DeadBro vs. Skylight:
Rails APM Comparison
Skylight is beautifully simple and Rails-aware — a great starting point. But as your app grows, you'll hit its limits: no error tracking, no uptime monitoring, no memory profiling, no Redis tracing. DeadBro picks up exactly where Skylight leaves off.
Skylight is excellent for understanding which endpoints are slow. DeadBro is built for teams that need to know exactly why — down to the view partial, the Redis pipeline, the leaking heap, and the exception that triggered it. Same simplicity, significantly more depth.
Six key advantages
over Skylight
Error Tracking Included
Skylight has no error tracking. DeadBro includes full exception capture with stack traces, user context, request params, and smart grouping — so you see errors and performance data in one place.
Built-in Uptime Monitoring
Skylight has no uptime monitoring. DeadBro includes "Is It Dead" uptime checks with custom HTTP methods, pause/resume, and instant Slack alerts when your app goes down.
Memory Leak Detection
Skylight provides no memory profiling. DeadBro tracks heap pages, garbage collection cycles, and memory allocation patterns over time — critical for catching leaks before they OOM-kill your dynos.
Redis Pipeline Tracing
Skylight does not trace Redis operations. DeadBro provides full pipeline and transaction-level visibility into your Redis calls, helping you tune your caching strategy with real data.
Automatic SQL EXPLAIN ANALYZE
Skylight groups queries but does not run EXPLAIN ANALYZE. DeadBro automatically surfaces the database execution plan for every slow query, directly in the dashboard.
User Activity Tracking
Skylight has no per-user tracking. DeadBro ties every request, error, and N+1 query to a specific user — so when someone reports "the app is slow," you can look up exactly what they experienced.

Why Rails developers
choose DeadBro
01Full Observability, Not Just APM
Skylight is a focused APM tool. DeadBro adds error tracking, uptime monitoring, user activity, and memory profiling — so you have a complete picture without stitching together multiple services.
02Deeper Query Analysis
Beyond slow query detection, DeadBro runs EXPLAIN ANALYZE automatically and flags N+1 patterns visually — helping you go from "this is slow" to "here is the fix" in minutes.
03Memory Profiling for Rails
Heap page tracking, GC cycle analysis, and object allocation patterns over time help you catch memory leaks before they become OOM kills — something Skylight simply does not provide.
04Per-User Performance Data
DeadBro ties every request and error to a specific user identity, making it trivial to reproduce user-reported issues and understand the exact performance a specific user experienced.
Simple, transparent pricing
Pay for what you use. No hidden fees for extra containers or servers.
