TrackJS JavaScript Error Logging

Add Video or Image

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

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

Specs

Hosting options:Cloud

Languages:JavaScript

Price:$49/month

Top Pro

Error trends

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

Top Con

No deployments using a REST API call

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

Wraps console.log for errors

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

Realtime notifications

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

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

SuccinctSabazios's Experience

We have been using TrackJS at Blake for a few years now. It gives us extra confidence in deploying new code. Bugs will always find a way to creep into production, at least with TrackJS we can catch them before customers ever see them. 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

SuccessfulMehen's Experience

Great product, great support. 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

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

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

ThoroughMormo's Experience

Awesome... Showed us things we didn't even know to look for! Must have tool in any Dev's monitoring toolset. See More

Top Pro

Find bug in product easily

TrackJs is very useful to catch console 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

Top Pro

Analytics dashboard

A snapshot of how you are doing, comparing page view volume to error volume. See More

Eva Szadeczky-Kardoss's Experience

What I loved with this one: super easy setup, flexible notification settings and the very useful console.log feature. I also considered Google solutions and trakerr.io but neither did what I needed. TrackJS does. See More

Sam Schneider's Experience

We have been able to quickly find out checkout funnel affecting JS errors that were sometimes missed during the QA process. See More

Top Pro

Client specs

Some general information like browser, operating system and viewport used by the client may help to determine source of trouble more precisely. See More

IndependentBarraiya's Experience

Top Pro

Source maps

Specs

Hosting options:Cloud or Self-hosted

Top Con

JavaScript client library bloats bundle

JS library is literally HUGE! Half of my main bundle is Sentry. They promise to fix this on v7.0.0, but they don't give any estimates as to when it will be done. See More

Top Pro

Tracebacks (stack traces)

Top Con

Setup instructions are poorly explained

The client keys page of the setup section has keys that have the public and private keys in them. This isn't explained on the page, so when integrating Sentry with another service, it's easy to mistakenly copy the private key when you wanted the public key. See More

Top Pro

Pinpointing of errors (in your JS source file)

With Sentry, you won't have to get those meaningless and hard to figure out error messages with your minified JS files. All you need to do is provide Sentry with a source map and it'll decompress your JS file and pin point to which line is causing the error. See More

Top Con

Some old issues still not fixed

There are still some old issues, specifically speaking, with the Ruby Client that haven't been fixed yet. See More

Top Pro

Open source

Sentry's source code is publicly available via their Github repository See More

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

Specs

Hosting options:Cloud hosted

Supported languages:Android / GoLang / JavaScript/HTML5 / iOS / Java / .NET / .NET Serilog / PHP Logging / Python

Platforms:Windows, Linux, Mac

Supported input methods:Token-based / Plain TCP/UDP / HTTP PUT

Rollbar
