Agents that remember you
Letta agents keep learning between conversations. That memory deserves a server you own.
From the team behind MemGPT. Running 24/7 on your VPS.

What is Letta?
Letta is an open-source platform for stateful agents: AI with advanced memory that learns and self-improves over time. Built by the team behind the MemGPT research paper, it runs as a server exposing a REST API, with SDKs and a web development environment (the ADE) for building agents on top. The Docker image bundles the server and its PostgreSQL database, and models connect through your own API keys or a local Ollama endpoint.

Why run Letta on a VPS?
Memory that learns over time only pays off if the server is always there.
Memory that compounds
Letta agents edit their own memory and improve with every interaction. An always-on server means they never stop learning.
An API for your apps
The server exposes a REST API on port 8283. Your applications, scripts, and other agents talk to it around the clock.
Your agents' history, your disk
Everything the agents know lives in a PostgreSQL data directory on your NVMe volume. Back it up, move it, or delete it: it is yours.
You control what leaves
Your code and credentials stay on your European VPS. You pick which model provider gets your prompts, and how much context you share.

The server and its database run bundled in one container; models run through your API keys. Start small, grow with your agents.

Your Letta server in four steps
Deploy your VPS and install Docker
Choose Debian 12 or Ubuntu 24.04 at checkout, then install Docker with the official script.
curl -fsSL https://get.docker.com | sh Start the Letta server, secured
One container carries the server and its PostgreSQL database. On a remote server, always set a password.
docker run -d --restart unless-stopped -v ~/.letta/.persist/pgdata:/var/lib/postgresql/data -p 8283:8283 -e SECURE=true -e LETTA_SERVER_PASSWORD=yourpassword -e ANTHROPIC_API_KEY=your_key letta/letta:latest Reach it over an SSH tunnel
Keep port 8283 firewalled and connect from your machine through a tunnel, exactly as the official docs recommend.
ssh -L 8283:localhost:8283 you@your.server.ip Build your first agent
Point the ADE or the Python and TypeScript SDKs at http://localhost:8283 through your tunnel and create your first stateful agent. Its memory starts compounding from message one.
