Run a browser session

Open the site and press Join the swarm. Your browser downloads a small signed WebAssembly build of the current target and starts mutating inputs inside a Web Worker. The activity panel switches to your machine and counts the tests you run and the new paths you reach. Close the tab and it stops. That is the entire commitment.

Run the desktop client

The browser worker handles lighter WebAssembly targets. For native C and C++ builds, longer campaigns, extra sanitizers, and ARM or x86 hardware diversity, the desktop client does more per machine. It runs the same protocol and reports to the same coordinator.

Turn on rewards

Contributing is free and anonymous. To collect rewards, connect a wallet on Robinhood Chain and lock a small operator stake. New operators can receive delegated starter stake, so you can become reward-eligible without buying anything first. See Staking.
