LogRocket February Power Rankings: Open-Source Breaks Into Top 5
Story
The February rankings reshuffled: Windsurf #1 (Arena Mode for side-by-side model comparison), Antigravity (Google) #2, Cursor #3 (8 async subagents + Multi-Agent Judging), Kimi Code NEW at #4 — the first open-source tool in the top 5 with 100-agent swarm capability backed by Kimi K2.5 (76.8% SWE-bench), and Claude Code #5 with CLI depth and native worktree isolation.
The three-tool workflow crystallizes: Cursor for in-editor velocity, Claude Code for planning/architecture/CLI, Windsurf for model comparison. The frontier coding models (Opus 4.6 80.8%, GPT-5.3-Codex 80.0%, Gemini 3.1 Pro 80.6%) are in a statistical tie on SWE-bench — tool choice now matters more than model choice.
