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

Procaptcha – Open-source, privacy preserving and frictionless CAPTCHA▲8
We built Procaptcha to make sure there's an actually good alternative to Google's ReCAPTCHA that's not a complete nightmare for the end user. Crucially we're not just a giant ad network like almost all CAPTCHA providers [1]. Like with other CAPTCHA providers it's simple to set up, you just change a couple of tags [2]. We've got a few different CAPTCHA types at the moment, all running on a distributed network of nodes with no user tracking. [1] https://prosopo.io/articles/stop-giving-your-website-data-aw...

Secure ChatGPT – a safer way to interact with generative AI▲35
Hi HN, I’m the founder of Pangea. We’ve built a developer platform where you can easily add security to your code through a simple set of APIs - features like authentication, secrets management, audit logging, redaction of PII, restricting embargoed countries, known threat actor intelligence, etc. With the ChatGPT and LLM explosion, we thought of ways to reduce the risk of both the inputs and outputs from these services. Our NextJS sample app adds a security layer on top of ChatGPT with various security services that you can implement quickly. It’s basically a front end to the OpenAI API…
