Cc-md – Zero-cost Obsidian sync across iPhone, Mac, and GitHub
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…

What it does
Obsidian 零成本同步：iPhone ↔ Mac，GitHub 自动备份。本地优先 + 长期积累。｜Local First. Zero-cost Obsidian sync across iPhone, Mac & GitHub. Let knowledge grow over time. - yuukiLike/zeromd
Local-first Obsidian multi-device sync. Zero cost. Zero signup. Zero maintenance. The most AI-native knowledge base isn't a SaaS product with an API. It's a folder of markdown files on your disk. And .md isn't done evolving — Mermaid already turned plain text into live diagrams. Interactivity might be its next chapter. Obsidian stores everything as plain .md files. AI tools like Claude Code can read and write your knowledge base directly : # Claude Code works with your vault natively Grep " system design " ~ /vault/ # search all notes Read ~ /vault/some-note.md # read content Edit ~ /vault/some-note.md # modify content Glob " **/*.md " ~ /vault/ # traverse entire knowledge base Compare with…from github.com

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 highly opinionated, fully functional Obsidian vault2022 · github.com · ▲258A 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…
- YAYAOS – A 1-click deploy, real-time sync engine for ObsidianMar 2026 · ▲5
Hey HN, I'm a heavy Obsidian user. I recently got tired of the two usual sync tradeoffs: 1. File-based sync (iCloud/Dropbox/Syncthing) that leaves you waiting for changes to propagate, or hands you a "conflicted copy." 2. Self-hosted setups (like CouchDB) that need touching VMs and dockerized databases to sync markdown. So I built YAOS: a local-first, real-time sync engine for Obsidian. Self-hosting OSS should have better UX. You can deploy the backend to your own Cloudflare account in one click. It fits comfortably in Cloudflare's free tier (costing $0/month for normal…

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
