CloakBrowser vs Stagehand
Which should you use? A side-by-side look at what each one does, who it suits, what it costs, how hard it is to set up, and where each falls short.
Open source · MIT
A Chromium browser modified for stealth, meant to be a drop-in swap for Playwright.
Open source · MIT
TypeScript, Python and Go SDK for letting AI control a web browser to act on and extract data from sites.
The short answer
Choose CloakBrowser if you need…
- Python or JavaScript developers already using Playwright who need automation to get past bot checks
- Scraping projects blocked by Cloudflare Turnstile or similar anti-bot systems, paired with a residential proxy
- Teams building AI agents that drive a real browser and hit bot detection
Choose Stagehand if you need…
- Developers building browser agents that must work on sites they do not control
- Teams extracting structured data from web pages that lack an API
- Engineers who already know Playwright and want AI-assisted steps
- Projects needing TypeScript, Python or Go bindings of the same workflow

What each one is
CloakBrowser
CloakBrowser is a modified build of the Chromium browser that changes browser fingerprint details at the source-code level, so websites are less likely to flag it as automated. It is designed to be used through the Playwright or Puppeteer API, so existing automation code needs only a small import change. People use it for web scraping and browser automation on sites with bot protection.
Stagehand
Stagehand is an SDK that lets code drive a real web browser using plain-language instructions alongside Playwright-style methods. You can ask it to observe elements, act on a page (such as clicking a button), or extract data into a schema you define. Sessions such as login cookies can persist between runs.
Best for
CloakBrowser
- Python or JavaScript developers already using Playwright who need automation to get past bot checks
- Scraping projects blocked by Cloudflare Turnstile or similar anti-bot systems, paired with a residential proxy
- Teams building AI agents that drive a real browser and hit bot detection
Stagehand
- Developers building browser agents that must work on sites they do not control
- Teams extracting structured data from web pages that lack an API
- Engineers who already know Playwright and want AI-assisted steps
- Projects needing TypeScript, Python or Go bindings of the same workflow
Strengths
CloakBrowser
- Source-level patches are described as harder for detection sites to spot than JavaScript injection
- Drop-in API compatibility with Playwright and Puppeteer reduces migration effort
- Active project with recent releases and a large star count
Stagehand
- Familiar Playwright-style API for developers already using it
- Returns schema-validated data from extract() calls
- Available in TypeScript, Python and Go with MIT license
Not ideal for
CloakBrowser
- People who need CAPTCHAs solved automatically: the README says it prevents CAPTCHAs from appearing and does not include solving services
- Users who need built-in proxy rotation: the README says you must bring your own proxies
- Anyone wanting a no-code tool: it requires writing Python or JavaScript
Stagehand
- People who only need fixed scripted browser tests with no AI, since the README centers on model-driven steps
- Non-programmers, because the examples require writing code and an API key for a model provider
- Users without Chrome installed for local runs, since the README says local runs need it
Trade-offs
CloakBrowser
- The core claim of passing every bot test is marketing language; the README reports results from its own tests against 50+ sites
- Best results require a paid Pro build for some features such as the higher reCAPTCHA score; the free build is described as the latest but its scope is less clear
- The binary is about 200MB and downloads on first run
Stagehand
- Relies on a third-party model provider and its API key, so usage has external cost and data flow
- README is truncated, so full feature and configuration details could not be verified here
- Model-driven actions can behave differently across sites and runs
