Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Payments & pricing OpenMausBot +50

Conductor 0

No new sign-ups since 4 November, free users can't upgrade, and no price is shown. No protocol, no published price, no open free tier, no onboarding (0).

OpenMausBot 50

No payment protocol (0). MausBot Cloud, the hosted option, is priced by plan on a public page ($15, $49 and $99 a month, Team $169 and Business $599, or Business self-hosted $299 a month billed yearly, re-read on 2 November), with extra computer-hours at $0.05 each, so plan pricing (10). The app is free with no card or account (20). npx openmausbot installs and starts it with no signup (20).

Reliability OpenMausBot +35

Conductor 25

Read as local software that is winding down. Installed from Conductor's own download, which stopped taking new users on 4 November 2026 (10). Closed source, so no public CI or issue tracker (0, 0). A dated changelog, newest 0.93.0 on 4 November (15). Version 0.93 (0). 10 + 0 + 0 + 15 + 0 = 25.

OpenMausBot 60

Read as local software. Official npm package openmausbot (Node.js 24 or newer) and signed, notarised macOS builds, a Windows installer and Ubuntu 24.04 packages, with supported platforms and a capability table in the README (20). 2,075 test files and a CI workflow on main. Of the last 23 finished CI runs on main on 30 October 2026, 10 passed, 3 failed and 10 were cancelled by newer pushes in a serialised queue (20). 365 open issues against about 3,940 issues and pull requests filed since 11 August, so most are closed, but the 25 newest open issues include several bug reports from 29 and 30 October with no reply yet (15). Release notes for every version in New, Easier and Fixed sections, but new capabilities ship in 0.1.x patch versions and no release marks breaking changes (5). Version 0.1.134, and the README calls the project early (0).

Schema & documentation OpenMausBot +30

Conductor 60

Harness reading. Docs for workspaces, review and merge, a Conductor API reference page linked from the docs (not read), and security and permissions pages (60).

OpenMausBot 90

The MCP server's 20 tools each have a JSON Schema input with additionalProperties: false and required fields marked. No OpenAPI for the local HTTP API (25). Markdown docs in the repository, and the docs app's source serves llms.txt, llms-full.txt and Markdown routes. docs.openmausbot.com disallows every crawler, so the live llms.txt was not read (10). Descriptions state purpose and limits, such as that update_bot_profile cannot alter permissions, that send_bot_message may make the bot use external tools and that edit_bot_message is refused while a thread works, and the server instructions say to read before mutating. Few say when not to use a tool (15). Integer limits with minimum and maximum, an enum on scope, a pattern on send_id and oneOf shapes for responders (13). JSON configuration examples for each install path, the wait statuses and job states, CLI exit codes and a { ok, error, hint, exitCode } failure shape (12). MCP server version 1.1.0, release notes per version and a changelog page in the docs (15).

Agent ergonomics OpenMausBot +22

Conductor 55

Harness reading. Each task gets a workspace, branch, terminal and diff, with pull requests and merges from the app, and an API for integrations; not re-read in detail (55).

OpenMausBot 77

20 tools, inside the 11 to 30 band, with annotations that separate reads from writes but no toolsets or read-only mode to load. Transcript reads are bounded and never return screenshot pixels (17). limit up to 200 messages, search capped at 100 hits, task_id and scope filters, and since_ms and after_version to keep watching a job (17). wait_for_conversation reports settled, needs-user, failed, stalled or timed-out with a redacted transcript tail, and the CLI's exit codes separate a pending approval from a timeout. We did not read every MCP error path (15). send_id makes a repeated send return the first receipt, wait is held by the server rather than polled, and every tool carries readOnlyHint, destructiveHint, idempotentHint and openWorldHint (20). Few required parameters and defaults for task, limit and timeout. The server answers only while the app or openmausbot serve runs, mutating tools need a paired token in packaged builds, and there is no client SDK beyond the CLI (8).

Maintenance & community OpenMausBot +16

Conductor 58

0.93.0 on 4 November 2026 (30). Several dated releases in 90 days, per the changelog index (20). Discord, a subreddit and email for support (8). Closed app, no package or CI to read (0). 30 + 20 + 8 + 0 + 0 = 58. The local app gets new models and critical fixes only until early 2027.

OpenMausBot 74

v0.1.137 on 1 November 2026, after v0.1.135 on 31 October and v0.1.136 on 1 November (30). 128 desktop versions from 11 August to 30 October 2026, and three more since (20). The maintainer has 4,221 commits and the contributor list returns at least 100 accounts. 587 issues and pull requests were open from about 3,940 filed on 30 October, when we could only sample the newest open issues, nearly all from the last two days and mostly unanswered so far (per the 30 October check; github.com refuses our requests on 2 November) (16). Not in the official MCP registry, which returns nothing for mausbot (0). CI on main runs on every push with most finished runs passing, npm provenance and an SBOM for the bundled Cua runtime (per the 30 October check) (8). 30+20+16+0+8 = 74.

Security & auth OpenMausBot +14

Conductor 45

Closed app. Telemetry and data handling weren't read beyond the transition notice (10 of 30). A security and permissions page (10 of 20). No prompt-injection guidance found (5). No audit log found (5). SOC 2 Type II report at trust.conductor.build (15 of 20). 10 + 10 + 5 + 5 + 15 = 45.

OpenMausBot 59

Harness reading of the framework checklist, as for the other harnesses. 30 for what leaves the machine by default, 20 for approvals and sandboxing, 15 for prompt-injection posture, 15 for audit and 20 for the security programme. The harness binds to loopback and keys stay in ~/.openmausbot, but PostHog usage analytics are on until switched off, with a daily snapshot of what is set up, and the CLI guide says API keys are saved in plaintext with mode 0600 (18). Approval cards for provider permission requests, a narrow Always allow, isolated Local VMs and cloud computers, own-computer control off by default, and an MCP server that cannot approve, delete or touch credentials. New bots start at Full access, bot changes to skills, profiles and team setup apply without approval, and new bots keep every connected-app tool until grants are assigned (10). The docs say web page instructions never authorise credential use and that one-time codes go only to the site that sent them, and imported bots arrive with no grants, but bots read one-time codes from connected email without asking again (9). Per-thread NDJSON event logs, an Inspector, a decision log for connected-app grants and Undo lines for bot changes (12). SECURITY.md with an email, GitHub private vulnerability reporting enabled and scope notes that name one open risk. No published advisories, security.txt or bug bounty. npm releases use trusted publishing with provenance, and the Windows installer is unsigned (10).

Verdicts

Conductor

Conductor ran parallel coding agents on the Mac, and Meta is acquiring it. It has taken no new users since 4 November 2026, Cloud turns read-only on 13 November and shuts down on 20 November, and the local app winds down in early 2027, when all user data is deleted.

OpenMausBot

A bounded 20-tool MCP server with typed schemas, annotations and idempotent sends, and a headless CLI with JSON output and exit codes, let another agent hand work to a bot team and wait on it. New bots start at Full access, so provider permission requests pass without a card, and usage analytics stay on until switched off.

Before you call either

Conductor

  1. Export your data from Settings, Account, Export data before 20 November 2026
  2. Move Cloud workspaces to your Mac with Transfer to local before 13 November
  3. Plan a move off the local app before early 2027; see the agent-harnesses category for alternatives

OpenMausBot

  1. Ask the owner for a pairing code from Settings > Phone, exchange it at POST /api/auth/pair, and set OPENMAUSBOT_TOKEN with an explicit OMB_PORT
  2. Pass a send_id with every send_bot_message and send_channel_message, so a retry returns the first receipt
  3. Use wait_for_conversation instead of polling, and on needs-user stop and tell the owner a card is waiting
  4. Check a bot's access level with the owner before sending work. New bots run at Full access unless defaults were changed
  5. Ask the owner to switch off Settings > General > Usage analytics if nothing beyond model calls should leave the machine
