Supercheck

What Supercheck is
Supercheck is an open-source platform for software testing, monitoring, and AI-assisted site reliability engineering. It supports Playwright browser tests, API and database tests, custom Node.js tests, and k6 performance tests. Monitors cover HTTP, websites, ping, ports, and synthetic checks from multiple regions. AI can create tests from plain-English descriptions and suggest fixes for failures. Its AI SRE gathers read-only evidence, explains likely causes with citations, and recommends fixes and recovery checks without changing production systems. A Chrome recorder captures interactions and saves Playwright tests. The CLI supports CI/CD triggers and monitoring-as-code, with GitHub Actions and GitLab CI examples. Read-only connectors include Prometheus, Grafana, AWS CloudWatch, Datadog, Loki, Elasticsearch/OpenSearch, Tempo, Kubernetes, Sentry, GitHub, GitLab, PagerDuty, and Opsgenie. Alerts can use Slack, email, Discord, Telegram, Microsoft Teams, or webhooks. Public status pages, audit trails, RBAC roles, isolated workloads, and optional private connectivity are included.
Who it suits
It suits engineering teams that need combined automated tests, monitoring, incident investigation, and status communication. Self-hosting users need Linux and the documented server requirements.
What it does well
- Supports browser, API, database, Node.js, and k6 tests
- AI generates tests and suggests failure fixes
- Read-only incident analysis includes cited evidence
- Offers many observability and alert integrations
- Chrome recorder creates Playwright tests
What to know first
- Playwright runs have a five-minute maximum
- k6 runs have a 60-minute maximum
- Execution sandbox requires Linux
- AI SRE does not apply remediation
Limits
Playwright test runs stop after five minutes, while k6 runs stop after 60 minutes. The documented execution sandbox does not support macOS, Windows, or WSL2 deployment.
Getting started
- Open https://supercheck.io
- Choose a cloud or self-hosted deployment
- For self-hosting, use Docker Compose on Linux
- Use Ubuntu 22.04+ or Debian 12+, Docker Engine with Compose v2.24.4 or newer, and at least 2 vCPU with 4 GB RAM
- Install the Chrome recorder extension if you want to capture browser interactions
- Connect alert channels, observability tools, or CI/CD jobs through the available integrations and CLI
Verdict
Supercheck combines broad test coverage, monitoring, integrations, and read-only AI incident guidance. Its Linux execution requirement and fixed runtime limits matter when planning deployment and test workloads.
