AI builder & coding tools

Find the right AI builder for how you actually work

Find the right AI builder for how you actually work — app builders, coding editors, terminal agents, and agent workspaces compared on control, hosting, code ownership, and price. Model APIs live on the AI models catalog; products that wrap models into coding experiences live here.

This hub compares products that wrap models into coding and building experiences — not raw model APIs. Browser builders such as Lovable and Base44 sit beside repo-first tools such as Cursor and Claude Code. Compare AI code review for GitHub App reviewers such as CodeRabbit (paid link), Qodo, Greptile, and Gitar. Compare models for the APIs behind them, or New models for what launched recently.

Common questions

Questions about coding harnesses

Answered from the verified figures on this page rather than general guidance.

What is an AI coding harness?

A harness is the product around the model: where it runs (editor, terminal, browser), how it bills, and how much autonomy it has. The model API is a separate catalog.

Does the catalog include Cursor?

Yes. Cursor is compared with Claude Code, GitHub Copilot, Codex, Devin Desktop, and other harnesses, with a dated setup guide at /ai-harnesses/setup/cursor.

Is the seat price the whole bill?

Usually not. Agent-heavy work can exhaust included usage and switch to on-demand. Each profile’s watch-out states the current pool and promo caveats.

Where should I start if I am new?

Open the setup guide for the harness you chose, turn on the privacy/training controls before a sensitive repo, and run the first task in a read-only or Ask mode.
