Introducing OneContext. I built it for myself but now I can’t work without it, so it felt wrong not to share. OneContext is an Agent Self-Managed Context Layer across different sessions, devices, and coding agents (Codex / Claude Code). How it works: 1. Open Claude Code/Codex inside OneContext as usual, it automatically manages your context and history into a persistent context layer. 2. Start a new agent under the same context, it remembers everything about your project. 3. Share the context via link, anyone can continue building on the exact same shared context. Install with: npm i -g onecontext-ai And open with: onecontext Give it a try!
