Core Capabilities

Everything you need to resolve mobile crashes faster.

TraceX pairs real-time crash capture with AI diagnostics to identify why failures happen and generate verified fixes.

Intelligent Diagnostics92% First-Shot Precision

Context-Aware Root Cause Analysis

TraceX goes beyond raw stack traces. It correlates execution stacks, device hardware state, and user interaction breadcrumbs to explain the root cause clearly.

Correlates async network responses with UI state transitions
Captures device memory, battery level, and OS platform variations
Pinpoints the exact logical flaw in seconds
Automated DiagnosisNull Pointer Guard Violation
The checkout controller attempted to dereference `authState.user!` before the authentication token exchange resolved. Added safe navigation and an early guard clause.
Developer Quickstart

Install in 2 minutes. Pure Dart VM.

Lightweight integration engineered directly for Flutter. Zero native NDK bridging required, with instant crash traps and persistent offline buffering.

Live Simulator

Trigger a simulated exception to preview telemetry capture:

lib/main.dart
1import 'package:flutter/material.dart';
2import 'package:tracex_flutter/tracex_flutter.dart';
3
4void main() async {
5  WidgetsFlutterBinding.ensureInitialized();
6
7  // Initialize TraceX SDK before runApp
8  await TraceX.initialize(
9    apiKey: "tracex_live_pub_98a72bc4",
10    offlineBuffer: true,
11    captureBreadcrumbs: true,
12  );
13
14  runApp(const MyApp());
15}

Eliminate runtime crashes before they impact users.

Deploy the TraceX Flutter SDK in minutes to get automated root cause analysis, real-time crash dispatch, and verified code fixes.
