TaglineAnthropic's SDK for building your own agents on Claude.Wire Cursor's full coding-agent runtime into your own apps, scripts, and CI/CD pipelines with a few lines of TypeScript.OpenAI's image model. Built into ChatGPT Plus.OpenAI's browser agent. Clicks and types on websites for you.

PricingAPI usage + SDK is freeToken-based; requires Cursor plan (Pro from $20/mo). Composer 2 at $0.50/$2.50 per M tokens (in/out); fast variant $1.50/$7.50 per M tokens.Included with ChatGPT Plus $20/moIncluded with ChatGPT Pro $200/mo
Best forDevelopers building custom agents for their own company/product.Engineering teams who already use Cursor and want to embed its coding-agent runtime into CI/CD pipelines, backend services, or internal developer tools without building agent infrastructure from scratch.ChatGPT Plus users who want images without paying extra.Power users willing to pay $200/mo for a browser bot.
Strengths
  • Production-grade agent primitives
  • Built on Claude (best reasoning)
  • Full control — build exactly what you need
  • Same runtime as the Cursor IDE — no reinventing sandboxing, context management, or model routing
  • Three execution modes: local machine, Cursor cloud VMs (isolated per-agent), or self-hosted workers for air-gapped teams
  • Cloud agents are durable — keep running even if your laptop sleeps or connection drops, and can open PRs automatically on finish
  • Full harness included: codebase indexing, MCP servers, skills, hooks, and multi-agent delegation via subagents
  • Visible in Cursor's Agents Window — programmatic runs can be inspected or taken over manually in the IDE
  • Excellent prompt understanding
  • Built into ChatGPT — no extra subscription
  • Good at composition + concepts
  • Actually uses websites — fills forms, clicks, checks out
  • Built into ChatGPT
  • Good for repetitive web tasks
Weaknesses
  • Developer-only
  • You build the UI
  • TypeScript-only SDK — no official Python or other language bindings at launch
  • Public beta status means API surface and pricing can shift without much notice (Cursor has a track record of surprise pricing changes)
  • Cloud VM costs layer on top of subscription credits, making cost estimation non-trivial at scale
  • Aesthetic ceiling below Midjourney + Ideogram
  • Text rendering worse than Ideogram
  • No fine control
  • Slow vs doing it yourself
  • Breaks on complex auth flows
  • $200/mo gate
Kai's verdictS-tier for builders. The right primitives. What Kai is built on under the hood.If your team is already in the Cursor ecosystem, this is a genuinely compelling way to turn ad-hoc AI coding sessions into durable, automated workflows — but the beta label and Cursor's history with opaque pricing mean you'll want to set hard budget guardrails before going to production. (Verdict pending Phi's full review.)B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.B-tier. Still early. Manus is more flexible for less money.
