Exceptionless Exceptionless

Build Discord Donate

The definition of the word exceptionless is: to be without exception. Exceptionless provides real-time error reporting for your JavaScript, Node, .NET Core, ASP.NET, Web API, WebForms, WPF, Console, and MVC apps. It organizes the gathered information into simple actionable data that will help your app become exceptionless!

We appreciate your star, it helps!

Using Exceptionless

Refer to the Exceptionless documentation.

Hosting Options

We provide very reasonably priced hosting at Exceptionless. By using our hosted service, you are supporting the project and helping it get better! We also provide set up and support services.

Exceptionless can be run locally as simply as docker run --rm -it -p 5000:80 exceptionless/exceptionless:latest. This will run a completely self-contained simple instance of Exceptionless. It is only suitable for testing purposes since it will not persist data. For more complete setups, check out the self hosting documentation. Also, if you want to support the project while self hosting you can send us a pull request or donation.


In appreciation for anyone who submits a non-trivial pull request, we will give you a free Exceptionless paid plan for a year. After your pull request is accepted, simply send an email to [email protected] with the name of your organization and we will upgrade you to a paid plan.
