CrowdSec
A self-hosted Security & Privacy app you can run on your own server.

Development happens in the open on GitHub; the repository has collected 14.8K stars so far. Repository activity was last recorded on Sep 11, 2026, and the project is classed as actively maintained in our snapshot.
Before you switch
Security tools deserve extra scrutiny — you are trusting them with sensitive data. Prefer projects with published audits, two-factor or SSO support, and clear documentation of their threat model. Keep them updated; an unpatched security tool is worse than none.
Like every project listed on SelfHosted, CrowdSec is developed in the open — you can read the code, follow development, and even contribute. Check the system requirements and the project’s own documentation linked on this page before installing.
