Which one, for what

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.

Also in its favour

  • No incidents deducted, where Mistral Vibe CLI loses 14 points for them

Watch for

No new downloads or sign-ups since 4 November 2026

Mistral Vibe CLI C

Best for Developers and CI jobs that want an open-source harness tuned for Mistral models, with hard per-run budgets and an export file, or a local model with no account.

Watch for

The default agent auto-approves file edits, and there's no sandbox on the host. Isolation needs the experimental --agent-socket server or a container

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 Mistral Vibe CLI +60

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).

Mistral Vibe CLI 60

Harness reading of the published rubric, as for openai-codex and qwen-code. No payment protocol (0). Plan prices (Pro $14.99 a month, Team $24.99 a user a month) and per-token API prices for the default model ($1.5 and $7.5 per million) are public without a login (20). A Free plan includes limited coding sessions, and the docs document a fully offline set-up with a local model and no Mistral account. Whether the Free plan asks for a card wasn't checked (20). An agent can install the CLI and run it against a local OpenAI-compatible server with no sign-up, since a llama.cpp provider on 127.0.0.1:8080 is in the defaults (20). 0+20+20+20 = 60.

Reliability Mistral Vibe CLI +44

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.

Mistral Vibe CLI 69

Local-package reading. PyPI, uv, pip, Homebrew at 3.0.4 and an install script, with Python 3.12 or later stated and UNIX the supported target (20). A public CI workflow on push and pull request to main runs pre-commit, the test suite and a build and install smoke matrix, but GitHub's pages and API were refused in this session, so whether main is passing is unchecked (15 of 25). The 18 October issue counts came from shields.io badges, a third-party copy of GitHub data this run bars, so they are struck. Every release has a Fixed section in the changelog, and how many open issues are crashes or regressions, and how fast they're answered, couldn't be read (10 of 25). The changelog states Keep a Changelog and semver and marks breaking changes, but the hooks rename shipped in minor 2.21.0, patch 2.11.1 changed the -p approval default, patch 2.26.1 removed the bundled local model, and patches 3.0.3 and 3.0.4 carry marked config, model and session breaks (9). 3.0.4, classified Production/Stable (15). 20+15+10+9+15 = 69.

Agent ergonomics Mistral Vibe CLI +29

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).

Mistral Vibe CLI 84

Framework reading, adapted to a harness driven by a pipeline. --enabled-tools and --disabled-tools with globs and regex (in -p the first disables everything else), per-tool and per-MCP-tool permissions, and switches for subagents and background processes (20 of 25). --max-turns, --max-tokens, --max-price and --time-limit, with text, json and streaming output and an export file with usage and cost (20). Exit codes 0 to 4 with named outcomes, refusals reported with a code, and config problems listed under warnings (18). --resume SESSION_ID and --continue, SIGTERM stops a run so it can be resumed, and model API failures are retried before exit 2 (16). One required input (the prompt), a GitHub Action and the ACP server, but no SDK, and the app-server's JSON-RPC protocol isn't documented for outside use (10). 20+20+18+16+10 = 84.

Transparency & trust Mistral Vibe CLI +28

Conductor 53

Closed service with terms and privacy pages (15). The transition notice says when Cloud data deletion begins (20 November) and that all user data is deleted when the app shuts down in early 2027 (20 of 30). Dated shutdown notice (15 of 20). SOC 2 report on a trust portal, subprocessors not read (10 of 20). 15 + 20 + 15 + 10 = 60.

Mistral Vibe CLI 81

Apache-2.0, with LICENSE and pyproject in agreement (30). The README sends readers to Mistral's privacy policy (effective 3 September 2026), which names Vibe. The commercial terms (effective 25 September 2026) say no training on customer data unless a product's default or an opt-in allows it, and the pricing page lists model training as opt-out on Free, Pro and Team. The configuration reference calls telemetry anonymous without listing its fields. The offline guide now names enable_update_checks = false with enable_telemetry = false, as the source reads them (16 of 30; 14 on 18 October, when it named a key the source defines but never reads). Removals are listed in the changelog, deprecated settings are named in the configuration reference and warned about at startup, the agent socket may change without notice, and custom Python tools and the bundled local model were removed in patch releases with warnings (10 of 20). Telemetry is disclosed with an opt-out in the README and the configuration reference, and the README names the server-managed shell-tool rollout, but its fields are only in the source (14 of 20). 30+16+10+14 = 70.

Schema & documentation Mistral Vibe CLI +25

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).

Mistral Vibe CLI 85

Framework reading. A configuration reference with each key's type and default, the export.json fields, and the --agent-socket JSON-RPC methods with typed params and results in the README, plus ACP. Since 3.0.3 vibe config schema prints a JSON schema of every setting, including each built-in tool's; the streaming events still have no published schema (20 of 25). docs.mistral.ai/llms.txt indexes the CLI pages, each with a Markdown twin (10). The safety page says what each agent allows and when to use it, and on 2 November it agrees with the source. -p runs the configured default_agent and denies calls that need approval, and the offline guide and configuration reference name enable_update_checks. The 18 October contradictions and TODO notes are gone (15 of 20). Output formats, agent names, permission values and OpenTelemetry redaction modes are enums, and the config is validated on load (12). Many examples and an exit-code table that maps each code to the outcome names in export.json (13). Dated changelog and version tags (15). 20+10+15+12+13+15 = 85.

Maintenance & community Mistral Vibe CLI +15

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.

Mistral Vibe CLI 73

3.0.4 on 30 October 2026 (30). 21 release tags from 4 August to 2 November, 2.24.0 to 3.0.4, each with a dated changelog entry (20). The 18 October issue and pull request counts came from shields.io badges, a third-party copy of GitHub data this run bars, so they are struck. Response times couldn't be read. CONTRIBUTING.md says the project isn't accepting contributions, and the history is squashed release commits. Credit is for the dated changelog, the issue templates and the public advisory (8 of 25; 10 on 18 October with the counts). No SDK. vibe-acp is current in the ACP registry at 3.0.4 and the Homebrew formula is at 3.0.4 (8 of 15). Dependencies are pinned to exact versions, workflow actions are pinned by commit, and CI runs on main, but no Dependabot or Renovate config was found (7 of 10). 30+20+8+8+7 = 73.

How the scores have moved

Verdicts

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.

Mistral Vibe CLI

Apache-2.0 with releases most weeks, and headless runs capped by turns, tokens, price and wall time, with typed exit codes and an export file. File edits are auto-approved by default, the host has no sandbox, telemetry is on by default, and patch releases 3.0.3 and 3.0.4 shipped marked breaking changes.

Before you call either

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

Mistral Vibe CLI

  1. Pass --agent on every -p run (plan is read-only). The default is accept-edits, and an experiment can switch it to smart-approve
  2. Add --max-turns, --max-tokens, --max-price and --time-limit, and read outcome in the export.json that --output-dir writes. Exit 3 means a limit or a refusal
  3. Run in a container or behind --agent-socket before using --auto-approve, and set outside_workdir = "deny" to refuse paths outside the working directory
  4. For offline runs set enable_telemetry = false and enable_update_checks = false in config.toml
  5. Pin a version and read the changelog before upgrading, since patch releases can carry marked breaking changes; serve token usage from third-party model servers (stream_options.include_usage)
