Sentry is the industry standard for error tracking, but their "Performance" feature charges per transaction, making it easy to burn through quotas. DeadBro gives you unlimited performance events for a flat monthly fee, plus automatic SQL EXPLAIN ANALYZE and deep Rails profiling. Stop rationing your traces.
Sentry charges for "transactions" (performance events). It's easy to burn through 100k events in a day with a busy app, forcing you to turn off performance monitoring to save money. DeadBro doesn't have a transaction quota. Send as many performance traces as your plan allows (5M+ requests) without fear, plus get automatic SQL EXPLAIN ANALYZE and deep Rails profiling included.
Predictability beats Pay-Per-Event. Six key advantages over Sentry.
Sentry users often turn off performance monitoring to save money. DeadBro is built to be always-on with flat-fee pricing. You shouldn't have to choose between saving money and seeing your performance data.
Sentry's performance tool is generic. DeadBro is built to understand Rails. We automatically highlight N+1 queries, view rendering times, Sidekiq queues, and run EXPLAIN ANALYZE on slow queries without custom instrumentation.
Errors, Traces, Replays, Attachments... Sentry's bill is a complex matrix of quotas and limits. DeadBro has one line item: Request Volume. Simple, predictable, and fair—no transaction quotas to worry about.
DeadBro automatically runs EXPLAIN ANALYZE on slow queries, showing execution plans without manual database access. Sentry doesn't offer this Rails-specific feature, requiring manual investigation.
DeadBro breaks down Rails view rendering at the partial and collection level, showing exactly which templates are slow. Sentry's generic performance tool doesn't provide this Rails-specific granularity.
DeadBro includes "Is It Dead" uptime monitoring as part of the platform—no extra cost. Sentry doesn't offer uptime monitoring, requiring you to use a separate service and pay additional fees.

Why Rails developers choose DeadBro over quota-based performance monitoring like Sentry.
DeadBro's flat-fee, request-based pricing means you can monitor all your performance events without worrying about quotas. Sentry's transaction-based pricing forces you to ration performance monitoring or face unexpected bills.
DeadBro's automatic EXPLAIN ANALYZE feature shows execution plans for slow queries without manual database access. Sentry doesn't offer this Rails-specific feature, requiring you to manually investigate slow queries.
DeadBro provides view partial-level rendering breakdowns, Redis pipeline tracing, and memory allocation tracking optimized for Rails. Sentry's generic performance tool doesn't provide Rails-specific granularity.
DeadBro has one line item: Request Volume. Sentry's complex pricing model (errors, traces, replays, attachments) makes it difficult to predict costs. With DeadBro, you know exactly what you'll pay each month.
Pay for what you use. No hidden fees for extra containers or servers.
