Open-source testing, monitoring, and AI SRE – as code

Test with Playwright and k6 and monitor your sites and APIs. When a check fails, Supercheck opens an incident, lets you investigate it with AI that cites its evidence, and keeps your users informed on a status page. Self-host today, or join the Cloud waitlist.

Platform

One place for the work between deploy and incident

Most teams stitch together a test runner, an uptime service, an incident tool and a status page. Supercheck covers all four, sharing one set of projects, alerts and history.

01
Check
A monitor or scheduled job with alerts on fails past its threshold.
02
Alert
Your notification channels get the failure.
03
Incident
An incident opens for that source, with its alerts attached.
04
Investigate
Run an AI SRE investigation that cites what it found. You decide the fix.
05
Recover
The check passes, a recovery is sent, and an unacknowledged incident resolves.

Automate

Write, record and run end-to-end and load tests.

Playwright browser, API and database tests
k6 load tests with streaming logs and run comparison
Scheduled jobs that run from cron or your CI pipeline
Recorder extension for Chrome and Edge
Requirements with coverage tracking

Monitor

Know when something breaks before your users tell you.

HTTP, website, ping and port checks
Checks from several regions, including Europe, North America and Asia Pacific on Cloud
Synthetic monitors that replay Playwright journeys
Failure and recovery thresholds to cut noisy alerts

Monitor docs

Monitors list with HTTP, website, ping, port and synthetic monitors

Respond

Monitor and job alerts open an incident you can work from (on by default, per check).

One incident per failing source, resolved on recovery unless someone has acknowledged it
AI SRE investigations that cite their evidence
Copilot chat and a service catalog for ownership and context
Read-only connectors for GitHub, Kubernetes, Prometheus, Grafana, Sentry and Datadog
Private Agent for systems inside your network

Communicate

Tell your team first, then tell your users.

Notifications by email, Slack, Teams, Discord, Telegram and webhooks
Public status pages on your own domain
Email, Slack and webhook subscribers, plus RSS and calendar feeds

Communicate docs

Public status page with an active status update and 90 days of uptime per component

Solutions

Built for the people who keep software working

See how developers, SRE and platform teams, QA engineers and engineering leaders use Supercheck.

As code

Keep tests and monitors in your repository

Define Playwright and k6 tests, monitors and scheduled jobs in one TypeScript file. Review changes in pull requests, then apply them from your terminal or CI pipeline.

Command	What it does
supercheck pull	Export what already exists in a project
supercheck diff	Preview what a deploy would change
supercheck deploy	Apply the configuration

Ask your AI tools about it

A read-only MCP server lets Claude, Cursor, VS Code and other MCP clients look at a project's tests, runs, monitors and incidents. Off by default when self-hosting.

CLI documentation MCP server

supercheck.config.ts

import { defineConfig } from '@supercheck/cli'

export default defineConfig({
  schemaVersion: '1.0',
  project: { organization: '<org-id>', project: '<project-id>' },
  tests: {
    playwright: { testMatch: '_supercheck_/playwright/**/*.pw.ts' },
    k6: { testMatch: '_supercheck_/k6/**/*.k6.ts' },
  },
  monitors: [
    {
      name: 'API health',
      type: 'http_request',
      target: 'https://api.example.com/health',
      frequencyMinutes: 5,
    },
  ],
  jobs: [
    {
      name: 'Nightly E2E suite',
      tests: ['_supercheck_/playwright/checkout.pw.ts'],
      jobType: 'playwright',
      cronSchedule: '0 2 * * *',
    },
  ],
})

Deployment

Run it on your servers or ours

Isolated by default

Tests run in isolated Kubernetes workloads sandboxed with gVisor. Private and cluster networks are blocked, so a test script cannot reach your infrastructure.

How execution works

Self-host for free

The core is open source under AGPLv3. Run it on your own servers with Docker Compose and K3s, with no license fee and no usage limits.

Self-hosting guide

Or let us run it

Supercheck Cloud is a managed service with monitoring locations in Europe, North America and Asia Pacific. It is coming soon; the waitlist is open.
