	GitHub Copilot B	OpenRouter S	Cline A	Claude Code S
Tagline	Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration.	One API, every model. Pay-as-you-go, no subscriptions.	Open-source VS Code agent. Reads + writes + runs.	Anthropic's CLI agent. Opus-powered, operates on your repo directly.
Category	coding	dev platform	coding	coding
Pricing	Free (limited) + $10/mo Pro + $19/mo Business	Pay per token — model-dependent	Free (open source) + your API costs	Part of Claude Pro/Max/Team plans
Best for	Teams with GitHub already. Devs who don't want to change IDEs.	Developers experimenting across models. Apps that want fallback logic.	VS Code users who want agentic coding without changing IDEs.	Developers who want an agent, not autocomplete. Large refactors, tests, docs.
Strengths	Great enterprise story Works in your existing IDE Chat + autocomplete	300+ models from one endpoint Automatic fallbacks between providers No subscription — just pay what you use	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
Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Slight markup over direct API Some provider features not exposed	Can burn tokens fast if not watched Less polished than Cursor	Terminal-based — learning curve Can't be used without Claude subscription
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for model-shopping. I use this for every prototype before committing.	A-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.
