Synthetic monitoring
Prove critical workflows work, not only that endpoints respond.
Start with HTTP, port, or ping checks, then add Playwright, Postman, or custom scripted workflows. Run publicly or inside your network and connect every failure to evidence, alerts, incidents, and status pages.
On Free, Ping, Port, and HTTP monitors have unlimited executions at a five-minute minimum interval. A separate 100-run monthly allowance covers advanced workflows; browser multipliers apply.
Upgrade for heartbeat monitoring, faster intervals, location choice, self-hosted sources, more scripted or AI runs, and longer retention.

What this monitor proves
Use the lightest check that proves the outcome you care about.
Testable supports basic availability signals and deep deterministic workflows, so teams can match monitoring depth to the risk of each system.
- 01
Availability checks
On Free, run Ping, Port, and HTTP checks as often as every five minutes with no monthly execution cap.
- 02
Workflow checks
Use the separate 100-run monthly Free allowance across supported scripted and AI-generated frameworks. Playwright and Puppeteer executions use 5 runs; Selenium uses 10.
- 03
Passive heartbeats
On paid plans, verify that jobs, workers, and service-cluster sources report on schedule.
login-flow Playwright every 5m 3 regions
checkout-api Postman every 1m private pool
order-workers Heartbeat every 60s 4 sources
public-site HTTP every 1m 5 regionsSetup
Start simple and deepen coverage where risk demands it.
Choose the customer or operational outcome, select a monitor type, run it from the right network, and define how confirmed failures should be handled.
- Map the outcome Identify the login, checkout, API, job, or private service that matters.
- Choose the check Use HTTP on Free, a paid heartbeat for passive signals, or a script for the complete workflow.
- Choose the source Use the assigned Free location or upgrade for location choice and self-hosted private sources.
- Close the loop Capture evidence, route alerts, manage incidents, and publish relevant status.
When a check fails
Get evidence your team can act on.
Testable connects the failed check to investigation, alerting, incident response, and customer communication.
Actionable diagnostics
Capture timing, assertions, screenshots, logs, traces, run history, and protocol details as appropriate.
Flexible confirmation
Use retries and thresholds to reduce noise before responders are notified.
End-to-end operations
Coordinate notifications, incidents, maintenance windows, and status pages without stitching together separate tools.
Common questions
What teams ask before they start.
What is synthetic monitoring?
It runs scheduled checks that simulate network, API, browser, or service behavior and verifies an expected result.
Can checks run inside a private network?
Yes. Assign monitors to self-hosted sources with access to private systems.
Can AI create a check?
Yes. Testable can generate and smoke-test the initial script, then reuse that deterministic script for future runs.
Build monitoring around the workflows customers depend on.
Create a basic check in minutes, then add deeper browser, API, or private-network coverage as your needs grow.
