Best Coding agents for GPT
16 quality-gated coding agents for GPT, compared on structured facts · pricing $5–$24 · 86% of known offer an API.
The ranking
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.
How we ranked these
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.

Editor’s pick
#1
Aider
Open-source AI pair programming in your terminal, free under Apache 2.0, built to run against 14 LLM providers
- #2
Cline
The open-source coding agent. Bring your own key. Runs in your editor, terminal, and as an SDK, with optional ClinePass for flat-rate open-model access.

Cursor
The AI-first code editor (a VS Code fork) with a coding agent that reads, plans and edits across your whole codebase. Free Hobby tier, Pro from $20/month.
Best forCompare GPT against Claude and Gemini in one editor
Cursor runs GPT alongside Claude and Gemini, selectable per request in the same in-editor agent — the easiest way to compare GPT against other frontier models without leaving your editor.
- #5
Devin
Devin is Cognition's autonomous coding agent: assign a task through Slack, CLI, or the web app, and it plans, edits, tests, and opens a pull request inside its own sandbox.
- #6
GitHub Copilot
GitHub's AI coding assistant with an issue-to-PR coding agent, multi-agent control plane (Claude Code + OpenAI Codex bundled), and broad IDE coverage. Free tier with 2,000 completions/month; Pro from $10/month.
Choose GitHub Copilot if you want GPT model choice inside GitHub's own reviewable, governed workflow.
- #7
Juggler
A free, open-source visual workbench for AI coding agents: each session is an editable Yjs tree, not a transcript. Single Go binary, no Electron, by the creator of JUCE.
- #8
Junie
JetBrains' own AI coding agent. Plans before it codes, drives the real IDE debugger, runs across the JetBrains IDE family plus a standalone CLI. Free 30-day Pro trial; Pro from $10/month.
- #9
Kilo Code
Open source AI coding agent for VS Code, JetBrains, CLI, and Cloud with 500+ models and no markup

OpenAI Codex CLI
OpenAI's open-source (Apache-2.0) terminal coding agent, bundled into ChatGPT plans from Free through Pro — Business seats are grandfathered-only.
Choose Codex CLI if you specifically want OpenAI's own terminal agent, bundled into a ChatGPT plan you may already pay for, rather than a model-agnostic tool that happens to support GPT.
- #11
OpenCode
A free, open-source (MIT) AI coding agent for the terminal, desktop and IDE, with 75+ model providers, built-in subscription login, and a tested model marketplace behind it.
- #12
OpenHands
Open source platform for cloud coding agents. Free local OSS, free Individual Cloud tier, self-hosted Enterprise with SSO and RBAC.
- #13
Warp
An open platform for automating development: an open-source terminal, a standalone coding agent, and cloud-agent factories that orchestrate Claude Code, Codex, Gemini CLI and Warp's own agent across your SDLC.
- #14
Windsurf (now Devin Desktop)
The agentic IDE that began as Codeium, then Windsurf, now Cognition’s Devin Desktop. An open command centre for local and cloud coding agents.
- #15
Zed
The open-source, GPU-native code editor built from scratch by Atom's creators — runs Claude Code, Codex and other agents via the Agent Client Protocol it created.
- #16
Zot
A free, MIT-licensed coding-agent harness in one Go binary. Branch any session from any past message, run 30+ model providers from one catalog, and DM the agent from Telegram.
Choose Zot if you want to run GPT for free through a self-hosted, open-source harness rather than a subscription product.
