I vibecoded a 35k LoC recipe app
Over the last 2-3 weeks, I vibecoded the recipe app that I always wished existed - recipeninja.ai . It now includes a fully interactive voice assistant so you don't need to get your dirty hands over your new iPad when you're cooking. Background: I’m a startup founder turned investor. I taught myself (bad) PHP in 2000, and picked up Ruby on Rails in 2011. I’d guess 2015 was the last time I wrote a line of Ruby professionally. Last month, I decided to use Windsurf to build a Rails 8 API backend and React front-end app, using OpenAI's realtime API for voice-to-voice responses. Over the last few…
I vibecoded a 35k LoC recipe app launched on April 2, 2025 with 126 votes, #364 of 7,818 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
RecipeNinja.ai is a recipe application built with a Rails 8 backend and React frontend that features a fully interactive voice assistant powered by OpenAI's realtime API. Users can interact with the app entirely through voice commands without needing to use their hands while cooking, making it suitable for kitchen use on tablets or other devices. The voice assistant uses function-calling to navigate the application in real-time as users chat, allowing hands-free browsing and recipe interaction.

An open source framework for voice assistants2024 · github.com · ▲346I've been obsessed for the past ~year with the possibilities of talking to LLMs. I built a bunch of one-off prototypes, shared code on X, started a Meetup group in SF, and co-hosted a big hackathon. It turns out that there are a few low-level problems that everybody building conversational/real-time AI needs to solve on the way to building/shipping something that works well: low-latency media transport, echo cancellation, voice activity detection, phrase endpointing, pipelining data between models/services, handling voice interruptions, swapping out different…
Chefiniti - Smart Recipe Creator2025 · chefiniti.app · ▲17Hi HN, Happy to share the project I've been vibe-coding on for past few months. The Problem: Like many people, I often found myself staring at a fridge full of random ingredients (some about to expire) with no idea what to cook. I was tired of food waste and the repetitive cycle of making the same few meals. I wanted a way to creatively use what I already had. The Solution: So, I decided to build Chefiniti. It's an iOS app that acts as a personal AI chef. The core idea is to turn your available food into delicious, custom recipes. I know there are already tons of apps like it but this one is…

Startkit.ai – Boilerplate for building products with AI2024 · startkit.ai · ▲25Hey HN! I've been serially building AI projects for over a year, and building node + js SaaS products for over 10 years with my partner. We decided to combine everything we know about AI with our node best-practices into a code boilerplate and see if it can help anyone else! We've had a bunch of positive feedback already from early-users, and at least two SaaS products being developed right now with StartKit.AI as their base. Here's what you get! → Pre-built modules for all common AI tasks: - Chat! Everything to build a ChatGPT clone or your own chatbot. With best-practice implementations of…

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
