Doppler alternatives that work offline, compared

If you want secrets that work with no account and no network, the choice is between a local vault and encrypted files. A local vault (Keyfold, KeePassXC, pass) keeps keys in one encrypted file on your computer. Encrypted files (dotenvx or SOPS) keep ciphertext next to your code and a private key on your machine. Both can start your app with the keys set, as doppler run does.

Before you switch, know that Doppler isn't purely online. Its CLI keeps an encrypted snapshot of each config you run and can use it with no connection. If your only problem is a flaky train connection, that may be enough. I build Keyfold, one of the options below, so read this with that in mind. Every fact about another tool comes from its own pages, checked on 20 October 2026.

Does Doppler work offline?

Partly. Doppler's fallback file docs say that "when using the doppler run command, the CLI automatically creates a fallback file containing an encrypted snapshot of the current secrets." According to its high availability page, the snapshots live in $HOME/.doppler/fallback, and if the CLI can't reach Doppler "after a timeout period (typically, 50-60 seconds), it will automatically fall back to using the snapshot file."

You can also skip the wait and read only the snapshot:

Terminal

$ doppler run --fallback-only -- npm start

The limits follow from what a snapshot is. It holds only the configs you ran while online, and by default it can only be decrypted with the same Doppler token that created it. New and changed secrets are made in Doppler, through its dashboard or doppler secrets set. And you still need a Doppler account to get the first snapshot.

So "offline" means two different things. If you mean "keeps working when the Wi-Fi drops", Doppler's fallback covers it. If you mean "no account, no third party, nothing leaves my computer", you need one of the options below.

What do you give up by leaving Doppler?

Doppler is built for teams that ship to several platforms, and for that job it's better than anything on this page. From its pricing page, checked today:

Team access. The free Developer plan covers 3 users, then $8 a month per extra user. The Team plan ($21 a month per user) adds role-based access, change requests and 90 days of activity logs.
Syncs to other platforms. The Developer plan includes 5 config syncs to hosting and CI services; Team includes 100.
Automatic secret rotation on the Team plan, and dynamic secrets on Enterprise.
An MCP server. Doppler's MCP docs list "Read secret values and download configs" among its tools, with a read-only mode that removes the write tools.

None of the offline tools below syncs secrets into Vercel, AWS or GitHub Actions for you. If you need that, keep Doppler for production and CI, and use something local for your laptop. The two work side by side.

Which offline tools can replace Doppler?

Here they are side by side. "Runs a command" means a built-in equivalent of doppler run:

Tool	Account	Offline	Runs a command with keys	Team sharing	Cost
Doppler, with its fallback	Yes	After one online run	`doppler run -- npm start`	Yes	Free for 3 users
Keyfold	No	Yes	`keyfold run -p acme-api -e development -- npm start`	No sync yet	One-time; see pricing
dotenvx	No	Yes	`dotenvx run -f .env.production -- npm start`	Through git	Free, open source
SOPS with age	No	Yes	`sops exec-env secrets.enc.env 'npm start'`	Through git	Free, open source
KeePassXC	No	Yes	No; script `keepassxc-cli`	Share the file	Free, open source
pass	No	Yes	No; script `pass`	Through git	Free, open source
macOS Keychain	No	Yes	No; script `security`	No	Built in

A comparison of Doppler, encrypted files with dotenvx or SOPS, and Keyfold: account, network, environments, running commands, team sharing, agent approvals and rotation — Offline tools trade team features for no account and no network.

A local vault: Keyfold

Keyfold is the closest match to how Doppler organises things. A Doppler project becomes a Keyfold project, and each config (dev, stg, prd) becomes an environment. keyfold run -p acme-api -e development -- npm start starts your command with that environment's keys set, the way doppler run does. The vault is one encrypted file on your computer, and the app makes no network connection except an update check on the Mac that it asks you about first.

The difference from everything else on this page is AI agents. Keyfold's CLI and MCP server only get keys after you approve the request in the app, and no MCP tool returns a secret value. An agent can run your tests with keys injected; it can't ask for a key and read it.

What it doesn't do: there's no team sharing and no sync between computers yet (folder sync is on the roadmap), no rotation integrations, and no syncs to hosting platforms. The Mac app is out now; the Windows app is coming through the Microsoft Store.

Encrypted files in the repo: dotenvx or SOPS

These keep secrets in your repository, encrypted, which suits teams that already share everything through git.

dotenvx encrypts the values in a .env file with dotenvx encrypt. The public key goes in the file, the private key goes into a .env.keys file, and the encrypted .env is safe to commit. dotenvx run -f .env.production -- node index.js decrypts at start-up and injects the values. It's open source under the BSD 3-Clause licence.

SOPS encrypts YAML, JSON, ENV and INI files with age, PGP or a cloud key service. With age, the private key lives in a keys.txt file; on a Mac that's ~/Library/Application Support/sops/age/keys.txt unless you set SOPS_AGE_KEY_FILE. Its exec-env command runs a program with the decrypted values in its environment, "never written to disk". SOPS is a CNCF project under the Mozilla Public License 2.0.

A password manager file: KeePassXC or pass

KeePassXC is free, open source (GPLv3), and stores passwords "in an offline, encrypted file". Its command line, keepassxc-cli, can show or copy an entry, but it has no command that starts a program with keys set, so you write that part yourself. pass stores each secret as a GPG-encrypted file in ~/.password-store and can track changes with git. Both are solid for a handful of keys; neither has environments or a .env workflow.

The macOS Keychain

Built in, encrypted and offline. security find-generic-password -w reads a key in a script. It works well for a few keys and gets awkward with many projects and environments; where to store API keys on a Mac covers it in detail.

Your own server: self-hosted Infisical

If what you want is Doppler's model without a third party, rather than no server at all, Infisical can be self-hosted: "This keeps your data on your own infrastructure and network." It's still a server to run and back up, so it's a team choice more than a laptop one.

How do I move my secrets from Doppler to a local vault?

One config at a time. In a project folder where doppler setup already points at the config, download it as a .env file. Doppler's own docs "strongly recommend against downloading secrets in plain text to the file system", so delete the file as soon as it's imported:

Terminal

$ doppler secrets download --no-file --format env > dev.env
$ keyfold import -p acme-api -e development -f dev.env
$ rm dev.env
$ keyfold run -p acme-api -e development -- npm start

Keyfold asks you to approve the import in the app, and creates the project and environment if they don't exist. The same file works for the other tools: dotenvx encrypt -f dev.env encrypts it in place, and SOPS can encrypt it into a new file.

Repeat for each config (stg, prd). When nothing runs through Doppler any more, doppler logout logs the CLI out.

Five steps to move one Doppler config: download as .env, import it, delete the file, run with keys, log out of Doppler — The plain file should exist for seconds, not days.

Which one should you pick?

You work alone, on one or two computers, and AI agents run your commands: a local vault such as Keyfold. Projects and environments map one to one, and agent requests wait for you.
You're a small team that shares everything through git: dotenvx or SOPS. Encrypted files go wherever the code goes, and the private key is the only thing you hand over.
You have five keys and a terminal: the Keychain, KeePassXC or pass.
You need syncs to hosting platforms, rotation or audit logs: stay on Doppler, at least for production.

The comparison table on the home page shows how Keyfold lines up against 1Password, Bitwarden, KeePassXC and plain .env files. For the risks of plain files in general, see how .env files leak.

FAQ

Is there an offline mode in Doppler?

Yes, for reading. doppler run saves an encrypted snapshot of each config, and doppler run --fallback-only uses only that snapshot. Adding or changing secrets still goes through Doppler.

What's the closest free alternative to Doppler?

For a team that works through git, dotenvx or SOPS: both are free, open source and inject secrets into a command. For one person, KeePassXC is free but has no command that runs a program with keys set.

Can I use Doppler and a local vault together?

Yes. A common split is Doppler for production and CI, where its syncs and audit logs help, and a local vault for development keys on your laptop.

Do any offline tools sync between computers?

KeePassXC and SOPS files can sit in a folder you already sync, and pass and dotenvx files travel through git. Keyfold has no built-in sync yet; people keep the vault file in a synced folder, and folder sync with conflict handling is on the roadmap.

Does Keyfold work with AI coding agents?

Yes. Its MCP server lets Cursor, Claude Code and other clients run commands with keys injected or write a .env file you approved. Every request waits for your approval in the app, and no tool returns a secret value.
