Windsurf Plugin (formerly Codeium) vs OpenAI Codex
Pricing
Windsurf Plugin (formerly Codeium): Brand retired, plugin in maintenance mode under Devin Desktop
OpenAI Codex: Included in ChatGPT plans (Plus $20/mo, Pro from $100/mo), limited use on Free and Go
Description
Windsurf Plugin (formerly Codeium): The Codeium autocomplete extension, renamed Windsurf Plugin in 2025 and now a maintenance-mode companion to Devin Desktop, formerly Windsurf IDE
OpenAI Codex: OpenAI's coding agent, which works in the ChatGPT desktop app, your terminal, your editor and the cloud on your ChatGPT plan
Pros
- Existing installs keep working in VS Code, JetBrains, Visual Studio, Vim, Neovim, Jupyter, Chrome and Eclipse
- Keeps AI completions in your current editor instead of switching IDEs
- Runs in the ChatGPT desktop app, the CLI, an IDE extension and on the web, all tied to one ChatGPT account
- Cloud tasks keep going after you close your laptop, in a reusable environment for each repo
- Reviews GitHub pull requests when you tag @Codex or turn on automatic reviews
Cons
- All plugins are in maintenance mode: no new features
- Cascade in the JetBrains plugin is being deprecated, and the JetBrains remote plugin is no longer maintained
- The maker recommends Devin Desktop, or Devin over ACP in JetBrains, instead
- Free and Go plans only get limited use in the desktop app, on the smaller GPT-6 Luna model
- Plus usage is counted per five-hour window and weekly limits can also apply, and how far it goes depends on the model and the size of the task
- Running it on an API key instead of a plan drops the cloud features, such as GitHub code review and Slack
Details
Codeium was a free AI autocomplete extension that worked in almost any editor: VS Code, JetBrains, Vim, Emacs and more. Its company built the Windsurf editor on top of it and, in April 2025, renamed itself Windsurf, retiring the Codeium brand and renaming the extensions Windsurf Plugin. Cognition bought the Windsurf business later in 2025 and renamed the editor Devin Desktop on 2 June 2026. codeium.com now opens the Devin Desktop site.
The plugins still exist, but Cognition’s documentation lists all of them as in maintenance mode and recommends the Devin Desktop editor, or Devin over ACP inside JetBrains IDEs. For AI completion in your current editor with active development, GitHub Copilot is the usual choice. If you are willing to switch editors, Devin Desktop or Cursor give you completion plus agent features.
Codex is OpenAI’s coding agent. You hand it a task, such as a hard-to-find bug, a refactor or a new feature, and it reads the code, makes the changes and checks its own work, using browser and computer tools where it needs them. It can run several agents in parallel, and cloud tasks carry on while your laptop is closed.
It comes with ChatGPT, so if you already pay for Plus you already have it. The same account works in the desktop app, the terminal, your editor and on iOS.
OpenAI describes Plus at $20/month as enough for a few focused coding sessions a week. Heavier use means Pro, from $100/month, which currently has no five-hour limit, or buying extra credits when you hit the limit. You can also run the CLI on an API key and pay standard API rates, which suits automation such as CI.
