100 Hours Testing Claude Code vs Antigravity (honest results)
Summary
AI summaries can be incomplete or wrong. Verify anything important against the original video.
This video compares two leading AI coding agents, Claude Code and Google Antigravity, based on 100 hours of testing across various development tasks.
In this hands-on evaluation, the creator tests Claude Code and Google Antigravity to determine which agentic coding platform offers better performance for developers. The review covers the fundamental differences in architecture—with Claude Code functioning as a terminal-first tool and Antigravity operating as a standalone IDE—along with their respective strengths, weaknesses, and pricing models. Using a series of real-world test cases, including building habit-tracking applications and generating research reports, the video provides a direct comparison of planning, code quality, UI design, and execution speed. Ultimately, the creator argues that while Claude Code delivers superior logic and configuration, Antigravity excels in speed and interface design, concluding that the best choice depends on the specific priorities of the user's workflow.
Verdict
Claude Code is generally superior for complex logic and deep configuration, while Antigravity offers a more visually polished and faster experience for web design tasks.
Pros
- Claude Code provides excellent logic and project-level configuration.
- Claude Code offers deep integration with existing terminal-based workflows. 2:04
- Antigravity features a faster, user-friendly interface design.
- Antigravity includes a robust, visually intuitive built-in browser agent. 2:30
- Both tools leverage powerful underlying AI models for significant productivity gains. 10:23
Cons
- Claude Code's token usage can become expensive and prone to caching issues. 10:40
- Antigravity's model quota can lead to restrictive lockouts for power users. 19:04
- Antigravity may exhibit 'mental model drift' on long-running complex projects. 8:39
- Both platforms are still actively evolving, leading to occasional UI bugs or loop issues. 12:32
