What is interesting is that both Codeberg [0] and Gitea [1] are working on integrating mCaptcha, but for reasons of improving the accessibility, which isn't mentioned on the site as key feature.

With the #GiveUpGithub [2] of the Software Freedom Conservancy both Codeberg and Gitea saw an uptick in people moving their FOSS projects to them. But accessibility on Github is still better. There were complaints on the CAPTCHA used (think it was Cloudflare hCaptcha). See the status report for info [3].

Hello!

I'm the author of mCaptcha. I'd be happy to answer any questions you might have :)

For context, mCaptcha was discussed in these threads in the past hour before being posted on here: [0]: https://news.ycombinator.com/item?id=32339922 [1]: https://news.ycombinator.com/item?id=32340424 [2]: https://news.ycombinator.com/item?id=32340305

https://mcaptcha.org/docs/prologue/introduction is a 404. (It's the link behind the "Get Started" button.)

A one-sentence describing exactly what it does and how it works would help ;-)

yikes! The docs had an overhaul last week, that link was removed as part of the overhaul. Should have paid more attention. Should be fixed now :)

Here goes nothing:

mCaptcha is a privacy-focused, highly accessible CAPTCHA that uses Proof of Work for rate-limiting. It makes the bot/spam spend more time and work sending the request than it takes for the server to respond.
