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…

Hi, I made a bridge (https://github.com/fzyzcjy/flutter_rust_bridge v2.0.0) between Flutter and Rust, which auto translates syntaxes like arbitrary types, &mut, async, traits, results, closure (callback), lifetimes, etc. The goal is to make a bridge between the two, seamlessly as if working in one single language. Then, as an example, I showed how to write Rust applications with GUI by utilizing Flutter. That is discussed in the link in details. To play with it, please visit the GitHub repo, or refer to the end of the article for detailed folders and commands. When I…

Hi HN, We have been building SyncLite, an open-source platform to simplify offline-first application development. If your application uses SQLite or DuckDB, SyncLite lets it continue using the local database as usual while synchronization happens in the background. For SQL-based applications, SyncLite records transactions into transactionally consistent .sqlog files using SQLite as an open replication format. A background consolidator replays those transactions, derives row-level CDC and schema changes, and applies them transactionally to destination databases like PostgreSQL. The same…

Hi HN, I've been waiting to post what I've been working on for a few weeks now:) Today we're launching LayerVault, which is a version control system made for designers. The URL is http://www.layervault.com LayerVault keeps track of what you're working on without adding extra steps to your process. The app runs in your toolbar and tracks changes you make to your files. Basically — each time you create or modify a file you’re working on, LayerVault saves a copy. You can then login, flip through its versions, and download a version from a few weeks ago. It's pretty neat — and we’ve built some…

OVault is a super simple iOS and macOS app that lets you store and view your OTP codes for two factor authentication. I found that my personal favourite OTP app Authy seemed to be getting worse with each iOS release. Its usability has never been great, and iOS 18 meant that it lost its Home Screen Widget that let me view my OTP codes without opening the app. I decided to switch to another app, then became frustrated that I couldn't easily export my secrets from Authy. Of course I'm sure there are good security related reasons for this, but I didn't want to migrate all my OTPs just to end up…

Sync-in▲79Hi HN, I’m happy to announce the public launch of Sync-in (https://sync-in.com) — a secure, open-source platform to store, sync, organize, and collaborate on files, without compromising privacy. Sync-in wasn’t born from a business plan, but from a personal need: being able to access my files remotely, share them easily with family or colleagues, and protect my data — through a clean, responsive, and user-friendly interface. Over the past 10 years, it has evolved and matured to support individual, team, and organizational workflows. You can host your own workspace to organize,…
