Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • compare_reportsCompare two crispy reports

    Diffs a baseline report against a new one and lists render regressions and improvements per component.

  • inspect_componentInspect one component in a report

    Returns the full per-phase stats for one component (render causes and changed prop keys), which tells you whether to reach for React.memo, useCallback/useMemo or state colocation.

  • profile_urlProfile React renders of a URL

    Opens a URL in headless Chromium, optionally runs interaction steps, and reports which React components rendered, how often, why (props/state/context/parent) and which renders were wasted. Render counts are deterministic: use this before and after a change to verify a performance fix.

  • run_scenariosRun crispy.config.json scenarios

    Runs the scenarios defined in a crispy.config.json (budgets included) and returns a summary. Write the report to a file to compare it later with compare_reports.

  • scan_appFind and profile interactions automatically

    Zero-config start: opens the app, finds safe interactions on a few routes (buttons, tabs, text inputs; never delete/pay/sign-out/submit), profiles each one and returns the top root causes of avoidable renders with fixes, plus the scenarios as crispy.config.json scenarios so they can be saved and guarded with test_render_snapshots.

  • test_render_snapshotsCheck render counts against the committed snapshot

    Runs the crispy.config.json scenarios and compares render counts with the committed snapshot (crispy.snap.json), like snapshot tests for re-renders. Regressions include the unstable prop, where the component is rendered and a suggested fix. Read-only by default: it never edits an existing snapshot. With no snapshot yet, update=true records the first one (it only stores the current counts). To accept changed counts later, the USER must approve; then pass update=true together with confirm="accept-render-changes".
