I built Decision Guardian after watching teams repeatedly debate decisions that were already settled.
At my last job, we chose Postgres over MongoDB for ACID compliance. 18 months later, a new engineer opened a PR to switch to MongoDB. The team spent 3 months re-evaluating before someone remembered.
Decision Guardian prevents this:
- Document decisions in markdown (why you chose X over Y)
- GitHub Action comments on PRs when decision-protected code changes
- Free, open source, MIT licensed
