Core Differences
The fundamental difference between Cursor and Codeium (Devin Desktop) lies in their origin and philosophical approach to AI integration.
- Cursor was built from the ground up as an AI-native code editor, a fork of VS Code, with the core design principle of embedding AI agents directly into the IDE's fabric. It emphasizes giving developers a choice of frontier models and leveraging autonomous cloud agents for parallel, end-to-end task execution, making AI an intrinsic part of the development lifecycle.
- Codeium (Devin Desktop), conversely, evolved from a highly successful, free AI code completion and chat plugin that supported 40+ IDEs. Its journey to an agentic IDE (Windsurf, now Devin Desktop) was a strategic pivot, initially leveraging its own proprietary models and now integrating with Cognition AI's Devin ecosystem. Its strength historically lay in broad compatibility and free, unlimited completion, before transitioning to a more comprehensive agentic offering, now focused on the Devin Local system.

Editor's Take
Honest opinion from our review team
As an editor, I found that Cursor delivers a remarkably cohesive AI-native development experience. The moment you open it, it feels like VS Code, but with an AI brain fully integrated. I particularly appreciated the ability to choose between various frontier models; it felt empowering to pick the right tool for the job. The agentic workflows, especially for multi-file changes and the promise of cloud agents, are incredibly powerful, though I did find myself mindful of the credit usage with premium models. It encourages a new way of thinking about coding, almost like pair programming with an incredibly smart, multi-talented assistant.
Codeium (now Devin Desktop), on the other hand, had a different 'feel.' Its original plugin form was incredibly seamless and became an indispensable part of my existing IDE workflow for sheer, unlimited completion. The transition to an agentic IDE and the subsequent rebrand to Devin Desktop has been a bit jarring, creating some initial confusion. However, the underlying agentic capabilities (now Devin Local) are robust, and the commitment to enterprise-grade security is commendable. For me, the 'feel' shifted from a universally compatible, free superpower to a more opinionated, agent-focused IDE, albeit one backed by significant AI research. If you're invested in the broader Devin ecosystem, it's a natural fit, but the frequent changes require some adaptation.
Detailed Comparison
Both Cursor and Codeium (Devin Desktop) operate on a freemium model, but their pricing structures and value propositions diverge.
- Cursor's Hobby plan is free, offering limited agent requests and tab completions, primarily with its Composer models. Paid tiers (Pro at $20/month, Pro+ at $60/month, Ultra at $200/month) significantly increase usage limits and provide access to premium frontier models, often via a credit pool. The credit-based billing for premium models means heavy agent usage or reliance on top-tier LLMs can quickly exceed included credits, leading to potentially unpredictable overage costs billed in arrears. For teams, plans start at $40/user/month, adding enterprise features like shared agents and SSO, with annual billing offering a ~20% discount. The value here is in the depth of AI integration and model choice, but users must carefully monitor their consumption.
- Codeium's (Devin Desktop) free tier for individuals still boasts unlimited AI code completion, a significant value proposition that was a core differentiator historically, though it now includes a 'light agent quota.' This makes it excellent for developers primarily seeking robust, free code completion. Paid tiers, now aligned with Cognition's Devin plan structure, start at Pro ($20/month), Max ($200/month), and Teams ($80/month + $40/seat). While the Pro tier matches Cursor's at $20/month, Codeium's pricing has seen multiple increases and rebranding (from $15 to $20 for Pro), which can create user uncertainty. The value for paid tiers lies in full model access, standard agent quotas, and enterprise-grade security features like on-premises deployment and zero data retention, which are crucial for highly secure environments. The free tier remains a strong entry point, but the agentic power is reserved for paid plans.
