About DevCost Tools
12 free developer cost calculators. One mission — answer how much something costs before your billing cycle ends.
Why We Built This
GitHub Actions billing surprised us. macOS runners cost 10x more than Ubuntu — most teams only find out on their first unexpected bill. Firestore charges per document read — one poorly written query turns a free app into a $200/month problem. AWS CodeBuild EC2 bills full minutes even for 30-second builds while Lambda bills per second.
Every major developer platform has pricing that is buried in documentation, hidden behind dashboards, or impossible to estimate without running actual workloads. We wanted calculators that answer the question upfront — before committing to a platform, before the billing cycle ends.
So we built 12 of them. All free. All 2026 pricing. No signup. Runs entirely in your browser.

How Each Calculator Works
Bidirectional sliders and number inputs for the metrics each platform charges for — MAU, bandwidth, build minutes, reads, writes, invocations.
All calculations use official 2026 pricing data and run entirely in JavaScript — no server, no account, no latency.
Comparison tools show which platform is cheaper for your exact workload. Scale tables show costs at 6 different usage levels.
Every tool includes copy-paste optimization snippets — switch to ARM, add dependency caching, use path filters, switch runners.
