Product explainer
What is Vane AI?
Vane is an open-source AI answering engine that you run yourself. Formerly called Perplexica, it combines web results from SearXNG with a model you choose to generate answers that cite sources. Its official project is maintained at ItzCrazyKns/Vane.
Project description and setup options checked October 22, 2026 against the official repository. This page explains the published architecture; it is not a hands-on performance review.
How an answer is made
- You ask Vane a question in its self-hosted interface.
- Its search layer uses SearXNG to retrieve web results.
- A configured local or cloud model reads the supplied context and drafts an answer.
- You open the cited source pages to check the claims.
This is why merely opening the Vane setup screen does not prove the complete system works. Search retrieval, model access, answer generation, and citation links should all be checked.
Models and deployment
Vane's documentation lists local-model support through Ollama and cloud-provider options. Its recommended Docker image bundles SearXNG; the documented one-container command is in our installation guide. If Ollama runs on the Docker host, the address visible from inside the container differs from the host's own localhost; see our connection guide.
Is Vane free?
The official package identifies the project as MIT-licensed. Running it can still use paid hosting or a paid cloud model, and a local model consumes computer resources. See the cost breakdown before describing a particular setup as free.
Who is it for?
Vane fits a person who wants a Perplexity-like web-answer workflow and is willing to run and maintain the service. It is less convenient if you need a hosted product with no setup. If you mainly want a chat workspace, a document assistant, a research agent, or only raw search results, the alternatives comparison separates those tool types.
Limits to understand
- Answer quality depends on retrieved sources and the selected model; a citation is a link to inspect, not automatic proof.
- Self-hosting does not make external web search offline.
- Using a cloud model can send data to that provider.
- You are responsible for updates, availability, and access control on your own installation.
Is Perplexica a separate product?
No. The project's README identifies Vane as formerly Perplexica. The name-change guide explains what to check when an older tutorial still says Perplexica. This independent site is neither the official Vane project nor a Vane hosting service.
