TaglineOpen-source VS Code agent. Reads + writes + runs.Anthropic's CLI agent. Opus-powered, operates on your repo directly.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.

PricingFree (open source) + your API costsPart of Claude Pro/Max/Team plansToken-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 Pro
Best forVS Code users who want agentic coding without changing IDEs.Developers who want an agent, not autocomplete. Large refactors, tests, docs.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.
Strengths
  • Free extension for VS Code
  • Plan + Act modes
  • Model-agnostic (Claude, GPT, local)
  • Sees terminal output and iterates
  • Runs locally, edits your actual files
  • Strong on large codebases with 1M context
  • Great at multi-step tasks
  • 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
Weaknesses
  • Can burn tokens fast if not watched
  • Less polished than Cursor
  • Terminal-based — learning curve
  • Can't be used without Claude subscription
  • 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
Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.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.
