open source · runs entirely on your machine
The local-first stack
for AI agents.
Persistent memory, MCP tooling, and token-cost control — three tools that give any LLM a memory that survives restarts, without a cloud in sight.

the stack
Three tools. One machine.
Each works on its own — they're better together.
Your data never leaves
SQLite on your disk. No sync, no telemetry, no accounts.
No API keys required
Runs against local models out of the box. Bring keys only if you want to.
Auditable by design
Open source, deterministic, and inspectable down to the storage layer.
get started
Run your agents like you own them.
Because you do. Clone, install, and go — no account required.
