// EDITOR'S TAKE
Cline is the closest day-to-day replacement inside VS Code, with plan and act modes and your own API keys, and kilocode extends the same idea with orchestrator and architect roles for larger changes. Tabby is the one to run if the real requirement is inline completion on your own hardware with no code leaving the building, Aider suits terminal-first work tied to Git commits, and Zed asks you to change editors entirely.
