Full Feature Set

Every tool you need to understand your APIs

From the first slow request to a monthly cost report, Flowlitic covers the full observability stack — without the Datadog price tag.

Know which endpoints are slowing you down

Latency & Performance Monitoring

Flowlitic tracks p50, p95, and p99 latency for every API call your application makes. Drill into any endpoint and see the full distribution of response times, broken down by time window, geography, or service dependency.

  • Per-endpoint latency percentiles (p50, p95, p99)
  • Historical trend charts with configurable time windows
  • Slow-request drill-down with full request metadata
  • Latency regression alerts — get notified when an endpoint degrades
  • Dependency maps showing upstream service performance
  • Baseline comparison: this week vs. last week

Surface failures before your users do

Error Rate & Failure Pattern Tracking

See error rates, 4xx/5xx distributions, and failure patterns across all your third-party API calls. Flowlitic groups similar errors automatically so you can triage systemic issues in seconds instead of digging through logs.

  • Real-time error rate dashboards per endpoint
  • 4xx / 5xx breakdowns with status code frequency
  • Automatic error grouping by message and stack pattern
  • Failure rate alerting with configurable thresholds
  • Timeline view linking spikes to deploys or config changes
  • Retry and timeout analysis

Stop overpaying for third-party API calls

API Cost Analytics

Track exactly how much each third-party API integration costs you — per call, per endpoint, per user, per day. Flowlitic surfaces cost anomalies automatically so you can optimize spend without manual analysis.

  • Per-call and per-endpoint cost attribution
  • Cost trend charts by API provider, service, or team
  • Anomaly detection for unexpected cost spikes
  • Usage vs. cost efficiency metrics
  • Budget threshold alerts via email or Slack
  • Monthly cost forecasting based on current trajectory

Instrument once, monitor everything

SDK & Reverse Proxy Integration

Flowlitic ships a lightweight SDK for Node.js, Python, and Go, plus a zero-code reverse proxy option for teams who don't want to touch their application code. Both paths add under 1ms of overhead.

  • Node.js SDK with automatic HTTP client patching
  • Python SDK supporting requests, httpx, and aiohttp
  • Go SDK with net/http transport wrapping
  • Reverse proxy mode — no code changes required
  • OpenTelemetry-compatible trace export
  • Framework adapters: Express, FastAPI, Gin, Next.js

Be the first to know, not the last

Alerting & Incident Notifications

Set smart alert rules on any metric — latency, error rate, cost spike, or availability. Notifications land in Slack, PagerDuty, or email within seconds of threshold breach.

  • Alert rules on any tracked metric
  • Slack, PagerDuty, and email integrations
  • On-call routing with escalation policies
  • Alert suppression during known maintenance windows
  • Anomaly detection mode — no manual thresholds needed
  • Runbook links attachable to each alert

One view for your entire API surface

Unified API Dashboard

Flowlitic's dashboard aggregates all your API flows into a single, searchable interface. Filter by provider, endpoint, team, or time — no query language required.

  • Real-time feed of all outbound API calls
  • Searchable endpoint explorer with filtering
  • Team and service-level breakdown
  • Custom dashboard widgets with saved filters
  • Request replay for debugging
  • API health scorecard per provider
