Compare

share-env vs every other option.

A honest, feature-by-feature comparison of every way developers currently share .env files — from the popular to the dangerous.

What is the safest way to share a .env file?

The safest method is to use an end-to-end encrypted, burn-after-reading tool that never transmits the decryption key to any server. share-env does this using AES-256-GCM, where the relay only stores ciphertext and the payload self-destructs after one pull — making it impossible to intercept after the fact.

Feature Matrix

How share-env compares.

Green = secure/available. Yellow = partial/limited. Red = not available/insecure.

Feature	share-env	Slack DM	Email	GPG file	1Password Teams	HashiCorp Vault
End-to-end encrypted	AES-256-GCM	No	No	Yes (manual)	Yes	Yes
Decryption key leaves your machine	Never	Yes (plaintext)	Yes (plaintext)	Key shared separately	Server holds it	Server holds it
Burn-after-reading	Yes (1 pull)	No (permanent)	No (permanent)	No	No	No
Auto-expiry TTL	10 min	Never	Never	No	Configurable	Configurable

Why not the others?

The hidden dangers of each alternative.

Why not Slack / Discord?

Messages stored permanently in Slack logs
Searchable by workspace admins and future employees
Exposed in any workspace data breach
No expiry — sits in history indefinitely
Bots and integrations may read the channel

Why not Email?

Sent in plaintext unless explicitly encrypted
Stored on mail server, potentially forever
Email threads can be forwarded accidentally
No expiry or burn-after-reading
Phishing attacks can intercept emails

Why not GPG?

Complex key management and key exchange
Sharing the passphrase has the same security problem
No burn-after-reading — file can be shared further
Error-prone for non-technical teammates
No git guardrail or merge conflict handling

Why not 1Password Teams / Vault?

Server holds the decryption key — not zero-knowledge
Account required for every team member
Monthly cost per user seat
Overhead for one-off dev-to-dev sharing
Not designed for CLI / terminal workflows

The better way

Stop sharing .env files the dangerous way.

share-env takes 10 seconds and is genuinely secure.
