I got tired of guessing my cloud bills, so I built 12 free developer cost calculators (No login, No BS).

Hey everyone, I kept running into the same problem: trying to figure out exactly how much a CI/CD pipeline or a cloud service was going to cost before getting the actual bill at the end of the month. Comparing GitHub Actions vs GitLab CI, or trying to understand AWS Lambda vs EC2 costs, usually meant digging through endless pricing docs and doing the math manually. So, I built a solution: a suite of 12 free, privacy-first developer cost calculators. Here are a few of the tools included: GitHub Actions Cost Calculator: Paste your YAML workflow and instantly see the exact per-run and monthly costs across Ubuntu, Windows, and macOS runners. (Did you know macOS runners cost 10x more than Ubuntu?) CI/CD Cost Comparison: Compare GitHub Actions, GitLab CI, and CircleCI side-by-side to find the cheapest platform for your specific workflow. AWS Tools: Lambda vs EC2 calculators, comparing x86 vs ARM Graviton2 architecture (switching to ARM can save you 20% on Lambda). AI API Rate Limit Calculato
