Description
Hi HN! I've been building a CMS called Foundry, brought together from multiple smaller private projects as well as greenfield code.The short version is: it's a CMS written in Go with a focus on markdown content, a simple hook-based plugin model, themes, archetypes, preview flows, and a clean authoring/developer experience.I started working on it because I wanted something that was more powerful than Hugo for a few of my websites, without having to resort to dangling onto a database.What seems different about it, at least to me, is that I'm trying to keep the system small in concept: local content, explicit behavior, compile-time plugin registration, and an admin/editor layer that is meant to stay close to how the content actually lives on disk. The goal is not to make "yet another website builder", but to make a CMS that is easy to use and quick to onramp onto, but has powerful advanced features and extensibility.Still early, but usable enough that I wanted to put it in front of people here and get feedback. Please don't castigate me on the UI look - I'm not a designer, and the themes are basically clones of each other.Happy to answer technical questions, architecture questions, or hear where this seems useful versus where it does not.

Discussion
8 comments analyzed.
Competitors mentioned: Voiden (markdown-first alternative), WordPress (CMS architecture reference), Palantir Foundry (potential name conflict)
Concerns raised: Legal trademark issues with Palantir over 'Foundry' name at scale, Website and UI design appear AI-generated and unprofessional, Difficulty maintaining 'small core' philosophy while handling useful feature requests, Community adoption and scaling uncertainties

Same idea, different domain
Nobody's really built a vertical saas tool for Insurance yet.
