Rules, skills, MCP servers, subagents and memories — in sync across every machine and every harness. Open source, self-hosted, entirely yours.
Apache-2.0 local engine · AGPL-3.0 server · GitHub opens at launch
mddb core · open source
Everything that touches your machines is open source: the sync engine, the MCP host, the CLI, every adapter and the config schema. Self-host the server with no limits, audit every line, export everything and leave anytime. Core is the foundation both Orbit and Fleet stand on.
what that buys you
The server and dashboard are AGPL-3.0 and yours to run. Self-hosting lifts every quota: unlimited devices, unlimited profiles, on infrastructure you control.
The local engine, CLI and MCP host are Apache-2.0. Every line that touches your files is readable before it runs — and after.
Your data exports with one command. Leaving for a self-hosted server — or away from mddb entirely — is a feature, not a support ticket.
