Offline-first app development services with SQLite and CRDTs
Offline-first app development services keep apps fast and usable without a connection. Omeiro puts SQLite in the browser with WASM, syncs it to your database using PowerSync or ElectricSQL and resolves edits with CRDT merging.
Users work against local data, and changes sync as soon as they reconnect.
Offline-first app development: choosing what lives on the device
Offline-first app development begins by deciding which data must be available without a connection. A sales rep may need customers and orders; a warehouse worker, stock lists and tasks. Storing everything locally wastes space and complicates security. Bring your data model and the roles who use the app. Basic keeps up to 5 tables in an in-browser SQLite database, which suits a single-user tool.
Sync rules are the harder half. When two devices change the same record offline, the system must merge them predictably, and CRDT-based resolution does this without losing either edit. Premium adds partial sync so each user receives only their slice of the data. Good offline-first app development makes screens respond instantly, keeps people working through poor signal and sends changes to Postgres when the connection returns.
Who needs local-first software
- Field teams working with unreliable signal.
- Productivity apps that must feel instant on every tap.
- Teams exploring local-first software development for a new product.
- Developers needing crdt sync development or a sqlite sync development company.

How long does local-first software development take?
Delivery depends on the package: Basic 10-day delivery; Standard 21-day delivery; Premium 35-day delivery.
What is included in the Basic Package?
The Basic Package includes: In-browser SQLite (WASM) local store for 1 app, 5 tables. Higher packages add more scope, revisions and support.
Can I get a custom crdt sync development package?
Yes. If none of the packages fits, use the custom package form on this page to describe what you need, and our team sends you a fixed price.
Is data safe on the device?
Local data needs the same care as any stored data, and we discuss what should be cached when scoping.
What is partial sync?
It syncs only the rows a user needs, which keeps devices light. Premium includes it.
Which backend database is used?
The sync described here targets Postgres.
Does it work on mobile?
Premium covers web and mobile.
What is the difference between offline-first and local-first software?
Offline-first treats the network as optional but the server still owns the data. Local-first goes further, making the device copy the main working copy with sync as a background service.
How are conflicts resolved when two people edit offline?
CRDT data types merge changes mathematically so both edits are kept where they do not clash. For fields that do, a rule such as latest change wins is chosen with you in advance.
