Open-source platform for teams to run AI coding agents in isolated cloud sandboxes.

PlatformWebfreeglobal

143 is an open-source platform for teams to run AI coding agents like Codex, Claude Code, or OpenCode in isolated cloud sandboxes, connected to the team's own repos and shared context. It's built for teams that want to build software together with coding agents rather than running them individually with no shared infrastructure.
