TaglineOpen-source VS Code agent. Reads + writes + runs.Wire Cursor's full coding-agent runtime into your own apps, scripts, and CI/CD pipelines with a few lines of TypeScript.French alternative. Fast, European, privacy-focused.OpenAI's browser agent. Clicks and types on websites for you.

PricingFree (open source) + your API costsToken-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.Free + $15/mo ProIncluded with ChatGPT Pro $200/mo
Best forVS Code users who want agentic coding without changing IDEs.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.European users with data residency needs. Fans of open-weight models.Power users willing to pay $200/mo for a browser bot.
Strengths
  • Free extension for VS Code
  • Plan + Act modes
  • Model-agnostic (Claude, GPT, local)
  • Sees terminal output and iterates
  • 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
  • European data residency
  • Very fast responses
  • Open-weight Mistral models available
  • Good French/European languages
  • Actually uses websites — fills forms, clicks, checks out
  • Built into ChatGPT
  • Good for repetitive web tasks
Weaknesses
  • Can burn tokens fast if not watched
  • Less polished than Cursor
  • 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
  • Smaller capability gap vs frontier models
  • Less polished UX
  • Slow vs doing it yourself
  • Breaks on complex auth flows
  • $200/mo gate
Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.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 overall, A-tier if GDPR/data residency matters. Solid backup option.B-tier. Still early. Manus is more flexible for less money.
