Ping
ICMP ping a host to verify basic network reachability and latency.
50 monitors free forever
Know when your site, APIs, or services break—before customers do.
Start free with up to 50 monitors for websites, APIs, ports, and hosts. Invite your whole team, publish a basic status page, and add scripted or AI-generated workflows when uptime alone is not enough.

Explore synthetic monitoring →Built for the teams responsible for reliability
Meet each team where its monitoring work already starts.
Reuse existing automation, start with practical checks, and keep investigation and communication in the same workflow.
QA and automation teamsTurn Playwright, Postman, Selenium, and Puppeteer tests into continuous production checks.
SaaS engineering teamsCover customer-critical login, checkout, billing, API, and background-job workflows without assembling separate tools.
Platform and DevOps teamsRun checks from public regions or private networks and connect failures to alerts, incidents, and maintenance.
Agencies and service providersOrganize customer monitors, give teammates access, and publish separate branded status pages for the audiences you support.
Built for modern operations
One place to detect, diagnose, and communicate production issues.
Most teams need more than a green or red badge. Testable combines practical monitor types, clear failure evidence, incident workflows, notifications, maintenance windows, and status pages so the response is as reliable as the check.
Check what mattersUse lightweight uptime checks or deeper browser, API, heartbeat, and scripted monitors.
Debug fasterCapture the context engineers need: timing, assertions, logs, traces, screenshots, and history.
Run where it countsUse our public runners or self-host your own inside the networks you need to observe.

Monitor types
Start with uptime. Grow into real workflow monitoring.
Pick the lightest check that proves the signal you need, then move up to AI-native or scripted flows when a simple ping is not enough.
TCP
Port Monitor
Connect to a host on a specific TCP port to make sure the service is accepting connections.
HTTP
HTTP
Check an HTTP or HTTPS endpoint with custom headers, response validation, and timing requirements.
HB
Heartbeat
Ensure that a service or cluster is alive, or that a cron job finished and reported back on schedule.
AI
AI Agent
Describe browser steps in plain language and let an AI agent run the first check. Testable saves the generated script for future runs, then regenerates it only when the flow needs to change.
FX
Scripted Flow
Script custom website or API flows with Playwright, Puppeteer, Selenium, Postman, Node.js, Python, Locust, JMeter, Gatling, and more.
Testable (demo@testable.io)
Create a monitor that loads https://testable.io in a browser, checks that the title contains "Testable", and takes a screenshot. Run it every 15 minutes.
Testable AI
I can create that as an AI-generated Playwright monitor. I will smoke test the script first so future checks can reuse it without asking AI every time.
Created scenario, ran smoke test, and saved monitor 37.5s
Created a browser Playwright monitor.
- Scenario created: testable.io title + screenshot
- Smoke test passed and captured a screenshot
- Schedule: every 15 minutes from AWS EU Ireland
Testable (demo@testable.io)
Setup a heartbeat monitor for my new service cluster with 4 nodes, with at least 2 of them up to be considered healthy.
Testable AI
Got it. I will treat the cluster as healthy when any two sources report in on time, and I will generate a separate heartbeat URL for each node.
Testable (demo@testable.io)
Add email and Slack notifications for critical alerts.
Created cluster heartbeat monitor and alert policy 5.8s
Created a cluster-level heartbeat monitor.
- Healthy quorum: at least 2 of 4 active nodes
- Expected ping interval: 60 seconds
- Heartbeat URL generated with source per node
POST https://heartbeat.testable.io/... ?source=node-01

AI native monitoring + MCP
Use AI Conversations for monitoring operations, investigation, and automation.
AI Conversations live in the Monitoring app for doing anything you can do in the web app: creating and updating monitors, status pages, and maintenance windows, plus investigating and analyzing failures. For AI agent checks, Testable can run the flow once, capture the generated script, and reuse it on future checks. You can do the same kind of work from an external AI client by connecting Cursor, Cline, or another MCP client to Testable through Model Context Protocol.

Operations workflows
Everything around the check matters too.
Monitoring is not only the probe. Testable also gives teams the workflow pieces they need to communicate, pause expected noise, and respond when something breaks.
Maintenance windowsSchedule planned downtime so expected outages do not create noisy incidents or customer confusion.
Incident managementTrack current and historical incidents, resolution status, root cause details, and customer-facing updates.
NotificationsReach the right people through email, voice, text, WhatsApp, webhooks, Slack, and Microsoft Teams.
Enterprise compliance
Built for teams with real security and privacy requirements.
Testable supports enterprise procurement and privacy review with controls and programs aligned to ISO 27001, GDPR, and CCPA expectations.
ISO 27001

CCPA
Start with one workflow customers depend on.
Create a monitor, choose where it runs, and connect the people and status page that should respond when it fails.
