Vane is an open-source ai chat project by ItzCrazyKns (ItzCrazyKns/Vane on GitHub). It has 37,143 GitHub stars and 4,124 forks, is released under the MIT license, and was last updated on GitHub on 1 September 2026.
Decide what you want to achieve with Vane and check the README on GitHub for requirements before installing.
Clone the repository from GitHub (or take the packaged install route in step 3 if the README offers one).
Follow the project's documented install commands — the Run section below lists the exact ones — and add any required API keys or models.
Work through the README's quickstart example end to end, then adapt it to your own project or data.
Questions are answered from live web results with citations, not just model memory.
Uses the privacy-respecting SearXNG metasearch engine under the hood.
Search modes for different sources plus a discovery feed, mirroring the hosted AI-search experience.
Can be set as your browser's default search engine, and exposes an API for programmatic queries.
Works with local LLMs through Ollama or hosted providers — your choice per deployment.
Ships an official Docker image (itzcrazykns1337/vane) including a slim variant with an external SearXNG URL.
Get the Vane source if you prefer building/configuring from source.
git clone https://github.com/ItzCrazyKns/Vane.git
cd VaneStart Vane with the published image; it serves on port 3000 with a persistent data volume.
docker run -d -p 3000:3000 -v vane-data:/home/vane/data --name vane itzcrazykns1337/vane:latestOpen http://localhost:3000, choose your LLM provider (e.g. Ollama or a cloud API) in settings, then ask your first question.
# configure the provider in the web UI at http://localhost:3000Vane is maintained by the ItzCrazyKns organization/account on GitHub, together with open-source contributors, in the public repository ItzCrazyKns/Vane.
Yes — the code is open source under the MIT license. You can use, modify and redistribute it under that license's terms.
Vane itself is free; you can run it fully locally with Ollama at no cost, or plug in a paid cloud LLM API key if you prefer hosted models.
Perplexity is a polished hosted product; Vane gives you a similar answering-engine experience self-hosted and free, but you run and maintain the server yourself.
Clone the repository from GitHub, follow the install commands in the Run section (taken from the project's README), and complete the documented quickstart example before adapting it to your own use case.
