AI Coding Assistants Compared: Copilot, Cursor and Codeium for Real Projects
Three tools lead the AI coding assistant market in 2026. They are GitHub Copilot, Cursor, and Devin Desktop, the editor formerly known as Codeium and Windsurf. They look similar in a demo. They differ in form, price, and control. Copilot is an AI layer that lives inside the editor you already use. Cursor is a full editor rebuilt around an AI agent. Devin Desktop is an AI-first editor with its own agent, Cascade, plus a cloud agent service. This comparison uses prices and features from each vendor's own pricing page, checked on 7 November 2026. It is research-based. We did not run hands-on tests for this article.
AI Coding Assistants Compared at a Glance
The table below gives the short version. The sections after it explain the trade-offs behind each row.
| GitHub Copilot | Cursor | Devin Desktop | |
|---|---|---|---|
| Form | AI layer in your IDE, CLI, and GitHub.com | Its own AI-first editor, a VS Code fork | AI-first editor, a VS Code fork, plus cloud agents |
| Entry paid price | Pro, $10 per month | Plus, $8 per month | Pro, $20 per month |
| Free tier | Free, with 2,000 completions a month | Free, with limited agent requests | Free, with a light agent quota |
| Agent mode | Agent mode in IDEs, plus a cloud agent that opens pull requests | Agent with Plan Mode; cloud agents from Premium up | Cascade agent; Devin Cloud agents from Pro up |
| Model choice | Model choice varies by plan | Grok models included; Claude, GPT, and Gemini at API list price from Premium up | Frontier models from OpenAI, Claude, Gemini, and SpaceXAI on Pro |
| Privacy control | Training opt-out for individuals; Data Protection Agreement for Business and Enterprise | Privacy Mode: code is not stored or used for training | Check the vendor privacy policy for your plan |
GitHub Copilot: The AI Layer in Your Editor
Copilot works where you already work. It runs in VS Code, Visual Studio, JetBrains IDEs, Xcode, Eclipse, Neovim, and Zed. It also works in the terminal, on the web, on mobile, and in Slack and Teams. You do not switch editors to use it.
The feature set covers the full workflow. Agent mode plans and edits across files. Code review checks pull requests. Copilot in the cloud takes an assigned task and returns a pull request. Custom instructions, prompt files, and MCP server support are included. Copilot can also delegate work to third-party coding agents such as Claude and OpenAI Codex.
Pricing is the most complex of the three. GitHub's own plans page lists Free at $0, Pro at $10 per user per month, Pro+ at $39, and Max at $100. The Free plan allows 2,000 completions a month and limited chat and agent use. For organizations, Copilot Business costs $19 per granted seat per month, and Copilot Enterprise costs $39 per granted seat per month.
Since June 2026, Copilot bills agent work in GitHub AI Credits. One credit equals $0.01. Pro includes $15 of usage a month, Pro+ includes $70, and Max includes $200. Code completions stay unlimited on paid plans and use no credits. That detail matters. The sticker price is the floor, not the ceiling, for heavy agent use.
Copilot suits teams that live on GitHub. The pull request flow, the org controls, and the IP indemnity on Business and Enterprise plans fit companies with compliance needs. The weakness is billing complexity. You must watch credit use, not just the seat price.
Cursor: The AI-First Editor
Cursor is a full editor, forked from VS Code, with AI at its center. Tab completions, chat, and the Agent work as one system. Plan Mode is its standout feature. On a big job, the agent researches, asks questions, and writes an editable plan for you to approve before it changes a line.
Cursor's pricing page, checked on 7 November 2026, lists Free at $0, Plus at $8 a month, Premium at $30, Super at $100, and Ultra at $200. Teams starts at $30 per user a month, and Enterprise is custom priced. Usage pools refresh weekly. Prices exclude taxes.
Read the plan names with care. Plus covers Grok models only. It has no cloud agents, no Bugbot code reviews, and no third-party models. Premium adds four times the Plus usage, cloud agents and automations, Bugbot reviews, and Claude, GPT, and Gemini at their API list prices. Those third-party models bill separately, on top of the $30. A Premium user who leans on Claude pays $30 plus model costs.
Older guides still list a $20 Pro plan for Cursor. That plan no longer appears on the pricing page. The current ladder is Free, Plus, Premium, Super, and Ultra. Check the live page before you buy, because Cursor has changed its plans more than once.
Cursor suits developers who want the agent to drive. Plan Mode, multi-file edits, test runs, and fixes in one loop make it strong for feature work. The weakness is the model trap. The cheap plan is Grok-only, and the models most developers want cost extra.
Devin Desktop, Formerly Codeium and Windsurf: The Agent-Native Editor
Devin Desktop has the messiest history of the three. The company began as Codeium, a free code completion tool. It launched the Windsurf editor in late 2024. Cognition, the company behind the Devin coding agent, acquired Windsurf in 2025. In 2026, Cognition folded the editor into its own brand as Devin Desktop. The Windsurf site now redirects to Devin's site. Cognition states that existing Windsurf plans, pricing, extensions, and settings carried over unchanged.
The editor is a VS Code fork with the Cascade agent built in. Cascade edits across files, runs terminal commands, and iterates on its own work. The Free plan includes unlimited Tab completions and unlimited inline edits, with a light quota for agent work and limited model availability.
Pricing comes from devin.ai/pricing, checked on 7 November 2026. Free costs $0. Pro costs $20 a month and adds increased quotas, full model availability, free use of the SWE-2 model, and access to cloud agents through Devin Cloud. Extra usage bills at API pricing. Max costs $200 a month with much higher quotas. Teams costs $80 a month for the team plan plus $40 a month per full developer seat. Enterprise is custom priced.
Devin Desktop suits developers who want a generous free tier for completions and a strong multi-file agent. Cascade is built for the refactor-and-fix loop. The weakness is the brand churn. Two renames in two years make long-term planning harder, and the Teams price is easy to misread: the $80 base fee sits on top of the per-seat price.
How to Choose for a Real Project
Ask five questions before you pay.
- Will you switch editors? If no, Copilot is the only option of the three. It lives in your current IDE.
- Do you need cloud agents? All three offer them, but only on paid plans. Copilot includes a cloud agent that opens pull requests. Cursor needs Premium. Devin Desktop needs Pro.
- Which models do you want? Copilot's model choice varies by plan. Cursor's Plus plan is Grok-only. Devin Desktop's Pro includes frontier models from several providers.
- What is your monthly ceiling? Copilot Pro is $10, but credits add up. Cursor Premium is $30, plus API costs for third-party models. Devin Desktop Pro is a flat $20 with extra usage at API pricing.
- Do you need team controls? Copilot Business and Enterprise add policy management, usage metrics, and IP indemnity. Cursor Teams adds central billing and SSO. Devin Desktop Teams adds an admin dashboard and analytics.
Try the free tier first. Each tool offers one. A week of real tasks tells you more than any comparison table. Watch two things during the trial: how often the agent's edits need fixing, and what the usage meter says at the end of the week.
Bottom Line
Pick GitHub Copilot if you want AI inside the editor and workflow you already use, with the strongest GitHub and team controls. Pick Cursor if you will move to its editor for a deeper agent workflow, and you accept that the best models cost extra on top of the subscription. Pick Devin Desktop if you want the most generous free completions and a capable multi-file agent at a flat $20 a month. No tool wins on every axis. The right pick is the one whose limits you never hit.
