Which plan to pickStart with the 14-day trial. Essentials is enough for most small teams; you only pay for developers who open pull requests. Turn on usage-based reviews ($0.25 a file) with a monthly cap if you keep hitting the hourly limit.Pro at $20 is the place to start, and it is the only sensible way to try the cloud agent. Watch your quota for the first fortnight, and use cheaper models for routine jobs before deciding whether Max or Teams is worth it.If you already have ChatGPT Plus, you have Codex: just try it. If you are choosing between this and Claude Code with no existing subscription, Plus at $20 and Claude Pro at $20 cost the same, so pick whichever chat assistant you prefer. If you outgrow Plus, Pro starts at $100 and has no five-hour limit for now. The $200 tier gives new subscribers less usage than it used to, and Ultrafast mode is only on the $500 tier.

Pros and cons

AttributeCodeRabbitDevinOpenAI Codex
Pros
  • Set up in minutes and reviews every pull request automatically
  • Catches real bugs, including ones the coding agent missed
  • Works with any coding agent or editor
  • Free for open-source projects
  • Learns your preferences when you reply to it
  • Truly hands-off: it works in the background and returns a pull request

  • Picks up tasks from Slack, Teams, Linear and Jira
  • Wide model choice, including cheap open models and its own SWE-2
  • New frontier models usually arrive within days of launch

  • Cloud tasks let you start work from anywhere and come back later
  • Strong on tough, multi-file coding jobs
  • The CLI is open source and works with an API key
Cons
  • Marketed as unlimited, but hourly caps and fair-use throttling frustrate heavy users
  • Can be noisy, with nitpicks mixed in with real problems
  • Per-developer pricing adds up for bigger teams
  • Some users report billing mistakes, refund trouble and slow support
  • Success drops sharply on vague or complex tasks, so a developer still has to review everything
  • The daily and weekly quota is opaque, and good models can use a day's allowance in minutes
  • The free SWE-2 model, a big reason people subscribe, goes back to paid use after 1 November 2026
  • Users report slow support, including over unexpected on-demand charges
  • The Windsurf-to-Devin switch left gaps between the desktop and cloud versions, and some leftover clutter
  • Five-hour and weekly limits bite on Plus if you use it seriously
  • Cloud tasks use more of your allowance than local ones
  • It asks fewer questions than Claude Code before changing things
  • Model names and limits change often, which makes it hard to plan costs
  • The $200 Pro tier now gives new subscribers less usage than before
