How to Choose the Right AI Coding Tool?
For Beginners
- 1. If you're just starting with AI coding, start with Cursor - friendly interface and easy to learn
- 2. For students, see the official pricing page for GitHub Copilot pricing
- 3. On a budget? Try Antigravity first (all models available to try). Pricing: see the official pricing page
For Professional Developers
- 1. For high-quality code generation, choose Claude Code - strong code understanding
- 2. For team collaboration, choose GitHub Copilot - mature ecosystem
- 3. For multimodal needs, consider Antigravity (the Gemini line)
QCode.cc currently supports Claude Code and Codex CLI. Cursor is not supported as it does not allow configuring third-party API endpoints.

2026 Q3 tool landscape refresh
Key recent changes: 1) Cursor 3 (04-02) turned the editor into a multi-agent console with Agents Window; SpaceX announced the $60B all-stock acquisition of Anysphere on 06-16 (SEC 8-K, expected to close in Q3, regulatory process underway). 2) Google Antigravity 2.0 (05-19) grew from an IDE into a five-surface agent platform; Gemini CLI was sunset on 06-18 and replaced by agy. 3) Tool pricing: Cursor Pro / Claude Pro / Google AI Pro / Windsurf Pro — pricing: see the official pricing page. 4) The open-source plugin line (Cline et al.) has become the second route beyond subscriptions thanks to BYOK + custom endpoints. Match tools to scenarios: full IDE suite → Cursor 3 or Antigravity; long terminal tasks → Claude Code / Codex; need your own endpoint → Cline.
