Register entry · Coding agents · updated 26 Sept 2026

Amp

Amp is a coding agent originally built at Sourcegraph and run by the independent Amp Inc. since December 2025. It offers a terminal CLI, web and macOS/iOS apps, and 'orbs' (remote machines where agents run without supervision), plus a meta-agent called Puck, Slack integration and multi-model routing through a 'dial' of modes. Since 13 September 2026 it is free when users bring their own compute and model keys or subscriptions; paid individual and enterprise plans add hosted orb time. By default Amp does not ask for approval before running tools; control is via custom policy plugins.

What reviewers and users praise

  • Model routing and orchestration praised by practitioners (Alex Dunlop; HN)
  • Orbs / one-thread-one-VM workflow liked by several users (HN)
  • Very high shipping cadence (43 dated changelog entries in 90 days)

What they criticise

  • Cost is a recurring complaint (HN; r/AmpCode 'spending thousands a month')
  • Frequent removal of features users relied on (plan mode, VS Code integration, handoff) (r/AmpCode; HN)
  • No approval prompts by default; tool control requires writing a policy plugin (docs)

Trust & safety

Seven dimensions graded A–D from documented facts. Overall: B.

C

Permission model

Docs state 'By default, Amp does not ask for approval before running tools.' Tool control is via custom policy plugins (distributable workspace-wide); tool-level allow/reject/ask/delegate permission entries also exist. Remote orbs isolate agents on separate machines, but local runs auto-execute by default. source

B

Data access scope

Local agent operates with the user's access to the workspace; docs acknowledge exposure to untrusted repositories/MCP servers and recommend policy plugins or isolated environments. Enterprise adds IP allowlisting and access controls. source

B

Data storage

User and thread data stored on Google Cloud Platform in the US; thread data removed within 30 days of deletion; audit logs retained at least 30 days. source

A

Data retention & training

Neither Amp nor subprocessors train on user data unless the user explicitly opts in (Enterprise cannot enable training); deleted thread data removed within 30 days; provider agreements limit model-provider retention, with Minimal Data Retention agreements available. source

C

Incident history (24 months)

August 2025 disclosures by Johann Rehberger (Embrace The Red): arbitrary command execution via prompt injection (agent modifying its own configuration), invisible Unicode-tag prompt injection, and data exfiltration via image rendering; all reported fixed by Sourcegraph. No GHSA/CVE entries found for @sourcegraph/amp or @ampcode/cli. source

A

Compliance

Security page: 'Amp is SOC 2 Type II certified, and we perform annual pentesting of our entire stack.' source

B

Transparency

Closed source; detailed, frequently updated dated changelog/news page and public manual. source

    Most Claude Code users don't need to switch. Consider Amp if you specifically want automatic model switching, native remote-codebase search, or clearer parallel-agent runs.Alex Dunlop · 15 Jun 2026 · alexdunlop.com
