Web Application Developers

You're building the future of work. Why do your apps still break when the internet hiccups?

You're here to build the productivity tools, collaboration platforms, and digital experiences that power how people work and create. But you're still stuck with a client-server model from the dial-up era. Your "cloud-native" apps become useless the moment WiFi cuts out. Your real-time collaboration turns into a frustrating mess of version conflicts and lost edits.

Web apps should work like the best desktop software — always responsive, always available.

Source gives you a complete database that runs directly in the browser — turning every web app into a local-first powerhouse that happens to sync, not a server-dependent app that sometimes works offline. With DefraDB, your users get the reliability they expect with the collaboration features they demand, regardless of network conditions.

The Architecture That's Holding Everything Back

You came here to build transformative user experiences, not to babysit client-server complexity:

Get Started

The entire web stack assumes constant connectivity — but your users live in a world of coffee shop WiFi and subway tunnels

"Real-time collaboration" is a joke when it means users staring at loading spinners during network blips

You're building two separate apps — one for online mode and another for offline, and they never quite work the same way

Privacy compliance is a nightmare — GDPR, data residency laws, and field-level access controls require custom governance layers that slow development to a crawl

Every feature requires server roundtrips that add latency, cost money, and create failure points

Global deployment means infrastructure gymnastics to handle data sovereignty across jurisdictions without violating regulations

Scaling means expensive server infrastructure to handle queries that could run perfectly fine in the browser

The client-server model worked when computers were dumb terminals and privacy laws didn't exist. Your users deserve better.

Build web apps that work like the future, not the past

DefraDB runs entirely in the browser via WebAssembly.

No more online/offline mode complexity. No more server dependencies for basic functionality. No more accepting that web apps have to be inferior to native apps.

What becomes possible when you break free from client-server limitations:

Get Started

Instant everything

All queries run locally — every interaction is immediate, no matter what the network is doing

Bulletproof collaboration

CRDTs handle concurrent edits automatically, making real-time collaboration actually reliable

Zero-downtime resilience

Your app works perfectly whether users have gigabit fiber or airplane mode

Global deployment without the headaches

Meet data sovereignty requirements without building separate infrastructure

Built-in compliance

Field-level access controls and privacy protections are part of the database, not custom code you maintain

True user ownership

Data lives on users' devices first, syncs when convenient, not when required

What You Actually Get

Weeks of infrastructure complexity eliminated

Read the Docs

Stop building separate online/offline codepaths that never quite sync up

Eliminate expensive server infrastructure for queries that should run locally

Deploy globally without jurisdiction-specific compliance infrastructure

Handle real-time collaboration without custom operational transform implementations

Build once, run everywhere — browser, mobile, desktop with the same database

Architecture that matches user expectations

Get Started

WebAssembly-native

Full database power running directly in the browser

Conflict-free by design

Automatic merge resolution that actually works for collaborative editing

Instant responsiveness

Zero server roundtrips for queries means zero waiting

Compliance without complexity

GDPR, data residency, field-level permissions built into the database

Schema evolution

update your data model without breaking active user sessions
