The most jarring difference between these two observability giants is not the feature set, but the shape of the invoice. Sentry asks for a flat subscription that covers a broad swath of monitoring, while Datadog presents a granular menu where every unit of data, every AI credit, and every specific monitoring capability is a separate line item. For a small team trying to budget, this distinction defines the entire purchasing decision. You are choosing between a predictable monthly fee that includes unlimited users and a modular system where costs scale precisely with your infrastructure's appetite for data.
The architecture of the cost
Sentry’s approach is straightforward. The Team plan is priced at $26/month and includes Unlimited users, API & third-party integrations, and 20 custom dashboards. If you need more control, the Business plan costs $80/month and adds Unlimited custom dashboards, Advanced quota management, and SAML + SCIM support. Beyond these core tiers, Sentry offers add-ons like Logs at $0.5, Uptime Monitoring at $1, Cron Monitoring at $0.78, UI Profiling at $0.25, and Continuous Profiling at $0.03. These are distinct, low-cost entries that allow you to extend functionality without jumping to a higher subscription tier.
Datadog, conversely, operates on a per-unit or per-feature basis that requires more attention to detail. Their catalog includes AI Credits at $1.3/month, which enable features like Bits Chat and Bits Investigation. Code Coverage is available for $12/month, providing unified visibility into test coverage. For logging, the pricing is broken down into Ingest at $0.1/month, Standard Indexing at $1.7/month, Flex Storage at $0.05/month, and Flex Logs Starter at $0.6/month. The platform also offers broader tiers like Pro at $18/month, Enterprise at $27/month, and Dev at $41/month. Application performance monitoring is segmented into APM at $48/month, APM Pro at $54/month, and APM Enterprise at $60/month. This structure means that a Datadog bill can be tailored to include only the specific components an engineering team needs, such as just the log ingestion and storage, without paying for unused AI or development features.

The decision ultimately hinges on whether your team values simplicity or granularity. If your primary need is error tracking and you want a single, predictable bill that covers unlimited users, Sentry’s Team or Business plans are the logical choice. They remove the complexity of metering and provide a clear ceiling on costs. However, if your infrastructure generates high volumes of logs or you require specific enterprise features like SAML and SCIM without committing to a full-stack platform, Datadog’s modular pricing offers a path to pay only for what you use. For data-heavy operations that need long-term retention, Datadog’s Flex Storage at $0.05/month is a compelling option for managing costs. For smaller teams focused on stability and ease of management, Sentry’s flat-rate model provides a more straightforward financial forecast. Choose Sentry for the all-in-one simplicity; choose Datadog for the ability to cherry-pick specific observability capabilities.
