Supercheck

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.

\* 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.

Get started

Self-host Supercheck

Follow the self-hosting guide to install Supercheck on a Linux server and configure HTTPS, optional integrations, backups, and worker scaling.

Install the CLI

The CLI requires Node.js 20 or later.

npm install -g @supercheck/cli
supercheck init

Create a token under Organization Admin > CLI Tokens, then authenticate:

supercheck login --token sck_live_...
supercheck pull
supercheck diff
supercheck deploy

Manual 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.

Install the recorder

Record browser interactions and save Playwright tests directly to Supercheck:

• Chrome Web Store
• Microsoft Edge Add-ons
• Source and build instructions
• Recorder documentation

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.
