SecDim
Find a flaw in an app, then patch the code and push the fix
SecDim is a security wargame for developers. Each challenge is a small app based on a real incident: you first confirm the flaw, then fix the code and push your patch with Git, and the platform's tests check whether your fix works.

About SecDim
It trains secure coding and patching in languages such as Python and PHP, as well as cloud topics. It suits developers who want to practise fixing code rather than only finding bugs.
It runs through Git and the browser. A quick challenge works without signing up. The free Community plan includes public challenges with 10 attempts a month, and a Professional plan adds the full catalogue.
