About DeadBro
What is DeadBro?
DeadBro is a Rails application performance monitoring (APM) tool that gives developers live traces, slow SQL detection, N+1 query alerts, and error tracking in a single dashboard. Instead of charging per host or machine, DeadBro bills based on tracked requests, so costs scale with actual traffic, not infrastructure size.
What problem does it solve?
Traditional APM tools often split features across multiple products, require complex setups, and price per host, leading to surprise bills when autoscaling kicks in. DeadBro solves this by offering a Rails-first product with automatic N+1 detection, full error stack traces, and real-time dashboards—all in one app, with billing that pools across apps and caps at your plan.
Who is it for?
DeadBro is ideal for solo Rails developers and small to mid-sized engineering teams who want deep Rails-specific performance insights without enterprise-level complexity or cost. It's not for teams needing multi-language APM or those requiring US-based data residency—DeadBro's EU-hosted infrastructure is a feature for privacy-conscious teams.
Real use cases
Track down a sudden spike in N+1 queries after a deploy, view per-user activity timelines to debug slow endpoints, and set Slack alerts for errors that fail silently. With automatic detection and request drill-down (SQL, cache, memory), you can explain performance issues to your team with exact line numbers and EXPLAIN plans.
Key features
- Automatic N+1 Detection — Flags N+1 queries in real-time with full query traces and exact line numbers, zero config.
- Rails Error Tracking — Full stack traces, request context, user info, and instant Slack notifications.
- Real-Time Dashboards — SQL performance, cache hit rates, memory patterns, and user activity in one live view.
- Request-Based Pricing — Billing tied to tracked requests, not machine count; no per-host fees.
- EU-Hosted Data — Telemetry stored on dedicated bare-metal servers in Europe, not on US hyperscalers.
- Open-Source Agent — 100% open-source agent with 5-minute setup via a Gem and initializer.
- Uptime Checks & Incidents — Built-in 'Is It Dead' uptime checks and incident management alongside APM data.
