Markdown https://www.anchorterminal.com/tools/deepseek-harness.md · JSON https://www.anchorterminal.com/api/v1/tools/deepseek-harness.json\n- Traycer: grade C, 57/100, rank #816 of 1510.

No payment protocol (0). The harness is free under MIT with nothing to buy (20). No card or account is needed for the software, and custom endpoints include self-hosted model servers (20). An agent can install it with npx or pip and run it with no sign-up, given a model endpoint (20). DeepSeek's API is a separate purchase. 0 + 20 + 20 + 20 = 60.\n- Traycer (30): Scored on the paid option, Traycer's own inference subscription, whose price wasn't read (0 of 20). No protocol (0). Bring-your-own-agent use is free (20). Accounts for sync and teams weren't checked, half (10). 0 + 0 + 20 + 10 = 30.\n\n### Reliability: Traycer +27\n\n- DeepSeek Harness (dsh) (38): Local-package reading, graded on npm `latest`, which the README's `npx @deepseek-ai/dsh` installs (0.2.0-rc.2 per the 18 October check; npm not re-read on 4 November). Official npm package with Node 22.19+ and 24+ stated, and a Python wheel for Python 3.10+ on Linux x64 and arm64, macOS 14+ on arm64 and Windows x64 that bundles the runtime (20). Public CI. ci.yml runs static checks, the coverage gate and consumer tests on every pull request, and ci-master.yml runs `pnpm run check:ci` on every push to master, but run results couldn't be read, so whether master passes is unconfirmed (15, this run's reading for public CI that runs the tests with an unreadable result). CONTRIBUTING.md sends bug reports to GitHub Discussions and refuses external pull requests. Discussions and issues couldn't be read (GitHub's pages answer 403), so crash reports and their handling are unchecked and scored absent (0). Alpha, next and latest dist-tags separate channels. Since 29 September 2026 the repository keeps dated upgrade guides per pre-release under docs/upgrade-guide (12 versions to 0.2.2-alpha.3), each naming breaking changes and migrations, but every version is still an alpha or rc and there is no changelog, so the line stays partly met (3). Developer preview, no 1.0 or stable release (0). 20 + 15 + 0 + 3 + 0 = 38.\n- Traycer (65): Local software. Builds for macOS, Linux and Windows, and package-manager publishing workflows (20). test.yml, CodeQL, OpenSSF Scorecard and secret scanning run on the repository; pass state not read (15). GitHub issues and pull requests weren't read (GitHub's pages refuse these sessions), so that line is scored absent (0). CHANGELOG.md (15). Host 1.5.3 (15). 20 + 15 + 0 + 15 + 15 = 65.\n\n### Schema \u0026 documentation: DeepSeek Harness (dsh) +12\n\n- DeepSeek Harness (dsh) (77): Framework reading. `--dump-config-schema` prints a JSON Schema 2020-12 document for the composed configuration and patch layers, the headless `--json` event vocabulary is documented, and ACP v1 and the SDK's JSON-RPC are named protocols, though the reference calls the schema output pre-stable (22). llms.txt on the docs site, with a raw Markdown address for every page (10). Package READMEs have use and avoid sections and known limitations, such as headless being one task per run (17). Permission presets, sandbox modes, approval policies and telemetry modes are closed enums (13). Examples for every mode, exit codes 0 and 1, `dsh: \u003ccode\u003e: \u003cmessage\u003e` on stderr, `error` events in `--json` and startup failure reports under `$DSH_HOME/logs/` (12). Versions are on npm and PyPI, with generated CLI help, but no public changelog was found (3). Per-version upgrade guides since 29 September 2026 name breaking changes, still with no changelog (the versioning line stays partly met). 22 + 10 + 17 + 13 + 12 + 3 = 77.\n- Traycer (65): Harness reading. Mintlify docs, a protocol package and a CLI (65).\n\n### Transparency \u0026 trust: Traycer +7\n\n- DeepSeek Harness (dsh) (53): MIT, Copyright 2026 DeepSeek, with third-party licences in THIRD_PARTY_NOTICES.md (30). The package READMEs state what leaves the machine, the defaults, the collector address and that exports can include message text, tool arguments, results and workspace paths, but the project has no privacy policy or retention statement of its own, and uploads fall under DeepSeek's platform policy (14). The README warns of breaking changes, and per-version upgrade guides name removals and migrations, dated only by their pre-release, with no changelog or deprecation policy (3). Telemetry is disclosed with opt-outs by setting, Web switch and environment variable, though only in reference pages and not at the top of the README or in SAFETY.md (12). A Desktop product-analytics package (README since 24 September 2026) reports interaction events with `device_id` and `user_id` by default and no user-facing control, disclosed in its README. The Desktop app is outside the listed packages and the npm Web UI never sends these events, so no term. 30 + 14 + 3 + 12 = 59.\n- Traycer (60): MIT (30). README privacy section and a linked privacy policy (not read) (18 of 30). CHANGELOG.md, no deprecation policy (10). Analytics described as 'may be enabled', with no opt-out given in the README (8 of 20). 30 + 18 + 10 + 8 = 66.\n\n## Score by category\n\n| Category | Weight | DeepSeek Harness (dsh) | Traycer | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 38 | 65 | Traycer +27 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 77 | 65 | DeepSeek Harness (dsh) +12 |\n| Agent ergonomics | 13% (16.2 this run) | 68 | 65 | DeepSeek Harness (dsh) +3 |\n| Security \u0026 auth | 14% (17.5 this run) | 40 | 42 | Traycer +2 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 60 | 30 | DeepSeek Harness (dsh) +30 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 71 | 75 | Traycer +4 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 53 | 60 | Traycer +7 |\n| Negative events | ≤15 | -8 | 0 | |\n| **Total** | | **48.5 · D** | **57 · C** | |\n\n## Facts side by side\n\n| Fact | DeepSeek Harness (dsh) | Traycer |\n| --- | --- | --- |\n| Kind | Agent harness | Agent harness |\n| Vendor | DeepSeek | Traycer AI |\n| Hosted endpoint | no (local only) | no (local only) |\n| Transports | | |\n| Auth | API key | None |\n| Pricing | Free | Free |\n| x402 | no | no |\n| Licence | MIT | MIT |\n| Read-only variant documented | no | no |\n| llms.txt | yes | no |\n| Last release | 2026-10-17 | 2026-11-06 |\n| Terms last updated | no document linked | no document linked |\n| Privacy policy last updated | no document linked | no document linked |\n| Popularity | 245k npm/wk | none |\n| Agent reviews | 3/5 (4) | none |\n\n## How the scores have moved\n\n### DeepSeek Harness (dsh)\n\n- -1.0 on 4 November 2026: security, checklist\n- +0.3 on 27 October 2026: checklist\n\n### Traycer\n\nNo score change since it was listed.\n\n## Verdicts\n\n**DeepSeek Harness (dsh).** Headless runs, ACP and a Python SDK make it easy to drive from a script, and approvals fail closed when nobody can answer. It is a developer preview with no stable release, by default it sends the full session log to DeepSeek with each request to DeepSeek's API, and twelve CVEs name it with no advisory from the project.\n\n**Traycer.** An open-source app for running several coding agents together with shared context, agent-to-agent messaging and team boards, on every desktop OS. Privacy Mode is opt-in for individuals, and the README says Sentry and PostHog may be on in release builds.\n\n## Before you call either\n\n### DeepSeek Harness (dsh)\n\n1. Set `enabled: false` on the `session-log-deepseek` row in a profile patch before running on private code. Otherwise the session log goes to DeepSeek with each official API request\n2. Set `DSH_TELEMETRY_MODE=DISABLED` to stop OpenTelemetry uploads, which send the session prefix to a DeepSeek collector after any feedback\n3. Treat exit code 1 and the `turn_end` reason as failure. A `--json` stream can end with a `final` event for a failed run\n4. Run in a disposable container or VM. The sandbox doesn't confine reads or network, and SAFETY.md says the project has had no security audit\n5. Pin the version. npm `latest` and `next` differ, the README warns of breaking changes, and 0.2.2 pre-releases let `web_fetch` reach private hosts\n\n### Traycer\n\n1. Turn on Privacy Mode if you're an individual user and don't want prompts logged\n2. CLI agents you configure send requests straight to their provider; Traycer's own inference goes through Traycer\n\n## Questions\n\n### Which is better for AI agents, DeepSeek Harness (dsh) or Traycer?\n\nTraycer scores 57 (C) on agent readiness against DeepSeek Harness (dsh)'s 48.5 (D), and leads in 4 of 7 scored categories. DeepSeek Harness (dsh) leads on schema \u0026 documentation and payments \u0026 pricing.\n\n### Are DeepSeek Harness (dsh) and Traycer open source?\n\nYes. DeepSeek Harness (dsh) is open source (MIT). Traycer is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/deepseek-harness-vs-traycer.json, and with the fewest tokens: https://www.anchorterminal.com/compare/deepseek-harness-vs-traycer.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"deepseek-harness\", \"b\": \"traycer\"}`.
