Hubble: bholmesdev Ships an Open-Source Markdown Notepad Designed to Be Written To by Agents, Not Just Humans
Hubble (hubble.md) hit 126 points and 57 comments as an open-source, free notetaking app built on Markdown and HTML and pitched as 'the best notepad for you and your agents.' It organizes around three claims — feels familiar, agent ready, build any view — positioning the note store as a shared workspace an agent can read and write rather than a human-only sink. It was built by Ben Holmes (@bholmesdev) and the GitHub repo showed 61 stars at time of the HN post, so this is very early. The specific agent integration protocol is not stated on the landing page, which is the main open question for anyone evaluating it against an MCP-native notes setup.
