Deploy Letta in one click installation.
Open-source framework for building stateful AI agents with persistent memory that learn and improve over time.
What you can build with Letta
Letta is an open-source framework for creating AI agents with long-term memory, enabling them to learn from conversations and improve over time. Unlike stateless chatbots, Letta agents maintain memory blocks that persist between sessions, recall user preferences, and adapt their behavior based on accumulated experience.
Self-hosting Letta on your VPS gives you full control over agent data and memory, eliminates per-request API costs for memory management, and lets you integrate any LLM provider — from OpenAI and Anthropic to locally-hosted Ollama models — without vendor lock-in.
Key features of Letta
Persistent agent memory
Agents retain context between sessions using structured memory blocks, so they never forget past conversations or user preferences.
Multi-provider LLM support
Connect to OpenAI, Anthropic, Groq, Ollama, and more — swap models without changing your agent logic.
REST API and SDKs
Full REST API with Python and TypeScript SDKs for integrating stateful agents into any application or workflow.
Multi-agent orchestration
Build complex pipelines with agent-to-agent communication, shared memory, and coordinated task execution.
Tool execution
Agents can call custom tools and execute code in sandboxed environments to act on the real world.
Memory self-editing
Agents update their own memory blocks in real time, enabling continuous self-improvement and adaptive behavior.

Docker VPS hosting you can rely on
I'm incredibly happy with Hostinger's VPS hosting! Their uptime is consistently top-notch, keeping my site running smoothly. Whenever I've needed help, their technical support team has been quick, knowledgeable, and genuinely helpful.
Everything is smooth and great with Hostinger, the AI chat bot + human chat, if AI can't resolve your question. Oh and them VPS is just fire, no ups and downs. Thank you dev team and everyone else involved. Keep it up 🚀
Finally a VPS hosting company that does it right! Well-priced. Excellent portal that respects their users' time. Seamless backups. Good support. Reliable. Feels rock-solid.
I reached out to Hostinger support after losing access to my self-hosted n8n instance, and I couldn’t be more impressed. Hostinger Agent and Mohammad from the support team were incredibly patient and thorough.
Many thanks to Carla for helping me with this N8N upgrade on my Hostinger VPS. Professional and knowledgeable, thank you again Carla.
Hostinger VPS is absolutely outstanding. It just always works. It is always fast and stable. Never down, never crashes.
The company is doing well, I am very happy with the specific services I use through them. Not as expensive as some places with really great VPS set ups and price plans.
