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

    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…

    Open-source obsidian.md sync server2023 · ▲416

    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 · ▲8

    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…

    Bi-directional sync between Postgres and SQLite2023 · powersync.com · ▲356

    Hi HN, Today we’re launching PowerSync, a Postgres<>SQLite bi-directional sync engine that enables an offline-first app architecture. It currently supports Flutter, React Native and web (JavaScript) using Wasm SQLite in the browser, with more client SDKs on the way. Conrad and I (Ralf) have been working on our sync engine since 2009, originally as part of a full-stack app platform. That version of the system is still used in production worldwide and we’ve learnt a lot from its use cases and scaling. About a year ago we started on spinning off PowerSync as a standalone product that is…

    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:&#x2F;&#x2F;text.blogosphere.app&#x2F; Non-minimal: https:&#x2F;&#x2F;blogosphere.app&#x2F; If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
