Hi HN, I'm Mohammed, a technical founder who loves shipping and giving back to the community. I'm open-sourcing the full-stack engine that powers my B2B product, apflow.co. What it is: A production B2B starter with a Go backend and Next.js frontend. 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.…

Hi, Piotr here I was collecting nice open-source companies for quite some time now. Mostly to take some inspiration and learn from their code. Last week, I though it would be fun to learn this Astro thing everyone's talking about. So I thought building a directory website out of this collection was pretty good idea. After 2 days of building, OpenAlternative was born. It's a community driven list of open source alternatives to proprietary software and applications. Enjoy and thank you for your support!

Hey HN! We launched sliplane.io, where deploying Docker containers is super simple and wallet-friendly. With our Pay-per-Server approach, you can host as many containers as you want on each server at a set price - no huge surprise bills, just straightforward Docker hosting. You simply connect your Github repository and we do the rest that you expect from a PaaS, SSL by default, automatic deployments, backups of your storage etc. Pricing starts at 9€/month for 2vCPU, 2GB RAM, 40 GB Disk, 2 TB Egress. Cheers, Jonas

Hey HN, we're launching Outpost, an open-source, self-hostable component designed to handle outbound event delivery for SaaS/API platforms. If you're building a platform, you eventually need to send events to your users (think payment success, resource updates, workflow changes). Implementing this reliably—handling retries, monitoring, scaling, providing a decent dev experience for consumers, and managing tenants—becomes a significant, recurring engineering task that distracts from core product development. We built Outpost to offload that complexity. Outpost delivers events via…

Hi! I am sharing this because it may be useful to others. I created a simple Docker image that lets you easily expose a web app running locally on your dev machine to the Internet, via a proxy server. It is a self hosted alternative to something like Ngrok, which is a paid service if you use custom domains. A small server is cheaper than Ngrok (I use Hetzner Cloud and the cheapest server costs me 3€ per month). I use this method in particular to test HTTP verification with Let's Encrypt for a SaaS app running on my Mac. Hope this is useful :) Code:…
