Which one, for what

Cline D

Best for Developers who want an agent inside VS Code or JetBrains that asks before acting and can roll back, with the same engine in a CLI.

Conductor E

Best for Existing Conductor users planning their move before Cloud closes on 20 November 2026 and the local app winds down in early 2027.

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 Cline +50

Cline 50

No payment protocol (0). Scored on Cline's paid options. ClinePass is $9.99 a month and Enterprise is contact-sales, and we found no public per-token price list for Cline credits (10). The open-source extension and CLI need no card (20). Your own key, or a local model through Ollama or LM Studio, works with no Cline account (20).

Conductor 0

No new sign-ups since 4 November, free users can't upgrade, and no price is shown. No protocol, no published price, no open free tier, no onboarding (0).

Reliability Cline +45

Cline 70

Read as a local package. The cline CLI on npm (Node 22 or later), the VS Code extension (VS Code 1.101 or later), a JetBrains plugin and desktop builds (20). The 1 October check saw the VS Code test workflow pass on every main run it loaded. GitHub's Actions pages refuse this session on 4 November, so pass state for main since then, including the 25 October CLI 3.0.74 and extension 4.1.26 releases, is unread (15, as node-red). 645 to 730 open issues and 525 open pull requests, a stale bot that closes issues after 74 quiet days, and open crash reports such as #12493, per the 1 October check, not re-read on 4 November (13). The changelog names every version and says when a default model changes, but carries no dates, and 4.0.0 listed its removals under Changed rather than a breaking section. CLI 3.0.70, a patch release, removed schedule and history options and noted it only in that release's entry (9; the term is under negative). Extension 4.1.26 and CLI 3.0.74 are past 1.0, while the SDK (0.2.0) and desktop app (0.0.49) aren't (13).

Conductor 25

Read as local software that is winding down. Installed from Conductor's own download, which stopped taking new users on 4 November 2026 (10). Closed source, so no public CI or issue tracker (0, 0). A dated changelog, newest 0.93.0 on 4 November (15). Version 0.93 (0). 10 + 0 + 0 + 15 + 0 = 25.

Maintenance & community Cline +27

Cline 85

CLI 3.0.74 and extension 4.1.26 on 2026-10-25, 10 days before this check (30). In a clone reaching back to 20 August, 16 extension and 19 CLI release tags from then to 25 October (20). Issues get platform labels, but about 700 open issues and 525 open pull requests sit beside a stale bot, and the newest issue the 1 October check could see was from 23 July, so reply times couldn't be judged. GitHub's issue pages refuse this session on 4 November (13). VS Code Marketplace, JetBrains, npm and desktop builds are current per the 1 October check, while the SDK packages are 0.2.0 (26 October) (13). Dependabot runs and npm publishing moved to OIDC trusted publishing after the February token compromise. CI pass state per the 1 October check (9).

Conductor 58

0.93.0 on 4 November 2026 (30). Several dated releases in 90 days, per the changelog index (20). Discord, a subreddit and email for support (8). Closed app, no package or CI to read (0). 30 + 20 + 8 + 0 + 0 = 58. The local app gets new models and critical fixes only until early 2027.

Schema & documentation Cline +17

Cline 77

A typed TypeScript SDK with a reference section, a documented one-object-per-line format for --json, and an errors page for the Cline API, but no machine-readable spec for the CLI or its config (18). llms.txt at docs.cline.bot, listing a Markdown version of every page (10). Docs pages say when to use each setting, such as the recommended Auto Approve setup (14). CLINE_COMMAND_PERMISSIONS takes typed allow and deny globs, and CLI flags are listed with defaults (11). CLI samples, SDK examples and the API errors page (13). A versioned changelog without dates, with dated tags on GitHub (11).

Conductor 60

Harness reading. Docs for workspaces, review and merge, a Conductor API reference page linked from the docs (not read), and security and permissions pages (60).

Agent ergonomics Cline +12

Cline 67

Harness reading of the framework line, scored on what an agent or pipeline driving it has to supply. Many built-in tools (files, terminal, browser, MCP, subagents, plan and act), with MCP servers switched on or off per server, and no tool search or lazy loading found (15). --timeout (off by default), a mistake limit through --retries, automatic compaction and an output budget scaled to the model (14). --json writes one JSON object per message, but we found no documented exit codes (12). Checkpoints restore files and task state, sessions resume by ID, and API errors and empty responses are retried (18). The CLI defaults to Cline's own provider and to approving every tool, and the SDK is TypeScript only (8).

Conductor 55

Harness reading. Each task gets a workspace, branch, terminal and diff, with pull requests and merges from the app, and an API for integrations; not re-read in detail (55).

Security & auth Cline +12

Cline 57

Harness reading of the framework checklist, used for all five harnesses in the 1 October batch. 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. Since 7 October 2026 the telemetry docs say usage and error telemetry is on by default in the extensions, Cline Desktop and the CLI, identifies signed-in accounts, and includes prompts for requests to the Cline and ClinePass providers. Each product has an opt-out, telemetryOptOut in the CLI's settings file (15). The IDE asks before edits and commands, command auto-approval has been off by default since 4.0.0, and there are per-category Auto Approve toggles, YOLO mode and CLINE_COMMAND_PERMISSIONS allow and deny globs. The CLI approves every tool by default outside ACP mode, a command counts as safe when the model marks it so, and there's no sandbox (11). No prompt-injection guidance found in the docs (4). Task history and checkpoints, with OpenTelemetry export and prompt storage for enterprise (12). A valid security.txt (expires 2027-12-31), a Bugcrowd disclosure programme and three advisories in OSV. GHSA-3cj3-hqcr-g934 now lists 3.0.30 as patched, and GHSA-5c57-rqjx-35g2 lists 2.13.0 as the last affected version (15).

Conductor 45

Closed app. Telemetry and data handling weren't read beyond the transition notice (10 of 30). A security and permissions page (10 of 20). No prompt-injection guidance found (5). No audit log found (5). SOC 2 Type II report at trust.conductor.build (15 of 20). 10 + 10 + 5 + 5 + 15 = 45.

How the scores have moved

Verdicts

Cline

Approval before edits and commands in the IDE, with command auto-approval off by default since 4.0.0. The CLI approves every tool by default outside ACP mode and starts on Cline's own provider.

Conductor

Conductor ran parallel coding agents on the Mac, and Meta is acquiring it. It has taken no new users since 4 November 2026, Cloud turns read-only on 13 November and shuts down on 20 November, and the local app winds down in early 2027, when all user data is deleted.

Before you call either

Cline

  1. Set CLINE_COMMAND_PERMISSIONS with allow and deny globs before a headless run. The CLI approves every tool by default
  2. Pick a provider with -P and a key, or run cline auth. The default provider needs a Cline sign-in
  3. Turn telemetry off before the first task. In the CLI set telemetryOptOut to true in ~/.cline/data/settings/global-settings.json, then run cline hub stop
  4. Pin the CLI version. 2.3.0 was a malicious publish
  5. Keep the hub on 127.0.0.1 or set ROOM_SECRET, and run 3.0.30 or later
  6. Pin the CLI version in scripts. Patch releases have removed options that now fail with "unknown option"

Conductor

  1. Export your data from Settings, Account, Export data before 20 November 2026
  2. Move Cloud workspaces to your Mac with Transfer to local before 13 November
  3. Plan a move off the local app before early 2027; see the agent-harnesses category for alternatives

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.
