Crashlytics vs Logstash: What are the differences?

What is Crashlytics? The world's most powerful, yet lightest weight crash reporting solution. Free for everybody. Instead of just showing you the stack trace, Crashlytics performs deep analysis of each and every thread. We de-prioritize lines that don't matter while highlighting the interesting ones. This makes reading stack traces easier, faster, and far more useful! Crashlytics' intelligent grouping can take 50,000 crashes, distill them down to 20 unique issues, and then tell you which 3 are the most important to fix.

What is Logstash? Collect, Parse, & Enrich Data. Logstash is a tool for managing events and logs. You can use it to collect logs, parse them, and store them for later use (like, for searching). If you store them in Elasticsearch, you can view and analyze them with Kibana.

Crashlytics and Logstash are primarily classified as "Mobile Error Monitoring" and "Log Management" tools respectively.

Some of the features offered by Crashlytics are:

• Instead of just showing you the stack trace, Crashlytics performs deep analysis of each and every thread. We de-prioritize lines that don't matter while highlighting the interesting ones. This makes reading stack traces easier, faster, and far more useful!
• Crashlytics' intelligent grouping can take 50,000 crashes, distill them down to 20 unique issues, and then tell you which 3 are the most important to fix.
• Now you'll get precise information on the performance of the devices that your apps run on. We'll let you know if the crash only happens on a specific model or generation of a device. We'll even tell you other information, like whether your app only crashes in landscape mode, or whether the proximity sensor is always on.

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

• Centralize data processing of all types
• Normalize varying schema and formats
• Quickly extend to custom log formats

"Crash tracking" is the primary reason why developers consider Crashlytics over the competitors, whereas "Free" was stated as the key factor in picking Logstash.

Logstash is an open source tool with 10.3K GitHub stars and 2.76K GitHub forks. Here's a link to Logstash's open source repository on GitHub.

According to the StackShare community, Logstash has a broader approval, being mentioned in 551 company stacks & 270 developers stacks; compared to Crashlytics, which is listed in 350 company stacks and 68 developer stacks.
