Captchas solved
in your own browser

What it solves

• reCAPTCHA v2 checkbox — Solved as soon as the widget appears. $2.85 per 1,000 successful solves.
• reCAPTCHA v2 invisible — Solved when the site asks for a token, usually when you submit. $2.85 per 1,000 successful solves.
• reCAPTCHA Enterprise — Checkbox-style Enterprise widgets. $3.00 per 1,000 successful solves.
• reCAPTCHA v3 — Off by default. When on, the site's own execute() call gets a token for its action and your minimum score. $3.00 per 1,000 successful solves.
• Cloudflare Turnstile — Gets 5 seconds to pass on its own first; you only pay if it doesn't. $4.35 per 1,000 successful solves.
• Image / text captchas — Right-click the image, choose “Solve this captcha image with CaptchaNo”, and the answer is typed into the next empty field. $1.50 per 1,000 successful solves.

It does not solve hCaptcha, GeeTest, Arkose or DataDome. DataDome needs your own proxy through the API, and a cookie earned behind a proxy would not match your browser's IP. Failed solves are never billed.

Controls that keep spend predictable

• Daily spend limit, $2 by default. The extension stops solving for the day once it reaches it.
• Max solves per page, so a captcha that keeps resetting can't run up a bill.
• Per-site switch in the popup, plus a blocklist or allowlist in settings.
• Automatic or manual. In manual mode a small “Solve with CaptchaNo” button appears under each captcha.
• Auto-submit is off by default, so forms are never sent before you finish them.

Privacy

The extension talks only to the CaptchaNo API. For each solve it sends the page URL, the captcha's public site key, your browser's user agent and, for image captchas, the image. It has no analytics or tracking, and it reads no form fields, cookies or history. It asks for three permissions: storage, the right-click menu, and access to sites so it can see captchas. Your key stays in your browser. See our privacy policy.

Extension or API?

Use the extension for captchas in the browser you sit at. For headless browsers, servers, CI, n8n or AI agents, call the captcha solver API or connect the MCP server. The same key and balance work for all of them.

Only automate where you are allowed to: your own sites, systems you have permission to test, and data collection a site's terms permit. See the acceptable use policy.
