1
🔍 Discover the sync tool

You find a helpful tool that lets your mobile app save data even without internet and sync it later.

2
📱 Add it to your app

You simply include the tool in your app project so it's ready to use.

3
đź”— Connect your storages

You link your app's local notebook for saving data and your online service for sharing it.

4
đź“‹ Choose what to sync

You pick the types of information, like workout logs or notes, that should stay in sync across devices.

5
✍️ Save and change data

Whenever you add, update, or delete something in the app, it saves instantly locally and prepares to update online too.

6
🔄 Sync everything smoothly

On app start or when online, it smartly matches up only the changes, fixing any mix-ups automatically.

What is dynos-sync?

dynos-sync is a production-hardened sync engine built for Dart and Flutter apps needing offline-first reliability. It handles writes locally first, queues them for the remote backend like Supabase, and performs delta-pulls to fetch only changes since last sync—targeting 50k+ writes/sec with zero-jank performance via background isolates. Developers get atomic local writes, automatic conflict resolution, and events for UI feedback, plugging into Drift for local storage.

Why is it gaining traction?

It stands out with high-performance features like batch pushes, exponential backoff retries, PII redaction, and row-level security checks, all passing a 140-test security audit for HIPAA/GDPR compliance. Delta-pulls skip unchanged tables using remote timestamps, minimizing data transfer, while runtime table registration and logout wipes ensure flexibility without custom boilerplate. The bundled Drift and Supabase adapters make setup dead simple for common stacks.

Who should use this?

Flutter devs building mobile apps with offline data needs, like fitness trackers syncing workouts or task managers handling spotty connections. Ideal for teams using Drift SQLite locally and Supabase remotely, especially those dealing with user-owned data requiring RLS and conflict strategies beyond last-write-wins.

Verdict

With 12 stars and 1.0% credibility score, this v0.1.5 package is early-stage but packs solid docs, benchmarks, and a security audit—worth prototyping if your Dart/Flutter app matches the Drift/Supabase stack. Skip for production without more real-world usage.
