One debugging workspace

See the event. Find the cause.

Stop jumping between consoles, inspectors, and scattered logs. PulseRN correlates the signals around a bug so you can understand what happened—and what happened just before it.

PulseRN desktop debugger showing events in a unified chronological timeline

Follow interactions, navigation, requests, state, and errors in sequence.

A clearer debugging loop

The context you need, together.

01

Unified timeline

Trace logs, network calls, navigation, Redux actions, performance, storage, and errors—with saved views, bookmarks, and correlations.

Explore the timeline

02

Native JavaScript debugger

Debug Hermes with original TypeScript sources, breakpoints, stepping, scopes, evaluation, React components, and render profiling.

03

Built for local development

Use loopback or pair a physical device securely. Capture stays bounded, configurable, and under your control.

Connect a device

04

Evidence-backed diagnostics

Turn errors, failed requests, state changes, navigation, performance, and transport health into deterministic findings.

Explore diagnostics

05

AI-ready debugging

Connect Codex, Claude, Cursor, or another MCP client with read-only, debugger, or full local access.

Set up MCP

06

Portable sessions

Retain large histories locally, annotate important events, and move checksummed sessions between computers.

Work with archives

From install to insight

Connect in minutes.

  1. Install PulseRNChoose the desktop build for your platform.
  2. Add the SDKInstall one package and initialize it in development.
  3. Run your app

    PulseRN discovers the session and starts building the timeline.

Follow the quickstart 

// Install the SDK
$ pnpm add @pulse-rn/sdk

import { PulseRN } from '@pulse-rn/sdk';

PulseRN.connect({
  appName: 'My React Native App',
  enableConsole: true,
});

Expo and bare React Native

Small integration. Rich visibility.

Start with the signals you need and expand as you debug. The SDK supports console capture, network inspection, navigation, Redux, performance measurements, storage, errors, connection health, category sampling, and persistent development identity.

  • Safe, bounded serialization
  • Configurable redaction
  • Original console behavior preserved
  • Automatic reconnection
  • Typed sampling and dropped-event diagnostics
