Agent Arena is a public leaderboard ranking developer tools by autonomous AI agent adoption.
Agent Arena runs an AI coding agent inside an isolated Docker container with a task prompt and a tool URL, then measures how autonomously the agent can discover documentation, install packages, write working code, and verify the result.
Providers are ranked across time, cost, errors, and interruptions, with all tool calls, errors, timing, and token usage recorded as deterministic session logs. Devtool builders use the rankings to compare adoption friction against peers and request detailed improvement reports.
