Database Configuration
Myrm keeps all of its data in one data directory:MYRM_DATA_DIR (default ~/.myrm). No external database or vector service is needed.
Only one running copy of Myrm can use a data directory at a time, because the embedded vector store locks its folder. A second copy that cannot open it keeps running, but it does not save new memories permanently and shows a warning in the app.
Graph store (optional)
DATABASE_URL points to an optional Apache AGE (PostgreSQL) graph store. Leave it empty to keep the graph in SQLite inside the data directory.
