|---|---|---|---|
| What it is | The incumbent, embedded in VS Code, JetBrains, Visual Studio, Xcode, Neovim and github.com, plus a terminal agent called Copilot CLI and a cloud coding agent that opens pull requests. Model choice spans Claude Haiku, Sonnet and Opus, GPT-5 mini and Gemini, selectable per request. | The original terminal AI pair programmer, Apache-2.0 with roughly 48k stars and still actively developed. It builds a repo map of your codebase, edits files in place, runs linters and tests, and auto-commits every change with a written message. Works with almost any LLM, including local models. | An Apache-2.0 autonomous coding agent with roughly 64k GitHub stars, shipping as a VS Code and JetBrains extension, a CLI, an SDK and a web kanban board. Its Plan/Act split makes the agent draft an approach before touching files, and every diff and terminal command needs approval by default. |

| Cost tier | mixed | free | free |
| Pricing | Free (2,000 completions) · $10/mo Pro · $39/mo Pro+ · $100/mo Max · Business and Enterprise | Free and open source (Apache 2.0) · BYO API key | Free and open source (Apache 2.0) · BYO key or pay-as-you-go credits |
| Why builders pick it | The safe institutional choice: your employer probably already pays for it, it works in the IDE you already use, and the free tier with 2,000 completions a month is the lowest-friction on-ramp in the whole category. | Git-native discipline: every AI edit lands as its own commit, so git diff and git revert are your undo button. It is the cheapest serious option because you pay only raw API tokens, and it scripts cleanly into CI. | The transparency pick: you see every diff and every command before it runs, and you pay providers directly with no markup. Works with Claude, GPT, Gemini, Ollama and 200+ models via OpenRouter, so nothing is locked in. |
| Watch out for | Premium requests are the real currency — each agent prompt eats quota, and Pro's $15 of monthly credits goes quickly on Opus-class models. Copilot CLI needs an active subscription and can be disabled by org admins. | No GUI and no MCP-style tool ecosystem; the interaction model is chat plus file mentions, which feels dated next to fully autonomous agents. | BYO-key means costs are unbounded and easy to underestimate — one long agent session on a frontier model can run to several dollars. |
| How to wire it up | npm install -g @github/copilot | python -m pip install aider-install && aider-install | Install 'Cline' from the VS Code marketplace |
