How do I install onsystem?

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 onsystem official?

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

This listing scores 55 (Fair). The formula is published on the methodology page.
