Last updated on April 14th 2026
This week, we shipped a major upgrade to our online WebSocket client and the Chrome extension, Β focusing on multi-connection testing, better debugging tools, and improved developer experience.
β¨ New Features & Improvements
π Multi-Connection Testing
Run up to 3 simultaneous WebSocket connections in single, dual, or triple panel layouts. Easily compare responses across different environments without switching tabs.

Full support for both secure (wss) and unsecured (ws) protocols. Works seamlessly with any WebSocket server.
π Auto-Reconnect
Simulate real-world client behaviour with configurable auto-reconnect, including custom retry limits and intervals.
π Heartbeat / Ping Support
Keep connections alive using configurable heartbeat messages sent at regular intervals β ideal for testing server keep-alive logic.
π§ Message History
Quickly navigate previously sent messages using keyboard shortcuts. No need to retype payloads during iterative testing.
π§Ύ JSON Pretty-Print
Incoming messages are automatically formatted for readability. Switch between raw and pretty-printed JSON views instantly.
π Log Filtering & Search
Filter logs by type (sent, received, error, info) and perform real-time search across all messages.
π€ Export Logs
Download complete session logs as a timestamped .log file for sharing or debugging.
