# Best Coding agents for GPT

> Source: https://theagentsindex.com/best/coding-agents/gpt (curated, quality-gated, re-verified)

16 of the 25 coding agents in this index qualify for GPT — every one a Published, quality-gated listing, not a scraped row.

Across the set: 12 of 14 with known API status (86%) expose a public API, paid plans span $5–$24, and 14 offer a free or freemium tier.

16 of 16 carry a fact-verification date; the freshest check is 2026-08-25.

Only one of these six is GPT by default and by vendor — OpenAI Codex CLI, bundled into every ChatGPT plan. The rest (Cursor, GitHub Copilot, Windsurf, Juggler, Zot) are model-agnostic tools where GPT is a selectable option alongside Claude and others, useful if you want to compare GPT's output against a different model without switching tools.

## Methodology

Assembled programmatically from the live index: every entry is a Published, quality-gated listing in Coding agents carrying the "GPT" tag, ranked by tier then name. The numbers (16 tools, 86% of known with an API, paid plans $5–$24) are computed from the structured facts on those listings — this page exists only because the underlying data clears the density gate.
