Open-source testing, monitoring, and AI SRE — as code.
Supercheck brings Playwright test automation, k6 performance testing, uptime and synthetic monitoring, incident investigation, and public status communication into one platform. Use the web application, manage resources from the CLI, and record browser tests with the Supercheck Recorder.
- Test automation: browser, API, database, custom, and k6 performance tests, with AI-assisted creation and failure analysis.
- Monitoring: HTTP, website and SSL, ping, port, and scheduled synthetic browser checks.
- Investigation: run logs, screenshots, traces, linked artifacts, and read-only AI SRE investigation over Supercheck evidence and configured connectors.
- Communication: alerts through email, Slack, Discord, Telegram, Microsoft Teams, and webhooks, plus public status pages and subscriber notifications.
- Governance: organizations, projects, six RBAC roles, API keys, audit trails, requirements traceability, and coverage snapshots.
- Secure execution: isolated execution environments, network restrictions, and resource limits for Playwright and k6 workloads.
Supercheck combines capabilities that are commonly split across test automation, synthetic monitoring, load testing, status communication, and incident-investigation products. The comparison below describes each product's primary, natively documented scope; integrations or adjacent products may extend it.

* Comparison snapshot: October 2026. Product capabilities may change. "Partial" means available through a separate product or plan, or with limited scope. The pricing page compares costs for Checkly, Datadog, Better Stack and BrowserStack.
Follow the self-hosting guide to install Supercheck on a Linux server and configure HTTPS, optional integrations, backups, and worker scaling.
The CLI requires Node.js 20 or later.
npm install -g @supercheck/cli
supercheck initCreate a token under Organization → CLI Tokens, then authenticate:
supercheck login --token sck_live_...
supercheck pull
supercheck diff
supercheck deployManual AI SRE triage and investigations are enabled by default with a configured AI provider. Automatic AI work and live connector access remain opt-in. On-call engineers can use the incident number shown by incident list or its UUID:
supercheck incident list
supercheck sre triage <incident-number-or-uuid>
supercheck sre investigate <incident-number-or-uuid> --live-connectors
supercheck sre ask "Summarize the strongest evidence" --incident <incident-number-or-uuid>See the CLI guide and command reference for resource management, local execution, and CI/CD usage.
Record browser interactions as Playwright code and send them to the Supercheck Playground:

The application stores platform data in PostgreSQL, schedules work through Redis and BullMQ, and keeps execution artifacts in S3-compatible storage (RustFS in the bundled stack). Workers consume execution queues and run Playwright or k6 workloads in isolated execution environments. Increase WORKER_REPLICAS and set RUNNING_CAPACITY to the same value to increase execution capacity.
