# Spend Less on BrightData Bandwidth Drop-in egress optimizer for BrightData. Proxy Saver sits in front of your provider, reduces the data you send upstream, and delivers egress fingerprints out of the box. - **Up to 50% bandwidth reduction** via shared caching, in-flight deduplication, and content stubbing. - **Lower latency** via connection reuse, TLS session resumption, and DNS caching. - **Egress fingerprint out of the box.** JA3/JA4 coherence on all upstream traffic, real-browser impersonation on demand.

Scrapfly adds the egress optimization layer on top. ### Bandwidth Savings Every request routed through Proxy Saver passes through a deduplication and caching stack before touching BrightData. Identical in-flight requests are collapsed into a single upstream call; cached responses replay without hitting the wire. Content stubbing can replace images and stylesheets to shrink payloads further when the assets are not required for your workflow. **Dedupe** concurrent requests collapsed **Cache** zero upstream GB on hit **Stubbing** strip images & stylesheets **No-bill** failed attempts free [View billing docs →](https://scrapfly.io/docs/proxy-saver/billing) ### Latency Gain via Connection Reuse Proxy Saver keeps upstream connections alive and reuses TLS sessions across requests. Keep-alive pooling, HTTP/2 multiplexing, TLS ticket and session resumption, and DNS caching all combine to eliminate redundant handshakes and reduce tail latency. **Keep-alive** pooled conns **HTTP/2** multiplexing **TLS** session reuse DNS cache Smart retry Session sticky Fewer handshakes ### Egress Fingerprint Out of the Box Anti-bot stacks correlate TLS fingerprints against the proxy exit ASN. Proxy Saver overlays coherent JA3/JA4 and HTTP/2 SETTINGS frames on your BrightData egress so the client signature matches the proxy identity end to end. Passthrough mode preserves your original fingerprint. Impersonation mode replaces it with one of 16+ real-browser profiles. **JA3** TLS client print **JA4** next-gen print **HTTP/2** SETTINGS frame **16+** browser profiles [JA3 checker](https://scrapfly.io/web-scraping-tools/ja3-fingerprint) [HTTP/2 checker](https://scrapfly.io/web-scraping-tools/http2-fingerprint) [View fingerprint docs →](https://scrapfly.io/docs/proxy-saver/fingerprints) ### PAC-File Routing & Failover Per-domain rules and multi-provider failover without touching application code. Keep your BrightData credentials; add a fallback pool for domains that need it. **Per-domain**rules **Failover**automatic ### Usage Visibility Per-instance metrics (transited GB, balance) so you can verify the effect. Every request gets a `log_url` debug panel with headers, cookies, rendered HTML, and HAR waterfall. **log\_url**every request **GB**per instance **HAR**waterfall ### Zero Code Changes Replace your BrightData proxy credentials with a Proxy Saver instance from your Scrapfly dashboard. Same protocol (HTTP/HTTPS/SOCKS5), same client, under five minutes to connect. **HTTP**support **HTTPS**support **SOCKS5**support [Getting started guide →](https://scrapfly.io/docs/proxy-saver/getting-started) --- SETUP## Set Up in 5 Minutes Drop in, no code changes required. 1 **Point your client to the Proxy Saver endpoint.**Replace your BrightData proxy host/port with the Proxy Saver instance address from your dashboard. No other changes needed. 2 **Install the CA cert for HTTPS interception.** (Optional)Required only if you want caching and stubbing to apply to HTTPS traffic. One-time install, managed certificate rotation. 3 **Forward your BrightData options as-is.** (Optional)Country, session ID, and other BrightData-specific parameters pass through unchanged. --- COMPARISON## Direct to BrightData vs Proxy Saver in Front | Feature | Direct to BrightData | Proxy Saver + BrightData | |---|---|---| | **Bandwidth Use** | Full payload billed upstream | ✓ ~50% reduction of typical usage \* | | **Connection Reuse** | New connections more often; pooling depends on your client | ✓ Keep-alive pooling, HTTP/2 multiplexing, TLS session/ticket reuse, DNS cache | | **Content Stubbing** | Downloads all resources | ✓ Optional image/CSS stubbing to shrink responses | | **Egress Fingerprint** | Whatever your client/browser emits | ✓ Passthrough by default · real-browser impersonation (16+ profiles) on demand | | **Shared Caching** | Per-job / per-instance only | ✓ Shared cache across runs/sessions for repeatable targets | | **PAC-File Routing** | Manual routing if you build it | ✓ Per-domain rules, multi-provider failover, split routing | | **Protocol Support** | As supported by BrightData | ✓ HTTP/HTTPS/SOCKS5 ✓ curl, Requests, HTTPX ✓ Playwright, Puppeteer, Selenium | | **Cost per GB (Proxy Saver layer)** | — | ✓ $0.20 / GB standard · +$0.10 with fingerprint impersonation | *\* Actual reduction depends on your targets (asset density, cacheability, repeated URLs) and retry profile.* --- LEARN## Docs, Tools, and Setup Guides Everything you need to connect your BrightData account and start saving bandwidth. ### Proxy Saver Docs Getting started, billing, fingerprints, optimization guides.

No. Proxy Saver is a middleware service between you and BrightData. It reduces the bandwidth billed to your existing provider contract, not the contract itself. ### How does the egress fingerprint work? If you are using Proxy Saver with a real browser for the outgoing connection, it automatically uses the browser fingerprint. For other HTTP clients, use the `FpImpersonate` parameter to choose from over 16 [available fingerprint profiles](https://scrapfly.io/docs/proxy-saver/fingerprints#available-fingerprints). ### What libraries does Proxy Saver work with? Proxy Saver works with any library or programming language using standard proxy authentication. Instead of your BrightData credentials, create a [Proxy Saver instance](https://scrapfly.io/docs/proxy-saver/getting-started#usage) in your Scrapfly dashboard and use those credentials. ### Do I need to change my application code? No. Replace your BrightData proxy credentials with the Proxy Saver instance credentials from your Scrapfly dashboard. That is the only change required. ### How is Proxy Saver billed? Proxy Saver charges $0.20 per GB of traffic routed through the service. Fingerprint impersonation adds $0.10 per GB. This is billed on top of whatever BrightData charges you directly. --- // PRICING## Bandwidth-based billing, no per-request markup. Pay for data transferred, not for the number of requests. $0.20 / GB standard, +$0.10 / GB with egress fingerprint impersonation. **Free tier**1,000 free credits on signup. Enough to test all proxy modes with BrightData, no card required. **Pay on success**Only billed on successful proxy responses. Failed upstream attempts are free. **No lock-in**Upgrade, downgrade, or cancel anytime. No contract.
