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.

Reliability Orca +31

Cursor CLI 27

Local-package reading. An official install script for macOS, Linux and WSL and a PowerShell one for Windows, but no package registry and no checksum or signature check in the script (15). No public CI or test suite, since the source isn't published (0). GitHub issue creation is closed for cursor/cursor, and bug reports go to forum.cursor.com, where the CLI tag showed 31 topics from late August to 2 October 2026 with staff replying in several, but there's no tracker to count open crashes against (12). Date-based versions (2026.09.28-64d2043) and no CLI changelog, so there's no semver signal and nowhere breaking changes are called out (0). Not 1.0 and not declared stable. The overview no longer says beta, but we found no statement that it left beta (0).

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.

Agent ergonomics Orca +28

Cursor CLI 42

Framework reading, adapted to a harness driven by a pipeline. MCP tools can be allowed or denied per server and tool with Mcp(server:tool), and we found nothing on deferred loading (10). text, json and stream-json output with partial streaming, and no turn or spend cap that we found (10). No documented error format or exit codes (5). --resume and --continue (12). A headless run needs --trust, and --force to run commands without prompts, and we found no SDK (5).

Orca 70

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).

Schema & documentation Orca +26

Cursor CLI 39

Framework reading. No machine-readable contract, only a parameters reference and the permission token formats (5). cursor.com/llms.txt lists the CLI pages with Markdown twins (10). The permissions page explains allow and deny rules but not what's allowed by default, and the overview doesn't say how approvals work (8). Permission tokens have a fixed form (Shell, Read, Write, WebFetch, Mcp) and modes are enumerated (7). Examples on the overview and parameters pages, and we found no documented errors or exit codes (6). No CLI changelog, and versions are dates (3).

Orca 65

Harness reading. A docs site with CLI orchestration and native chat pages (65).

Payments & pricing Orca +15

Cursor CLI 25

Harness reading of the published rubric. No payment protocol (0). Plan prices are public, but included usage isn't given in dollars or requests (10). Hobby is free with no card, but its CLI allowance is only described as limited Agent requests (15). A person signs in through a browser to use it or to get an API key (0).

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.

Maintenance & community Orca +13

Cursor CLI 62

Version 2026.09.28-64d2043, dated 28 September 2026 (30). Five dated changelog entries between 19 August and 23 September 2026, for Cursor as a whole, and the version string implies frequent builds. Judgement call, since none of the entries is CLI-only (20). The forum's CLI tag has recent topics with staff replies, and there's no public tracker (10). No SDK found (0). No public CI, and an installer without integrity checks (2).

Orca 75

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 Cursor CLI +6

Cursor CLI 60

Closed source with clear terms from Anysphere, Inc. (15). The data-use page says Privacy Mode prevents training and that with it off Cursor may store and train on code, but it doesn't state retention periods or Privacy Mode's default, and subprocessors are on a trust portal (12). No deprecation policy or dated notices for the CLI (0). Client telemetry isn't documented, so there's no opt-out to credit (0).

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.

How the scores have moved

Verdicts

Cursor CLI

Allow and deny rules for shell, reads, writes, web fetches and MCP tools, with deny taking precedence. No CLI changelog, and versions are dates.

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.

Before you call either

Cursor CLI

  1. Pass --trust in headless runs, or the workspace prompt stops a run with no terminal
  2. Write deny rules in .cursor/cli.json before using --force. It runs any command they don't match
  3. Don't use --approve-mcps in repositories you didn't write. Two 2025 CLI advisories came through MCP
  4. Set CURSOR_API_KEY in CI. agent login opens a browser
  5. Record agent --version with each run. Versions are dates and there's no CLI changelog to compare against

Orca

  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

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
