About
Scaledrone is a realtime messaging service that provides WebSocket-based pub/sub messaging, message history, and user presence for applications that need live updates. The service supports publishing messages, subscribing to rooms, and fallback transport handling when WebSockets are not available.
The free plan includes up to 20 concurrent connections and 100,000 events per day. It is suitable for chat, collaboration, presence indicators, live dashboards, realtime charts, and other apps that need a managed realtime backend with usage caps that refresh daily.

Free Tier Value
This free tier is a capped but genuinely usable plan: it includes all product features, and the only limits are 20 concurrent connections and 100,000 events per day. The cheapest paid plan is $19/month for 100 connections and 200k events/day, so the free plan is roughly half of that practical capacity and is worth about $19/month. No credit card is required, and the offer is perpetual rather than a short trial.
What's included in the free tier
- Access to 20 concurrent connections.
- Access to 100,000 events per day.
- All product features included on the free plan.
