Comparing as AI Code Editors & IDEsCodeium vs Cursor
Codeium
Cursor
Core Differences
The fundamental difference between Codeium (Devin Desktop) and Cursor lies in their architectural approach to integrating AI. Codeium began as a highly successful plugin providing AI code completion across numerous existing IDEs, later evolving into a forked agentic IDE (Windsurf Editor, now Devin Desktop) to offer deeper, more integrated agentic capabilities. Its journey reflects a strategy of broad compatibility followed by a specialized, AI-native environment.
In contrast, Cursor was conceived and built from the ground up as an AI-native code editor, directly forking from VS Code to create an environment where AI agents are core to its design, not an add-on. This means Cursor's AI features, particularly its autonomous agents, are deeply interwoven into the editor's fabric, offering a more seamless and opinionated AI-first workflow from the outset. While both now offer agentic IDE experiences, Codeium's path was from 'AI-everywhere plugin' to 'AI-native IDE,' whereas Cursor's was 'AI-native IDE from day one.'

Editor's Take
Honest opinion from our review team
As a reviewer, I found that Codeium (Devin Desktop), especially in its earlier plugin incarnation, felt like an incredibly natural extension to my existing development workflow. The seamless, unlimited autocomplete was a game-changer, integrating effortlessly into my preferred IDEs without demanding a shift in how I worked. The transition to the Windsurf Editor and then Devin Desktop introduced a more opinionated, agentic environment, which, while powerful, felt like a step towards a new paradigm rather than just an enhancement. I appreciated its focus on speed and reliability.
Cursor, on the other hand, immediately felt like a reimagining of the IDE. From the moment I started using it, I sensed that AI was not just a feature, but the very core of the editor. Its agentic mode for multi-file changes and the ability to choose between various frontier models was incredibly compelling, pushing me to think differently about how I approached coding tasks. While the credit-based pricing sometimes made me cautious about extensive agent usage, the sheer power and flexibility of its autonomous capabilities were truly impressive, offering a glimpse into the future of AI-driven software development.
Detailed Comparison
Both Codeium (now Devin Desktop) and Cursor operate on a freemium model, but their approaches to value and usage differ significantly. Codeium's initial offering was groundbreaking: a truly unlimited free tier for individual developers, providing code completions, chat, and search without credit limits or expiry. This established a strong value proposition. Post-rebrand to Devin Desktop, the Free tier still offers unlimited Tab autocomplete but with a 'light agent quota.' Its Pro tier is priced at $20/month, similar to Cursor's, but the subsequent Max ($200/month) and Teams/Enterprise tiers introduce higher usage limits and advanced features like SSO and enhanced security. The core value of Codeium's free tier, historically, was its sheer generosity for fundamental AI assistance.
Cursor's Hobby plan is also free, requiring no credit card, but it comes with limited Agent requests and Tab completions, and access primarily to its Composer models. Its paid tiers (Pro at $20/month, Pro+ at $60/month, Ultra at $200/month) all include a credit pool for premium model usage. This credit-based system means heavy users of agents or frontier models might quickly exceed their base plan's included credits, leading to on-demand overage costs billed in arrears, which can be a point of friction. While Cursor offers choice, it monetizes that choice and heavy usage more directly through credits. For teams, Cursor's Standard ($40/user/month) and Premium tiers offer centralized billing and shared agents. In summary, Codeium's free tier historically offered unfettered access to core features, while Cursor's free tier is more of a limited trial for its advanced agentic capabilities, with a credit-based system for paid plans that requires careful usage monitoring.

AI Verdict
In the rapidly evolving landscape of AI-powered development tools, Codeium (now Devin Desktop) and Cursor stand out as formidable contenders, each approaching the integration of artificial intelligence into the coding workflow with distinct philosophies. Codeium, initially gaining traction for its unlimited free AI code completion across an impressive array of 70+ languages and 40+ IDEs, carved a niche by democratizing access to powerful AI assistance. Its evolution into the Windsurf Editor and subsequent rebranding to Devin Desktop under Cognition AI signifies a pivot towards a more holistic, agentic IDE experience, emphasizing flow-aware multi-file editing and terminal control through systems like Cascade (now integrated with Devin Local). Its strength lies in its broad accessibility and a robust enterprise offering with strong security and data governance. Codeium/Devin Desktop is ideal for developers seeking a powerful, integrated AI assistant that can scale from simple completions to complex agentic workflows within a familiar, yet enhanced, development environment. Its strong historical emphasis on free, high-quality completion made it a disruptor in the AI coding space.
Conversely, Cursor was built from the ground up as an AI-native code editor, forking from Visual Studio Code to deliver a deeply integrated AI experience rather than an add-on. Cursor's core strength lies in its autonomous AI agents capable of planning and executing multi-file changes, running tests, and even opening pull requests. It offers developers an unparalleled choice of frontier models (OpenAI, Anthropic, Google Gemini, xAI Grok) alongside its in-house Composer models, allowing for significant flexibility in AI capabilities. Cursor excels for developers who want to reimagine their coding workflow around AI, leveraging agents for parallel task execution and comprehensive code exploration. Its focus on agentic autonomy and a highly configurable AI backend makes it a powerful tool for those ready to delegate more complex development tasks to AI. While Codeium (Devin Desktop) offers a powerful agentic IDE, Cursor's native agent integration and model flexibility provide a uniquely AI-centric development paradigm.
Frequently Asked Questions
QWhat happened to Codeium and is it still available?
Codeium evolved into the Windsurf Editor and was subsequently acquired and rebranded as Devin Desktop under Cognition AI.
