Residential proxy network for web data access at scale
A large, dynamically rotating pool of ethically sourced residential addresses spanning 195+ countries and regions.
Pin requests to specific countries, cities or autonomous system numbers so results reflect the market you are studying.
A time-based subscription with no traffic ceiling and unrestricted concurrent connections for heavy, continuous scraping.
Dedicated, long-term IPs with unlimited traffic, priced per IP per day and available in 30+ countries.

Cloud browsers and web APIs for AI agents
Spin up scalable, sandboxed headless browsers on demand and drive them with Playwright, Puppeteer, Selenium, or the Stagehand framework.
Find relevant websites from a single query and convert any URL into clean HTML, JSON, or markdown built for LLM context.
Authenticate agents and get through login walls, CAPTCHAs, and anti-bot systems so workflows do not stall mid-task.
Inspect sessions with live view, replay, structured logs, and debugging across prompts, model calls, and browser actions.
Free / Open-sourceOpen-source alternative providing ready-made agent loops, but requires self-hosting or managing your own underlying browser infrastructure.

SpecialistAllows custom containerized browser deployments with extreme scalability, but requires manual setup rather than managed browser APIs.

Offers built-in agentic web automation and search features, but is less focused on raw low-level browser infrastructure control.
Provides reliable remote Chrome sessions for automation, but lacks the robust developer debugging toolkit built into Browserbase.


Excels at massive-scale web scraping and proxy management, but is less tailored for real-time interactive AI agent sessions.

SpecialistSpecializes in anti-detect browser profiles and persistent logins, but offers fewer developer-focused APIs for autonomous agent workflows.


Provides similar headless browser API access and scalability, but lacks Browserbase's specialized session debugging tools.
