiring traffic and datacenter diversity. With Rayobyte, the trade runs in reverse — you gain non-expiring access and datacenter diversity, and SLA coverage, HAR instrumentation, and carrier targeting become unavailable.

Neither fits teams that need mobile proxies with carrier-level targeting without committing to an enterprise-tier provider.

Ask whether your residential workload requires carrier-level routing precision, a contractual SLA with engineer response commitments, or HAR-level traffic debugging. If yes — Bright Data's operational depth addresses those requirements, and KYC onboarding is the cost of access.

Ask whether your team's cost model benefits from non-expiring traffic — no pressure to consume purchased GB within a billing window — or whether datacenter diversity across 20,000+ subnets with automatic replacement cycles is the operational priority. If yes — Rayobyte's access model and datacenter stack address those directly, and the absence of a contractual SLA and carrier targeting are the constraints to accept.

If your requirement is residential scale and contractual guarantees — Bright Data. If your requirement is non-expiring access and datacenter diversity — Rayobyte.
