Pros
  • DocsFactory's Droid agent posted a leading 58.75% on Terminal-Bench when Factory published the result.[1]
  • DocsThe $20/month Pro plan bundles the Factory app, Droid CLI, Droid SDK, local and cloud background agents and Managed Droid Computers.[1]
  • DocsBYOK is free up to an allowance on all individual plans, and a free pool of open-weight models (Droid Core) stays available after standard usage runs out.[1]
  • DocsExtra-usage credits are prepaid with a $10 minimum and never expire.[1]
  • User reportsCredited by users as the tool that defined terminal coding agents, with plan-style modes before Claude Code.[1][2][3]
  • User reportsUsers praise architect mode, where a pricier model plans and a cheaper one edits, as cost-effective.[1][2][3]
  • User reportsWorks with many models, including local ones via Ollama, and can be scripted.[1][2]
  • MetadataApache-2.0 and git-native: it commits its changes, so they are easy to review and revert.[1]
Cons
  • DocsThree independent rolling rate-limit windows (5-hour, 7-day and 30-day) govern usage, and Missions require Extra Usage and pause when they hit a limit.[1]
  • Independent testPricing has changed sharply, from $80/user token-metered tiers in early 2025 to rate-limited seats starting at $20, which makes long-term cost planning harder.[1]
  • Independent testBenchmark standing depends on the underlying model: one comparison lists Droid at 58.8% with Opus 4.1 and 52.5% with GPT-5 (medium).[1]
  • MetadataThe agent is proprietary, unlike open-source CLIs such as Aider or OpenCode, so you cannot self-host or audit it.[1]
  • User reportsLess autonomous: users note it lacked an automatic write-run-fix loop and defaulted to limited multi-turn recursion.[1][2]
  • User reportsSome users find it feels like chat in a terminal, with nagging prompts and 'too much busywork'.[1][2]
  • MetadataDevelopment has slowed: the last release was v0.86.0 (Aug 2025), the last push was May 2026, and 1,408 issues are open. Users report moving to newer harnesses.[1][2][3]
  • User reportsUsers report quality dropping in long conversations and heavy token use (2M tokens a day for one user).[1][2]
Best forEngineering teams that want one model-agnostic coding agent across CLI, IDE and background cloud runs.Developers who want a controlled, git-native pair programmer with explicit file context and any model.
Watch out forLong Missions can hit the rolling rate limits and run up Extra Usage charges.Slowing development and a less agentic loop than current harnesses.
