What makes a good AI application?

Let's learn from the top 3 projects of the PowerSync AI Hackathon

PowerSync Changelog: March 2026 Over the last few weeks we had a lot of fun running our first hackathon. We had several very solid submissions and many of you came up with great use cases for sync-powered AI. It's also been another big month of shipping things.

Full Changelog www.powersync.com/blog/powers...

March was a big month for PowerSync.

We shipped:
🗄️ SQL Server support beta
🟣 .NET SDK beta
📉 Query-driven sync for TanStack DB
🦀 Native Tauri SDK
💚 First-class Nuxt support

Plus, our AI hackathon gave us a lot of useful signal from builders working on sync-powered AI apps.

Introducing the PowerSync Tauri SDK (Alpha) We've released a native Tauri SDK into alpha. Tauri is a popular Electron alternative that uses web technologies for the UI and Rust for the backend, making...

Release notes releases.powersync.com/announcemen...

This alpha release replaces broken WebView storage with native Rust + filesystem SQLite.
It's early, it's alpha, and it needs your testing.

→ Watched queries and table updates coordinated centrally

If you've tried using the Web SDK in Tauri and hit the IndexedDB wall—where your database resets on every build, losing unsynced writes—you know why this matters.

🚀 @TauriApps developers, we fixed the storage problem.
Introducing the PowerSync Tauri SDK (alpha):

→ Filesystem-based SQLite (data persists across app updates)
→ Native performance without WASM overhead
→ Automatic sharing of sync state across all windows

SQL Server Backend Database Support: Beta Release SQL Server backend database support in PowerSync has reached beta , meaning it's production-ready for tested deployments. We're also releasing the PowerSync...

→ Cloud and hybrid deployment scenarios

Along with the beta PowerSync .NET SDK, teams building on the Microsoft stack now have production-ready PowerSync support.

🌐 PowerSync backend support for SQL Server is now beta and production-ready for tested deployments.

→ CDC-based replication from existing SQL Server databases
→ Automatic schema change detection and handling
→ Support for Standard, Enterprise, Developer editions

PowerSync .NET SDK: Beta Release The PowerSync .NET SDK has reached beta . You can now build and ship production-ready desktop and MAUI apps with the full PowerSync feature set....

Release notes releases.powersync.com/announcemen...

We rewrote the query layer with Dapper, swapped in our Rust sync engine, and optimized every piece for the .NET runtime. The result is an SDK that feels right at home in your .NET projects.

✓ Live queries that stream updates via IAsyncEnumerable
✓ Connection pooling and thread-pool execution for performance
✓ Full MAUI and desktop support

💻 .NET developers, your sync SDK has arrived.

The PowerSync .NET SDK is now beta with everything you need for offline-first applications:

✓ Stable APIs (breaking changes will be communicated clearly)
✓ Sync Streams for flexible sync strategies

Huge thanks to everyone who participated in the PowerSync AI Hackathon — we were blown away by the submissions

Query-Driven Sync for the PowerSync TanStack DB Collection The @tanstack/powersync-db-collection package now supports TanStack DB's query-driven sync — on-demand sync mode where the collection only loads the rows...

Release notes: releases.powersync.com/announcemen...

🚀 Big update for @tanstack.com DB users!

powersync-db-collection now supports Query-Driven Sync.

No need to load 50,000 rows into memory when you only need to show 20. On-demand mode compiles your live TanStack DB queries into SQL for efficient data loading.

That’s a wrap on submissions for the PowerSync AI Hackathon.

54 projects are now in the hands of our judges. Thanks to every team and solo builder who joined, built fast, and pushed creative ideas forward. Winners soon.

How easy is it to go from a simple specification of a feature to a fully working implementation with AI?

Turns out, pretty easy once you got PowerSync!

PowerSync AI Hackathon builders, what are you working on?

Would be great to see what people are shipping this weekend.

Local-First Software: Taking Back Control of Our Data | a mini-doc YouTube video by CultRepo

"How much of this can be local" should be the default question every dev asks. Most have gotten too comfortable with defaulting to remote hosting even the tiniest services. Glad to see a growing pushback for local-first.

A nice mini-doc from @cultrepo.bsky.social
