Codeium vs GitHub Copilot (2026): Codeium Is Now Devin Desktop
If you are comparing Codeium and GitHub Copilot (Agentdex profile) in 2026, the first thing to know is that Codeium no longer exists under that name. Codeium renamed itself Windsurf in April 2025, Cognition agreed to acquire Windsurf in July 2025, and on June 2, 2026, Windsurf became Devin Desktop (Agentdex profile). So the real comparison today is Devin Desktop versus GitHub Copilot. This guide explains what changed, then compares the two on features, editors and pricing as of October 24, 2026, using official pages from Cognition and GitHub.
Key Takeaways
- Codeium became Windsurf (April 2025), was acquired by Cognition (July 2025) and is now Devin Desktop (June 2026).
- The old Codeium extensions are winding down: the JetBrains plugin is in maintenance mode, and the VS Code plugin is no longer listed on the VS Code Marketplace.
- Devin Desktop is a full AI editor and agent manager. Plans: Free, Pro $20/month, Max $200/month, Teams and Enterprise.
- GitHub Copilot works inside the editor you already use. Plans: Free, Pro $10/month, Pro+ $39, Max $100, Business $19/seat and Enterprise $39/seat.
- Pick Copilot if you want to stay in your current IDE and on GitHub. Pick Devin Desktop if you want one place to run local and cloud agents.
What happened to Codeium?
Codeium started as Exafunction in 2021 and rebranded to Codeium in 2022, offering AI autocomplete extensions for many editors. In November 2024 it launched the Windsurf Editor, and on April 4, 2025, the company renamed itself Windsurf and its Codeium extensions became the Windsurf Plugins.
On July 14, 2025, Cognition, the maker of the Devin AI agent, signed an agreement to acquire Windsurf, including its product, brand and team. On June 2, 2026, Windsurf became Devin Desktop through an over-the-air update. Existing plans, pricing, extensions and settings carried over, and Devin Local replaced Cascade as the built-in agent.
The old plugins have not kept up. Cognition's docs say the Windsurf JetBrains plugin is in maintenance mode and recommend using Devin in JetBrains IDEs through the Agent Client Protocol (ACP) instead. The "Windsurf Plugin (formerly Codeium)" for VS Code is marked as unpublished on the VS Code Marketplace. If you used Codeium as a plugin, your realistic choices now are Devin Desktop, Copilot or another assistant.

Features compared
Code completion
Both offer inline suggestions. Devin Desktop includes Tab completions and Supercomplete, which predicts your next edit, and inline edits and Tab are unlimited even on the Free plan. Copilot Free includes 2,000 completions a month, and code completions and next edit suggestions are unlimited on all paid plans.
Agents
Devin Desktop puts an Agent Command Center front and center: a Kanban view of local and cloud agent sessions, Spaces for sharing context between them, and handoff between Devin Local on your machine and Devin Cloud. It also supports ACP, so agents such as Codex (Agentdex profile), Claude Agent and OpenCode can run inside it.
Copilot offers agent mode in the IDE and the Copilot cloud agent, which works on tasks in the background and opens pull requests. Copilot also supports third-party agents (in public preview), MCP and Copilot code review.
Models
Devin's Pro plan includes frontier models from OpenAI, Anthropic, Google and SpaceXAI, open-source models and Cognition's own SWE-2. Copilot's paid plans include a range of Anthropic, OpenAI, Google and xAI models, with premium models on Pro+ and higher. Copilot Free and Student use automatic model selection only.
Code review
Devin Desktop has Devin Review built in for reviewing diffs; it is usage-billed after a free trial, and free for open-source repositories. Copilot code review is included in Copilot's plans, with only "Review selection" in VS Code on the Free plan.
Editor choice
This is the biggest practical difference. Copilot works in the IDE you already use, which matters for teams on Visual Studio, Xcode or Eclipse. Devin Desktop asks you to switch editors, although it is compatible with VS Code extensions and keybindings.
Pricing compared
Devin Desktop plan | Price | GitHub Copilot plan | Price |
|---|---|---|---|
Free | $0 | Free | $0 |
Pro | $20/month | Pro | $10/month (1,500 AI credits) |
Max | $200/month | Pro+ | $39/month (7,000 AI credits) |
Teams | $80/month min + $40/full seat | Max | $100/month (20,000 AI credits) |
Enterprise | Custom | Business / Enterprise | $19 / $39 per seat per month |
Copilot meters chat and agent use in GitHub AI Credits worth $0.01 each, and extra usage is billed at that rate. Devin uses daily and weekly quotas without published numbers, with extra usage at API pricing. In short, Copilot is cheaper to start and easier to forecast, and Devin's higher tiers are built for people running agents most of the day. See Devin pricing and Windsurf pricing for more detail.
Which should you choose?
- Choose GitHub Copilot if you want to keep your current IDE, your code lives on GitHub, or you want the lowest predictable cost for a team.
- Choose Devin Desktop if you want an AI-first editor, run several agents at once, or already use Devin for cloud tasks.
- Former Codeium plugin users: Copilot is the closest like-for-like replacement for an in-IDE assistant. Devin Desktop is the official successor if you are willing to switch editors.
