ChangeTrail – Open-source unified change timeline for incident response

I built this because every on-call incident starts with "what changed?"
and I'd spend 20 minutes jumping between Kubernetes, GitHub, and AWS
dashboards to figure it out.

ChangeTrail collects changes from all those sources and shows them on
one timeline. You can try it in 60 seconds:

git clone https://github.com/cvemula1/ChangeTrail.git && cd ChangeTrail && make up

It's Python/FastAPI + React, runs fully self-hosted with Docker Compose.
MIT licensed. Currently supports Kubernetes and GitHub, with ArgoCD and
Terraform collectors as good-first-issues for contributors.

Would love feedback on the approach and what sources to prioritize next.
