What it does
VaultSync syncs your Obsidian vaults to iPhone and iPad using Syncthing. Your notes stay on your own devices, with optional push wakeups for faster server-to-iPhone updates.
Self-hosted Obsidian vault sync for iOS — powered by Syncthing. - psimaker/vaultsync
Self-hosted Obsidian vault sync for iPhone and iPad. Your notes sync peer-to-peer over Syncthing, straight into Obsidian's iOS sandbox — no note cloud, no account, no tracking. VoiceOver and Dynamic Type throughout. Localized in English, German, Spanish, and Simplified Chinese. Independent project — not affiliated with Obsidian or Syncthing. Syncthing runs on a machine you keep on; VaultSync joins as a peer and syncs into Obsidian. After a server change, the optional sidecar + Cloud Relay can request an iOS background wake-up; iOS decides whether and when VaultSync runs. Without it, VaultSync syncs server changes when you open the app. With it, Cloud Relay can request a background wake-up…from github.com

macOS Reminder Sync for Obsidian Tasks2024 · turquoisehexagon.co.uk · ▲155Greetings, 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…

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.

Cc-md – Zero-cost Obsidian sync across iPhone, Mac, and GitHubFeb 2026 · github.com · ▲8Here'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…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
