    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…

    Hi HN! My name is Nick and this is my fun side project. Please lay it on me. HN can think of Tips.io as a cracked out Tailwind Playground that has page management and amazing AI integration. There are a few core ideas: 1) The HTML is the CMS There are no fields or restrictions. Just hover, click, and start tweaking any HTML. Also, certain elements you click will have special easy edit abilities: - auto creates an uploader, stock photo picker (or HTML) - auto creates an uploader, stock video picker (or HTML) - auto creates a big icon picker (or HTML) - auto creates a WYSIWYG Editor (or HTML)…

    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…

    Hi HN, We are the devs behind VibeShift. We have been building this MCP server to put AI coding assistants in an automatic feedback loop. They code, test, debug, fix everything until we have a fully working, secure code. It tests like a real user, copies network/console and logical errors to give them back to cursor. (1 min demo - https://www.youtube.com/watch?v=bN_RgQGa8B0) We felt this was the natural next step for AI coding assistants. And with new asynchronous assistants like codex, having a plug & play tester makes sure you don't have to spend time debugging and…

    Viberia▲146

    Hey HN, This is my take on the agent harness. Everything on an isometric map. Agents are grouped into "buildings" that run in a sequence or a loop; e.g., the CodeForge has an agent that writes a PRD, another one that implements, and a third that reviews. Everything is customizable, you build your own buildings/teams however you want. It's a Tauri app, really light (about 8x less energy than the closest competitor I benchmarked, so it actually runs from a coffee shop on battery). It's macOS only for now, but ping me if you are willing to test the Windows or Linux version. I've been…
