Spec by spec

| Platforms | macos, linux, windows, web | macos, linux, windows, web |

| Runs terminal commands | Yes | Yes |
| Multi-file edits | Yes | Yes |
| Git operations | Yes | Yes |
| Browser control | YesBrowser tools drive Chrome or Chromium over the DevTools Protocol, which requires launching the browser with --remote-debugging-port and setting cdp_url in ~/.cosine/config.toml. | YesThe first-party Droid Control plugin (droid plugin install droid-control@factory-plugins) ships an `agent-browser` driver - a Playwright-backed CLI with Chrome DevTools Protocol support that navigates, fills forms, clicks and captures screenshots, powering /qa-test and /demo. |
| Sandboxed execution | YesRemote environments are isolated containers built from a Dockerfile; local runs are not sandboxed. | YesOS-level sandboxing isolates Droid from the filesystem and network using kernel-enforced policies (https://docs.factory.ai/autonomy-and-safety/sandbox.md). |
| Multi-agent orchestration | Yes | Yes |
| Headless / CI mode | No | Yes |
| Models | ||
| Backbone | Lumen Scout, Lumen Outpost, GPT-5.5, Claude Sonnet 4.6, Claude Opus 4.7, Gemini 3.1 Pro, DeepSeek, Kimi K2.6, MiniMax M2.7, Qwen | Claude, GPT, Gemini, open-source and local models via BYOK |
| Bring your own model | YesLimited to ChatGPT and Claude models accessed through your own provider account. | YesCustom models via `anthropic`, `openai` or `generic-chat-completion-api` providers with your own baseUrl and apiKey, plus an AWS Bedrock block with awsRegion/awsProfile. |
| Local models | No | YesBYOK config in ~/.factory/settings.json takes a baseUrl, so Ollama (http://localhost:11434/v1), LM Studio (http://localhost:1234/v1) and vLLM are all documented targets. |

| Bring your own key | YesYou can sign in with your own ChatGPT or Claude Max subscription, which routes billing to that provider instead of consuming Cosine credits. | Yes |

Which one would each critic pick
| Critic | Cosine | Factory Droid | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.3 | 7.3 | Factory Droid — Pick Droid if you want one agent in the terminal, in Slack and in CI; pick OpenCode if you would rather read the source and hold the keys yourself. |
| El Crítico | 6.0 | 6.3 | Factory Droid — The plans are priced in dollars and metered in rolling rate limits the pricing page does not publish, so the failure mode is being stopped, not being billed. |
| El Profesor | 5.5 | 6.8 | Factory Droid — Droid's 58.8% Terminal-Bench result names the model and the leaderboard, which is more than most vendors manage, and its harness design is documented in hooks, MCP and Missions. |
| La Inversora | 6.0 | 7.0 | Factory Droid — Factory is selling to the org chart, with Slack, Teams, a Teams tier and Enterprise custom, and that is the buyer who tolerates rate limits, so the pricing ladder is a feature. |
| La Jefa | 5.3 | 6.5 | Factory Droid — Sixty seats on Teams is about $2,460 a month plus a rate limit nobody can budget, but the headless CI mode and Slack integration are the shape a team actually adopts. |
| El Hacker | 5.8 | 4.8 | Cosine — Closed source, but it takes my own Claude or ChatGPT subscription, and the browser tools want a cdp_url in ~/.cosine/config.toml pointing at a Chrome I launched. |
