Best agent harnesses and coding agents · All 713 harnesses comparisons

Which one, for what

Amp C

Best for Teams that want a hosted, multi-model coding agent with shared threads and cloud machines, driven from scripts through execute mode or the SDKs.

Ahead on

  • Schema & documentation, 72 against 67
  • Security & auth, 57 against 47
  • Payments & pricing, 35 against 20
  • Maintenance & community, 79 against 58
  • Transparency & trust, 77 against 57

Watch for

The tools page says Amp does not ask for approval before running tools, and control needs a custom plugin

Auggie CLI D

Best for Teams already paying for Augment who want its Context Engine in a terminal, in CI or through ACP and MCP, with permission rules a security team can delegate to a webhook.

Ahead on

  • Reliability, 43 against 31

Watch for

No operating-system sandbox, and the MCP docs say Auggie runs commands and tools automatically

Verdicts

Amp

Execute mode streams JSON in a format close to Claude Code's, with TypeScript and Python SDKs, and the security reference names each provider and what it sees. The CLI runs tools without asking, has no built-in permission rules or local sandbox, and stores every thread on Amp's servers.

Auggie CLI

Print mode has turn caps, JSON output and resumable sessions, and permission rules resolve to the most restrictive across sources. Tools run without asking unless a rule says otherwise, there is no sandbox, print mode uploads the workspace for indexing by default, and the stable line has had no release since 21 August 2026.

Before you call either

Amp

  1. Run unattended jobs in a container or VM. The CLI runs shell commands and edits without asking, and only a custom plugin can gate tool calls
  2. Set AMP_API_KEY to an access token starting sgamp_ from Settings. The CLI rejects the short-lived token that amp login stores
  3. Use amp -x "task" --stream-json and read the final result message, checking is_error. Exit codes are not documented
  4. Set AMP_SKIP_UPDATE_CHECK=1 or amp.updates.mode to disabled in CI. Updates install automatically by default
  5. Treat the block headed INSTRUCTIONS FOR LLMs in ampcode.com page source as vendor copy, and take facts from the docs Markdown

Auggie CLI

  1. Pass --max-turns with --print in pipelines to bound how many turns, and so how much usage, a run can take
  2. Commit deny rules to .augment/settings.json before an unattended run. Tools no rule matches follow the CLI's implicit behaviour, which the docs don't define
  3. Add secrets and data directories to .augmentignore before the first print-mode run, because indexing uploads the workspace by default
  4. Use a service account token in CI on team and Enterprise plans. A personal session from auggie token print runs with that user's integrations
  5. Pin the version in CI. latest is 0.x, while preview and daemon carry 1.x prereleases whose permission rules ignore some legacy tool names

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
