Deploy and Host Letta on Railway

Letta is an open-source framework for building stateful AI agents with advanced reasoning and transparent long-term memory. It enables developers to create agents capable of learning, adapting, and interacting with large language models (LLMs) across diverse tasks and applications. The platform is model-agnostic, easy to extend, and supported by an active open-source community, making it ideal for building complex, memory-enhanced AI assistants.

About Hosting Letta

Hosting Letta involves setting up the Letta server (preferably via Docker) to manage one or more stateful agents. The Letta server can connect to multiple LLM API providers such as OpenAI, Anthropic, or Ollama, configured through environment variables. Railway’s managed infrastructure allows you to deploy the Letta server template with minimal friction, handling database persistence and environment setup. Once deployed, you can interact with your agents using REST APIs, SDKs, or the web-based Agent Development Environment (ADE). To maximize Letta’s capabilities, set up API keys for your preferred LLM providers and connect storage for persistent agent memory.
