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 Clawboo +35

Clawboo 60

No payment protocol (0). Read with the self-hosted rule. Free under MIT with nothing to buy (20). No card and no Clawboo account (20). One npx command installs and starts it with no sign-up (20). Model costs belong to the providers the owner connects.

HarnessRouter 25

Published rubric, for the hosted service. No machine payment protocol (0). Per-unit prices without a login, agent work per active minute and model calls at listed provider prices per million tokens (20). The Free plan needs no card, but it only configures agents, and running a task draws on card-funded credit, so 5 of 20. A person signs up in a browser and creates the key in the console (0). 25 in all. Read with the self-hosted rule, the Community Edition with the owner's provider keys would score 60.

Maintenance & community HarnessRouter +21

Clawboo 51

0.5.0 was published to npm on 21 October 2026 (30). Two releases in the 90 days to 1 November 2026, 0.4.0 on 28 September and 0.5.0, below the three the line asks for (0). github.com was unreachable, so replies to issues, pull requests and Discussions are unchecked. The CI file cites issue #140 as fixed (3). One public npm package, current, with no entry in the official MCP registry for its four servers (10). CI, CodeQL, weekly Dependabot and SLSA provenance on 0.4.0 and 0.5.0, with @composio/client pinned to an alpha (8).

HarnessRouter 72

Open-source reading of the repository behind the hosted service. Last tag v0.34.2 on 16 October 2026 (30). 202 tags between 15 August and 16 October (20). GitHub's issue pages and API refused this session, so open issues and reply times are unchecked. Pull requests from at least ten outside authors were merged in the 30 days to 17 October, by the git history (15 of 25). No official SDK and no MCP server to register (0). A tests workflow runs every suite on each pull request and push to main, with a release workflow and a Docker image, but whether the default branch passes is unchecked (7 of 10). 72 in all.

Reliability Clawboo +17

Clawboo 52

Read as local software. The official npm package clawboo states Node.js 22.12 or newer, and the README says macOS, Linux and Windows are supported (20). ci.yml runs lint, typecheck, Vitest and a real-concurrency suite on Linux and platform suites on Windows and macOS, and publish.yml reruns build, lint, typecheck, tests and a clean-install boot before it publishes. 0.5.0 carries provenance from that workflow on main, so its checks passed at that commit, but run results on main couldn't be read (15). github.com was unreachable, so open crash and regression issues are unchecked. A known-issues page lists 25 entries with a status each, three of them fixed on main (5). Changesets write a changelog entry per release, and removals and the 0.2.0 database reset are called out, though breaking changes arrive in minor versions before 1.0 (12). Version 0.5.0, and SECURITY.md says pre-1.0 (0).

HarnessRouter 35

Hosted reading, for HarnessRouter Cloud at api.harnessrouter.ai. No status page (status.harnessrouter.ai doesn't resolve and harnessrouter.ai/status answers 404), so 0 for the page and 5 for an unreadable incident record. No request rate limit with numbers was found. The pricing page states one task at a time on Free, unlimited concurrency on plans with brief queueing and a 30-minute or 1-hour task limit on Free, so 5 of 15. 429 is in the error table as rate_limited with Retry-After (UHP Errors §3), quota_exhausted is marked not worth retrying, and every task call takes an Idempotency-Key with a rule to recover the session rather than resend after a dropped stream (15). Terms §5.4 give no service level outside a signed order form (0). The task API isn't labelled beta, while tracing and agent memory are, and the protocol is a draft standard (10). 35 in all.

Transparency & trust HarnessRouter +15

Clawboo 58

MIT, Copyright 2026 Sanreds, with a third-party notices file (30). The docs list every file Clawboo writes, which copies of keys are encrypted and which are plain text, retention for stored tool results (7 days) and pending approvals (24 hours), and that prompts go only to connected providers. There is no privacy statement, and the website wasn't read (22). The 0.1.x line is deprecated on npm with a note in the changelog, and removals are dated in release notes, with no written deprecation policy or notice period (10). No telemetry, with the server's own outbound requests disclosed, though the npm update check has no setting (18).

HarnessRouter 73

Editorial half. The server, specification, schema and conformance suite are Apache-2.0. The Cloud's own billing and deployment wasn't confirmed to match the open code, and the Agent Skill has a custom licence for some guides (25 of 30). The privacy policy, DPA, subprocessor list and a retention page agree. Customer content isn't used for training without an opt-in, and periods are stated (tasks deleted at once, agents and files after 30 days, backups within 14 days, credentials within 90, free-plan task records 7 days). The privacy policy gives no periods of its own (24 of 30). UHP's versioning page says how a field is deprecated and that the previous version SHOULD be supported for six months. No dated product deprecation notices found (14 of 20). Subprocessors listed with purpose and location (Azure, Stripe, Vercel, Supabase, all United States), but the routing and inference gateway provider is named only on request (15 of 20). 78 in all.

Security & auth Clawboo +12

Clawboo 70

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 docs say Clawboo sends no telemetry and list the GitHub catalogue fetch, the npm version check, OpenRouter's public model list, Google Fonts and the GitHub star count, of which only the catalogue address can be changed (27). Clawboo Native shell commands are off by default and asked one at a time, and connector grants are per agent with approval on writes. Claude Code, Codex and Hermes run with their prompts and sandboxes off and no setting to change it, they can read Clawboo's database and key vault, and with no access token by default any local program can answer approval cards (8). Images in agent text don't load on their own, peer posts are marked as evidence, and a run that has read private data and untrusted content asks before any outbound connector call (11). An audit log of budget, breaker, approval, verification, tool-call and install events, with secrets masked (13). SECURITY.md with private reporting, CodeQL, Dependabot and npm provenance. No security.txt or bug bounty, OSV lists no advisory for clawboo, and the proxy advisory is on the docs with a workaround while its fix is unreleased (11).

HarnessRouter 58

Hosted reading. Bearer Workspace API keys, revocable at once through the API, held to one workspace or reaching the organisation, with harness-bound calibration credentials. No OAuth, per-endpoint scopes or expiry found (20 of 30). Least privilege 10 of 20. disabled_tools per configured agent, enforced by the runtime only where GET /v1/bases says hard, and per-turn cost and step caps, with no approval step for actions a harness takes. Prompt injection 10 of 15. UHP Security §4 puts injection in scope for the client, tells servers to keep harnesses that read untrusted input separate and forbids claiming an agent is safe on untrusted input, and secret values are redacted from responses, streams and traces. Operator visibility 10 of 15. A cost breakdown per task on every plan, and the step-by-step trace is beta, included in Scale or $50 a month. Security programme 8 of 20. A disclosure policy with safe harbour and no bounty, SECURITY.md with GitHub private reporting and a 10-working-day acknowledgement aim, GHSA identifiers cited in public fix commits, no security.txt and no SOC 2 or ISO 27001 found. 58 in all.

How the scores have moved

Verdicts

Clawboo

Tasks, memory, team chat and connectors are shared across five runtimes through four MCP servers, with documentation that states each default and limit. Claude Code, Codex and Hermes run with their sandboxes and approval prompts off and no setting to change it, and a reverse-proxy exposure of the MCP servers is fixed only on the unreleased main branch.

HarnessRouter

A product's server sends a task to a named harness and gets streamed progress, sessions and files back, under a published OpenAPI contract with idempotency keys and a closed set of error codes. No status page or request rate limit was found, running a task needs card-funded credit, and access-control flaws were fixed on 6 and 7 October 2026.

Before you call either

Clawboo

  1. Run npx clawboo@latest, not a bare npx clawboo, which can reuse an older cached build. Node.js 22.12 or newer is required
  2. On 0.5.0 behind nginx, Caddy or a Cloudflare Tunnel, deny /api/mcp/ at the proxy and set STUDIO_ACCESS_TOKEN from openssl rand -hex 24
  3. Give Claude Code, Codex and Hermes teammates only work you would let run unattended, or run Clawboo under a separate user account or VM
  4. Create a hard-cap budget in Settings > Insights > Governance before long runs. A fresh install has no budget and new budgets only warn
  5. Install @anthropic-ai/claude-agent-sdk globally beside Clawboo for Claude Code teammates. A one-off npx run cannot load it

HarnessRouter

  1. Name the harness yourself. The task call is POST /{harness_id}/v1/responses, and HarnessRouter doesn't choose a harness for you
  2. Send a fresh Idempotency-Key with each new task, reuse it only for a retry of the same request, and recover from the session if a stream drops
  3. Call cancel to stop work. Closing the SSE connection leaves the agent running and billing
  4. Keep the Workspace API key on the server. The docs forbid calling the API from a browser with it
  5. Check each tool's enforcement in GET /v1/bases. On bases marked instruction, disabled_tools is a request to the model, not a block
