Also in its favour: - No key needed to call it - Free to start without a card Watch for: No API, MCP server or documented command an outside agent can call ### IronClaw (B) Good for: One technical owner who wants a self-hosted assistant over Gmail, Calendar, Slack and Telegram with credentials kept out of the model's reach. Ahead on: - Schema & documentation, 74 against 15 - Agent ergonomics, 69 against 9 - Security & auth, 66 against 49 - Maintenance & community, 74 against 51 - Transparency & trust, 75 against 56 Watch for: Global auto-approve defaults to on in the 1.4.1 source, so tools marked ask (send, trash, delete) run without a prompt. Only financial, approval and budget effects always ask ## Score by category | Category | Weight | Atticus | IronClaw | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 68 | 67 | Atticus +1 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 15 | 74 | IronClaw +59 | | Agent ergonomics | 13% (16.2 this run) | 9 | 69 | IronClaw +60 | | Security & auth | 14% (17.5 this run) | 49 | 66 | IronClaw +17 | | Payments & pricing | 10% (12.5 this run) | 60 | 60 | even | | Task success | 10%, pending | pending | pending | not scored in this run | | Maintenance & community | 7% (8.8 this run) | 51 | 74 | IronClaw +23 | | Transparency & trust | 7% (8.8 this run) | 56 | 75 | IronClaw +19 | | Negative events | ≤15 | 0 | -2 | | | **Total** | | **42.9 · E** | **66.7 · B** | | ## Facts side by side | Fact | Atticus | IronClaw | | --- | --- | --- | | Kind | Platform | Agent harness | | Vendor | SaarthurR (Saarth Ranka) | NEAR AI | | Hosted endpoint | no (local only) | no (local only) | | Transports | | HTTP | | Auth | None | OAuth or key | | Pricing | Your plan | Freemium | | x402 | no | no | | Licence | MIT | MIT OR Apache-2.0 | | Read-only variant documented | no | no | | llms.txt | no | yes | | Last release | 2026-10-14 | 2026-09-29 | | Terms last updated | no document linked | no document linked | | Privacy policy last updated | no document linked | no date given | | Customer content may train models | | | | Terms restrict automated access | | | | Terms restrict benchmarking | | | | Terms or service can change without notice | | | | Arbitration or class-action waiver | | | | Popularity | 163 stars | 13k stars | ## Verdicts **Atticus.** Atticus runs a person's Mac by voice on their existing Claude or Devin plan, with a sandboxed safe mode and a local log of every command. It has no API, MCP server or documented command for another agent, it is five days old, and it rebuilds itself from the main branch every six hours by default. **IronClaw.** Credentials stay in an encrypted store and are injected at the host boundary, and extensions declare per-tool permissions, network targets and OAuth scopes. The global auto-approve setting defaults to on in the 1.4.1 source, so tools marked ask, such as `gmail.send_message`, run unprompted until the owner turns it off. ## Before you call either ### Atticus 1. Don't plan to call Atticus from another agent. It takes requests only from its own shortcut and typing box 2. If a user runs Atticus beside you, expect it to move windows and type into apps on the same Mac 3. Point a user who wants pinned versions to Settings > About & Updates to turn off self-update ### IronClaw 1. Open Settings and turn off global auto-approve, or set send and delete tools to ask each time, before connecting mail or chat accounts 2. Install with the release installer and run `ironclaw onboard`. 1.x does not migrate 0.29 data, so use a fresh home directory 3. Call `POST /api/v1/responses` with the bearer token from `~/.ironclaw/reborn/webui-token`. Keep under 30 requests in 60 seconds 4. Resolve approval and OAuth gates in the web interface. The Responses API fails the turn instead of surfacing them 5. Connect MCP servers over HTTP only. The stdio transport is rejected ## Questions ### Which is better for AI agents, Atticus or IronClaw?
