A big tech dev experience for an open source CMS
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…

In plain words
Content Foundry is an open-source CMS platform designed to help creators manage the full content production pipeline. The team has released an initial tool that generates identity cards from Twitter usernames using a Constitutional AI approach, emphasizing repeatability and testability. The system is intended to support both model finetuning and inference-time insights for language models. The project prioritizes developer experience and community contribution, aiming to provide a more accessible alternative to existing content management systems.

Turn any website into a knowledge base for LLMs2024 · embedding.io · ▲305I built this tool because I wanted a way to just take a bunch of URLs or domains, and query their content in RAG applications. It takes away the pain of crawling, extracting content, chunking, vectorizing, and updating periodically. I'm curious to see if it can be useful to others. I meant to launch this six months ago but life got in the way...
XBeast2024 · xbeast.io · ▲228A few weeks ago I realized i was spending way too much time trying to write quality posts for Twitter. So I decided to look into scheduling tools which could help me automate my writing. I tried a few, but none of them satisfied me. Either the interface was way too complicated or the features i wanted were just not there. Finally, after some time I gave up… and instead I decided to just do it! I hacked up a quick prototype in a weekend. Tried it out - it worked!! Mostly.. I fixed some bugs, made a nice UI, and now (3 weeks later) I think I built one of the nicest scheduling tools out there.
I’m building open-source headless CMS for technical content2023 · vrite.io · ▲89In 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…
OpenCopilot – Build and embed open-source AI copilots into your product2023 · github.com · ▲109Hey HN OpenCopilot is an OSS framework which helps devs to build open-source AI Copilots that actually work and embed into their product with ease. Why another LLM framework? Twitter is full of impressive LLM applications but once you peel off the curtains it’s clear that they are just demos. The reason being because building an AI Copilot that goes beyond a Twitter demo can be complex, time-consuming and unreliable. Our team has been in the AI space since 2018 and built numerous LLM apps & copilots. While doing that, we got approached by many startups saying they’d also like to build a…

MirrApr 2026 · mirra.my · ▲42Hi HN! I'm Tae, a solo developer from Seoul. I've been building Mirra for the past year. The problem: creating consistent social media content is a massive time sink for small businesses and creators. Writing posts, designing carousels, editing videos – it takes hours every week. Mirra lets you go from a raw idea to ready-to-publish content in minutes: - Type an idea or paste a URL → AI generates carousel slides, short-form video scripts, and captions - Supports Threads, Instagram, LinkedIn, YouTube Shorts, TikTok - Built-in scheduler to publish directly The core insight was that most…
