|---|---|---|---|
| What it is | An MIT-licensed terminal agent from Anomaly, and the breakout open-source success of the era with well over 150k GitHub stars. It runs in the terminal, a desktop app or an IDE extension, drives 75+ providers through Models.dev, uses LSP for real language awareness, and runs several sessions in parallel. | 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 | free | free | free |
| Pricing | Free and open source · BYO key · optional Zen credits | 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 vendor-neutral default when you want Claude Code ergonomics without the vendor. Shareable session links make debugging an agent run collaborative, and it has become the harness other products build on, including Roomote. | 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 | Optional OpenCode Zen credits start at a $20 top-up; the agent itself is free but you are always paying some model provider. | 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 | curl -fsSL https://opencode.ai/install | bash | python -m pip install aider-install && aider-install | Install 'Cline' from the VS Code marketplace |

Prefer the free tier when no budget was stated, and say what the ceiling is. 2. Read the full dossier before integrating. 3. Fetch /api/public/models before writing any AI model ID.
