ARCA vs 1Password

ARCA is built for processes and agents: arca agent, arca inject, and arca ssh on a vault file you own. 1Password is a hosted vault for human fill. ARCA has no account and no vendor blast radius.

Verdict

A local credential broker for agents and inject for scripts, not a hosted vault for human fill.

Feature comparison

  • Built for: ARCA — Humans and local AI agents. 1Password — Human fill in apps and browsers
  • Agent secret access: ARCA — arca agent: dummy env, real token on the wire. 1Password — Copy, paste, or a cloud automation add-on
  • Account and sync host: ARCA — None. 1Password — Required
  • Breach blast radius: ARCA — Your file only. 1Password — The vendor user base
  • Vault format: ARCA — Open spec + AGPL source. 1Password — Proprietary
  • License: ARCA — Free vault. $0 forever. Pro $99 once. 1Password — Subscription
  • Moving off 1Password: ARCA — Native .1pux import (Pro). 1Password — Export, then leave the account

Agents never hold the key.

Pasting a key into chat hands the agent the secret itself. Wrap Claude Code, Cursor, or Copilot with arca agent: dummy tokens in the process, real fields attached on the wire. arca inject still exists for scripts that should see env. ssh list, remove, and flush of still-served keys stay free.

No account, no vendor radius.

ARCA does not run a sync service or an identity system. Secrets live in one portable encrypted file. Named inner vaults (Pro) keep work, personal, and client sets inside that same envelope. Sync the file yourself, or nowhere. A breach at a password-manager vendor cannot include your ARCA vault.

Open core, engineered deniability.

The vault format, codec, and cryptography are published as arca-core under AGPL-3.0. A duress password opens a fully functional decoy vault. Shamir 3-of-5 recovery is paper cards you hold. Touch ID and Windows Hello unlock locally; they are not a network path.

Bring the 1Password export with you.

Pro imports 1Password .1pux archives into the local vault, distinct from env import. After that, named environments and inject are how tools receive secrets — not a second cloud account.

FAQ

  • What is a 1Password alternative for AI coding agents? ARCA. Wrap Cursor, Claude Code, or Copilot with arca agent so they never hold the token. Dummy env, real secret on the wire. There is no 1Password account.
  • Can I replace 1Password with ARCA for developer secrets? Yes for API keys, env sets, and SSH keys that tools on your machine need. Import a .1pux archive (Pro), keep named environments on one Env item, and inject the branch you want. The vault file is yours.
  • Does ARCA sync like 1Password? ARCA has no sync host. One encrypted file holds the vault. You may copy that file with whatever tool you already trust, or keep it on one machine. Named inner vaults share the same file.
  • How do I move from 1Password to ARCA? Export a .1pux archive and import it in ARCA Pro. Env import from dotenv files is a separate Pro path. Then wrap agents with arca agent instead of pasting keys.
  • Is ARCA a subscription password manager? No. Free vault. $0 forever. Unlock, search, store, CLI CRUD, and Shamir recovery. Pro is $99 once for inject, env import, agent wrap / start, and ssh add. Infisical/Conjur self-host is a server you run. ARCA Free is a local vault file with no server. Agent wrap is Pro.
