24 alternatives to CodeCaptcha - Hide web links behind coding challenges

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.

CodeCaptcha is a tool that requires users to solve coding challenges before accessing web links. It's designed for developers who want to add an extra step before sharing URLs. The current version features basic… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    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

    Small team down here in South New Zealand just launched CodeLink. In short its an IDE (VSCode/JetBrains) plugin that lets you share blocks of code that link directly to the code inside your IDE or repo. We use it all the time and think its pretty nifty tech that lets you understand someone’s code in context very quickly. we’re hoping to keep refining it to make it better and more useful.

    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...
