notenv

Encrypted secrets, no infrastructure, no plaintext on disk.

notenv replaces .env files: secrets are encrypted on your machine with age, kept as ciphertext in a local vault or on storage you already own (Backblaze B2, S3, Google Drive, SFTP, WebDAV, anything rclone speaks), and decrypted only into the environment of the command you run. Plaintext never touches disk.

Why

A .env file is plaintext: everything on your machine can read it, and sharing it means pasting it somewhere it will outlive. notenv removes the file instead of guarding it.

• You hold the key, not a provider. Secrets are age-encrypted locally; storage only ever sees ciphertext. There is no account to create, no SaaS to trust, no vendor that can read, lock, or lose your data.
• Storage you already have. A local folder, a home NAS, B2, S3, Drive, SFTP, WebDAV, dozens more. Move a vault from a folder to a cloud remote in one command when syncing starts to matter.
• Nothing on disk to leak. A test runner, a package postinstall script, or a coding agent in your checkout cannot read a secret that exists only inside the process you ran, only while it runs.
• Joining and leaving are one command. Onboard a teammate with a string sent over chat; their first run swaps it for a credential only they know. notenv key rm re-encrypts everything, so offboarding actually revokes, not just "please delete your copy."
• Nothing to operate. notenv setup is one passphrase and zero accounts. No server to stand up, patch, or pay for.

Not this if you want a platform: there is no web console or SSO, and access is scoped per vault, not per secret (everyone in a vault can read that vault). If a platform team already runs Vault, keep Vault.

Install

uv tool install notenv                                  # also: pipx install notenv, or pip
go install github.com/DvGils/notenv/cmd/notenv@latest   # with Go

Or download a prebuilt binary for Linux, macOS, or Windows (amd64 / arm64) from Releases and put notenv on your PATH. Releases are reproducible, signed with cosign (keyless), and carry SLSA build provenance; the installation guide shows how to verify a download.

Quick start

notenv setup                   # 1. set up this machine once (local vault by default)
cd my-project && notenv init   # 2. declare the project (writes notenv.toml, which you commit)
notenv import .env && rm .env  # 3. import existing secrets (or `notenv set KEY` one at a time)
notenv run -- npm run dev      # 4. run anything with the secrets injected

That is the whole loop. notenv is a process wrapper, so it works with any language that reads environment variables. On a new machine: git clone, then notenv setup with your escrowed passphrase, and you are ready. When syncing across machines starts to matter, notenv vault copy moves the same vault to a cloud remote in one command.

How it works

notenv run -- cmd
  |
  |-- fetch ciphertext   <- rclone <-  your B2 / S3 / Drive / ...
  |-- unlock the master key (from your passphrase; cached after first use)
  |-- decrypt secrets in memory
  |-- build the child environment from notenv.toml
  |-- exec cmd, stream its I/O, exit with its code
        nothing written to disk

A random master key encrypts every secret and never exists in plaintext at rest: a small header holds it wrapped under one or more key slots (a person's passphrase or a machine's age public key), the way LUKS and restic do it. The header is authenticated and version-pinned, so a party who can write your storage but holds no key cannot tamper with it or roll it back undetected. Full detail in Concepts.

For AI agents

A .env on disk eventually lands in a coding agent's context. notenv gives the agent a verb that separates using a credential from knowing it:

• notenv run -- cmd injects secrets into the child only; the value never appears in what the model reads, and captured output is masked.
• notenv list shows which secrets exist and what they are for, never their values.

For a scoped session, notenv handoff -- <agent> runs the agent against an ephemeral vault holding only one namespace, so it never holds the key to the rest of your vault. An installable agent skill (skills/notenv/) teaches it the commands. See the AI agents guide.

How it compares

dotenvx and op run both nail encrypted injection; the difference is the master. dotenvx keeps the encrypted file in your repo and leaves distributing and rotating the private key to you; 1Password is excellent but is a service that holds your secrets and that you depend on. SOPS + age give you the keys but leave storage and onboarding as homework. notenv is the one combination of all three: keys you hold, storage you already own, and onboarding built in, with nobody in the loop.

Security

At rest, anywhere, only age ciphertext exists; it is useless without your key, which lives in your password manager and never on the storage backend. The threat model covers what notenv defends, against whom, and the explicit non-goals. To report a vulnerability, see SECURITY.md.

Building from source

git clone https://github.com/DvGils/notenv
cd notenv
make build       # compile ./notenv
make test        # run the test suite
make install     # install into $(go env GOPATH)/bin

Releases are produced with GoReleaser; make snapshot builds the full set of release artifacts locally without publishing.

Status

Actively developed and being tested. See the roadmap for what works today, what is planned, and the non-goals.
