Application observability

Traces, users and logs — on your servers.

Instrument services with OpenTelemetry and see every request across your stack. Add real user monitoring and session replay for the browser, SDKs for mobile apps, and fast log search — without per-GB ingest pricing.

Answer

Kllyroo APM ingests OpenTelemetry traces to build service maps, latency and error views, SLOs with error budgets and burn alerts, continuous profiling flame graphs and an errors inbox. RUM captures Web Vitals and masked session replays; mobile SDKs cover Android, iOS, React Native and Flutter; logs support search, live tail, pipelines and storage tiers.

Capabilities

What you get

APM services & traces

OpenTelemetry services, distributed traces and an automatic service map.

SLOs & error budgets

Define objectives, track error budgets and get burn-rate alerts before users notice.

Continuous profiling

Flame graphs, diffs and regression detection to find the code that got slow.

Real user monitoring

Web Vitals, pages, API calls and masked session replays of real visitors.

Mobile & LLM monitoring

Crashes, ANRs and symbols for mobile apps; tokens, cost, latency and quality of LLM calls.

Logs

Log explorer, live tail, pipelines and storage tiers — measured at ~14,000 lines/s end-to-end ingest.

Logs

Search millions of lines — no ingest bill

Logs land on your own storage, so a noisy week never turns into a surprise invoice. The AI engine learns normal log volume and flags error bursts automatically.

  • Live tail and saved views
  • Pipelines to parse and enrich
  • Storage tiers and retention you control
  • Business journeys: UPI / payment / order KPIs from real transactions
