.env Example Generator
Paste your .env file and generate a matching .env.example with all values stripped or replaced by placeholders, safe to commit to version control.
🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.
Example shown — paste your own .env below to replace it.
How .env Example Generator works
- Paste your real .env file — parsing happens locally in your browser as you type, nothing is ever sent anywhere.
- Each line is classified: comments and blank lines are optionally kept for structure, and each KEY=VALUE pair is inspected by its key name.
- Sensitive-looking keys (containing SECRET, KEY, TOKEN, or PASSWORD) are stripped to a blank value; other keys get a generic placeholder that still hints at the expected format (a URL, an email, a port number).
- Copy the result straight into a new
.env.examplefile — safe to commit, since it documents which variables exist without exposing your actual values.
FAQ
Is it safe to paste real secrets (API keys, passwords) into this tool?
Yes in the sense that matters most: everything runs as local JavaScript in your own browser tab, so your .env contents are never sent over the network to us or anyone else. That said, treat any tool the same way you'd treat a text editor — close the tab when you're done and don't leave secrets sitting in a browser you don't control.
How does it decide which values to keep versus strip?
Plain booleans (true/false) and numbers are kept as-is if that option is checked, since they're rarely sensitive and often necessary for the example to be useful (a default pool size, a feature flag). Any key containing SECRET, KEY, TOKEN, or PASSWORD is stripped to a blank value; keys like URL, EMAIL, PORT, and HOST get a generic placeholder that still shows the expected shape.
Does it handle quoted values and comments correctly?
Yes — quoted values (single or double quotes) are unwrapped before the key is classified, comment lines (starting with #) and blank lines are optionally preserved for structure, and any line that doesn't match the KEY=VALUE pattern is passed through unchanged rather than dropped.

Blanking each value by hand is slow and easy to get wrong on a long file, and pasting secrets into an unfamiliar text tool is a real risk if it doesn't say plainly where your data goes. This generator strips values by key-name pattern in a page that runs entirely client-side.
