What Exceptionless is
Exceptionless provides real-time error, feature and log reporting for applications. Apps can send events to a dashboard, where teams organize them with tags; the service groups exceptions, logs and feature events into reports with stack traces. It supports JavaScript, Node, .NET Core, ASP.NET, Web API, WebForms, WPF, Console and MVC applications, and is available through web, API and self-hosted deployments. Project configuration changes can reach clients in near real time without changes to deployed application code. The free plan includes one project, one user, 3,000 events per month and three days of event retention, with no premium features. Error occurrence notifications on that plan are limited to daily summaries. Paid plans start at $15 a month and include features such as searching, occurrence notifications, webhooks, Slack integration and Zapier integration. Exceptionless is open source and can be self-hosted using its server and frontend source code or a Docker image; Kubernetes is also supported. It says SSL is enabled out of the box and data exclusions can remove specified fields from error reports.
