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.
Free forever: 50 monitors, 1 basic status page, and unlimited teammates.

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 teams
Turn Playwright, Postman, Selenium, and Puppeteer tests into continuous production checks.
SaaS engineering teams
Cover customer-critical login, checkout, billing, API, and background-job workflows without assembling separate tools.
Platform and DevOps teams
Run checks from public regions or private networks and connect failures to alerts, incidents, and maintenance.
Agencies and service providers
Organize 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 matters. Use lightweight uptime checks or deeper browser, API, heartbeat, and scripted monitors.
- Debug faster. Capture the context engineers need: timing, assertions, logs, traces, screenshots, and history.
- Run where it counts. Use our public runners or self-host your own inside the networks you need to observe.
- Close the loop. Coordinate incidents, maintenance windows, notifications, and branded status pages.
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.
Ping
ICMP ping a host to verify basic network reachability and latency.
Port monitor
Connect to a host on a specific TCP port to make sure the service is accepting connections.
HTTP
Check an HTTP or HTTPS endpoint with custom headers, response validation, and timing requirements.
Heartbeat
Ensure that a service or cluster is alive, or that a cron job finished and reported back on schedule.
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.
Scripted flow
Script custom website or API flows with Playwright, Puppeteer, Selenium, Postman, Node.js, Python, Locust, JMeter, Gatling, and more.
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.

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.
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.

Setup a heartbeat monitor for my new service cluster with 4 nodes, with at least 2 of them up to be considered healthy.
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.
Add email and Slack notifications for critical alerts.

Status pages
Public status pages that stay connected to your real monitors
Publish one basic monitor-backed status page on Free. Paid plans add more pages, custom branding and domains, subscribers, incidents, maintenance windows, longer uptime views, metric charts, and detailed visibility controls.
- Custom domains and SSL. Use your own domain, auto-generate certificates, or provide your own TLS configuration.
- Display controls. Choose branding, layout, theme, font, colors, logo placement, uptime bars, and monitor detail visibility.
- Audience options. Password protect pages, manage subscribers, publish announcements, and control search engine visibility.
- Operational history. Show incidents, root cause details, overall uptime, monitor charts, and iCal exports for incidents and maintenance windows.
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 windows
Schedule planned downtime so expected outages do not create noisy incidents or customer confusion.
Incident management
Track current and historical incidents, resolution status, root cause details, and customer-facing updates.
Notifications
Reach 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
- GDPR
- 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.
