Frontend devs hate waiting for backend APIs to be ready: So Raj Savaliya vibe coded an app that instantly generates mock data based on API schema, so you can keep building without waiting on the backend team.

Vibe coding isn't just for games anymore. 🚀 Founders are using it to build real SaaS MVPs in days, not months. AI is writing 90-100% of the code. Here are 7 top-tier examples (bookmark this thread for inspiration):

A new kind of analytics tool. @csallen vibe coded an app that turns your website into a city, so you can watch visitors walk from page to page in real time 😮 95% of the code was written by AI, using Cursor, Claude Sonnet 3.7, OpenAI's o1 pro, and Gemini 2.5 Pro.

A recipe site you can control with your voice: You can talk through recipes and ask questions while you cook, all without touching your screen 🙌 YC partner @t_blom vibe coded this in a couple weeks with Windsurf, Claude Code, Gemini 2.5 Pro, and OpenAI's voice mode API.

It’s hard to calculate whether SEO will be worth the time investment: So @ctwtn vibe coded a tool that estimates the revenue you can expect from your SEO efforts, plus how long it'll take you to see these returns.

A penetration testing tool: You put in your website URL, and it spins up a multi-agent AI swarm to test for security issues. It’s fully open source, and it took @Sim0Rachidi two days to vibe code it with AI.

An app to make content creation easier: @sebastianvolkis vibe coded a SaaS that scans trending news articles, picks the ones with the most viral potential, and generates short-form content. The MVP took 4 days. Then he launched with a webinar and sold £5.5k on the first day 🔥

An affiliate marketing platform: @efesopoulos vibe coded a cheaper way to invite affiliates and watch them sell your product for you.

An AI-powered form builder: Traditional online forms ask everyone the same questions, but @amrix_j vibe coded Chadform to adapt to each individual using AI.
