E11y (Easy Telemetry) - Observability for Rails developers who hate noise. UNIQUE FEATURES: • Request-scoped debug buffering - buffers debug logs in memory, flushes ONLY on errors • Zero-config SLO tracking - automatic Service Level Objectives for HTTP endpoints and jobs • Schema-validated events - catch bugs before production with dry-schema DEVELOPER EXPERIENCE: • Minimal setup — one config block, works with stdout out of the box • Auto-metrics from events (no manual Yabeda.increment) • Rails-first design (follows Rails conventions) • Pluggable adapters (Loki, Sentry, OpenTelemetry, custom backends) COST SAVINGS: • Reduce log storage costs by 90% (request-scoped buffering) • Replace expensive APM SaaS ($500-5k/month → infra costs only) • Own your observability data (no vendor lock-in) PRODUCTION-READY: • Thread-safe for multi-threaded Rails + Sidekiq • Adaptive sampling (error-based, load-based, value-based) • PII filtering (GDPR-compliant masking/hashing) • Performance optimized (hash-based events, minimal allocations) Perfect for Rails 7.0+ teams who need observability without complexity or high costs.
