Painless Database Synchronization
Synchronize SQLite and MS SQL databases between mobile devices and your server — fast, reliable, and with zero custom sync code.
Complete database synchronization — without writing a line of sync code
SyncStudio is HandApps' proprietary database synchronization tool that enables offline-first mobile, desktop, and web applications. It allows developers to implement a full database synchronization solution in minutes rather than weeks or months.
Using the SyncStudio API, developers embed full support for synchronization and replication into their offline apps. SyncStudio supports SQLite or MS SQL (including LocalDB and Express) at the client and Microsoft SQL Server on the server.
Built on the Microsoft Sync Framework with proprietary extensions, SyncStudio completely eliminates the need for custom synchronization code — handling configuration, provisioning, code generation, deployment, and management automatically.
- Syncs SQLite and MS SQL with Microsoft SQL Server
- Supports Android, iOS, MAUI, Xamarin, Basic4Android, and Windows Forms
- Zero custom synchronization code required
- Built on Microsoft Sync Framework with proprietary extensions
- Automatic code generation, provisioning, and deployment
- Runs on your own infrastructure — no cloud charges
- Transactional integrity with full commit/rollback support
The engine behind Kaela's offline-first architecture
SyncStudio is the technology that makes Kaela offline-first. When field reps, drivers, and B2B buyers use Kaela in the field — in warehouses, trucks, rural delivery routes, restaurant kitchens, or store basements — they're working with a local SQLite database synchronized by SyncStudio.
ERP data flows from Microsoft SQL Server via the HandApps platform and SyncStudio's sync engine, down to the mobile devices. When connectivity is available, users sync their changes back — with full transactional integrity. What data goes to which user is easily defined using our robust filtering functionality.
This is why Kaela works reliably everywhere your teams work — not just where there's WiFi.

Everything you need for database synchronization
SyncStudio handles the entire sync lifecycle — from configuration to deployment to ongoing schema changes.
SyncStudio SMC
A visual management console where you define your sync project. Connect to your database, choose tables, fields, filters, and sync rules — then deploy with one click.
Auto Code Generation
SyncStudio automatically generates and compiles your custom sync web service. Your synchronization coding effort is exactly zero.
Auto DB Provisioning
Prepares databases for synchronization automatically — triggers, stored procedures, and tracking tables are created and configured for you.
Data Filtering
Control which records sync to each client on a table-by-table basis. Define filtering codes by user, region, role, or any custom criteria.
Schema Synchronization
Database structure changes propagate automatically to all clients on next sync. Modify your server schema and every device updates itself.
Automated IIS Deployment
Deploy your sync service directly to IIS from within SyncStudio. No manual server configuration or deployment scripting required.
Reliable, scalable, and production-ready
Transactional Integrity
Each sync session is one SQL transaction. All changes commit or all roll back. No partial syncs.
Built-in Batching
Large data sets handled automatically across multiple transmission batches for reliable sync over any connection.
Auto Client DB Creation
Deploy client-side databases to thousands of devices without manual provisioning or device-by-device setup.
Minimal Client Config
Simple API integration means developers focus on their app, not sync plumbing.
No Cloud Charges
Runs on your own infrastructure. No per-sync fees, no metered cloud costs, no surprises.
Custom Schema Config
Full control over which tables, fields, and indexes are synchronized in every sync project.
Bi-directional Sync
Data flows both ways — server to device and device to server — with automatic conflict resolution.
100% USA-Based Support
Designed, developed, and supported by the HandApps team in the USA.
