Kalligator is a bug bounty platform. You find a security flaw in a program, you submit a report, and an AI triage agent checks it. The agent tries to reproduce the flaw, checks the scope, and asks you a question when it needs more information. The Kalligator team makes the final decision and approves the reward. You can do all of this on the website. You can also let your own agent do it through the Kalligator API.
Test only the assets that a program puts in scope. Obey the program rules. Read Rules of engagement before you start.
