Show HN: BuildBudget – GH Actions cost analyzer (found a $20k/month CI pipeline)

I built BuildBudget (https://buildbudget.dev) to help teams understand and optimize their GitHub Actions costs. You can try it without signing up at https://buildbudget.dev/demo, where I analyze CI/CD costs from top GitHub organizations.

While developing it, I discovered something interesting: React Native's test workflow costs $20k/month, making it the most expensive workflow among the top 10 GitHub orgs. The analysis is available at https://buildbudget.dev/blog/test_all_workflow/

What makes BuildBudget different: - Focuses on cost visualization - Specially useful for self-hosted runners users - Shows cost per job, not just per workflow - Makes minute-based billing impact visible - Helps identify matrix builds cost impact - Allows custom per-minute costs for different runner types

How it works: 1. Installs as a GitHub App 2. Receives workflow events via webhooks 3. Analyzes costs using GitHub's billing rules 4. Shows costs breakdowns and trends

Currently in beta, working on: - Automated cost optimization PRs - Cost simulations with different providers - More granular cost analysis

The demo is fully functional - no signup needed. For your own repos, installation takes <1 minute.
