📋 Why Env Sync?
- 👋 Onboarding — New team members get a complete
.env.example. No more "what env vars do I need?" Slack messages. - 🚀 Deploy safety — Never deploy without a required environment variable again.
- 🌐 Multi-language — Works across your polyglot codebase — Node, Python, Go, Rust, and more.
- 🔒 Privacy-first — All scanning happens locally in your editor. No data leaves your machine.
