Cursor: The AI-First IDE
Cursor represents a different philosophy entirely. The team built an IDE from scratch around AI. Every feature serves AI-enhanced development. The result feels cohesive and intentional. Developers either love this approach or prefer traditional tools.
Cursor Core Capabilities
The interface resembles VS Code deliberately. Cursor forked the VS Code codebase. This decision ensures compatibility and familiarity. However, AI integration goes much deeper. The Agent Mode understands your entire repository. It reads every file when making suggestions. Context awareness surpasses traditional autocomplete.
Composer Mode enables powerful workflows. You assign high-level tasks to the AI. The agent plans the implementation approach. It modifies multiple files simultaneously. Testing happens automatically through browser integration. The results appear as comprehensive artifacts. Screenshots show the working application. Implementation plans detail every step taken.
Tab completion in Cursor feels remarkably smart. The tool predicts not just the next line. It anticipates where you’ll edit next. Multi-line suggestions appear frequently. Auto-import functionality adds missing dependencies. TypeScript and Python developers particularly benefit.
Cursor Pricing Options
The free tier provides basic functionality. Limitations apply to advanced AI models. Pro plans cost $20 monthly. This includes $20 of frontier model usage. Unlimited tab completion comes standard. Ultra plans reach $200 monthly. Power users requiring heavy AI usage choose this tier.
Cursor Advantages

Artifacts provide transparent communication. Agents generate task lists automatically. Implementation plans show their thinking. Screen recordings prove functionality. You review these artifacts like code reviews. Comment directly on screenshots. Provide feedback on specific plan elements. The agent incorporates your input immediately.
Browser control enables end-to-end verification. Agents launch Chrome autonomously. They interact with your application UI. User flows get tested automatically. Errors surface before you review code. This catches issues traditional assistants miss. GitHub Copilot vs Cursor vs Antigravity testing shows this capability stands alone.
The Editor View functions like a standard IDE. Gemini 3 Pro powers intelligent autocomplete. Inline commands handle routine edits. You switch to this mode for hands-on work. The experience resembles enhanced VS Code.
Antigravity Pricing Model
The public preview costs nothing. Individual developers access full functionality free. Generous rate limits refresh every five hours. Power users rarely hit these limits. Team and Enterprise pricing comes later. This introductory period encourages experimentation.
Antigravity Strengths
Autonomous execution changes the development paradigm. You operate at a task-oriented level. Describe desired outcomes in natural language. Agents handle implementation details. Complex multi-step workflows complete without supervision. This productivity boost feels transformative.
Cross-platform support arrives immediately. MacOS, Windows, and Linux work perfectly. No platform-specific limitations exist. Model optionality includes Gemini 3 Pro, Claude Sonnet 4.5, and GPT-OSS. Choose the best model for each task.
The learning capability improves over time. Agents save useful code snippets. They remember successful patterns. Future tasks benefit from past work. This knowledge base grows organically.
Antigravity Challenges
Early adopters report occasional issues. Rate limiting happens during peak usage. “Model provider overload” errors occur sometimes. Response speed varies unpredictably. The tool remains in public preview. Polish and stability need improvement.
