    I launched Open SaaS about a year and a half ago and surprisingly it’s become one of the most popular free SaaS boilerplate starters on github (https://github.com/wasp/open-saas). After 2 years of work total, I’m pleased to launch what I’m calling “Open SaaS v2.0”. Here’s a breakdown of all the features and updates I’ve made to it over time: * New Big, Shiny Things for v2.0 * - Complete redesign with Shadcn UI for a modern and consistent look (themeability coming soon...). - Script that autogenerates an LLM-friendly version of the documentation…

    We strongly believe working on open source software should be a viable source of income for many more developers. Unfortunately, the following barriers limit the extent of open source funding: - Only a small fraction of open source projects are funded, and most money goes to a few notable projects. - Each project has to market is self to get significant funding. - Large corporate donations provide the bulk of the funding, making it unreliable and unattainable for many. - Finding and supporting each of your dependencies is a cumbersome task. Which ones, how much, and on which platforms? So we…

    Hey! I recently got laid off from my comfy engineering manager job and decided to go full-time indie hacking. I’ve built around 5 side projects in the last 3 years and have much experience in launching and getting sales. However, at this time, I need a way to do it faster as I am bleeding money. It usually took me more than 3-6 weeks from idea to shipping the MVP to the first users as I was busy setting up the typical flows like payments, analytics, error tracking, and whatnot. Usually, when everything was ready, I was not motivated to launch. I built Cascade to solve this problem! The idea…
