Stop frustrating users with puzzles. Wicketkeeper is an open-source captcha that uses a fast Proof-of-Work challenge instead. Its self-hosted Go server generates tamper-proof JWTs for challenges and uses a Redis Bloom filter to block replay attacks. A simple JS client integrates into any form, solving the PoW in the background via Web Workers. Get powerful bot protection without sacrificing privacy or user experience.
