Real builds from real GDG chapters. Two hours, one pizza, one prototype. Filter by track or chapter — 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.

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.”
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”
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.”
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.”
For the spenders who dread checking their credit card statements at month's end. Buster is a financial tracker that brings awareness to your spending habits. Buster keeps you in check—catching that $6 coffee you buy every morning and highlights how your daily choices impact your financial picture. Stay accountable without the shame.
“For a first time gemini user it was fun to test the capabilities in a developer friendly environment. I think that in the ~45 minutes we had, I was able to build a fun MVP and demo that satisfied a big paint point in my life, and potentially others. Looking forward to bringing out the max potential out of Gemini and the Google tools as I try to bring this application to the App Store!”
