B2B SaaS Kit – open-source kit for building webapps with customer orgs

In plain words

B2B SaaS Kit is an open-source development tool for building web applications that serve customer organizations. It provides a foundation for developers to create multi-tenant SaaS platforms with built-in features for managing organizational customers. The kit is hosted on GitHub and targets software developers and teams building B2B applications who want to accelerate development by starting with a pre-built framework rather than constructing these common features from scratch.

  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…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I saw this [0] pretty cool thread by user revskill, and wanted a quicker way to search through it, but also to keep them all in one place so I can read them at my leisure whenever I get time. Right now is like 60 lines of Ruby using Nokogiri, but I will certainly look into it further down the line and improve the list. There's a cronjob checking the thread every 12 hours but I will eventually shut that down and it will become static after that. There are some really awesome blogs in there. I really recommend going through the list, it made my day. [0] "Could you share your personal blog…
