How do I install YaCy peer-to-peer search?

Pick a client above and copy the generated config. Cursor and VS Code also have a deep link when the server can run locally or remotely.

Is YaCy peer-to-peer search official?

No. Registry-listed is not the same as vendor-official. Read the methodology for the difference.

How is the trust score calculated?

This listing scores 52 (Fair). The formula is published on the methodology page.
