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

Test with Playwright and k6. Monitor your sites and APIs, keep users informed with status pages, and investigate incidents with AI that shows its evidence. Self-host today, or join the Supercheck Cloud waitlist.

Platform

One place for the work between deploy and incident

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

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
Recorder extension for Chrome and Edge
AI test generation and failure fixes
Requirements with coverage tracking

Automate docs

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

Communicate

Tell your team first, then tell your users.

Alerts 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
Project dashboard for runs, jobs and uptime

Communicate docs

Public status page showing all systems operational

Investigate

Find the cause of an incident with evidence, not guesses.

Incidents linked to the alerts and runs that raised them
AI SRE investigations that cite their evidence
Read-only connectors for GitHub, Kubernetes, Prometheus, Grafana, Sentry and Datadog
Private Agent for systems inside your network

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.
