The record

Product: Supercheck describes itself as an open-source platform for testing, monitoring, and AI-assisted site reliability engineering.
Testing: It supports browser tests with Playwright, API tests, database tests, custom Node.js tests, and performance tests with k6.
AI assistance: AI features include generating tests from plain-English descriptions and suggesting fixes for failing tests.
Monitoring: Monitor types include HTTP, website, ping, port, and synthetic monitors, with checks available from multiple geographic regions.
Incident investigation: Its AI SRE gathers read-only evidence, explains likely causes with citations, and recommends fixes and recovery checks; it does not apply fixes.
Integrations: Read-only connectors include Prometheus, Grafana, AWS CloudWatch, Datadog, Loki, Elasticsearch/OpenSearch, Grafana Tempo, Kubernetes, Sentry, GitHub, GitLab, PagerDuty, and Opsgenie.
Notifications: Alert channels include Slack, email, Discord, Telegram, Microsoft Teams, and webhooks.
CI/CD: The CLI supports CI/CD job triggers and monitoring-as-code, and the docs give GitHub Actions and GitLab CI examples.
Status pages: It supports public status pages with incident updates and subscriber notifications.
Security: The self-hosting documentation says user-authored tests run in ephemeral K3s jobs isolated with gVisor.
Private connectivity: The optional Private Agent connects outbound over HTTPS and is designed to query internal services without opening inbound firewall ports.
Execution limits: The tests documentation states that Playwright executions have a five-minute maximum runtime and k6 executions have a 60-minute maximum runtime.
Platform requirements: The documented single-server deployment requires Linux; macOS, Windows, and WSL2 are not supported for the execution sandbox.
Browser extension: Supercheck provides a Chrome recorder extension that captures browser interactions for Playwright tests.
