    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…

    We just launched Croct Templates, a way to drop CMS-powered components into your app with a single command. It's like Shadcn, but for CMS, AB testing and personalization: * Built-in support for A/B testing, content editing, and dynamic logic * Works with existing projects (Next.js, React, etc.) * Supports community libraries via `npm://`, `shadcn-ui://`, etc. Example: ```bash npx croct@latest use shadcn-ui://block/pricing-page ``` Happy to answer any questions!

    Hey Hackers, Webstudio is an Open Source alternative to Webflow, and we just launched Webstudio CMS! We took an unusual approach to CMS because we wanted to prioritize maximum scalability, performance, and flexibility. So technically there is no CMS, but instead you can integrate with any headless CMS and its live! Go try it out! Here is a deep-dive using it with Hygraph https://www.youtube.com/watch?v=QC6Y7BHduLw To celebrate the launch we are giving away 3 Month of Pro account for free (expires in 24h): HACKERNEWS

    We’re Francis and Pierre, and we're excited to share Lightpanda (https://lightpanda.io), an open-source headless browser we’ve been building for the past 2 years from scratch in Zig (not dependent on Chromium or Firefox). It’s a faster and lighter alternative for headless operations without any graphical rendering. Why start over? We’ve worked a lot with Chrome headless at our previous company, scraping millions of web pages per day. While it’s powerful, it’s also heavy on CPU and memory usage. For scraping at scale, building AI agents, or automating websites, the overheads are…

    In a nutshell: 1. You log in with your GitHub account. 2. You select the GitHub repo where your site/app is at (whether it's Next.js, 11ty, Hugo, Nuxt... as long as you're using flat files for content). 3. You add a single config file to your repo to define the content types and other settings (e.g. media folder). 4. Congrats: you now have a user friendly CMS to manage content + media BUT all changes are still tracked like regular commits (under your account) on GitHub. I started using Jekyll around 2009 and over the course of the past 10+ years, I've helped build major sites and tiny…

    In the last few years I've been doing a lot of technical writing, both for my own programming blog and others, and I've noticed there is a lack of good tools for this kind of writing. Whether that was a programming blog post or documentation, I always had to move back an forth between different editors, and sometimes even other apps for content management and the actual content publication. A lot of copy-pasting, and wasted time. Based on this experience I decided to try and build a tool that could provide a good experience for this kind of content from writing to publishing. This (I call it…
