!CAUTION This is a proof of concept and has not been tested against image recognition yet, to keep your system secure use an already prooven secure captcha. However if you have the skills or resources to run image recognition on some samples please see examples/ for some sample outputs.

open-captcha

Open Captcha stands out from other captcha providers in a big way. Forget about connecting to external services or making your users work for free to train AI. Our approach ensures that each challenge is unique and employs the most advanced anti-ai detection methods, all while being completly self-hosted and intergrated into your web-app.

Benchmarking

To benchmark yourself run the script npm run benchmark

System dependencies

In most cases setting up open-captcha from npm should just work. However, since open-captcha uses image rendering you may run into problems and you might need to adjust your system configuration and make sure all your dependencies are up to date. For general information on building native modules, see the node-gyp documentation.
