The simplest way to test your webhook.

Distributed ??? events and counting...

Listen to an internet webhook locally

Easily create and listen to webhooks calls from the internet! Use either the existing Ubsub CLI Client, or write your own listener using SocketIO, to get a URL on the internet that you can receive locally.

Forward webhook to an internal service

Use UbSub to forward an external URL to an internal endpoint quickly using the Ubsub CLI Client.



Communicate with different protocols such as HTTP, Email, SocketIO, UDP, and MQTT. Easily connect anything to everything.

Common Language

UbSub communicates with the most common language on the internet: JSON

Many Use Cases

Because there are so many protocols, it covers a variety of use-cases such as low-power IoT devices, 3rd party platforms, web browers, or your own internal systems.

Validation & Transformation

Manipulate and validate your payload and translate it to something your subscriber understands without the hassile of managing servers.

Separate Concerns

No need to have one service need to know about another. Centralize service interaction and communication through UbSub.

Simple Data Store

Persist simple variables to keep track of state between event publications.

Cron Jobs

Schedule tasks to kick off events, check service health, or poll for data.
