1-Click Live Virtual Hot-Patching

Instantly neutralize orphaned window/document event listeners, polling setInterval timers, and dangling DOM elements directly on live user sessions without requiring an emergency redeploy or page reload.

              > kernel.applyHotPatch('checkout-container', ['resize', 'message']);

              ✓ [HOTPATCH] 4 dangling listeners neutralized. Tab memory stabilized.

Shared Scope Conflict Auditor

Deep inspection of __webpack_share_scopes__.default. Identifies duplicate singletons of React, Lodash, and Vue, calculating wasted megabytes.

Self-Healing Production Runtime Guard (`@federationpulse/guard`)

Zero-leak insurance for your live production host. Drop our featherweight 1.8 KB runtime guard into your root shell. Whenever any micro-frontend unmounts, the guard autonomously sweeps the DOM and window scope, neutralizing dangling listeners, polling timers, and detached trees in-flight before user tabs crash.

npm i @federationpulse/guard <script src="./guard.min.js"> Slack & Webhook Incident Alerts

                // Host Application Shell

                import { initFederationGuard } from '@federationpulse/guard';

                initFederationGuard({

                  autoNeutralizeDangling: true,

                  reportWebhookUrl: 'https://hooks.slack.com/...'

                });

                // ✓ Autonomous in-flight healing active

10-Tool Bi-Directional MCP Server

Connect Claude Desktop, Gemini, or Codex directly to your running micro-frontends. AI coding agents inspect container teardowns, diagnose root causes, and generate automated AbortController patches live.

              $ claude "Audit the checkout container and neutralize dangling resize listeners"

              ✓ MCP tool `apply_hot_patch` executed successfully in 14ms.

Headless CI Quality Gate & SARIF 2.1.0

Prevent memory regressions before merging. The @federationpulse/playwright SDK introduces the custom matcher expect(page).toHaveZeroMFELeaks() and uploads native SARIF alerts to GitHub Security.

                // Playwright CI Test

                await attachFederationPulse(page);

                await page.click('#unmount-checkout');

                expect(page).toHaveZeroMFELeaks();

Frequently Asked Questions

Everything you need to know.

How does FederationPulse intercept memory leaks without degrading performance?

FederationPulse injects a lightweight kernel that wraps native EventTarget, MutationObserver, and Webpack module federation sharing scopes. The kernel runs in the page context with bounded O(1) overhead and zero external dependencies, maintaining 60 FPS even during heavy DOM thrashing.

Is Live Virtual Hot-Patching safe for production tabs?

Yes! Virtual Hot-Patching operates strictly in-memory. It safely invokes removeEventListener on dangling window/document hooks and disposes detached nodes associated with unmounted container scopes. It does not alter your bundle on disk and leaves healthy active listeners untouched.

How does the MCP Server connect to Claude, Gemini, or Codex?

FederationPulse provides a standard Model Context Protocol (MCP) server over stdio. Simply add FederationPulse to your claude_desktop_config.json or agent settings. Your AI agent gains access to 10 live tools to inspect container boundaries, query shared scopes, and apply virtual patches automatically.

How do subscriptions and Lemon Squeezy billing work?

Payments are handled securely via Lemon Squeezy (Merchant of Record). You will instantly receive a license key upon checkout. Enter the license key in the FederationPulse DevTools extension or Playwright CI config to unlock Pro or Enterprise features across your entire organization.
