Exceptionless
What it is
Exceptionless provides real-time error, feature, and log reporting for applications through web, API, and self-hosted deployments. Applications send events to a dashboard, where teams can tag and organize them. The service groups exceptions, logs, and feature events into reports that include stack traces. It supports JavaScript, Node, .NET Core, ASP.NET, Web API, WebForms, WPF, Console, and MVC applications. Project configuration changes can reach clients in near real time without changing deployed code. The free plan includes one project, one user, three days of event retention, and 3,000 events per month, with no premium features and error notifications limited to daily summaries. Paid plans start at $15 a month and add searching, occurrence notifications, webhooks, Slack, and Zapier integrations. Exceptionless is open source, supports Docker and Kubernetes self-hosting, uses SSL out of the box, and offers field-level data exclusions.
