Flux handles state sync, offline resilience, and Client Side caching in one engine so your backend only hears from your app when something actually needs to change.
Across 10,000 daily active users. Architecture, not estimate.
Every tab. Every refresh. Every session.
You are paying for compute the browser could have handled efficiently. Your users are left waiting for data layers they already downloaded completely moments ago.
There is a better architecture. The browser stores it. The browser syncs it. The browser resolves it locally. Your server only moves when something actually changes.
Once your application loads the initial data envelope, Flux pre-populates your local stores directly from disk before components even mount. Enjoy zero layout shifts and zero spinners on any return visit.
Our cross-tab bootstrap leader election forces a single tab to orchestrate the outbound network request while every other parallel tab hydrates synchronously from disk. Ten tabs open; your server logs one hit.
When a disconnected browser returns online, the leader tab passes cryptographic sync anchors to the adapter. Your server streams only the delta changes missed during the gap instead of hitting a heavy, full database re-bootstrap.
Edits performed offline flow through a resilient 3-layer fallback pipeline. Your data is guaranteed safe against unexpected tab closures, mobile browser crashes, and aggressive OS sleep cycles.
If a record changes concurrently on the server while a user modifies it offline, a precise two-pass handshake traps the collision before touching your ledger. Resolve conflicts cleanly on your own terms.
Enforce ironclad data boundaries on shared public machines. Private data channels, cache nodes, and queued mutations are rigidly scoped per authenticated identity and explicitly scrubbed out the moment a user logs out.
Flux orchestrates the complex web primitives entirely behind the scenes: the background Service Worker layer, namespaced local cache lifecycles, and predictive asset warming. When a page mounts, data chunks are fetched as part of a single bootstrap request to prevent request stacking.
The step remaining on your side is completely static: provide a standard manifest.json containing your application identity blueprints and application icons.
Your infrastructure bills, relational database connection limits, and serverless edge function invocations fall instantly.
This mitigation scales directly because Flux captures redundant reads locally, intercepting duplicate runtime cycles before traffic ever knocks on your gateway.
Based on immediate local data hydration and leader tab synchronization rules.
Every registered store reads its IndexedDB envelope in parallel before any component mounts — a 2000ms hard timeout guarantees the app never blocks on cache.
'user'-scoped stores resolve to keys namespaced per tenant in IndexedDB, structurally separate from global data — cleared on logout, self-healed on next boot.
One leader tab fires one network request per scope. Follower tabs hydrate from disk instead of duplicating the fetch.
Reconnects stream only what changed while offline, using per-channel sync anchors — never a full re-fetch of the dataset.

Flux doesn't replace Redis for distributed locks, server-side job queues, or server-side sessions. Those stay on your backend exactly as they are today.
The Mutation Pipeline shapes and conditions client-side traffic before it leaves the device, deduplicating spam clicks, coalescing rapid edits. It doesn't stop a direct API call from Postman or curl. Rate limiting and DDoS protection stay server-side.
Flux runs entirely in the browser. It has no role in how your own backend services talk to each other, and makes no server-to-server calls on your behalf.
Wire transfers and direct debits must stay synchronous and server authoritative , never queued. The offline queue is for UI-layer mutations like preference changes, profile edits, and KYC updates, not ledger transactions.
Flux isolates the client-side cache by userId once an identity exists, it never establishes that identity. Session and auth validation remain entirely server-side.
Every tier ships the same offline-resilient core. Start free, stay free on localhost and preview deployments, and pay only once you're shipping features to production.
Core IndexedDB engine, SNAPSHOT/COLLECTION_ALL caching, and the offline write queue, production-ready from day one.
The full mutation pipeline, conflict resolution, and complete multi-tenant session security, everything Flux does, on a single production domain.
Same engine as Starter, unlocked across multiple production domains with 5x the event quota, for teams running more than one app off one key.
Everything in Pro, uncapped, for teams running at scale.
Free on localhost and preview deployments (*.vercel.app, *.netlify.app, *.pages.dev) — no console watermark in any dev environment.
Add the core engine, the Next.js plugin, and a realtime adapter to your workspace dependencies.
Wrap your existing Next.js config to inject the service worker and pre-warm dynamic route chunks.
Mount FluxProvider around your app to run hydrate() and register the service worker on boot.
