Budget:

Light = hobby or occasional use, Medium = a regular solo dev, Heavy = daily heavy use. Rough estimates from vendors' public pricing, checked 28 Oct 2026. Not exact — always check the vendor. Tools with unknown pricing are hidden when a budget is picked.

Plan-first workflow around the coding agent you already use (Claude Code, Codex, Cursor, Grok, Antigravity, Pi, OpenCode, Copilot): each change goes through Discuss, Research, Plan, Outline, Implement, Verify and Review. You approve the plan from diagrams and clickable mockups, the agent builds test-first, and a separate agent that didn't write the code reviews it. Runs locally on your own subscription. Launched on Product Hunt Nov 4 2026.
