Best Free Pusher Alternatives in 2026
Break past the 100 concurrent connection ceiling with native Server-Sent Events (SSE), webhook relays, and real-time messaging APIs.
Strict 100 concurrent connections limit on the Sandbox plan and steep pricing tiers ($49 - $499/mo) as active tabs grow.
Live SSE-powered FreeAPI Webhook channels, high-throughput Discord/Telegram event streams, and open real-time endpoints.

| Live Event Payload Inspector | Requires account sign-in for Debug Console | Anonymous, instant Live Webhook Tester |
| Billing & Lock-In | Forced $49/mo upgrade at 101st connection | Zero credit card, open standard protocols |
