   Replace CAPTCHAs with WebAuthn passkeys for bot prevention▲71

   I built Nocaptcha after getting frustrated with traditional CAPTCHAs both as a user and developer. WebAuthn passkeys offered a promising alternative that's both more secure and user-friendly. What makes Nocaptcha different: - Uses WebAuthn standard instead of puzzle-solving - No need for users to remember passwords or solve puzzles - Open source Current limitation: Working with W3C WebAuthn Community Group on true passkey disposal for this use case. Looking for feedback particularly on: 1. Integration experience 2. User experience compared to traditional CAPTCHAs

    XHR anti bot bypass (xhr.dev)▲19

    I've launched the new product, xhr.dev (https://xhr.dev/) The initial product is a 1 line code integration that does bot detection avoidance via a forward proxy. Ideal customer is someone who gets blocked by anti-bot defences like cloudflare or other captcha challenges. Usually these customers have web scraping use cases. You can view our historical performance on our status page (https://status.xhr.dev). ty v much, john
