Supercheck
Supercheck is a free, open-source platform for testing, monitoring, and AI-assisted site reliability engineering.
What Supercheck is
Supercheck is a free, open-source platform for testing, monitoring, and AI-assisted site reliability engineering. It runs through web, API, extension, Linux, and self-hosted deployments. Testing covers Playwright browser checks, API and database checks, custom Node.js tests, and k6 performance tests. Monitors can watch HTTP services, websites, pings, ports, and synthetic checks from several geographic regions. AI can create tests from plain-English descriptions and suggest fixes for failed tests. Its read-only AI SRE gathers scoped evidence, explains likely causes with citations, and recommends fixes and recovery checks without changing production systems. A Chrome recorder captures browser interactions and saves Playwright tests. Supercheck also provides public status pages, CI/CD triggers, monitoring-as-code, and alerts through Slack, email, Discord, Telegram, Microsoft Teams, or webhooks. Read-only integrations include observability, cloud, infrastructure, source-control, and incident tools. Self-hosted execution requires Linux.
Good
- Open-source platform with free pricing
- Supports browser, API, database, and performance tests
- AI generates tests and suggests failure fixes
- Public status pages and multiple alert channels
- Chrome recorder saves Playwright tests
Watch out
- Self-hosted execution requires Linux
- Playwright runs have a five-minute limit
- k6 executions have a 60-minute limit
- AI SRE does not apply remediation
Who it suits
Supercheck suits teams needing open-source testing, monitoring, incident investigation, and CI/CD workflows. It is also suitable for organizations wanting self-hosting, read-only integrations, or browser-based test recording.
Verdict
Supercheck combines broad automated testing, geographic monitoring, incident guidance, and status communication in one open-source platform. Linux requirements and execution time limits should be checked before self-hosting or designing long-running tests.
