Exceptionless
Exceptionless provides real-time error, feature, and log reporting for applications.
What Exceptionless is
Exceptionless provides real-time error, feature, and log reporting for applications. Applications can send events to a dashboard, where teams organize them with tags; the service groups exceptions, logs, and feature events into detailed reports with stack traces. It supports JavaScript, Node, .NET Core, ASP.NET, Web API, WebForms, WPF, Console, and MVC applications, with web, API, and self-hosted deployment options. Project configuration changes can reach clients in near real time without changing deployed application code. Exceptionless supports error-occurrence notifications, but free-plan notifications are limited to daily summaries. The free plan includes one project, one user, three days of event retention, and 3,000 events per month. Exceptionless is open source and can be self-hosted from its server and frontend source code or a Docker image; Kubernetes is also supported. The product says it uses SSL and offers data exclusions for specified fields in error reports.
