Realtime shouldn’t cost
you a sprint.
Self-hosting websockets means servers, scaling and on-call pager duty. Ressonance handles the operational weight so your team stays on product.
02 / NO LOCK-IN
Keep the SDK you already use.
Built on the Pusher protocol. Any Pusher-compatible client or server library works. No rewrite needed.
03 / NO SURPRISES
Start free. Scale as you grow.
Clear monthly tiers, no contracts, and room to grow as usage increases.

What exactly is Ressonance?+
Ressonance is managed realtime infrastructure built on the Pusher protocol. It lets you run channels, events and presence without running websocket servers yourself.
Do I just need a Pusher-compatible SDK?+
Yes. Point your existing Pusher-compatible server and client SDKs to Ressonance, then use your application credentials.
Why not just self-host?+
Self-hosting puts scaling, monitoring, deployments and incident response on your team. Ressonance keeps those concerns managed so you can focus on product.
How does it compare with Pusher?+
It is purpose-built for teams that want a familiar Pusher-compatible API, managed operations and predictable, developer-friendly pricing.
What about security?+
Connections are encrypted in transit and message payloads are not persisted by default.
Your realtime backend is three lines away.
Free forever for side projects. Upgrade as you grow.
