Gemini Vibe Code Hackathon – London

SpriteFlow is an AI-driven asset workflow builder for automation in video game asset creation.

Cache Cow is a VS Code extension that solves the critical, post-generation problem of Vibe Debugging (Problem Statement Three). While "vibe coding" with AI is fast, it often introduces hidden costs, latency, and quality issues that only appear in production. Cache Cow acts as an immediate, proactive quality gate, using Gemini to analyze code changes and infrastructure plans before they are committed. It transforms dry, technical analysis into energetic, motivational "Vibe Checks" delivered through a custom VS Code sidebar, making code analysis fun and constructive.

Codeminder is a hybrid LLM-based SAST (Static Application Security Testing) tool. It combines the speed and precision of traditional pattern-based scanning with the deep, semantic understanding of Large Language Models to provide a comprehensive and actionable security analysis.

This project (fine-tune.app) provides a full workflow for end-to-end fine-tuning of LLMs using user-uploaded data. The web UI and backend allow users to upload TXT, PDF, and DOCX files. The system automatically converts these files into high-quality JSONL training datasets, fine-tunes the Gemma 270M model, converts the result to GGUF, and deploys it to Ollama. The output model can then run fully locally, even on smaller devices and without an internet connection. This is particularly useful in domain-specific environments, privacy-sensitive settings, and cases where external APIs cannot be used.

This is a permanent “Museum of Vibe Coding”, built by Vibe Coding Collective, an international nonprofit. The goal is to ensure our community's creations no longer vanish. Our platform uses Gemini to crack open the 'black box' of every vibe coded app, extracting its tech and APIs so everyone can finally understand how their hobby project was built.

PatchGuard MCP is a lightweight server that automatically checks code generated by gemini for security issues, unsafe patterns, and lint problems. It creates a fast generate → scan → fix cycle that keeps rapid prototypes safer and more reliable during vibe coding.

A Vibe Ikigai agent that helps you plan and add some Vibe Wellness into your daily life

Developers often try multiple models manually, compare code quality by eye, then hope the one they picked works. This is slow and inconsistent. Anubis takes a single prompt and automatically runs it through multiple AI models. Each model generates a code candidate. Anubis then automatically evaluates each candidate using a scoring pipeline based on user-selected priorities. Each metric is weighted according to the priority level chosen by the user. Anubis produces a final weighted score for each code generated, ranks them, and surfaces the best one.

This project is an AI-powered simulation platform designed to automate and scale user experience (UX) testing. It solves a fundamental problem in product development: developer bias. Applications are often designed for the "happy path," failing to account for the diverse, unpredictable ways real users will interact with them. Our tool deploys "synthetic users"—AI agents with distinct personas—to simulate complex tasks and user journeys on your prototype. These agents "think aloud" as they navigate, systematically identifying friction points, usability flaws, and dead ends. The result is a fast, automated feedback loop. You receive an actionable report detailing exactly where the user experience breaks down and get concrete, AI-generated suggestions for refinement, allowing you to find and fix critical issues long before they reach your actual customers.

Our project is an AI-powered Business Insights Copilot that connects to a live SQL Server database and lets users ask natural-language questions without writing SQL.

Took the concept of the website Scratch which turns coding into 'lego blocks' as an intro to coding for system and implemented it with agent systems instead for various coding systems (e.g. UI, UX, backend, DB scheme etc).

In 2025, AI can generate ads, scripts, and videos, but small business owners often struggle to create professional content themselves. Vima AI bridges this gap by teaching users to make real videos with their phones, rather than generating artificial content. Users simply describe their business and select a style, and Vima instantly builds a complete videomaking plan. Each scene includes step-by-step guidance on positioning, angles, lighting, and common mistakes to avoid. For example, for a Shoreditch izakaya, Vima creates an Instagram Reel concept with aesthetic hooks, ASMR food shots, and warm lighting—all with simple instructions anyone can follow. The platform can also generate short video clips on demand. Vima completes each plan with platform-ready captions, hashtags, and a zero-cost budget guide. Rather than replacing creators, Vima empowers them to produce content that converts by teaching them how to create professionally.

Marionette, our project addresses both statement 1 and 3. Marionette is a cli tool that lives on top of claude code and other ai agents, which monitors both the user and the agent. The user is monitorred for poor prompts, and marionette encourages the user to write more detailed ones. The agent is monitored for sycophancy, and marionette automatically stops the agent, then forces the agent to rerun, but with less sycophancy.

As developers vibe coding complex agentic workflows, it's getting harder to understand what's happening at a high level.

We built a friendly, intent-aware maps web app using Google AI Studio for rapid iteration and code generation. Gemini models, grounded in Google Maps and Search, analyze geospatial data to provide tailored, context-aware suggestions. Today’s maps show one-size-fits-all lists, forcing manual filtering and slow decisions. Instead, we capture intent and use context to re-rank results so each person gets the right place for their immediate need. Enter Star Guide. It understands complex, shifting goals like “Wiped out” (close by), “Good Coffee” (decent quality), and “Meltdown” (quiet, changing station). Using Gemini, we skip generic lists and instantly re-rank local options based on how perfect they are for your situation right now, pulling signals from everything. We surface a single best match so you stop sorting through junk and make the right decision instantly.

A "Vibe-powered" AI CHEATER FINDER or you can call it interview engine that integrates multiple Google services—Gemini, Speech-to-Text, Text-to-Speech, and MediaPipe—to generate questions, conduct spoken interviews, and analyze each answer using voice, facial, and linguistic signals. The system produces a structured “truthfulness/confidence” score per answer by combining transcripts, timing, prosody, and real-time facial metrics. Essentially, it's a lie detector that can be used during work interviews or in romantic relationships Current apps rarely use more than text-only LLM calls and lack easy ways to integrate multiple Google SDKs into real, production-like experiences. This project provides a reusable template that shows how to orchestrate Gemini + audio + vision inside a single Vibe app.

Terra is a vibe-coding infra copilot that connects to your GitHub repo, analyzes the codebase, and proposes ready-to-use Terraform/Pulumi, Docker, and CI configurations for cloud providers like GCP, AWS, and Azure.
