Tool by Tool
GitHub Copilot sets the bar for completions and editor support. Cursor is an AI-native editor: select code and ask, edit across files, and let agents run tests and fix bugs. Continue.dev is open source and lets you plug in any model, including local Ollama—code never leaves your machine. Aider works in the terminal with native Git integration, great for scripted workflows. Cody excels at whole-codebase Q&A. Twinny runs fully offline. Tabby is a self-hosted completion service for teams. Tongyi Lingma and MarsCode are Chinese-friendly options with generous free tiers.
How to Choose
- Daily VS Code use → Copilot free tier or Lingma
- Strongest "AI does the work" → Cursor
- Privacy / local models → Continue.dev + Ollama, or Twinny
- Terminal + Git → Aider
- Large codebase → Cody
- Team intranet → Tabby
FAQ
Q: Is the free tier enough? A: Yes for personal projects; open-source tools have no quota at all, just setup cost. Q: Local or cloud models? A: Local is free/private/offline but weaker; cloud is stronger but metered. Hybrid: small tasks locally, complex tasks in the cloud. Q: Copilot and Cursor together? A: Possible, but enable completions in only one to avoid Tab conflicts. Q: Copyright risk of AI code? A: Still debated; follow company policy for enterprise code, and prefer local models for sensitive projects.
Note: Free limits and features change; check official sites.
