## Project history and usage

subfinder is ProjectDiscovery's passive subdomain-enumeration CLI. The official docs describe it as a tool that finds valid subdomains using passive online sources, with a modular architecture optimized for speed, stealth, and integration into penetration-testing and bug-bounty workflows.

### Project history

Official Git tags in the ProjectDiscovery repository show public releases beginning in 2018, with v2-era tags appearing by late 2019 and continued v2 releases through 2026. The README frames the project as a single-purpose tool: passive subdomain enumeration that respects source licenses and usage restrictions.

### Adoption history

The install docs document Go, Homebrew, Docker, GitHub source builds, and downloadable binaries. The input package-manager facts additionally list Homebrew, DNF, Nix, and zypper, showing the tool's spread across security-tool packaging channels.

### How it is used

Typical usage is `subfinder -d example.com` or feeding domain lists, choosing passive sources, writing JSONL or text output, and using stdin/stdout in larger reconnaissance pipelines. Its docs also emphasize post-install provider configuration because many passive sources require API keys.

### Why package nerds care

subfinder matters in package-manager culture because ProjectDiscovery tools are often installed as a suite of composable Go CLIs. Packagers care about its static-binary-friendly Go distribution, Docker image, Homebrew formula, config and credential paths, and compatibility with automation-heavy security workflows.

### Timeline

- 2018-05-01: Earliest official repository tags include v0.1 and v0.1.1.
- 2018-06-26: Official repository tag 1.0 created.
- 2019-12-05: Official repository tag v2.0 created.
- 2026-04-25: Official repository tag v2.14.0 created.

### Related projects

- The official docs place subfinder within ProjectDiscovery's open-source security-tool family, alongside tools such as httpx, nuclei, naabu, katana, notify, uncover, and the ProjectDiscovery Tool Manager.
