Isolated databases for every AI agent branch. Build, test, and migrate in parallel. Production stays untouched.
Database safety infrastructure for AFK agentic development.
SafeAgentDB is built for serious vibe coders shipping real products with a team — whether your teammates are people, AI agents, or both. Once you have many branches in flight at the same time, one shared database becomes the thing everyone breaks. SafeAgentDB gives every branch and PR a live preview URL backed by its own isolated database, so agents can run migrations, hydrate realistic data, and test real app behavior without risking production, corrupting shared development data, or stepping on each other.
Built first for Supabase + Vercel + GitHub Actions, with guidance for adapting the same infrastructure pattern to other stacks.
The goal of this proposal is to advance a superset of C++ with a rigorously safe subset. Begin a new project, or take an existing one, and start writing safe code in C++. Code in the safe context exhibits the same strong safety guarantees as code written in Rust.
Safe Eyes is a Free and Open Source tool for Linux users to reduce and prevent repetitive strain injury (RSI).
A small Python library created to help developers protect their applications from Server Side Request Forgery (SSRF) attacks. It implements an asynchronous GET method called safehttpx.get(), which is a wrapper around httpx.AsyncClient.get() while performing DNS validation on the supplied URL using Google DNS.

All PHP functions, rewritten to throw exceptions instead of returning false.
Most PHP core functions were written before exception handling was added to the language. Therefore, most PHP functions do not throw exceptions. Instead, they return false in case of error.
Safe-PHP redeclares all core PHP functions. The new PHP functions act exactly as the old ones, except they throw exceptions properly when an error is encountered. The "safe" functions have the same name as the core PHP functions, except they are in the Safe namespace.
