Why teams switch

Pusher's protocol. Better bill.

Vask speaks the format you already use. Point your client at wss.vask.dev and ship - same SDKs, same channels. New bill.

1 msgN clients

FEAT.01

No fan-out fees

One broadcast = one message, no matter how many subscribers receive it. Pusher charges per delivery - we charge per publish.

- PUSHER_HOST=ws-eu.pusher.com
+ PUSHER_HOST=wss.vask.dev
// the rest of your code: untouched

FEAT.02

Drop-in compatible

Any Pusher SDK works unmodified. Migrate by changing three env vars. Keep your channels, presence, auth callbacks.

"I built Vask for me, it's everything I've needed for all of my side projects. I don't want to manage infra, I don't want to pay $50/mo, and I don't want to worry that if my project is successful my bill will jump to $2,000/mo. Pusher's protocol is great. The pricing just grows too fast."

FAQ

Questions you might be asking.

Yes. We implement the Pusher protocol on the wire. Any Pusher SDK - JS, PHP, Python, Ruby, .NET, Swift, Android - works without modification. Point it at wss.vask.dev and your existing channel/event/presence keeps working.
Every account starts on the Free Tier: 500,000 server broadcasts per month and 100 concurrent connections, shared across unlimited apps. No credit card. Upgrade when you need more headroom.
Nothing breaks. We don't throttle, drop messages, or block you. We email you, give you enough time to either right-size or move up a tier. We will never surprise-bill you mid-month.
P99 sub-50ms within region, served from Cloudflare's edge in 330+ cities.
Update two env vars (app id, host), drop in your Vask app key, redeploy. Most teams ship the migration in under an hour.
