DevinRoo CodeChoose Devin if you are teams that want to delegate well-scoped engineering tickets end-to-end. Choose Roo Code if you are power users who want a deeply configurable VS Code agent and don't mind tuning it.
Editorially this matchup is a dead heat: each agent leads in 3 of our six categories. On price, Devin runs $20/mo entry + usage (acus) and is proprietary; Roo Code runs free (byo api key) and is open source.
Devin is Cognition's fully autonomous software engineer: give it a task in Slack, Linear, or the web IDE and it plans, writes code, runs tests, and opens a pull request in its own cloud sandbox — including several sessions in parallel. It shines on well-scoped, repetitive engineering work (migrations, test coverage, small features) and improved markedly through its 2.x releases, but it remains weaker on ambiguous, novel tasks, and ACU-based usage pricing means heavy use costs real money. Cognition also acquired Windsurf in 2025, folding its IDE technology into the same product family.
Roo Code began as a fork of Cline and grew into its own power-user favourite. Its signature feature is modes: switchable personas like Architect (plan), Code (build), and Debug (fix), plus fully custom modes with their own prompts and tool permissions. It supports auto-approval settings for hands-off runs, MCP servers, and any OpenAI-compatible provider. The trade-off for all that configurability is a steeper setup than Cline — and, like every BYO-key agent, your API bill scales with how hard you run it.
