.NET / C# SDK
C# / .NET CAPTCHA Solver
Add the CapSkip .NET SDK with dotnet add package CapSkip and solve reCAPTCHA, Turnstile, GeeTest and image CAPTCHAs locally at unlimited flat-rate speed.
- Unlimited solving
- Local and private
- 90-100% accuracy
- One flat price
CapSkip is a C# CAPTCHA solver that runs locally on your own Windows machine or VPS instead of a remote per-solve API farm. Add it with dotnet add package CapSkip and solve reCAPTCHA v2, reCAPTCHA v3, reCAPTCHA Enterprise, Cloudflare Turnstile, GeeTest v3 and thousands of image CAPTCHA types directly from .NET.
Where 2Captcha, Anti-Captcha and CapSolver charge per 1,000 solves, CapSkip is unlimited flat-rate. A single plan ($99 one-time, then from $10/month) includes unlimited high-speed solving, unlimited threads and 90-100% accuracy with no per-solve billing. Image CAPTCHAs return in about 0.1 seconds, and because solving runs on your own machine the challenge data is never sent to a third-party human farm.
The .NET SDK fits console apps, services and Selenium-based automation, handling unlimited concurrent solves at a fixed monthly cost. If you already have 2Captcha or Anti-Captcha C# client code, CapSkip's local HTTP API emulation is drop-in compatible, so you keep your existing .NET code.
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.

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.

How to solve CAPTCHAs in C# / .NET
For a no-code option, install the CapSkip browser extension for Chrome or Firefox to auto-detect and solve widgets in the page. To solve from code, run dotnet add package CapSkip, then call the SDK with the site URL and site key for token CAPTCHAs (reCAPTCHA, Turnstile) or the image bytes for image CAPTCHAs; CapSkip solves locally and returns the token or text. Existing 2Captcha/Anti-Captcha C# code also works against CapSkip's local API emulation.
