15 Other Options Considered

TrackJS JavaScript Error Logging

Top Pro

Telemetry timeline

Understanding the console, network, and user events that led up to an error makes it possible to recreate it in development. See More

Top Con

Multiple errors from the same user can bloat your metrics

No "distinct" error count. If a loop ends up inflating a single user's error count, all reports are affected. Dashboard skewed by weird outliers. Recently (as of February 2018) sorting by "users impacted" was introduced to reduce this problem. See More

Greg Lockwood's Experience

Loved TrackJS. Has clear stack traces to make finding problems much easier. Responsive support, they responded quickly to bugs I submitted. Plus, having met Todd, I believe in his vision and dedication to the cause. See More

Specs

Hosting options:Cloud

Top Pro

Realtime notifications

See when new errors are happening in Slack or Hipchat rooms. See More

Top Con

No deployments using a REST API call

Eric Richardson's Experience

We are using TrackJS to catch errors in both a traditional jQuery/JS application and a couple of AngularJS applications. We have been able to catch a bunch of errors that we may not have otherwise known about, and have been able to debug them easily using the information given in the details. Would absolutely recommend their service to anyone needing to know what's happening client side with their application! See More

Top Pro

Wraps console.log for errors

All messages sent into console are included with error messages for additional context and logging. See More

Jeff Fleishhacker's Experience

TrackJS is an invaluable part of the ReadWorks.org web application's production monitoring and troubleshooting workflow. TrackJS helps us monitor and troubleshoot our web application. The detailed breakdown of each issue helps us determine where our application needs work, what types of users are experiencing the problem, and what actions the user has taken leading up to the breakage. The overview helps us see trends and quickly make decisions about where to focus our fixes. The ability to add custom metadata helps us classify and reference back to our internal data each of the issues TrackJS catches. See More

Top Pro

Error trends

Reports show what are the important errors to focus on fixing. See More

Mirko's Experience

TrackJS has helped us track down lots of hard-to-find bugs and monitor the overall client-side error rate in a very effective manner. I highly recommend anyone developing web apps to try it out! See More

Top Pro

Ability to track an error down to a specific customer (if necessary)

TrackJS supports custom user IDs, which can be random strings that we, the customer can assign to a certain user. This helps a lot when handling a support request or a bug report from customers. See More

Kevin Borders's Experience

TrackJS does a great job of grouping errors together across different builds without over-aggregating different errors. The support for source maps and including console.log statements makes it easy to isolate the source of exceptions. See More

Top Pro

Daily summary email

You can see how your site is doing every day with a summary of all the interesting activity and errors that should be checked into. See More

Levi Tomes's Experience

We use TrackJS for a few products that run in different environments, and in some cases on unexpected hardware/software configurations. TrackJS helps us capture application state on the client at exception time that was nontrivial to collect and correlate to our backend logs in our other services. It also provides an interface that allows developers as well as non-developers to compose rules/error groups in a way that technical support and qa can leverage trackJS data without developer intervention in many cases. See More

Top Pro

Engineer Support

You will always get an engineer who can understand and answer your question right away whenever you need help. See More

SuccessfulMehen's Experience

Great product, great support. See More

Top Pro

Highly customizable with custom JS code on the page

Hooks in the code that let you customize just about anything, you can get the error object before it's sent to the server and do whatever you like with it. See More

Thomas Christie's Experience

I used TrackJS for my PhD thesis work. I created game and recruited people to play the game via Amazon Mechanical Turk. Using TrackJS code in the game Javascript allowed me to track user progress through the game and be aware of bugs (with stack traces!) - which was critical for me, as I didn't have the resources to test my game for every browser and version. I plan to use TrackJS for any future client-side javascript code I deploy. It's become indispensable for me. See More

Top Pro

Inline sourcecode snippets

Error messages and stacktraces are shown with snippets of the raw source at the location. This gives a ton of context to quickly find the error. See More

HonorableHehu's Experience

I've been VERY satisfied with TrackJS. I have used the service with various SPAs for about three years. I think two of the top features for me are the telemetry timeline and analytics dashboard. It's also very ease to see what's happening from the recents view. I also use the email summaries and realtime notifications. I don't have any cons to list. See More

Top Pro

Powerful ignore rules and grouping rules

To ignore spurious errors. See More

Farhan Ahmad's Experience

We are using TrackJS for keeping an eye on an AngularJS app. The realtime and daily notification notifications/emails give us peace of mind that the app is doing well. For errors, the stack traces and debugging info has been helpful in tracking down bugs. See More

SuccinctSabazios's Experience

InsightOps (previously Logentries)

TG's Experience

This doesn't really belong in this category. it aggregates the logs from the clients, but doesn't do a great job surfacing errors or showing which ones are impactful. This is primarily a server log aggregator solution and does not really help client-side problems. See More
