Pusher Channels alternative for SaaS chat
Pusher's free tier works until it doesn't. If connection pricing is climbing faster than your app, room chat on Cloudflare with optional self-host is worth a look.
Why people leave Pusher
- Demo runs on the free tier; production traffic hits connection and message line items.
- Start on hosted beta; self-host on your Cloudflare account when you want cost control.
- You read Cloudflare DO/D1 pricing instead of guessing at a channels SKU.
Three paths
- Roll your own Socket.IO on a VM — full control, full ops.
- Pusher / Ably / Stream — fast start, vendor bill, less schema ownership.
- FluxyChat — room-per-DO on Workers + D1, MIT self-host or hosted beta, SDK with loadMore.
What Pusher threads complain about
- History and replay take extra work on Channels.
- Pricing at scale (connections, messages).
- Second vendor when the app already runs on Cloudflare.
Migration sketch
- Map channel names to roomIds.
- Mint JWTs server-side; client uses useChat.
- Keep Next on Vercel; Worker handles WS.
When to stay on Pusher
Generic pub/sub, telco-scale fan-out, or you need their dashboard tomorrow. FluxyChat is for tenant in-app chat where you want D1 history and the option to self-host.
Production next step
FluxyChat packages the same stack: RoomDurableObject, D1 history, multi-tenant JWT, reconnect-aware SDK, and operator console. MIT self-host or hosted beta.
