I rewrote an inventory app 4 times over 5 years before releasing v1
I’ve been building for 5 years. I rewrote it 4 times (Blazor Server -> Blazor WASM + Asp backend -> React + Node -> Ruby on Rails - Ruby and Rails are both awesome btw.) and kept telling myself I was “improving the architecture” when I was really avoiding release. I also spun up a few side projects in that period and shipped none of them. This is the first one I finally pushed live. It’s Upzone, an inventory app for ecommerce warehouse teams: receiving, bin locations, pick/pack/ship workflows, and Shopify/Amazon/... sync. Built on Rails 8, which has been genuinely great…

YourNextStore – an open-source Shopify with Stripe as the back end2024 · github.com · ▲285We’re building Your Next Store, a modern, ultra-fast, open-source commerce in Next.js with Stripe as the backend - no DB required. Selling online is often more complex than it needs to be. Setting up a storefront with great performance can feel daunting and time-consuming. There are many plugins, libraries, etc - the choice can be overwhelming. Plus, in e-commerce, the backend and frontend are often written in different languages (e.g., PHP, Python, or Ruby for the backend). This increases the complexity and makes code management more challenging, especially for teams. After working in…
I open-sourced my Go and Next B2B SaaS Starter (deploy anywhere, MIT)Dec 2025 · github.com · ▲83Hi HN, I'm Mohammed, a technical founder who loves shipping and giving back to the community.

Both are fully Dockerized with separate containers. No Vercel. No Supabase. Deploy the whole thing on a $6 VPS, or split frontend and backend across different providers. You own the infrastructure. The problem I was solving: Every SaaS starter I evaluated had the same issue: they locked me into someone else's platform. Vercel for hosting.…

A NextJS boilerplate to automate all the boring stuff2023 · shipfa.st · ▲23Hey HN, I'm a solopreneur and I ship apps like a madman. 16 startups in the last 2 years. I realized I was doing the same thing over and over: set up DNS records, connect DB, listen to Stripe webhooks... So I built ShipFast for 2 reasons: 1. Save time and focus on what matters: building a business 2. Avoid headaches like emails ending in spam or waiting 3 days for Google to approve I hope this boilerplate will be as helpful to you as it is for me. Would love your feedback pls Marc
