Env Manager
Manage .env files with secret masking, multi-environment comparison, missing variable detection, and usage search.
Features
Browse all .env files in your workspace with their variables organized in an Explorer sidebar panel.
Secret Masking
Values are hidden by default. Toggle masking with the eye icon to reveal or hide all values.
Multi-Environment Comparison
Compare any two .env files side-by-side using VS Code's built-in diff viewer. Quickly spot differences between .env.development and .env.production.
Missing Variable Detection
Automatically warns when variables defined in .env.example are missing from your .env files. Shows warnings both in the sidebar and as VS Code diagnostics.
Variable Usage Search
Right-click any variable and select "Find Variable Usage" to search your entire codebase for references. Supports:
process.env.KEY (Node.js)import.meta.env.KEY (Vite)os.environ["KEY"] (Python)ENV["KEY"] (Ruby)env::var("KEY") (Rust)System.getenv("KEY") (Java)
Hover Preview
Hover over process.env.API_KEY (or equivalent) in your code to see the current value from your .env file.
Generate .env.example
Automatically generate a .env.example file from your existing .env, stripping all values but keeping keys and comments.
Sort Variables
Sort all variables in a .env file alphabetically.
Add, Edit, Delete
Manage variables directly from the sidebar without opening the file.
