CapSkip is a desktop CaptchaFox solver that runs on your own Windows machine or VPS rather than sending every widget to a remote solving farm. Give it the site key and the page URL and it returns the token the page's cf-captcha-response field expects, whether CaptchaFox lets the visitor through quietly or puts a challenge in front of them first.
Per-solve services such as 2Captcha and SolveCaptcha bill CaptchaFox at roughly $1.45 per 1,000 solves, and a widget that sometimes needs a second attempt turns that into a moving target. With CapSkip the bill is fixed in advance: $10/mo on Bronze, $17/mo on Silver or $20/mo on Gold, plus the $99 one-time lifetime license, with unlimited solving and threads on all three, so a retry costs you nothing.
A CaptchaFox token is tied to the browser that produced it, so CapSkip returns that browser's User-Agent alongside the token and your request should carry the same one. Use the no-code Chrome and Firefox extension, the official Python, Node.js, PHP and .NET SDKs, or the local HTTP API that emulates 2Captcha, RuCaptcha, Anti-Captcha, CapMonster, CapSolver and more, so an existing CaptchaFox integration usually needs no code changes.
No coding required. Run the CapSkip app and the browser extension connects automatically, then solves CAPTCHAs right in the page. Already using another service? Migrating is easy: CapSkip is a drop-in captcha solver that emulates 2Captcha, RuCaptcha, Anti-Captcha, CapMonster Cloud, CapSolver, DeathByCaptcha, SolveCaptcha and Captchas.io. Add your service to the hosts file in the CapSkip app and your existing code is routed to CapSkip and solved locally, with no changes.
CaptchaFox solver for silent passes and slide challenges
Flat rate, retries included
When CaptchaFox draws one of its rare unsupported challenges, you simply resubmit. On a flat plan from $10/mo plus the $99 lifetime license, that second attempt costs nothing.
Domain mismatches caught early
CaptchaFox ties every key to its registered domains. CapSkip reports a page URL outside that list as a permanent failure instead of retrying it, so you fix the URL rather than wait.
Silent pass or challenge
CaptchaFox usually clears visitors silently and sometimes asks for a slide. CapSkip handles both from the same API call; the rare image and audio challenges are reported so you can resubmit.
Local and private
Solving happens on your own hardware. The target URL, the site key and the token never leave your network for a third-party solving farm.
Two API shapes, no rewrite
CaptchaFox clients built for 2Captcha keep working: CapSkip answers the form API (method=captchafox) and the JSON task (CaptchaFoxTask) exactly as they arrive.
Extension and SDKs
A no-code browser extension for Chrome and Firefox, plus official Python, Node.js, PHP and C# SDKs and an MCP server for AI agents.
Three ways to bypass CaptchaFox
from capskip import CapSkip
solver = CapSkip(host="127.0.0.1", port=8080)
# sitekey is the data-sitekey on the widget, conventionally prefixed sk_.
result = solver.captchafox(
sitekey="sk_your-site-key",
url="https://example.com/signup", # the page the widget runs on
)
# Post the token in the cf-captcha-response field, under the same user agent.
print(result["token"], result.get("userAgent"))Solve a CaptchaFox widget in a few lines with the CapSkip Python SDK.
No-code browser extension
Install the CapSkip extension and it detects the widget on any page and solves it for you, with nothing to script.
Official SDKs
Automate solving from your own code with the Python, Node.js, PHP and C# clients. A few lines returns a valid token.
Local HTTP API
Prefer raw HTTP? CapSkip exposes a local endpoint with 2Captcha and Anti-Captcha API emulation, so any HTTP client works.

How to bypass CaptchaFox
Begin by reading the site key. A CaptchaFox key is conventionally prefixed sk_ and sits on the widget element as data-sitekey, or in the options passed to the widget when the page renders it from script. Add the full URL of the page the widget runs on, which must belong to one of the domains the key is registered for, and CapSkip has what it needs. Send them through the Python, Node.js, PHP or .NET SDK, or through the local 2Captcha-compatible HTTP API, and CapSkip returns the token to write into the page's hidden cf-captcha-response field before you submit the form.
Submit the token under the User-Agent it was issued to. This is the single most common reason a correct CaptchaFox token is rejected: the token is bound to the browser that produced it, and a request sent with a different User-Agent string looks like a replay. CapSkip returns the right one alongside the token on every API shape, so copy it into your client's headers rather than leaving your automation's default in place. The same applies to a proxy: if you solve through one, submit through it too.
Switching from another service does not mean rewriting anything. CapSkip answers the 2Captcha and RuCaptcha form API with method=captchafox on in.php, and the JSON task CaptchaFoxTask (and CaptchaFoxTaskProxyless) on createTask, which between them cover the CaptchaFox calls that 2Captcha-style and Anti-Captcha-style clients send. Once you add the hosts file entry from the CapSkip app, your CaptchaFox client talks to your own machine without any change on its side. In a normal browser, the extension clears the widget with no code at all.

Which page URL should I send with a CaptchaFox task?
The full URL of the page the widget actually runs on. CaptchaFox checks its host against the domains the site key is registered for and refuses a mismatch every time, not now and then, so retrying the same URL will not help.
How does a CaptchaFox bypass work in practice?
Read the widget's data-sitekey from the page, pass it and the page URL to CapSkip through an SDK or the local HTTP API, and write the returned token into the hidden cf-captcha-response field before submitting. Without any code, the Chrome or Firefox extension does all of this on the page itself.
Where do I find the CaptchaFox site key?
On the widget element as data-sitekey, or in the sitekey option the page passes when it renders the widget from script. It is conventionally prefixed sk_.
Why is my CaptchaFox token rejected even though it solved?
Almost always a User-Agent mismatch. The token is bound to the browser that produced it, so submitting it under a different User-Agent looks like a replay. CapSkip returns the correct User-Agent with the token, so send the token under that one, and through the same proxy if you used one.
Does CaptchaFox always show a challenge?
No. CaptchaFox often verifies quietly with nothing for the visitor to do, and shows an interactive challenge only when it wants a second look. CapSkip handles both from the same API call, so your code does not need to branch.
How do I get the CaptchaFox token and User-Agent in Python?
Install the SDK with pip install capskip and call solver.captchafox() with the sk_ site key and the page URL. The result holds the token for cf-captcha-response and, when the solve reports one, the userAgent to send it under.
Will my 2Captcha CaptchaFox client work with CapSkip?
Yes. CapSkip answers both CaptchaFox shapes: the 2Captcha form API (method=captchafox on in.php) and the JSON task (CaptchaFoxTask on createTask). Once you press Add to hosts file in the CapSkip app, that code is answered on your own machine without edits.
Does CaptchaFox solving work with a proxy?
Yes. Attach a proxy to an individual request, or keep a list of proxies in the app. HTTP, HTTPS, SOCKS5 and SOCKS5H are all supported, and solving through the same proxy you submit through is the safest pattern.
Is CaptchaFox solving billed per token?
Not with CapSkip. Per-solve services charge roughly $1.45 per 1,000 CaptchaFox solves, while CapSkip covers every token, retries included, with a monthly plan from $10 plus a $99 one-time lifetime license. The $1 trial runs 7 days and includes 1,000 solves.
Which CaptchaFox challenges can CapSkip solve?
The invisible check, which is what most visitors get, and the slide challenge CaptchaFox sometimes adds. The rare image-select and audio challenges are not supported; a retry usually draws a different challenge, so treat that result as a cue to resubmit.
Ready to bypass CaptchaFox?
Run CapSkip on your own machine, send the sk_ key and page URL, and submit the token under the User-Agent it comes back with. Every solve and every retry sits on the same flat plan.
