# Orca > Orca is an open-source app that runs Claude Code, Codex and other coding agents in parallel, each in its own worktree, in chat or terminal, on a laptop or in the cloud, with an orchestrator that splits tasks across workers. - Canonical: https://www.anchorterminal.com/tools/orca - Pricing: https://www.anchorterminal.com/tools/orca#pricing - Reviews: https://www.anchorterminal.com/tools/orca#reviews - Markdown: https://www.anchorterminal.com/tools/orca.md (~4,450 tokens) - Slim: https://www.anchorterminal.com/tools/orca.min.md (~830 tokens, same facts, less prose, for token-sensitive contexts) - JSON: https://www.anchorterminal.com/tools/orca.json (this page as data, same URL with Accept: application/json) - Site index for agents: https://www.anchorterminal.com/llms.txt (the key docs and every listing in one file, at most 16 MB, about 4 million tokens: https://www.anchorterminal.com/llms-full.txt) - API: https://www.anchorterminal.com/api/v1/index.json - MCP: https://www.anchorterminal.com/mcp (the whole catalogue as tools, no key) - DNS: dig +short TXT orca.grade.anchorterminal.com (the grade as a DNS TXT record, for a sandbox with no HTTP where names still resolve; also top., best.. and .vs.. under the zone, and the same under grade.letme.dev) - Licence: CC BY 4.0, credit Anchor Terminal and link this page (https://www.anchorterminal.com/terms/#data) - Updated: 2026-11-07 ## Overview **Grade C · 57.4/100 · rank #791 of 1486 · #25 in Agent harnesses · not agent-ready · confidence low** ## Assessment An open-source orchestrator for coding agents with worker agents in their own worktrees, chat and terminal views, a browser and a CLI, on desktop and mobile, with heavy test automation. It collects anonymous usage data by default, and the cloud option's pricing wasn't found. ## Facts | Field | Value | | --- | --- | | Vendor | Lovecast Inc.

Confidence: low. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. "This run" is each category's share of the 100 points. | Category | Weight | This run | Score (0–100) | Points | | --- | --- | --- | --- | --- | | Reliability | 16% | 20 | 58 | 11.6 | | Performance | 10% | pending | pending | n/a | | Schema & documentation | 13% | 16.2 | 65 | 10.6 | | Agent ergonomics | 13% | 16.2 | 70 | 11.4 | | Security & auth | 14% | 17.5 | 43 | 7.5 | | Payments & pricing | 10% | 12.5 | 40 | 5.0 | | Task success | 10% | pending | pending | n/a | | Maintenance & community | 7% | 8.8 | 75 | 6.6 | | Transparency & trust (editorial 68, provenance 40) | 7% | 8.8 | 54 | 4.7 | | Negative events | up to −15 | up to −15 | none recorded | 0 | | **Total** | | | | **57.4 → C** | ### Why each score - Reliability 58 (checked 2026-11-07): Local software. Desktop and mobile builds and a Homebrew cask (20). Unit, end-to-end and platform test workflows; 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). Tags to v1.4.251, no changelog file (8). Version 1.4 (15). 20 + 15 + 0 + 8 + 15 = 58. - Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes. - Schema & documentation 65 (checked 2026-11-07): Harness reading. A docs site with CLI orchestration and native chat pages (65). - Agent ergonomics 70 (checked 2026-11-07): Harness reading. An orchestrator agent that splits work across workers in their own workspaces, chat or raw CLI, a browser and a CLI in one app (70). - Security & auth 43 (checked 2026-11-07): Harness reading. Anonymous usage data with an opt-out, per the README's link to its telemetry docs (15 of 30). Worktrees per agent and a sandboxed Linux build (12 of 20). No prompt-injection guidance (5). No audit log (5). A dependency-security workflow (6 of 20). 15 + 12 + 5 + 5 + 6 = 43. - Payments & pricing 40 (checked 2026-11-07): Scored on the cloud option. No protocol (0). The cloud price wasn't found on the pages read (0). The desktop app is free and MIT with no card (20). The local app needs no sign-up that we found (20). 0 + 0 + 20 + 20 = 40. - Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored. - Maintenance & community 75 (checked 2026-11-07): Tags to v1.4.251 and commits on 6 November 2026 (30). Many releases in 90 days (20). GitHub issues and pull requests weren't read (GitHub's pages refuse these sessions), so that line is scored absent (0). Current builds (15). Extensive CI (10). 30 + 20 + 0 + 15 + 10 = 75. - Transparency & trust 54 (checked 2026-11-07): MIT (30). Privacy and telemetry docs on the site (not read) (18 of 30). No deprecation policy (5). Disclosed with an opt-out (15 of 20). 30 + 18 + 5 + 15 = 68. Fix list, everything this grade says the listing lacks, the biggest gain first (12 items). What it covers is at https://www.anchorterminal.com/fixes/orca.md (JSON https://www.anchorterminal.com/fixes/orca.json). The whole list for a coding agent comes from `POST https://www.anchorterminal.com/api/v1/fix-list` with `{"listing": "orca", "plan": "read"}`, free while the beta runs ### What we couldn't check - unchecked: cloud pricing, the telemetry docs and issues ### Sources - repository README, licence, workflows, tags and docs, shallow clone: (seen 2026-11-07) - lead, the Conductor alternatives list the founder pasted on 7 November 2026, and awesome-agent-orchestrators: (seen 2026-11-07) ## Score history Every move of a score since the listing was graded, newest first, with its cause.

Not legal advice. **Terms of service**. Nothing is hosted by the vendor, so there are no terms of service to read. The MIT licence stands in and the check scores in full. **Privacy policy**. Nothing is hosted by the vendor, so there is no privacy policy to read and the check isn't scored. ## Live (updated 2026-11-07 16:01 UTC) - security.txt: none - Always current: https://www.anchorterminal.com/api/v1/live/orca.json ## Probe metrics Not measured yet. Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. Live uptime, where we poll the endpoint, is under Live and doesn't change the score. ## Strengths - An orchestrator agent splits a task across worker agents in their own workspaces - Chat UI or the raw CLI, switching without losing context - Desktop and mobile apps and a CLI - MIT, with extensive unit and end-to-end CI ## Weaknesses - Anonymous usage data collected by default, with an opt-out - Cloud pricing not found on the pages read - No changelog file ## Before you call it (notes for agents) 1. See the telemetry docs on onorca.dev to opt out of anonymous usage data 2. Use the orchestration CLI to hand a large task to one agent that starts workers ## Connect Install: ```bash Download from the releases page or Homebrew (Casks in the repository) ``` ## Similar tools Ranked by shared capabilities, then score.

The badge or a plain link to this page verifies the listing, from a page on onorca.dev or one of its subdomains, or the README at the root of github.com/stablyai/orca. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{"slug": "orca", "url": "…"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp.
