Do I need a NoneCap account to use the extension?

No. The extension gives you 100 free solves a day, no signup. If you need more than that, add a NoneCap API key in the options and solving runs against your account balance.

What does the extension actually send?

Only what it needs to solve the challenge, and only while a challenge is open. It does not capture or send any screenshot of the page, and sends no page content. Full detail is in the extension privacy policy.

Is there a Buster extension for hCaptcha?

No. Buster works on reCAPTCHA's audio challenge, and hCaptcha doesn't serve an audio challenge, so Buster has nothing to solve there. On hCaptcha you need an extension that solves the visual puzzles, which is what this one does.

Which hCaptcha challenges can it solve?

Image grids, drag puzzles, and point-on-image challenges. It doesn't solve reCAPTCHA, Cloudflare Turnstile, or FunCaptcha.

Why does it ask for the debugger permission?

The extension uses it to solve the challenge inside the captcha frame. It attaches only during an active solve and detaches the moment the attempt ends. Chrome shows a "started debugging this browser" banner while that is happening.

Can I install it outside the Chrome Web Store?

Yes. Every release is published at github.com/nonecap/nonecap-extension. Download the zip, unpack it, and load it from chrome://extensions with Developer mode turned on.

How it works

When a captcha appears, the extension solves it and clicks through for you. It takes and sends no screenshot and no page content.

Privacy

The extension sends only what it needs to solve the challenge, never a screenshot or page content, and only while a challenge is open. It also sends an anonymous outcome ping (solved or failed, plus the round count) so solve quality can be monitored. It doesn't collect your browsing history or page content. The full policy is on the extension privacy page.

Why Buster doesn't solve hCaptcha

Buster is the extension most people try first, and it is a good one for reCAPTCHA. It solves reCAPTCHA's audio challenge by transcribing the clip. hCaptcha doesn't serve an audio challenge: its puzzles are visual (image grids, drag puzzles, and prompts to click a spot on an image), so Buster has nothing to work with. Plenty of sites moved from reCAPTCHA to hCaptcha, which is why people who relied on Buster find themselves clicking tiles again. For reCAPTCHA's audio challenge, Buster is still a reasonable free pick.

NoneCap extension vs Buster
	NoneCap extension	Buster
Captcha it targets	hCaptcha	reCAPTCHA
Challenges it handles	Image grids, drag puzzles, point-on-image	The reCAPTCHA audio challenge
Works on an hCaptcha widget	Yes	No
Free use	100 solves a day, no account	Free

Prefer to call the API directly?

The extension is the no-code way to use NoneCap. If you're automating a browser or a scraper instead, call the API yourself with a few lines of code, or use the official TypeScript SDK. The API reference has runnable examples in cURL, Node, Python, and Go, and the integration guides cover Playwright, Puppeteer, scraping, and AI agents.
