Supercheck

For developers

Tests and monitors that live next to your code

Define Playwright tests, k6 scripts, monitors and schedules in TypeScript. Review them in pull requests, then deploy them from your terminal or CI with the Supercheck CLI.

What Supercheck fixes

Monitors edited by hand drift

A change made in a web form leaves no review trail. With supercheck.config.ts, monitor and job changes go through a pull request, and supercheck diff shows what a deploy will change.

Green in CI, broken in production

Run the same Playwright tests from CI, then schedule them as jobs or attach them to synthetic monitors that keep checking production.

Flaky selectors eat your afternoon

AI Fix reads a failed run and proposes a change to the script. You review it side by side with the original and decide whether to apply it.

Start from the project you already have

Pull exports an existing project into a config file and test scripts. From then on, diff and deploy keep Supercheck in step with your repository.

  • Monitors, jobs, alert channels, variables, tags and status pages in one file
  • Test scripts written under _supercheck_/
  • Changed files are backed up before pull overwrites them
Monitoring-as-code commands
terminal
# Export what already exists in the project
supercheck pull

# See exactly what a deploy would change
supercheck diff

# Apply the configuration
supercheck deploy

# Write a GitHub Actions workflow for pull requests and main
supercheck ci init --github

Fix a failing test without starting over

Write tests in the Playground with templates and autocomplete. When one fails, AI Fix suggests a change that you can accept or reject.

  • Browser, API, database and custom Playwright tests
  • AI Create drafts a test from a description
  • Variables and secrets available inside every script

Give your coding agent the context

Install the Supercheck skill for your coding agent, and connect AI tools to the read-only MCP server so they can look at tests, runs, monitors and incidents.

  • supercheck agent install for Claude, Cursor, Codex and OpenCode
  • MCP clients sign in with your Supercheck account
  • The MCP server is read-only and off by default when self-hosting
Connect an MCP client
terminal
# Install the Supercheck skill for your coding agent
supercheck agent install --target claude

# Connect Claude Code to the read-only MCP server
claude mcp add --transport http supercheck \
