PD Open Source Tools

ProjectDiscovery produces a suite of open source tools tailored for offensive security: security engineers, bug bounty hunters, and red teamers. Our toolkit is structured around three distinct layers to optimize your security assessment and penetration testing processes. We also provide utilities and libraries as building blocks for an offensive security or bug bounty hunting program.

To learn about all of the tools, see our tools documentation or check out this video. You can also find the tools in our various GitHub repositories. A few of our most popular projects include:

  • nuclei: A fast and customizable vulnerability scanner based on simple YAML based DSL.
  • nuclei-templates: Community curated list of templates for the nuclei engine to find security vulnerabilities.
  • subfinder: A fast passive subdomain enumeration tool leveraging dozens of APIs.
  • httpx: A fast and multi-purpose HTTP toolkit that allows running multiple probes using the retryablehttp library.
  • cvemap: A CLI to Navigate the CVE jungle with ease.
  • katana: A next-generation crawling and spidering framework.
  • naabu: A fast port scanner written in go with a focus on reliability and simplicity.
