Sentry

Sentry is an application monitoring and debugging platform developed by Functional Software, Inc. It helps development teams detect errors, investigate performance problems, and connect production issues with application context.

The platform collects telemetry through SDKs for web, mobile, desktop, server, serverless, and game applications. Its product areas include error monitoring, tracing, logs, session replay, profiling, release health, uptime monitoring, and cron monitoring.

Sentry began as an open-source project and maintains an open-source codebase alongside its hosted service. The company is headquartered at 45 Fremont Street in San Francisco and reports offices in Vienna and Toronto.

Sentry groups related errors into issues and provides stack traces, breadcrumbs, tags, release data, user context, and environment details. Teams can assign issues, configure ownership rules, and receive alerts through email and connected tools.

Performance features support transaction monitoring, distributed tracing, application metrics, continuous profiling, and UI profiling. Session Replay records user interactions for supported web and mobile projects, helping teams investigate crashes and frontend problems.

Additional capabilities include release health, user feedback, attachments, size analysis, uptime checks, cron monitoring, custom dashboards, logs, and anomaly detection. Sentry also offers Seer, an AI debugging agent that can analyze issue context and generate proposed fixes or pull requests when configured with the required integrations.

Supported integrations include GitHub, Slack, Jira, Microsoft Teams, and custom integrations. The platform provides a public web API, OAuth 2.0, authentication tokens, SDK APIs, and integration APIs.

Sentry uses a usage-based pricing model with a base subscription quota and additional pay-as-you-go charges. The Developer plan is free for one user and includes error monitoring, tracing, email alerts, ten custom dashboards, and MCP access.

The Team plan starts at $26 per month and adds unlimited users, API access, third-party integrations, twenty dashboards, and access to additional events. The Business plan starts at $80 per month and adds unlimited dashboards, advanced quota management, SAML, and SCIM.

Enterprise pricing is quote-based. Some capabilities, including Seer, continuous profiling, and UI profiling, can require additional usage-based charges. A free plan is available; the public pricing page does not state a universal paid-plan trial duration.

Sentry combines error tracking, performance analysis, tracing, replay, profiling, and release data in one developer-focused platform. Its broad SDK coverage supports many application architectures and programming languages.

The usage model gives small projects an accessible entry point, but event, replay, log, span, and profile volumes can increase costs as applications grow. Product depth can also create a steeper learning curve for teams that only need basic error reporting.

Comparable products include Datadog, New Relic, Dynatrace, Bugsnag, Rollbar, Honeycomb, Elastic Observability, and Firebase Crashlytics. Sentry is most directly comparable to Bugsnag and Rollbar for error monitoring, and to Datadog, New Relic, and Dynatrace for broader observability.
