Deploy Cap Captcha on your own server.

Cerbos is an open-source authorization layer that lets you define context-aware access control rules for your application in simple YAML policies, managed through your existing Git-ops workflow. It runs as a stateless Policy Decision Point (PDP) that your backend services call over HTTP or gRPC to check whether a principal can perform an action on a resource, supporting everything from simple RBAC to fully dynamic, attribute-based rules.

mCaptcha is a proof-of-work based captcha system that prioritizes user privacy and offers a fully automated experience. Unlike traditional captcha systems, mCaptcha does not track or profile users, ensuring a privacy-focused user experience. It is designed to be robust and accurate, not relying on IP addresses for rate-limiting, making it suitable for users behind NATs. The user experience is silent and seamless, eliminating the need for annoying image-based captchas. mCaptcha uses a proof-of-work solution to fiercely defend your site, making it more expensive for attackers to target your site than for you to respond to their requests. It is a libre software, with client libraries licensed under proprietary-friendly free software licenses. mCaptcha is also compatible with reCAPTCHA and hCaptcha, making it a convenient drop-in replacement. The core functionality of mCaptcha is to use a SHA256 based proof-of-work system to rate limit users, providing a token upon successful validation that users can then submit with their request or form submission to the target website.

Ziit (pronounced 'tseet') is an open-source, self-hostable alternative to WakaTime. It provides a clean, minimal, and fast dashboard for displaying coding statistics, while ensuring privacy by keeping all data on your own server. Ziit tracks coding activity such as projects, languages, editors, files, branches, operating systems, and time spent coding, all presented in a familiar interface inspired by Plausible Analytics.
