Amp

Overview

Amp is an agentic coding tool from Sourcegraph that runs autonomously across a repository: it reads code, runs tests and shell commands, and edits files to carry out tasks like fixing failing tests or clearing type errors. It works from a CLI, inside VS Code and compatible editors, Neovim and Zed, from the web to steer CLI threads remotely, and as a Slack bot for teams. Rather than fixing one model, Amp routes between frontier and fast models for what each is best at, offers modes from low through high and ultra, and can draw on a linked ChatGPT subscription for extended high-mode usage.

Best for developers and teams who want an agent-first coding workflow across the terminal, their editor and Slack.

Amp suits developers who are ready to work through an agent rather than alongside one, and Sourcegraph has committed to that reading of where coding is going hard enough to drop the alternative. Anyone who wants autocomplete first and an agent second is looking at the wrong tool. Billing follows consumed model usage rather than seats, which cuts both ways: an occasional user pays less than a flat seat price, a team that delegates heavily pays more and cannot forecast it from headcount. The spread across terminal, editor, web and Slack earns its keep where several people follow the same agent run; a solo developer who lives in one IDE gets less out of it.
