# Best Coding agents for GPT

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

21 of the 28 coding agents in this index qualify for GPT. Every one is a researched, quality-gated listing, not a scraped row.

Across the set: paid plans span $5–$100, and 19 offer a free or freemium tier.

21 of 21 carry a fact-verification date; the freshest check is 2026-09-30.

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 this index: every entry is a researched, quality-gated listing in Coding agents carrying the "GPT" tag, ranked by tier then name. The numbers (21 tools, paid plans $5–$100) are computed from the structured facts on those listings. This page exists only because enough listings carry that tag to make the comparison worth reading.
