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

Hello HN, I made this silly project over the long weekend. It’s pretty basic right now and the captchas are very easy. I plan to add captcha difficulty levels for link creators soon.

Make senders work to get into your inbox▲44
Hi HN :) really excited to share this with you. The one thing AI reliably does is generate noise. Half the tools I see launch are just machines for producing more noise across more channels. And people are starting to see this in the form of emails in their inboxes as spam filters are struggling. There used to be a useful signal in email: the effort a sender put into customizing a message was a rough proxy for how relevant it actually was. AI killed that. Now it's customized slop with the appearance of effort with none of the cost. It is painful that the open internet / open channels…

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...
