https://github.com/acheong08/obsidian-sync Hello HN, I'm a recent high school graduate and can't afford $8 per month for the official sync service, so I tried my hand at replicating the server. It's still missing a few features, such as file recovery and history, but the basic sync is working. To the creators of Obsidian.md: I'm probably violating the TOS, and I'm sorry. I'll take down the repository if asked. It's not ready for production and is highly inefficient; Not competition, so I hope you'll be lenient.

A few months ago I noticed that I was quickly approaching my 10GB sync limit for my daily driver vault. I considered deprecating some of the heavier files and images, but I was worried how it would affect the integrity of my vault. Instead, I took the opportunity to think to myself -- what would the perfect vault look like? I began to write down some of the key philosophies and strategies I use in my driver vault which led to indispensable plugins, which led to more indispensable philosophies and on and on it went. I've chronicled these results into a fully working vault template that…

Hey HN! Today we're launching Agent Vault - an open source HTTP credential proxy and vault for AI agents. Repo is at https://github.com/Infisical/agent-vault, and there's an in-depth description at https://infisical.com/blog/agent-vault-the-open-source-crede.... We built Agent Vault in response to a question that been plaguing the industry: How do we give agents secure access to services without them reading any secrets? Most teams building agents have run into this exact problem: They build an agent or agentic system and come to realize at some point…

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…

Obsidian plugin that connects to CLI agents you already have installed. No built-in LLM integration, no API keys to configure in the plugin. It spawns your tool as a child process, pipes vault context into each prompt, and streams responses into a chat panel. Supports Claude Code, Opencode, and any custom binary via a generic adapter. Adding a new agent is a single file. Free, proudly Open Source (MIT licensed). Would love feedback on this for anyone that that tries it out.

Here's something I realized: the most AI-native knowledge base isn't a SaaS product with an API. It's a folder of markdown files on your disk. Obsidian stores everything as plain .md files. That means Claude Code (or any AI tool) can grep, read, write, and traverse your entire knowledge base with zero setup. No API keys. No OAuth. No middleware. Just local file I/O. The only missing piece was sync. I wanted my vault on iPhone (iCloud), on Mac (local), and on GitHub (backup + version history) — without paying $4/mo for Obsidian Sync. cc-md is ~400 lines of bash. iCloud handles Apple…
