Frequently asked questions

Why can't I just email my .env file?
.env files typically contain EVERY secret in your stack — database, API keys, Stripe. One email leak = complete application compromise.
How do I onboard a new developer securely?
Generate a CipherEdge link for the .env file, set 1-view TTL, send via any channel. The developer sees it once and it's gone.
What's the maximum .env file size?
Free tier supports up to 10MB — enough for any .env file. Pro tier supports up to 250MB for larger config bundles.
Can I share multiple env files at once?
Create a .zip of your env files and attach that — the entire archive encrypts as a single payload.
