Show HN: VS Code extension for dotenv-diff
chrilleweb Sunday, February 22, 2026
I recently published a VS Code extension for dotenv-diff, this is quite simpler than the dotenv-diff npm package.
The problem: you don't always want to install a dependency.
The solution: a VS Code extension so you don't have to install a dependency — it just works out of the box.
This version of dotenv-diff is simpler, it simply does:
- Warn when you have an environment variable that is used in the code but not defined in .env - Warn when you have a .env variable that is not used anywhere in the code
Feedback or suggestions are very welcome!
Summary
This open-source Visual Studio Code extension allows users to easily compare and manage environment variables across different development environments, helping to ensure consistency and reduce errors when working with multiple configuration files.
