Real builds from real GDG chapters. Two hours, one pizza, one prototype. Search by name, narrow to a GDG group or a date range — or scroll until something makes you want to fork it.
A targeted rent freeze program for households earning 30–60% of Area Median Income, combined with landlord subsidies and aggressive affordable housing production. This two-pronged approach stabilizes existing tenants while addressing long-term supply constraints.
“how easy it was to use the google AI ecosystem”
AI Interviewer is a real-time, voice-enabled mock interview platform that helps software engineers master both algorithmic coding and system design interviews. Built for tech candidates seeking realistic practice without the hassle of scheduling, it pairs an interactive code editor and architectural whiteboard with customizable interviewer personas. Powered by the low-latency Gemini voice AI that dynamically probes edge cases mid-interview and delivers comprehensive performance breakdown after.
“One of our challenges was to stop Gemini from giving away solutions too early. What surprised us was how naturally it calibrated its guidance, offering subtle nudges while staying in character according to the selected persona, acting as a real interviewer.”
Twin Space Dodger is a retro-styled dual-ship space runner designed to test parallel motor control and split-brain reflexes. Players control two ships simultaneously across independent parallel lanes to dodge incoming asteroid storms. With zero shooting, custom Web Audio synthesis, desktop dual-keyboard mapping (WASD + Arrows/IJKL), and mobile landscape dual-thumb touch zones, difficulty ramps up smoothly after a 5-second per-lane warmup into full dual-sync chaos.
“I was surprised by how effectively the 5-second single-lane warmup trained players' left-and-right hand dexterity before launching them into dual-sector chaos. Fine-tuning the Web Audio synth and parallel collision detection made the retro arcade feel remarkably responsive and addictive.”
Habit tracking app
“How fast it builds”
An interactive digital mood jar app that transforms daily emotions into preserved, glowing memory notes. Users record their current state of mind to receive instant AI reflections, visual vibe tracking, and mood history visualization directly in the browser.
“I was surprised by how a simple visual UI transformation and lightweight client-side state could instantly make emotion-tracking feel so tactile, playful, and engaging.”
VibeGuard detects security issues with vibe coded apps.
“How quick we were able to build it.”
An interactive educational web platform about NASA and space exploration. It features detailed guides on solar system planets, space news, NASA's historical achievements, and user account management, all wrapped in an immersive space-themed design.
“I didn't expect how easy it would be to integrate interactive features like live chat and user ratings into a static space web guide. It made the whole site feel like a real live product”
AURADEX is an AI-powered desktop productivity application built with Electron and modern web technologies. It provides an interactive workspace with analytics, project management tools, and AI-assisted features in a single interface. The goal is to help users stay productive while managing projects efficiently.
“I expected the hardest part to be building the interface, but integrating multiple features into a smooth desktop experience was the bigger challenge. I also learned that small performance optimizations can significantly improve the user experience.”
I made a Yiruma themed piano teacher app with Kyoto river in the background, this app is trying to be a performance level piano teacher, it creates immersive experience with customized ambient. So you see the beauty in piano and music. You can drag the bar to replay and practice key paragraph. In addition, it helps guide beginner to navigate their fingers on keyboard with finger number hints. Also you can at the same time play spontaneous key stokes to jam it up and make it fun:)
“I'm surprised to learn how music is programmed, sound font api, midi, mxl all the technical parts of how music interacts with computer. Using adaptive fingering engine, extending to 88 keyboard, adding paddle to replicate resonance and reverb. Beautiful music gets technical and require human craftsmanship and iterations of refinement. With Antigravity, it is possible seeing this being built.”
“I assumed building a real-time kitchen assistant would require a complex video streaming pipeline and file uploads. I was amazed that sending raw webcam frames directly to Gemini 2.5 Flash achieved sub-second, structured feedback loops.”
Craft_Faces is a web based live AR mask-wearing application, where you can choose and wear your favorite mask by hand gesture, and snap a shot by voice!
“When I decided to implement hand gesture interactions, Antigravity presented two potential approaches: 2D mesh and 3D mesh, not just one method. It clearly explained how each method works, demonstrated the expected visual effects, and outlined the advantages and trade-offs of each option. This helped me make an informed technical decision. This is very helpful and the spec generation is detailed.”
Turn the random ingredients in your fridge into a custom recipe and a dreamy, AI-generated photo of the finished dish — all wrapped in a Y2K Dreamcore aesthetic that feels like downloading a rare program in 2003.
“How fast vibe-coding tools like Antigravity take a developer from 0 to 1. I was surprised by the level of awareness and detail it displayed after well-engineered prompts.”
