Hyperbrowser

Answer in brief

Credit-billed cloud Chrome sessions with profiles, stealth and captcha solving, plus one-shot agent runs (Claude Computer Use, OpenAI CUA, Browser Use) and separate VM-based code sandboxes. A credit-priced browser cloud with the broadest built-in agent-model support, held back by thin isolation and compliance documentation.

Overview

Hyperbrowser is a cloud platform for AI agents from the Y Combinator-backed company of the same name. Its browser product gives you Chrome sessions you drive with Playwright or Puppeteer over CDP from the Node.js or Python SDK, with live view, recordings, profiles, stealth and captcha solving. The docs describe sessions as isolated browser instances but do not name the boundary. An Agents API runs a task to completion with HyperAgent, Browser Use, Claude Computer Use or OpenAI CUA, either blocking or by polling a job.

Everything bills in credits (1,000 per dollar): browsers at $0.10 per hour, proxies at $10/GB and agent steps at $0.02. Per-session timeouts run from 1 to 720 minutes, and keepAlive holds a session across disconnects. A separate Sandboxes product (CPU, GPU and beta macOS) runs code in isolated virtual machines with volumes and custom Docker images, priced per vCPU-hour and GiB-hour; this record covers the browser product. An hyperbrowser-mcp server exposes scrape, extract and crawl tools.

Notable

Y Combinator company (YC profile lists Summer 2021 batch, founded 2021, team of 4, San Francisco)
Homepage claims 100M+ browser sessions run and 1,000+ concurrent isolated browsers
Five regions, with asia-south limited to Enterprise and Select plans

Hyperbrowser specifications

Attribute	Details
Isolation	Sessions are described as isolated browser instances running in the cloud; the boundary is not named. The separate Sandboxes product states commands run in isolated virtual machines
Deployment	Hosted platform
Open source	No
SDKs and interfaces	Python, JavaScript/TypeScript, CLI, REST API, MCP server
Cold start (vendor claim)	Homepage claims under 500 ms from request to a ready browser
Max session length	Team default timeout (configurable in settings); per-session timeoutMinutes from 1 to 720 (12 hours); keepAlive keeps a session running after CDP disconnect until timeout or stop
Persistence	Profiles snapshot the user data directory (cookies, local storage, session storage, cache) and reload it in later sessions; persistChanges controls writes; profiles.fork() copies a profile
GPU	No for browsers; GPU (CUDA) sandboxes exist in the separate Sandboxes product
Networking	Residential proxies at $10/GB with country/state/city selection or custom proxies; captcha solving; basic and ultra stealth modes
Pricing	Credits, 1,000 credits = $1. Browser $0.10/hour, proxy $10/GB, sandboxes $0.045/vCPU-hour + $0.015/GiB-hour, HyperAgent/Browser Use $0.02/step. Free: 5,000 credits, 1 concurrent. Startup $30/month: 30,000 credits, 25 concurrent. Scale $100/month: 100,000 credits, 100 concurrent. Enterprise: custom, 1,000+ concurrent
Free tier	Free plan: 5,000 credits (about 50 browser hours at base rate), 1 concurrent session, 7-day retention
Compliance	Security programme aligned with SOC 2 Trust Services Criteria with independent assessments; no certification named; production data stored in US cloud databases unless agreed otherwise
Regions	us-central, us-east, us-west, europe-west; asia-south on Enterprise/Select plans

Strengths and trade-offs

Strengths

You want low per-hour browser pricing with a usable free tier
You need to run Claude Computer Use, OpenAI CUA or Browser Use as a hosted task
You want profiles that persist logins and can be forked
You need a European or Asian region

Trade-offs

Isolation boundary for browsers is not documented
No named compliance certification; only alignment with SOC 2 criteria
No self-hosting or BYOC
The MCP server covers scraping and crawling rather than interactive browsing

Good fit for: Agents that need cheap browser hours with a built-in path to run computer-use models as one-shot tasks.
