Rollbar

Rollbar is a real-time error monitoring and crash-reporting platform that helps developers catch, diagnose, and fix errors across their applications. It captures exceptions and crashes from web, mobile, and backend code as they happen, groups similar errors intelligently, and provides stack traces, request data, and telemetry so engineers can quickly find root causes. Instead of learning about problems from user complaints, teams get real-time alerts and a clear feed of what is breaking, where, and how often — reducing time to detect and resolve issues.

The platform focuses on fast, actionable error resolution. Intelligent grouping cuts noise by clustering duplicate errors; deploy and version tracking ties errors to releases; and telemetry and (on some tiers) session replay give context around each error. Rollbar supports many languages and frameworks via SDKs, integrates with alerting and workflow tools (Slack, PagerDuty, Jira, GitHub), and adds AI-assisted triage and grouping to speed diagnosis. Its all-tiers unlimited-users model means adding engineers does not raise the bill, with pricing scaling by monthly event volume.

Rollbar serves software engineering teams that need to monitor and fix application errors. It offers a Free plan (up to 5,000 events/month, 30-day retention), an Essentials plan starting around $29/month, an Advanced plan starting around $129/month (scaling with event volume, session replays, and AI credits; larger deployments often $500–$1,000+/month), and custom Enterprise — with unlimited users on all tiers and a 14-day full-access trial. It competes with Sentry, Bugsnag, Datadog, and Raygun, differentiating on real-time error grouping with unlimited users and event-based pricing.
