Amp

Amp is a coding agent built by the team behind Sourcegraph. It runs as a command-line tool and as an editor extension, takes a task in plain English, and works through the repo using search, file edits and shell commands. It picks models for you instead of asking you to choose one.

The pitch is a tight feedback loop for people who already work in a terminal. Threads can be shared with teammates, so a colleague can read exactly how the agent solved something. That is handy for reviews and for learning how others prompt it.

It is paid and usage-based, so it suits developers who use agents heavily and want a polished tool rather than a free experiment.
