Description
It works on my machine" is still the most common deployment bug I kept running into the same stupid deployment issue. Everything works locally. Tests pass. I deploy. Production crashes. After digging through logs for an hour the problem ends up being something simple like: • a missing environment variable • something added to .env.example but not to .env • a config mismatch between environments The most common one for me was forgetting to add a variable locally after adding it to .env.example. So I built a small tool to catch this instantly. It compares .env and .env.example and tells you if something required is missing before deployment. Example output: deploycheck running...Missing variables: - DATABASE_URL - REDIS_URLFix the issues above before deployment. The idea is basically a spell checker for backend configuration mistakes. Instead of finding out after deploy, it catches the issue while you're still working. Right now it can: • detect missing environment variables • run locally as a CLI • run in CI as a check before deployment I’m trying to figure out if this is actually useful outside my own workflow. Curious if others run into this problem as often as I do.

Could you build this?
Yes Safelaunch is a pre-deployment CLI or CI/CD script that checks environment variables, schema compatibility, and config files against production requirements.

Competitors mentioned: Pydantic Config class, custom environment/config parsing
Concerns raised: comparing .env to .env.example is brittle, feature is trivial to implement in-house

Same idea, different domain
Nobody's really built a compliance & governance tool for Media & entertainment yet.
