filiksyos/gitsimilar — reverse-engineered prompt

I want a web app where I can enter a GitHub repository URL or its owner/repo name and it will find other public GitHub repos that probably use similar tech or services, based on the environment variables in their .env.example or similar files. It should analyze the env file to figure out which variables are most likely tied to shared infrastructure or platforms, and then search GitHub for other repos with those variables in their own env files, showing me the most popular matches and their descriptions. If you need to, you can use OpenRouter for picking the most relevant variable names and GitHub’s API for code searching. The app should be easy to run locally in development, and I’ll provide the necessary API keys in the .env file. If you hit a snag with files or authentication, just explain what’s missing. Look up any docs you need online.
