DevinGemini CLIChoose Devin if you are teams that want to delegate well-scoped engineering tickets end-to-end. Choose Gemini CLI if you are developers who want frontier-agent capability with huge context at zero cost.
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; Gemini CLI runs generous free tier / gemini api 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.
Gemini CLI is Google's open-source AI agent for the terminal. Its standout traits are a 1M-token context window that can hold entire codebases and a free tier generous enough for real daily work with just a personal Google account. It supports MCP servers, Google Search grounding, and shell command execution in an agentic loop.
Whichever AI agent you choose, Standard Compute gives you unlimited LLM compute at one flat monthly price. No rate limits, no per-token billing.
