Checkend

What Checkend is

Checkend is self-hosted error monitoring software with a dashboard for tracking application errors. Automatic fingerprinting groups similar problems, and teams can also define custom fingerprints. Notifications can be routed through email, Slack, Discord, webhooks, or GitHub Issues, with rules set for each app. Team features include role-based access, email invitations, and assigning apps to particular teams. A REST API with fine-grained permissions supports managing apps, problems, teams, and users. Checkend supports frontend monitoring and source maps, with listed Ruby integrations for Rails, Sinatra, Rack, Sidekiq, and Resque; one Ruby SDK serves web apps and background jobs. The Python error reference describes capture with tracebacks, request data, and other context. Deployment uses Docker and PostgreSQL, without requiring Redis, and error data stays on the user's servers. The source is available under the O'SASSY License. The Free plan is free, billed Forever, with no subscriptions or per-event fees.
