BigState vs Pusher

See how a managed versioned-state platform compares to Pusher Channels — a hosted pub/sub messaging service — and when BigState is the better fit.

What is BigState?

BigState is a managed platform for sharing versioned object state between applications, people, and AI. Publish over HTTP, store authoritative snapshots, authorize with principals and policies, and deliver matching updates over WebSocket — without running your own realtime mesh.

What is Pusher Channels?

Pusher Channels is a hosted pub/sub messaging service for realtime UI updates. Servers trigger events on named channels; clients subscribe over WebSocket (with HTTP fallbacks). Private and presence channels add access checks and online membership on top of that event model.

Compare BigState and Pusher Channels

Includes where BigState is stronger and where both are a solid fit. Omits rows where Pusher alone would win — those belong in a different comparison, not this one.

Realtime basics

  • Live push to connected clients

    UIs and workers need updates without polling.

    BigStateYes

    WebSocket deliveries push matching state updates as soon as publishers set new versions.

    Pusher ChannelsYes

    Clients subscribe to channels and receive triggered events in realtime over WebSocket with HTTP fallbacks.

  • Automatic reconnect

    Mobile and flaky networks drop connections constantly.

    BigStateYes

    Clients reconnect and can re-attach to deliveries; pair with a latest-state fetch to stay authoritative.

    Pusher ChannelsYes

    Official clients reconnect and resubscribe; you still decide how to restore application state after a gap.

  • Ordered updates

    Out-of-order patches make counters and timelines wrong.

    BigStateYes

    Each set creates a new versioned snapshot — consumers reason about order via versions and timestamps.

    Pusher ChannelsYes

    Events on a channel are delivered in publish order for connected subscribers.

  • Client SDKs & frameworks

    Teams ship in different stacks — browsers, frameworks, and backend languages.

    BigStateYes

    Core JavaScript client plus React, Vue, and Angular helpers; HTTP examples and APIs for Python, Go, Java, C#, and more.

    Pusher ChannelsYes

    Broad client and server libraries for web, mobile, and many backend languages.

  • Group consumers (channels / rooms)

    You need a way to target subsets of listeners.

    BigStateYes

    Delivery channels select which objects a subscriber receives.

    Pusher ChannelsYes

    Named public, private, and presence channels are the primary way to fan out events to groups of clients.

Getting started

  • Try without a large commitment

    Teams want to prototype before buying or building infra.

    BigStateYes

    Create an API key and use the managed cloud to publish and subscribe quickly.

    Pusher ChannelsYes

    Sign up for a Channels app and use the free sandbox to publish and subscribe quickly.

  • Self-host when you must

    Some environments require running software on your own infrastructure.

    BigStateYes

    Managed cloud by default; self-hosted deployment is available (contact sales).

    Pusher ChannelsNo

    Channels is a hosted SaaS product. You do not run the messaging mesh on your own servers.

  • Operational visibility

    You need to see what is connected or configured while debugging.

    BigStateYes

    Dashboard for objects, principals, policies, and deliveries.

    Pusher ChannelsYes

    Channels dashboard shows connections, publishes, and subscriptions; webhooks and metrics export are available.

Core model

  • Versioned state as the product

    Apps need an authoritative current value — not only fire-and-forget events.

    BigStateYes

    Objects hold timestamped, versioned state. Clients can always get the latest snapshot (or a past version) over HTTP, then subscribe for live updates.

    Pusher ChannelsNo

    Channels delivers events on named channels. It does not store an authoritative object model — you persist “current value” elsewhere.

  • HTTP publish + realtime deliver

    Backends already speak HTTP; subscribers need push without polling.

    BigStateYes

    Trusted services set state via the HTTP API. Delivery channels push matching updates to WebSocket subscribers.

    Pusher ChannelsYes

    Server SDKs trigger events over HTTP to Channels; subscribed clients receive them in realtime.

  • Catch up after disconnect

    Users and workers reconnect constantly — missed updates must not leave UIs stale.

    BigStateYes

    On reconnect, get the latest state, then resume delivery. Historical versions remain available per object configuration.

    Pusher ChannelsPartial

    Cache channels can retain a last triggered event for late subscribers. Full history and authoritative rebuild still require your own store.

  • Inline JSON and binary payloads

    Dashboards need metrics; humans and apps also share files and images.

    BigStateYes

    Publish JSON, numbers, or strings inline, or upload binary values and attach them with valueRef.

    Pusher ChannelsPartial

    Events carry JSON payloads within size limits. File storage, URLs, and versioned binary objects are not part of Channels.

  • Typed objects as a stable contract

    Producers and consumers need an agreed shape — not ad-hoc event names forever.

    BigStateYes

    Define objects with types and metadata once. State updates follow that contract; clients always know what “current” means.

    Pusher ChannelsNo

    Channels and events are names plus payloads. Schema and compatibility are conventions you invent on top.

  • Efficient mutations (patch / increment)

    Counters and partial JSON updates should not require rewriting the full value every time.

    BigStateYes

    Set state with mutation.patch or mutation.incrementBy when you do not need a full replacement.

    Pusher ChannelsNo

    No built-in state mutation model. You trigger events and apply patches in your own store.

  • State validity / freshness window

    Stale readings should be detectable — especially for sensors, locations, and live metrics.

    BigStateYes

    Configure validity on objects so consumers can reason about whether the latest state is still current.

    Pusher ChannelsNo

    No first-class freshness semantics. Expiry and “is this still true?” logic live in your app.

Delivery & routing

  • Configurable delivery channels

    Each consumer should receive only the objects it needs.

    BigStateYes

    Create deliveries that select objects and push updates to the right subscribers — one model for apps, UIs, and agents.

    Pusher ChannelsPartial

    Named channels route events, but object selection, versioning, and multi-resource fan-out rules remain application design.

  • Many consumers on the same object

    One published state should feed dashboards, services, and agents without duplicating writes.

    BigStateYes

    Publish once; multiple deliveries and readers attach to the same authoritative object stream.

    Pusher ChannelsPartial

    Many clients can subscribe to one channel, but each product still invents its own “current value” protocol beside the events.

  • Multi-node fan-out without DIY adapters

    Horizontal scale is where self-hosted transports get expensive to operate.

    BigStateYes

    BigState is a managed service: publish once and subscribers receive matching updates without Redis adapters or sticky sessions on your side.

    Pusher ChannelsYes

    Channels is managed infrastructure — you trigger and subscribe without running your own realtime mesh.

  • HTTP publishers without a sticky Node fleet

    Most backends — including serverless — already publish over HTTP.

    BigStateYes

    Any trusted service can set state with the HTTP API. You do not keep long-lived socket processes just to accept writes.

    Pusher ChannelsYes

    Server libraries trigger events over HTTP from ordinary backends and cloud functions.

Security & access

  • First-class principals, API keys, and tokens

    Every publisher and subscriber needs a scoped identity.

    BigStateYes

    Create principals with API keys or tokens as part of the platform model — ready for services, browsers, and agents.

    Pusher ChannelsPartial

    App keys and secrets authenticate your server to Pusher. End-user identity for private channels is an auth endpoint you implement.

  • Policy-based authorization

    Who may set or read which resources should be explicit and auditable.

    BigStateYes

    Policies match principals, actions, and resources so access stays scoped per object and environment.

    Pusher ChannelsPartial

    Private/presence subscribe requires a signature from your auth server. Fine-grained object policies are not a built-in product model.

Operations & reliability

  • Managed infrastructure

    Realtime meshes fail during deploys, reconnect storms, and hot channels.

    BigStateYes

    Run on BigState’s managed cloud (or contact sales for self-hosted). No socket fleet or Redis fan-out to babysit.

    Pusher ChannelsYes

    Channels runs as managed WebSocket infrastructure with dashboards, webhooks, and vendor-operated capacity.

  • Authoritative history for audits and rebuilds

    Debugging and late joiners need more than the last ephemeral event.

    BigStateYes

    Each set creates a new version. Keep depth via versionDeep and re-read any retained snapshot when you need it.

    Pusher ChannelsNo

    Channels is not a versioned state store. Cache channels keep a recent event; durable history is your database.

Built for apps, people, and AI

  • One model for applications

    Services should share live data without a bespoke sync bus per pair of apps.

    BigStateYes

    Applications publish and subscribe to versioned object state — the same foundation as humans and AI consumers.

    Pusher ChannelsPartial

    Apps can share channels for events, but each product still invents persistence and “what is current?” semantics.

  • Human-readable public states

    Reports, files, and dashboards need shareable latest versions — not only socket rooms.

    BigStateYes

    Curate public states with documents and media so people and apps read the same current version.

    Pusher ChannelsNo

    No concept of curated public object state. Sharing files and “latest report” semantics are custom product work.

  • Live context for AI agents

    Agents need fresh structured state — not a fragile side-channel of events.

    BigStateYes

    Connect agents to the same states apps and humans already publish — read latest or subscribe as values change. Expose the same operations through MCP tools when you wire an agent runtime.

    Pusher ChannelsPartial

    Agents can subscribe to channels, but you still build persistence, authz, and authoritative “current” semantics yourself.

  • Dashboard to manage objects and access

    Teams need to inspect streams, credentials, and policies without shipping a custom admin UI first.

    BigStateYes

    Use the BigState dashboard to work with objects, principals, policies, and deliveries as first-class resources.

    Pusher ChannelsPartial

    Channels dashboard covers connections and messaging activity. Product resources (state, files, policies) remain your application.

Build on versioned state — not just events

Publish once, authorize with policies, and deliver live updates to applications, people, and AI — without running a separate event-only messaging stack for state.
