Questions, answered

Who maintains this project?

It is maintained by the LangBot team (langbot-app) and contributors on GitHub.

Is it free to use?

Yes - LangBot is Apache-2.0 licensed and free to self-host. LangBot Cloud is an optional hosted service.

Does it need a paid API key?

The platform is free, but the LLMs behind your bot need their own accounts/API keys - or run local models via Ollama for free.

How does it compare to alternatives?

Compared with writing a bot per platform with each SDK, LangBot unifies platforms, models, RAG and plugins in one production-oriented system.

How do I get started?

Run uvx langbot, open localhost:5300, add a model and a platform, and send your bot its first message.
