I noticed several friends talking about Google's new open source Gemini CLI on my social feeds, so I figured I'd take it for a spin and document the experience. No script, no preparation - just installing it and seeing what happens when I ask it to build some web apps.
First I built a Sudoku game, then attempted to build Tetris (with some interesting rotation behavior), and threw together a simple todo app. The interface output was clean, the interaction mode is an evolution from the AI coding assistants I've used previously, and the minor rough edges you'd expect from a launch-day product.
Note: this was recorded during what seemed like heavy server load, so performance / wait times were inconsistent. The self-correction behavior when things break is actually pretty interesting from a UX standpoint -- I have to give credit for how transparent it's approach is: you always know what it's doing and/or thinking in the moment.
If you're evaluating AI coding tools or just curious about Google's approach, this might be useful. I'm planning to test it with more complex scenarios and actual project files next.
What I tested:
- Installation via npm
- Single-file web app generation
- Error handling and self-correction
- Web search integration
- General usability
