Know exactly where your
APIs are slow, broken,
and expensive
Flowlitic gives backend and fullstack developers a unified dashboard for latency, errors, and cost — per API endpoint. In minutes, not days.
// Node.js — 3 lines to start monitoring
const { Flowlitic } = require('flowlitic');
Flowlitic.init({ apiKey: process.env.FLOWLITIC_KEY });
// That's it. Every API call is now tracked.Everything you need to understand your APIs
Three core pillars that give you complete visibility into performance, reliability, and cost.
Latency & Performance
P50, P95, P99 breakdowns per endpoint. Spot slow dependencies before they tank user experience. Drill into individual requests with full timeline traces.
< 1ms overheadError Rates & Failures
Real-time error rate monitoring with intelligent alerting. See failure patterns across services, correlate errors with deploys, and get notified instantly.
Instant alertsCost Analytics
Track exactly what you spend on every third-party API call — Stripe, OpenAI, Twilio, and 200+ others. Identify cost spikes before they hit your bill.
