Captcha Solver Extensions for Chrome
Three kinds of CAPTCHA solver extension for Chrome work, each on a different set of challenges. Buster is free and open source (GPL-3.0) and answers reCAPTCHA audio challenges with speech recognition; it stops working when reCAPTCHA no longer offers your browser the audio option. NopeCHA is a commercial service with a free allowance of up to 100 recognitions every 24 hours for personal use, then plans from $4.99 a month. The solver services' own extensions, such as 2Captcha and CapSolver, need an API key and a paid balance. Free does not mean safe: a solver must read and change the pages you visit, so install one only from its official store listing, limit its site access, and keep it out of the Chrome profile you use for banking or email. ProxyField sells no solver; if a flagged IP is what brings the CAPTCHAs, its residential proxies (412M+ IPs, from $1.95/GB) are one fix, and you can start with the Easy Trial: 1 GB for $2.95.

CAPTCHA solver extensions that work, compared
From each project's own page. Prices and limits change, so check them again before you pay.
| Extension | How it solves | Cost | Handles | Needs | Source |
|---|---|---|---|---|---|
| Buster: Captcha Solver for Humans | Opens the audio challenge of a reCAPTCHA and transcribes it with speech recognition; you start it with a button under the widget | Free, open source (GPL-3.0) | reCAPTCHA audio challenges | Nothing; an optional client app for Windows, Linux and macOS simulates user input and, per the project, improves its success rate | github.com/dessant/buster |
| NopeCHA | Sends the challenge to NopeCHA's recognition service and fills in the answer | Free for personal or hobby use, up to 100 recognitions every 24 hours; paid plans from $4.99/month (2,000 solves a day) | NopeCHA's site lists reCAPTCHA, hCaptcha, FunCAPTCHA, AWS WAF, GeeTest and text CAPTCHAs | A NopeCHA account and key for more than the free allowance | nopecha.com, pricing |
| 2Captcha extension | Front end of the 2Captcha solving service | Paid per solve from your 2Captcha balance | reCAPTCHA v2, v3, invisible and Enterprise, FunCaptcha, GeeTest and others, per its page | Your 2Captcha API key | 2captcha.com/captcha-bypass-extension |
| CapSolver extension | Front end of CapSolver's AI service | Paid per solve from your CapSolver balance | reCAPTCHA v2 and v3, image-to-text, AWS WAF, Cloudflare Turnstile, per its docs | A CapSolver API key | docs.capsolver.com |
Buster also has Firefox, Edge and Opera listings; the 2Captcha and CapSolver pages list Chrome and Firefox, with other browsers marked "coming soon" or "planned". What each solver service charges per 1,000 solves, with the API pattern a script uses: CAPTCHA solver services compared.
Which one to pick
- You meet a reCAPTCHA now and then while browsing: Buster. It costs nothing and its code is public. Expect it to fail on the days reCAPTCHA hides the audio option from your browser.
- You meet several CAPTCHA types (hCaptcha, image grids, text): a service-backed extension. NopeCHA's free allowance covers light personal use; 2Captcha and CapSolver charge per solve from the first one.
- You run a script, not a browser: no extension. Call a solver service's API from the script instead (CAPTCHA solver services compared).
- You keep getting CAPTCHAs on every site: fix the trigger first (a flagged VPN, blocked cookies or JavaScript, an old browser). How to avoid and solve CAPTCHAs has the visitor checklist.
What works, and what doesn't
| Challenge | Free audio solver (Buster) | Service-backed extension |
|---|---|---|
| reCAPTCHA v2 checkbox and image grid | Yes, through the audio option | Yes |
| reCAPTCHA v2 audio blocked for your browser | No | Yes, if the service solves the image task |
| hCaptcha image tasks | No | If the service lists hCaptcha (NopeCHA does) |
| Text CAPTCHAs | No | Yes, on most services |
| reCAPTCHA v3 | No: nothing is shown to solve | Some services return a token, but the site still decides on the score that comes with it |
| Cloudflare Turnstile, non-interactive or invisible | No: it runs browser checks instead of a puzzle (Cloudflare: Turnstile) | Some services list Turnstile tokens; the page's own checks still run |
| A site that challenges every page | Rarely: it has already flagged the browser | Rarely, for the same reason |
No extension changes why the CAPTCHA appeared. If your IP, your browser or your request rate looks risky, the site keeps asking. For Cloudflare's "Verify you are human" page in particular, see Cloudflare human verification bypass extensions.
Are free CAPTCHA solver extensions safe?
They can be, but the risk is real, because a solver needs broad access to work. To find CAPTCHAs on any site it usually asks to "read and change all your data on all websites", which lets it see what you type on every page, passwords and payment forms included.
What the Chrome Web Store does and does not promise:
- Review is not a guarantee. Chrome reviews new extensions and updates with "a combination of manual and automated systems", usually within a few days, and reviews published items again from time to time; an extension that breaks the rules is taken down after the fact (Chrome Web Store review process). Extensions that request broad host permissions such as
<all_urls>may take longer to review, because those give "extensive access to the user's web activity". - The data policy binds the publisher, not the code. The Limited Use policy says extensions may only collect user data "necessary for the extension's disclosed single purpose" and bans selling it to advertising platforms or data brokers (Chrome Web Store: Limited Use).
The risks to weigh:
- Ownership changes. Extensions get sold, and an update can add tracking or ads to an extension you installed years ago.
- Your account key. A service front end stores your API key; anyone who gets it can spend your balance.
- Copycats. Search results and the store carry look-alike "free AI CAPTCHA solver" extensions. Install only from the link on the project's own site or repository.
- Site terms. Some sites forbid automated solving, and an account that solves every CAPTCHA in a second can be flagged.
Five checks before and after you install:
- Get it from the official listing, linked from the project's own site or GitHub page, not from a search ad or a ZIP file.
- Compare the permissions with what it needs. A solver needs access to the pages with CAPTCHAs. Access to your browsing history, downloads or cookies on every site is more than that.
- Limit its site access. In Chrome, open the extension's details and set "Site access" to "On click" or "On specific sites", so it runs only where you allow it.
- Check the publisher and the code. A named company with a privacy policy, or an open-source project with public code and recent commits (Buster's repository is public).
- Use a separate Chrome profile for the solver, not the one you use for banking, email or work accounts.
Free CAPTCHA solvers: what you get
"Free" means one of three things:
- Open source and free: Buster. It answers reCAPTCHA audio challenges and stops when the CAPTCHA withholds audio from your browser.
- A free allowance: NopeCHA's free use, up to 100 recognitions every 24 hours for personal or hobby projects; then paid.
- Free with your data: an extension paid for some other way, through ads, tracking or reselling data. This is the kind to avoid.
If you only meet CAPTCHAs now and then, the free fix is often the trigger itself: turn off a flagged VPN, allow cookies and JavaScript, and update the browser.
Can you use a solver extension for web scraping?
For a few pages in a browser you drive by hand, yes. For scraping at volume, no: an extension solves one page at a time in a visible browser, and it adds its own permissions and update risk to every automated browser you run. Scrapers call a solver service's API directly, submit the token from the script, and give the solver the same proxy as the scraper, so the solve and the submit come from one IP.
If your IP is what triggers the checks, set a residential proxy in Chrome: setup is on the Chrome proxy integration page, and what proxies change for CAPTCHAs is in CAPTCHA proxies.
Where solver extensions cross the line
Solving a CAPTCHA to read a public page you could open anyway is different from solving CAPTCHAs to sign up accounts in bulk, post spam or buy limited stock, which is the abuse CAPTCHAs exist to stop and what most sites' terms forbid. ProxyField's acceptable use policy forbids fake accounts, fake engagement and fraud: public pages only, and follow the site's terms. For public-data scraping, see is web scraping legal.

Captcha Solver Extensions for Chrome FAQ
Which CAPTCHA solver extensions for Chrome actually work, and are the free ones safe to install?
ProxyField sells no solver (its residential proxies start at $1.95/GB), but three kinds work: Buster, free and open source, for reCAPTCHA audio challenges; NopeCHA, with up to 100 free recognitions every 24 hours for personal use and plans from $4.99 a month; and service front ends such as the 2Captcha and CapSolver extensions, paid per solve. Free ones are safe only as far as their publisher: install from the official listing, set Chrome's site access to "On click" or chosen sites, and use a separate profile.
Is there a free CAPTCHA solver?
Yes. Buster is free and open source and answers reCAPTCHA audio challenges with speech recognition, and NopeCHA allows up to 100 recognitions every 24 hours for personal or hobby use. Both work only on challenges that show something to solve.
Can I solve CAPTCHAs for free?
By hand, always: every major CAPTCHA has a visual and usually an audio option. Automatically, only with a free audio solver such as Buster or a service's free allowance, and with the privacy risk that comes with broad extension permissions.
Why are some CAPTCHA solver extensions free?
Some are open-source projects such as Buster; some give a free allowance to sell a paid plan, as NopeCHA does; and some are paid for with your data, through ads, tracking or reselling. Read the privacy disclosure and the permissions to tell which kind you have.
Are CAPTCHA solver extensions safe?
Only as safe as their publisher. They usually need permission to read and change all your data on all websites, and the Chrome Web Store reviews extensions but takes down bad ones only after the fact. Install from the official listing, limit site access, and keep the solver out of the profile you use for banking or email.
What is Buster, the "Captcha Solver for Humans"?
Buster: Captcha Solver for Humans is a free, open-source (GPL-3.0) browser extension for Chrome, Firefox, Edge and Opera that answers reCAPTCHA audio challenges with speech recognition. It works on reCAPTCHA audio challenges only: it fails when reCAPTCHA stops offering audio to your browser and does nothing for hCaptcha, text CAPTCHAs, reCAPTCHA v3 or Turnstile.
Can an extension solve CAPTCHAs automatically?
Yes, for visible challenges: service-backed extensions such as NopeCHA, 2Captcha and CapSolver fill in the answer without a click, and Buster solves the audio challenge after one click. No extension can make a site stop checking: invisible score-based checks still decide from your IP, browser and behavior.
Which CAPTCHAs can a solver extension handle?
Visible ones: reCAPTCHA v2 checkbox, image and audio challenges, hCaptcha image tasks with a service that lists them, and text CAPTCHAs. Some services also return tokens for reCAPTCHA v3 and Turnstile, but the site still scores the session behind the token.
Do CAPTCHA solver extensions always work?
No. They fail when the challenge type isn't supported, when the CAPTCHA blocks the audio option, when the token arrives too late, and when the site keeps challenging a browser it has already flagged.
Can I use a CAPTCHA solver extension for web scraping?
Only for a few pages in a browser you drive by hand. Scrapers call a solver service's API directly and pass it the same proxy the scraper uses, which scales and keeps the IP the same from solve to submit.
