What it is
NopeCHA is a browser extension that tries to solve CAPTCHA challenges automatically, so a page can keep moving without a person clicking through them. The README says it works with automation tools such as Selenium, Puppeteer, and Playwright. The project also offers an API, and its release notes mention many supported CAPTCHA types, including reCAPTCHA, Cloudflare Turnstile, PerimeterX, and AWS WAF.
- Run a Selenium or Playwright test suite against a staging site that shows CAPTCHAs
- Load the extension in a Chromium or Firefox automation profile and let it handle supported challenges
- Check pass-rate and solve-status diagnostics shown in the popup (added in 0.6.0)
Great for
- Developers building browser automation that runs into CAPTCHAs during testing
- Researchers testing how their own sites handle CAPTCHA challenges
- Teams already using Selenium, Puppeteer, or Playwright who want an extension-based solver
Not ideal for
- Anyone wanting to bypass CAPTCHAs on sites they do not have permission to automate, since this may violate site terms and the README does not address that
- People who need a fully offline tool, because the solving relies on the NopeCHA service and its API
- Non-technical users looking for a simple ad-blocker-style extension with no setup

Downloads
Strengths
- Actively maintained, with releases through 2026 covering many CAPTCHA types
- Works with several common browser automation frameworks according to the README
- MIT licensed and open source
Trade-offs
- Solving depends on an external service, and the README does not explain costs or limits in detail
- Some CAPTCHA support is labeled beta or specific to Chromium, so behavior may vary by browser
- Use on third-party sites may conflict with their terms, so users must judge that themselves
