24 alternatives to Foundry: a Markdown-first CMS written in Go

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:…

Foundry is a markdown-based CMS written in Go that combines the simplicity of static site generators with more advanced features. It supports themes, archetypes, preview workflows, and a hook-based plugin system while… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

An open-source, collaborative, WYSIWYG Markdown editor▲460
Inspired by the design and UI/UX of apps like Notion, and utility of open-source apps like StackEdit, I decided to create a minimalistic, local-only WYSIWYG Markdown editor. Some features worth highlighting: - Monaco editor and Prettier integration for code snippets - Tables (apparently the holy grail of WYSIWYG editing) - Embeds (for CodePen, CodeSandbox and YouTube, most useful for HTML or JSON exports) - Accepts Markdown paste-in, and "exports"/generates HTML, Markdown and JSON outputs - Collaboration (with real-time awareness and initial commenting system, available only when…

Flowershow▲174
I'm Rufus, one of the founders of Flowershow. We love markdown and use it everywhere from making websites, to docs, to knowledgebases. Plus AI splits it everywhere now. Got tired of the framework/config/deploy overhead every time we wanted to share a file or put a site online. So we built the thing we wanted. Files in. Website out. "Vercel for Content" is our aspiration - make deploying (markdown) content as fast, seamless and easy as Vercel did for JS. Command line plus you can connect to github repos, use Obsidian via plugin, or drag and drop files. npm i -g…

Forge – Guardrails take an 8B model from 53% to 99% on agentic tasks▲687
Hi HN, I'm Antoine Zambelli, AI Director at Texas Instruments. I built Forge, an open-source reliability layer for self-hosted LLM tool-calling. What it does: - Adds domain-and-tool-agnostic guardrails (retry nudges, step enforcement, error recovery, VRAM-aware context management) to local models running on consumer hardware - Takes an 8B model from ~53% to ~99% on multi-step agentic workflows without changing the model - just the system around it - Ships with an eval harness and interactive dashboard so you can reproduce every number I wanted to run a handful of always-on agentic systems…

next-forge by Vercel▲326
Hey folks, I'm building a free and open-source monorepo template for "production-grade Next.js apps". Basically everything you need to go from "new idea" to "Series A level product" very quickly. It's almost at 500 stars on GitHub so I thought I might share it here. It comes pre-configured with analytics, auth, a blog, dark mode, transactional email, feature flags, monitoring, ORM + database, payments and heaps more. It's quite opinionated but very fast and very neat. I hope it helps you make something awesome.

htmgo - build simple and scalable systems with golang + htmx▲166
Hey all, I just wanted to share a project I've been working on for the past month. After years of heavy frameworks, I really like the idea of using htmx, but it’s a little too low level for me and needs a thin layer above it to facilitate things like components, better syntax with complex JS inside of an attribute, etc To try and solve this problem with a very minimal stack (golang + htmx) that I've been really enjoying, I'm building this project to cater to my needs and was thinking it would be useful for other developers.

A big tech dev experience for an open source CMS▲58
Hey HN! We're building an open-source CMS designed to help creators with every part of the content production pipeline. We're showing our tiny first step: A tool designed to take in a Twitter username and produce an "identity card" based on it. We expect to use an approach similar to [Constitutional AI] with an explicit focus on repeatability, testability, and verification of an "identity card." We think this approach could be used to create finetuning examples for training changes, or serve as inference time insight for LLMs, or most likely a combination of the two. The tooling we're…

HTML-to-Markdown – convert entire websites to Markdown with Golang/CLI▲360
Hey HN! I originally built “html-to-markdown” back in 2018 (while still in high school) to handle complex HTML conversions where other libraries struggled. Now, I’ve released v2 — a complete rewrite designed to handle even more edge cases. It supports entire websites with a high accuracy. Example use: I’ve used it in my RSS reader to strip HTML down to clean Markdown, similar to the "Reader Mode" in your Browser. It can be used as a Golang package or as an CLI. Give it a try & tell me what edge cases you encounter!

display.dev▲183
Last week's post from Thariq "The Unreasonable Effectiveness of HTML" went viral in X. He made a good point about HTML being the more expressive and human friendly alternative to markdown files. I completely buy in where he's coming from, I've been asking Claude Code to create me HTML files to better understand what we're planning and building together. What Thariq didn't address was the part of sharing and collaborating on these HTML artifacts (he proposed uploading to S3). While I've been heavy user of HTML artifacts to share quarterly plans, implementation specs, technical guides and…

Mdx – Execute your Markdown code blocks, now in Go▲127
Hey HN! I recently came across makedown here on HN and loved the concept. Wanting to learn Go, I thought this could be a great starter project - so I started working on my own Go implementation, which I’m calling mdx (https://github.com/dim0x69/mdx). Key Features: - Define dependencies between commands - Supports shebangs - Ability to pass arguments to code blocks Would love feedback and thoughts! Ref. makedown: https://github.com/tzador/makedown. Thanks for the idea! :)

Writemark, a dependency free web component for inline Markdown editing▲53
I like writing Markdown, but do not like writing it inside a plain textarea. I wanted something I could use anywhere by dropping in a single web component: ``` ``` That became Writemark. It renders Markdown while you write, but Markdown remains the value you read, store, and submit. It also has source, split, and preview modes, along with slash commands, tables, task lists, code blocks, native form support, and an API for adding your own controls. There are no runtime dependencies and no required framework or built in toolbar. It is fully vibecoded. The process was very iterative. I knocked…

Use Go's HTML/template to write React-like code▲106
Hi all, I'm currently working on my hobby project, and one of the fun constraints I put in was to build using as less dependencies as possible. I chose Go as it has a really good standard library, and all went well for building backend. But for frontend, I was wondering whether I should break the constraint and go for React. I tried options like Web Components, but I really didn't like the ergonomics and I didn't want to use jQuery either. Out of curiosity, I was exploring Go's html/template package to see if I can write UIs in a React-like manner. I found most of the online docs using…

Makedown – A Markdown powered Makefile alternative▲142
`makedown` allows you to organise your shell scripts in one or several markdown files, by mix and matching different scripting languages for various commands and needs. zsh/bash/sh, python, javascript or anything else available on your system. Handy for replacing one-line-based package.json scripts or shell-based Makefiles. One can also write documentation and explanations to various commands in the same `.md` file. Most editors highlight correctly most languages in the markdown code blocks, even when you use several scripting languages. Here is a demo .md file…

I wanted to be able to write posts on my phone, and it's not easy to do that with Markdown.

Use your familiar Markdown editor to create and publish web pages▲62
I'm excited to introduce my own developed Markdown editor to everyone. It's built on the Monaco editor and designed specifically for developers. This editor integrates various features such as document management, resource management, and MDX extensions. You can embed images, audio, video, and even use plugins like drawing tools, calendars, and cards to showcase your creativity. What's even more thrilling is that it allows users to customize PostgreSQL table structures, insert and display data in Markdown documents, and even collect form submissions. My original intention in design was to…

I’m building open-source headless CMS for technical content▲89
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…
