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.

A few years ago, right after high school, I decided to try to make a simultaneous translation app for Android as a side project, it took longer than expected (about 2 years) and I had to make a lot of compromises (I had to use Google's API and therefore make users use a developer key because at the time there were no free solutions for speech recognition and translation that had good quality). At the end of university, I decided to pick it up again and finally, using OpenAi's Whisper for speech recognition and Meta's NLLB for translation (with both running locally on the phone), I managed to…

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...

You can get a 2h free trial by solving a proof-of-work captcha when topping up your account for the first time. If you'd like to learn more, an independent interview was posted a couple of weeks ago [1], and the FAQ [2] has a lot of information as well. For the source code sharing, we've talked with lawyers and are inclined to no longer require the NDA/NCC for privacy reasons shared with us before (signing requires identification), but instead use a source-available permissive license that doesn't allow competition, like PolyForm Shield [3] (we do still have about 6 months before…

Hey everyone! We launched the first version of Cap earlier this year. It wasn't great. We had tons of feedback. A couple of months ago we started rebuilding Cap from the ground up (Tauri V2 + SolidJS). We're now focused on being local first. Cap is 100% free to use locally. New features include a powerful editor, screenshots, hotkeys and just overall a much better experience. Would love for you to test it out - appreciate you! Cheers, Richie
