Which to pick if…

  • If the job is “An agent inside stock VS Code”

    Pick Cline (7.6). Open source and free. Trade-off: Setup means API keys and a model choice.

  • If the job is “A terminal agent on OpenAI models”

    Pick Codex CLI (7.5). The CLI is open source. Trade-off: Model access and plan limits are separate from the CLI itself.

  • If the job is “A fast editor when VS Code feels heavy”

    Pick Zed (7.5). The editor is free and open source. Trade-off: Extension coverage is not VS Code's.

  • If the job is “Git-native pair programming from the terminal”

    Pick Aider (7.4). Open source and free. Trade-off: You bring a key, a model, and your own taste about the diff.

  • If the job is “A local open-source terminal agent”

    Pick OpenCode (7.4). Open source. Trade-off: Younger and less of a default than Claude Code or Aider.

  • If the job is “A terminal agent on Gemini”

    Pick Gemini CLI (7.2). Open source. Trade-off: Tied to Google's model access and quotas.

  • If the job is “Owning the extension and choosing the model”

    Pick Continue (7.1). Open source, so you can read and change it. Trade-off: You assemble the model, keys, and config yourself.
