Sentry vs TrackJS: What are the differences?

Developers describe Sentry as "Cut time to resolution for app errors from five hours to five minutes". Sentry is an open-source platform for workflow productivity, aggregating errors from across the stack in real time. 500K developers use Sentry to get the code-level context they need to resolve issues at every stage of the app lifecycle. On the other hand, TrackJS is detailed as "JavaScript Error Monitoring for Modern Web Applications". Production error monitoring and reporting for web applications. TrackJS provides deep insights into real user errors. See the user, network, and application events that tell the story of an error so you can actually fix them.

Sentry and TrackJS can be primarily classified as "Exception Monitoring" tools.

Some of the features offered by Sentry are:

• Real-Time Updates: For the first time, developers can fix code-level issues anywhere in the stack well before users even encounter an error.
• Complete Context: Spend more time where it matters, rather than investing in low-impact issues.
• Integrate Everywhere: Drop-in integration for every major platform, framework, and language -- JavaScript, Python, PHP, Ruby, Node, Java, .NET, mobile.

On the other hand, TrackJS provides the following key features:

• Telemetry Timeline: More than just an error. The Telemetry Timeline shows the user, network, and console events that preceded an error, like an airplane's BlackBox for your webapp.
• Realtime Dashboard: Compare the hits and errors for your webapp over time. See if a recent change is causing failures, and where to prioritize debugging.
• Intelligence Alerting: Get notified when issues important to you are happening, right to your email or chat room.

"Consolidates similar errors and makes resolution easy" is the primary reason why developers consider Sentry over the competitors, whereas "Great error reporting" was stated as the key factor in picking TrackJS.

Sentry is an open source tool with 21.2K GitHub stars and 2.42K GitHub forks. Here's a link to Sentry's open source repository on GitHub.
