Amp

Amp is an agentic coding tool that began life as a Sourcegraph project and was spun out as an independent company, Amp Inc., in December 2025, with Sourcegraph co-founders Quinn Slack and Beyang Liu leading it. It runs across four surfaces: a terminal CLI (installed via curl from ampcode.com), a web app, and native macOS and iOS apps, with a persistent conversation thread that follows the developer across devices.

The tool pairs frontier models with coding-specific machinery: specialist subagents like Oracle (second-opinion analysis) and Librarian (cross-repository research), cloud sandboxes called Orbs for parallel agent work, and workspace-level model routing so teams control which models and keys agents may use. Amp charges pass-through model pricing with no markup; the Hobby plan is free with bring-your-own keys, Individual is $20/month, and Teams keeps per-member plans with custom Enterprise pricing. Note that Amp retired its editor extensions in February 2026 and pivoted CLI-first, and its docs state it does not ask for tool approval by default, so teams should configure a policy plugin for guardrails.

Install the CLI with curl -fsSL https://ampcode.com/install.sh | bash, then run amp inside a project. Also available as a web app at ampcode.com and native macOS/iOS apps.
