Open Source

NULL TOOLS is built on a number of open-source libraries. This list covers the ones actually shipped in the code your browser runs (not build-only tooling like Vite, TypeScript, or Tailwind's compiler, which never reach your browser as their own code) — checked against each app's real dependency tree and, where it mattered, against the actual deployed code itself rather than assumed from a dependency list alone. We're grateful to the people who build and maintain these.

Not open source, but worth disclosing

Cloudflare Turnstile (bot-protection on our forms) is a proprietary third-party service, not an open-source library — it's already covered in our Privacy Policy's third-parties section rather than here.
