Pricing modelFreemium Open source
PricingFree: A personal sandbox with chat, build and bots, every agent CLI, and integrations included, no credits. Pro: $50 per user per month (early-access promotional pricing; standard price is $200), billed monthly, with unlimited seats, team sharing, your own cloud or dedicated machine, $10 of AQ credi Not given
Key features
  • Chat with agents about code, data and tools with answers as tables, charts and pages
  • Isolated worktrees per task with live preview and pull request review
  • Standing bots that wake on schedule or event with monthly spend caps
  • Crews with independent agent review
  • Live multiplayer terminals and previews shared with the team
  • Support for 11 coding agents: Claude Code, Codex, Cursor, Kimi Code, Grok, Antigravity, Devin, Muse Code, OpenCode, Command Code and Pi
  • Integrations with Linear, GitHub, Slack, Gmail, Google Calendar, Granola, Sentry, Mercury, Vanta and Stripe
  • Memory shared across agents searchable by the whole team
  • API, webhooks and MCP server for automation and third-party tools
  • Run on private AQ-managed sandbox, dedicated machine, or your own cloud infrastructure
  • Configure plugins, skills, MCP servers, and hooks in a single harness.yaml file
  • Observatory: monitor every session, tool call, and minute of activity
  • Memory: persistent knowledge graph for AI orientation
  • Comparator: run prompts across Claude Code, Cursor, and Copilot side by side
  • Import existing configs from multiple AI coding tools automatically
  • Share complete setup via single file with teammates
  • Harness Parity: verify all connected AI tools end up with identical configuration
  • Cross-harness compatibility table showing actual tool capabilities
What makes it different
  • No setup required: start free in a sandbox AQ creates, or move to your own cloud with one click
  • Keep subscriptions unmetered: your team's Claude, OpenAI and Cursor accounts are never marked up
  • Shared live workspace: the whole team sees the same terminal and preview, not a replay
  • Independent agent review: a second agent reviews code without seeing the builder's work
  • All agents in one place: Claude Code, Codex, Cursor and 8 more, each signed in with your accounts
  • Import-first approach: reads existing configs from all your tools and converges them before you write YAML
  • No marketing gloss: capability table generated at build time from actual adapter code, not hand-maintained
  • Portable across tools: single harness.yaml travels with you to every machine and tool
  • Open source and free: no cost beyond existing Claude subscription
  • Based on open specification: Harness Protocol is vendor-neutral and JSON Schema validated
