Terminal-based coding agent that edits your codebase and runs commands from natural-language requests.
Codebuff is a coding agent that runs in the terminal instead of an editor window: install it with npm, point it at a project, and describe a change in plain language for it to plan, edit files, and run commands or tests. It uses a multi-agent approach internally, with separate steps for file selection, planning, editing, and review, and it can call different underlying language models rather than being locked to one. The company was founded in San Francisco by James Grugett and went through Y Combinator's Fall 2024 batch. It also publishes Freebuff, a separate ad-supported free variant, alongside Codebuff's paid subscriptions.
Subscriptions run $100, $200, or $500 per month at increasing usage multiples; a pay-as-you-go option charges about 1 cent per credit with no subscription required.
Use tool ↗Codebuff is for developers who want an agent working directly in the terminal across an entire repository rather than inside a specific editor, with a multi-agent pipeline instead of a single model doing everything. The $100/month entry price is steep next to editor-integrated assistants, though the pay-as-you-go credit option gives a cheaper way to try it first.
Watch out: Individual files are sent to third-party model providers for processing depending on configuration; review that against your code's confidentiality requirements.
