API monitoring, made for developers

Know when your API goes down.

Monitor API health automatically, catch unexpected responses, and inspect HTTP requests — all from one simple dashboard.

Built for developers. Simple to set up. Easy to understand.

Everything you need to keep your APIs healthy.

Designed around what developers actually check — status, latency, and history. No fluff.

Automated API Monitoring

Monitor endpoints automatically at user-configured intervals and detect unexpected HTTP responses.

Live API Testing

Send GET and HEAD requests to public endpoints and inspect status codes, latency, content type, and previews.

Response History

Review previous health checks, response codes, latency, and failures to understand what happened.

Custom Health Expectations

Define the expected HTTP status code for each monitor so an unexpected response is flagged as unhealthy.

One Dashboard

Manage multiple monitors, inspect their latest status, and review historical results from one place.

Developer-Friendly

A clean interface designed around the information developers actually need, without unnecessary complexity.

From endpoint to insight in seconds.

No SDKs, no agents. Just your URL.

01 — ADD AN ENDPOINT

Enter the API URL

Choose the monitoring interval (60–86400s) and specify the expected status code.

02 — LET goodAPI CHECK IT

Backend sends HTTP requests

Initial test runs on creation. Results are stored with latency and status. No background scheduler yet — history grows with each test.

03 — REVIEW THE RESULTS

See health, latency, history

Dashboard shows healthy/failed states, response codes, and previous checks from one place.

Built for how you debug APIs.

Same Graphite Edge design as your dashboard — compact, technical, readable.

Your APIs deserve better visibility.
