Exceptionless review
A flexible error-monitoring option for teams that value self-hosting and clear usage tiers.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Exceptionless is an open-source error and event monitoring platform for application developers and teams managing application reliability. It captures unhandled and handled exceptions, logs, feature-usage events, and other application data, then organizes them with grouping, notifications, trends, and detailed stack traces. Browser and JavaScript support, source-map processing, application version tracking, user-session tracking, and APIs extend its coverage beyond basic exception capture. It fits teams that want a hosted service or control over deployment through Docker and Kubernetes.
Pricing is organized around usage, retention, projects, and users. The Free plan costs $0 per month and includes 1 project, 1 user, 3 days of event retention, and 3,000 events per month, with no premium features. Small costs $15 per month for 5 projects, 10 users, 30 days of retention, and 15,000 events. Medium is $49 for 15 projects, 25 users, 90 days, and 75,000 events. Large costs $99 for unlimited projects and users, 180 days, and 250,000 events; Extra Large is $199 with the same project, user, and retention limits but 1,000,000 events. Enterprise costs $499 for 3,000,000 events and the same unlimited project, user, and 180-day structure.
The standout strength is breadth across errors, logs, events, releases, sessions, and stack management, combined with an event and project API. Slack, Zapier, and webhooks support notification and workflow connections, while Docker and Kubernetes options suit teams that prefer deployment control. Exceptionless is a good choice for developers who need self-hosting or want plans that scale from a small free deployment to higher event volumes. Teams needing more than 3,000 free events or longer free retention should plan for a paid tier.
