Which one, for what

Grok Bot E

Best for A person or team already paying for Cursor or SuperGrok who wants named assistants that keep working on a cloud computer, with routines and Slack or X entry points, and who will write approval rules.

Ahead on

  • Reliability, 40 against 32
  • Schema & documentation, 40 against 33
  • Security & auth, 68 against 34
  • Maintenance & community, 20 against 15
  • Transparency & trust, 66 against 60

Watch for

All of one user's Bots share one cloud computer, with its files, browser sessions and command-line credentials. The docs say separate Bots are not a security boundary

Leon E

Best for A developer who wants a self-hosted assistant with memory, computer use and a local model, and who will read the source.

Ahead on

  • Agent ergonomics, 57 against 50
  • Payments & pricing, 60 against 25

Also in its favour

  • No key needed to call it
  • Free to start without a card
  • Open source

Watch for

No tagged release of the core since 1.0.0-beta.8 on 1 May 2023. The 2.0 Developer Preview is installed by cloning the develop branch

Verdicts

Grok Bot

Connector tokens stay on Cursor's backend and each user gets a separate microVM, with approvals, drafts and a review model before risky actions. All of a user's Bots share one computer and its sign-ins, the review model skips memory writes, and the status page shows seven major Grok Bot incidents since 3 September 2026.

Leon

Connected-app credentials are encrypted per profile and the Gmail connection is read-only. The 2.0 Developer Preview has no tagged release, runs tools and a 30-minute proactive pulse with no approval step, listens on every network interface with client authentication off, and sends telemetry by default.

Before you call either

Grok Bot

  1. State in each request what the Bot may change and where it must stop. Which actions pause for approval depends on the tool, the risk and the owner's Auto-review rules
  2. Add narrow Ask first rules for sending, publishing, purchasing and deleting. Ask first wins over Allow automatically when both match
  3. Treat any sign-in or file on the cloud computer as available to every Bot on the account. Give a workload its own Cursor user when it needs separate credentials
  4. Run Test run with safe inputs. A test run performs real work and can call connected tools
  5. To remove access, pause routines, sign out of sites on the computer, uninstall connectors and revoke them at the source service. Deleting the Bot is not enough

Leon

  1. Clone the develop branch for 2.0. npm install --global @leon-ai/cli and docs.getleon.ai install and describe the legacy 1.0 betas
  2. Set client_interface.auth.enabled: true and a LEON_PROFILE_TOKEN before the machine joins a shared network. The server binds 0.0.0.0
  3. Set telemetry_enabled: false and runtime.pulse_enabled: false in the profile config.yml for an unattended or private run
  4. Use availability.tools.allowed to limit tools. Shell, file writes, computer use and browser control are otherwise available to the agent with no approval prompt
  5. Back up LEON_CONNECTIONS_ENCRYPTION_KEY from the profile .env. Without it the stored connections cannot be read
