Start your server
Run one Docker Compose command. OvertChat brings the app, SQLite database, resume buffer, web search, and text-to-speech.
Open source · self-hosted
Your therapist has confidentiality.Now your chat app does too.
OvertChat is a complete chat client for hosted and local models, running on a server you own. Your account and chat history stay there; model requests go only to the endpoints you choose.

How it works
Your server is the product.
OvertChat keeps your account, chat history, and files on your server. Model requests go directly to the local or hosted endpoints you configure—never through an OvertChat-operated relay or control plane.
Connect your models
Add a hosted provider or an OpenAI-compatible local endpoint. The setup wizard checks the connection before you begin.
Chat from anywhere
Use the responsive web app or connect the native mobile client to the server you control. Your account, chat history, and files stay on that server.
What’s in the box
The whole client, already wired up.
Fast, persistent chat
Streaming replies, resumable generations, editable messages, projects, and automatically titled history.
Useful search
Search the web through bundled SearXNG and find old conversations with SQLite FTS5—no vector database required.
Rich attachments
Work with images, PDFs, Word and Excel documents, CSV files, and source code directly in a conversation.
Voice, both ways
Bundled text-to-speech works out of the box. Optional local speech-to-text keeps dictation on your hardware.
Model flexibility
Native support for OpenAI, Anthropic, Google Gemini, and Amazon Bedrock, plus any OpenAI-compatible endpoint—hosted or on hardware you own.
Private by construction
No usage analytics, advertising SDK, or hosted account system. The server belongs to you.
Deliberately boring infrastructure
Easy to understand. Easier to keep.
There is no distributed services diagram hiding behind the chat box. Back up one database file, update one container image, and keep operating on your terms.
Read the deployment guide- One application process
- One portable SQLite file
- A small Redis resume buffer
- No RAG or embeddings stack
- No plugin runtime

On the web
Open it and get to work.
A responsive interface for long conversations, projects, files, web research, voice, and every model connected to your server.
Self-host the web appOn mobile
Your server, in your pocket.
The native client connects directly to your OvertChat instance. Chats and attachments stay on that server—not in a hosted mobile backend.

From clone to chat in one stack.
Docker and an LLM endpoint are the only real prerequisites. The first account becomes the administrator and the setup wizard handles the rest.
