24 alternatives to 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…

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…

Hi HN, Nick here. We’re launching OpenKnowledge (https://openknowledge.ai/), a “what you see is what you get” markdown editor that has direct integrations with Claude, Codex, and other agents. Available as MacOS app or Web UI+CLI. Fully free/local and OSS. We built this because we wanted a Notion-like experience for writing and sharing markdown files across our team. Obsidian is the best alternative we tried, but found it doesn’t have a true WYSWIG UI and it didn’t integrate well with Claude/Codex outside of community plugins. So we built OpenKnowledge. It takes…

Greetings, I started using Obsidian and the brilliant Obsidian Tasks plugin to manage Tasks in my notes however it didn't quite work for me as I would lose track of Tasks when away from my laptop, and there are no reminders for Tasks so it's not easy to stay on top of things. I wrote my first macOS App to solve the problem; Reminder Sync for Obsidian. It periodically scans your Obsidian Vault for Tasks and creates Reminders for them in Reminders.app! Once your Tasks are created as Reminders they are synced through iCloud so they are also visible on iOS; this solves the main problem I had…

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…

Hey HN! I built Retain as the evolution of claude-reflect (github.com/BayramAnnakov/claude-reflect). The original problem: I use Claude Code/Codex daily for coding, plus claude.ai and ChatGPT occasionally. Every conversation contains decisions, corrections, and patterns I forget existed weeks later. I kept re-explaining the same preferences. claude-reflect was a CLI tool that extracted learnings from Claude Code sessions. Retain takes this further with a native macOS app that: - Aggregates conversations from Claude Code, claude.ai, ChatGPT, and Codex CLI - Instant full-text…

Hi HN, I'm Adriano, one of the makers of Vaultrice. I'm excited (and a little nervous!) to share what we've been building. For years, we found ourselves in a frustrating loop: whenever we needed a simple real-time feature—like a "who's online" list, a collaborative app, or just sharing state between a marketing site and our main app — we'd end up spending days setting up the same stack or discarded to do it. Setting it up, it always involved wiring together a database, a WebSocket server, an API, and managing the connection state. It felt like massive overkill for what we were trying to…

Hi HN, I built this simple command-line tool to solve a specific pain point in Obsidian plugin development. As a new plugin developer, I didn't like the idea of manually copying files from my development directory to the Obsidian vault every time I made changes. Obsidian Plugin Sync automates this process with a single command. It: - Detects plugin ID from manifest.json - Optionally builds your plugin before syncing - Copies the necessary files to your Obsidian vault - Provides a watch mode for continuous syncing during development The tool has zero dependencies beyond Python for basic…

Hi HN. I tested literally dozens of note-taking apps over the years — free, paid, everything. They all sucked except UpNote. Great UX, clean, fast, just works. But your data lives in Google Firebase. Dealbreaker. So I tried Obsidian. Local files, markdown, own your data — great philosophy. But the app itself? Even with everything disabled, as a plain markdown editor it was painful. I actually stopped taking notes entirely. So I built what I wanted: inspired by UpNote's clean design but taken further; less clutter, more polished, with Obsidian's local-first ideology. Your notes are standard…

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.
