Seven serious contenders now define the AI coding agent market

• ▸Seven tools are now considered serious contenders: Claude Code, Google Antigravity, OpenAI Codex, Cursor, Kiro, GitHub Copilot and Windsurf
• ▸Each takes a different philosophical bet on autonomy, pricing and workflow integration
• ▸Developer forums increasingly judge tools by whether they preserve context over long sessions, not by demo polish
• ▸Verification of agent output is repeatedly cited as the real bottleneck, not raw model capability

What developers actually argue about

Recurring discussion themes on developer forums center on workflow fit: can a tool inspect a real codebase without wasting a session rediscovering its structure, and can a developer supervise it without feeling like they're fighting the harness.
