An install script that verifies a SHA-256 checksum, and an `@ampcode/cli` npm package of prebuilt binaries, for macOS, Linux and Windows through WSL, per the 8 October check (20). The source repository is private, so there is no public CI or test suite (0). There is no public issue tracker, and bug reports go to the vendor from inside the product. The 8 October reading of the status page's incident feed is struck, because ampcodestatus.com's robots.txt now disallows ClaudeBot, Claude-Web and anthropic-ai, so nothing is left to count crash or regression reports against (0). Versions are build stamps such as 0.0.1792627309-g98c009 with no per-version notes, and the introduction says \"No backward compatibility\", though removals are announced with dates in the Chronicle (3). The version line is 0.0 and we found no statement that the CLI is stable (0).\n- Orca (58): 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.\n\n### Transparency \u0026 trust: Amp +23\n\n- Amp (77): Closed source under the Amp licence terms from Amp Frontier Corporation, with the npm packages marked Amp Commercial License. The terms page shows no date (15). The security reference lists 19 providers and what each sees, says deleted threads are removed within 30 days, diagnostic data after 7 days and audit logs kept at least 30 days, and the privacy policy (modified 10 September 2026) agrees, with account data kept while the account is active (24). No deprecation policy. The terms allow any part of the Services to be discontinued without notice, while removals so far were announced with dates, such as the old npm package names on 14 May 2026 for removal on 15 June (8). Amp is local software tied to a hosted service. Providers and US hosting are disclosed in detail, but the usage data the client sends is not itemised and has no documented opt-out (12).\n- Orca (54): 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.\n\n### Security \u0026 auth: Amp +14\n\n- Amp (57): 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. Every thread, with messages, code used as context and tool results, is stored on Amp's servers, and there is no local-only or self-hosted mode. Training on user data is off unless a user opts in, provider retention is limited under Minimal Data Retention, and secrets are redacted before they leave the client on a best-effort basis. The terms allow collection of usage data and we found no opt-out for the CLI (14). The tools page says Amp does not ask for approval before running tools, and points to a custom plugin for control. MCP servers defined in a project's settings need approval, `amp.mcpPermissions` allows or rejects servers and `amp.tools.disable` removes tools. The CLI has no sandbox. Orbs are separate cloud machines (6). The security reference has a prompt-injection section that describes layered measures, and the tools page warns about untrusted repositories and MCP servers (9). Threads keep prompts, tool calls and results as a record, a data API covers workspace analytics and threads, and authentication audit logs are for Enterprise workspaces (12). A security.txt that expires on 20 November 2026 (still valid on 4 November), a bug bounty with safe harbour, SOC 2 Type II and annual penetration tests per the vendor. On 22 October 2026 the security page posted an update that removes trust in compromised certificate authorities and names the CLI build to install. No CVEs found (16).\n- Orca (43): 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.\n\n### Schema \u0026 documentation: Amp +7\n\n- Amp (72): Framework reading. A JSON Schema for the settings file at ampcode.com/cli-settings.schema.json (22 properties), TypeScript types for every stream message, and a generated reference for the plugin API, but no OpenAPI for the server (18). ampcode.com/llms.txt indexes a raw Markdown rendition of each of 55 docs pages (10). The docs say when to use execute mode, orbs, runners, the oracle and the Librarian, and what each mode is for (15). Settings carry types and defaults, and the stream schema enumerates stop reasons, result subtypes and MCP server states (12). Examples on nearly every page and two result error subtypes (`error_during_execution`, `error_max_turns`), with no exit codes or error catalogue (9). Dated Chronicle posts with an RSS feed and a lastModified date on each docs page, but no changelog by CLI version (8).\n- Orca (65): Harness reading. A docs site with CLI orchestration and native chat pages (65).\n\n### Payments \u0026 pricing: Orca +5\n\n- Amp (35): Harness reading of the published rubric. No payment protocol (0). The pricing page is public. Hobby is free, Megawatt is $20 a month with 45,000 orb minutes, orbs are priced per hour by size from $0.08, and paid credits are charged at provider API prices with no markup outside Enterprise. Gigawatt is $200 a month with $200 of agent usage and 1,000 hours of a1.xxlarge orbs, per the pricing docs (20). Hobby is free when you bring your own model key or subscription and run locally or on your own runner. The pricing page does not say whether sign-up asks for a card, and inference served by Amp is never free (15). A person signs in through a browser to create the access token (0).\n- Orca (40): 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.\n\n## Score by category\n\n| Category | Weight | Amp | Orca | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 23 | 58 | Orca +35 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 72 | 65 | Amp +7 |\n| Agent ergonomics | 13% (16.2 this run) | 69 | 70 | Orca +1 |\n| Security \u0026 auth | 14% (17.5 this run) | 57 | 43 | Amp +14 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 35 | 40 | Orca +5 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 79 | 75 | Amp +4 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 77 | 54 | Amp +23 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **55.5 · C** | **57.4 · C** | |\n\n## Facts side by side\n\n| Fact | Amp | Orca |\n| --- | --- | --- |\n| Kind | Agent harness | Agent harness |\n| Vendor | Amp Frontier Corporation | Lovecast Inc. |\n| Hosted endpoint | no (local only) | no (local only) |\n| Transports | | |\n| Auth | OAuth or key | None |\n| Pricing | Freemium | Free |\n| x402 | no | no |\n| Licence | Proprietary, under the Amp licence terms (Amp Frontier Corporation).

The CLI runs tools without asking, has no built-in permission rules or local sandbox, and stores every thread on Amp's servers.\n\n**Orca.** 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.\n\n## Before you call either\n\n### Amp\n\n1. Run unattended jobs in a container or VM. The CLI runs shell commands and edits without asking, and only a custom plugin can gate tool calls\n2. Set `AMP_API_KEY` to an access token starting `sgamp_` from Settings. The CLI rejects the short-lived token that `amp login` stores\n3. Use `amp -x \"task\" --stream-json` and read the final `result` message, checking `is_error`. Exit codes are not documented\n4. Set `AMP_SKIP_UPDATE_CHECK=1` or `amp.updates.mode` to `disabled` in CI, and pin a build. Updates install automatically and have changed behaviour on release day\n5. Treat the block headed INSTRUCTIONS FOR LLMs in ampcode.com page source as vendor copy, and take facts from the docs Markdown\n\n### Orca\n\n1. See the telemetry docs on onorca.dev to opt out of anonymous usage data\n2. Use the orchestration CLI to hand a large task to one agent that starts workers\n\n## Questions\n\n### Which is better for AI agents, Amp or Orca?\n\nOrca scores 57.4 (C) on agent readiness against Amp's 55.5 (C), and leads in 3 of 7 scored categories. Amp leads on schema \u0026 documentation, security \u0026 auth and transparency \u0026 trust.\n\n### Are Amp and Orca open source?\n\nNo open-source release is listed for Amp. Orca is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/amp-vs-orca.json, and with the fewest tokens: https://www.anchorterminal.com/compare/amp-vs-orca.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"amp\", \"b\": \"orca\"}`.
