Buttercup is an AI-powered system that automatically finds and fixes security bugs in open-source software by running smart tests (fuzzing) and then creating patches to fix vulnerabilities. It works mainly on Linux with at least 8 CPU cores, 16 GB RAM, and 100 GB disk space, using AI models from providers like OpenAI or Anthropic. You can easily set it up on your computer, monitor its progress through a web interface, and control costs by limiting AI usage. This helps you improve software security efficiently without manual code review, saving time and reducing risks from software bugs.
