Puck – Open-source visual editor for React▲451
Hey hackers, OP here! I've been dipping in and out of this problem space for the last few years with many of my clients. Puck sits somewhere between an old-school WYSIWYG-powered CMS and headless one, allowing content teams to author content using real React components. Traditional CMS solutions were flexible but often resulted in page that completely broke the brand guidelines. Headless CMS solutions are a fantastic way of controlling brand by restricting UI changes to developers, but makes layout changes restrictive and slow as developers often need to get involved. Puck provides a visual…

Open SaaS 2.0▲438
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…

Dynamic headless CMS with built-in CDP, AB testing and personalization▲22
Hey HN, I'm a developer and long-time OSS contributor. Over the years, I've implemented tons of headless CMSs to give product and marketing teams more autonomy. But there's always been a gap with CMSs when it comes to user interfaces. I kept running into the same issues: poor developer experience, bad performance, no support for dynamic content, and needing vendors for AB testing or personalization, which just gets messy and expensive. Versioning? One change and things break or need manual fixes. Accessing your own data? Good luck unless you're ready to pay extra. So, I built a content API…
