Rebrowser

Cloud browser platform specializing in undetectable automation – patches Chromium to evade bot detection at the browser level.

Each tool is evaluated against our methodology using public docs, vendor demos, and hands-on testing.

Cloud browser infrastructure provides managed Chromium instances that AI agents can control remotely. These platforms handle the complexity of browser lifecycle management, anti-detection, session persistence, and scaling. They are used by AI agents that need to interact with authenticated websites, fill forms, or navigate complex multi-step web workflows.

Editorial assessment

Takes anti-detection to the browser engine level rather than just header spoofing. Chromium patches make automation genuinely harder to detect than standard Playwright or Puppeteer setups. Niche tool for a specific problem – if target sites don't use advanced bot detection, you're paying for capabilities you don't need. The anti-detect focus also raises ethical questions.

How Rebrowser compares

Steel.dev

Steel.dev offers stealth capabilities in a broader AI-agent platform rather than a standalone anti-detect browser.

Nstbrowser

Nstbrowser provides similar anti-detect features with fingerprint management and multi-account support.

Browserbase

Browserbase is the mainstream choice when you don't need deep anti-detection capabilities.

Frequently asked questions

How much does Rebrowser cost?

Rebrowser is a paid cloud browser platform. There is no free self-hosted option, since the service runs only on Rebrowser infrastructure. Pricing is tiered by plan, and on most cloud browser services you also pay for usage such as browser hours and data traffic on top of the base plan. Check the Rebrowser pricing page for current tier names and rates, as published numbers change and depend on your session volume.

Is Rebrowser open source?

No. The hosted anti-detect browser platform is a closed commercial product and cannot be self-hosted. Rebrowser does publish some open tooling separately, including patched browser automation forks and bot-detection test code, which you can run on your own. That tooling is distinct from the managed service you pay for, which runs only on Rebrowser servers.

What makes Rebrowser different from running plain Playwright or Puppeteer?

Rebrowser patches Chromium at the engine level to remove signals that bot-detection systems use to flag automation, such as Chrome DevTools Protocol leaks. Standard Playwright or Puppeteer setups expose those signals, so sites with advanced detection block them more easily. Rebrowser runs real browser sessions in the cloud and renders JavaScript like a full browser. The tradeoff is added cost for a narrow use case.

When should I choose Rebrowser over Browserbase?

Choose Rebrowser when your target sites use aggressive bot detection and your automation keeps getting blocked despite stealth plugins, since its value is engine-level evasion. Browserbase is a more general cloud browser for agents and automation without that anti-detect specialization. If your targets do not run advanced detection, Browserbase or a plain headless setup usually does the job for less money.

Who is Rebrowser best for?

It suits teams whose automation hits hard anti-bot walls on specific high-value targets and who have already tried lighter options. If the sites you scrape do not deploy advanced detection, you are paying for evasion you do not need, and a general cloud browser like Steel.dev or Nstbrowser fits better. The anti-detect focus also raises ethical and terms-of-service questions worth weighing first.
