Source: https://agentreadycrawlers.com/vendors/hyperbrowser Site: Agent Ready Crawlers Last reviewed: 2026-11-05 Crawler operator # Hyperbrowser In short Hyperbrowser lets a team restrict signing to as many as 50 hostnames, and keeps the signing identity fixed at www.hyperbrowser.ai. Its Web API endpoints for fetch, search and extract cannot sign at all, and the free account's 5,000 credits come before a USD 30 Startup plan. Type [Crawler operator](https://agentreadycrawlers.com/vendors/by-type/crawler-operator/) Homepage [hyperbrowser.ai](https://www.hyperbrowser.ai) In one line Cloud browser platform for AI agents whose sessions can sign requests with Web Bot Auth under the fixed Signature-Agent www.hyperbrowser.ai, on request per team, alongside stealth, proxies and CAPTCHA solving. Last read 2026-11-05 ## What Hyperbrowser does for this layer ### From the vendor's own pages Hyperbrowser sessions can sign their requests with Web Bot Auth following the IETF httpsig protocol draft, and the feature is enabled for teams on request. ([hyperbrowser.ai](https://www.hyperbrowser.ai/docs/sessions/web-bot-auth.md)) Hyperbrowser's Signature-Agent is always "https://www.hyperbrowser.ai", and its key directory is a JSON Web Key Set of Ed25519 keys whose kid is the RFC 7638 thumbprint, with every key also signing the directory response. ([hyperbrowser.ai](https://www.hyperbrowser.ai/docs/sessions/web-bot-auth.md)) Hyperbrowser tells site owners that signed requests come from real browsers and usually carry a standard browser User-Agent, so they should identify them by signature rather than by User-Agent. ([hyperbrowser.ai](https://www.hyperbrowser.ai/docs/sessions/web-bot-auth.md)) A Hyperbrowser session that asks for Web Bot Auth is either signed or refused and never starts unsigned; the option cannot be combined with useUltraStealth, and scrape, crawl and extract requests do not accept it. ([hyperbrowser.ai](https://www.hyperbrowser.ai/docs/sessions/web-bot-auth.md)) Hyperbrowser customers can limit signing to up to 50 hostnames, subdomains included, with the onlyDomains option. ([hyperbrowser.ai](https://www.hyperbrowser.ai/docs/sessions/web-bot-auth.md)) Hyperbrowser's pricing page gives a free account 5,000 credits, prices Startup at USD 30 a month and Scale at USD 100 a month, and bills browsers at USD 0.10 an hour and proxy data at USD 10 per GB, where 1,000 credits equal USD 1. ([hyperbrowser.ai](https://www.hyperbrowser.ai/pricing)) Hyperbrowser charges 9 extra credits per page for a fetch with ultra stealth or a chosen location, on top of 1 credit per fetched page. ([hyperbrowser.ai](https://www.hyperbrowser.ai/pricing)) Hyperbrowser's docs index lists Stealth Mode anti-detection settings and CAPTCHA solving, and an x402 endpoint that sells one browser session at 0.10 USDC per hour with no account or API key. ([hyperbrowser.ai](https://www.hyperbrowser.ai/docs/llms.txt)) ### What our crawl saw Hyperbrowser's key directory at www.hyperbrowser.ai/.well-known/http-message-signatures-directory returned HTTP 200, content type application/http-message-signatures-directory+json, with one Ed25519 key on 2026-11-05. ([hyperbrowser.ai](https://www.hyperbrowser.ai/.well-known/http-message-signatures-directory)) ## Products and plans | Product | What it does | Price model | From | As of | | --- | --- | --- | --- | --- | | Hyperbrowser sessions | Cloud browsers for agents with stealth, proxies, CAPTCHA solving and optional Web Bot Auth signing. | credits Startup a month; free account 5,000 credits; browser USD 0.10 an hour. | USD 30 | 2026-11-05 | | Hyperbrowser Web API (fetch, search, extract) | Page fetch and search endpoints; these cannot sign with Web Bot Auth. | No price recorded | ## Standards | Standard | Status | Evidence | | --- | --- | --- | | RFC 9309 (robots.txt) | No statement | The docs carry only a troubleshooting tip to check robots.txt; no crawl policy (2026-11-05). | | Web Bot Auth | Supports | Per-team opt-in signing with a fixed Signature-Agent and published key directory.
