When a new release goes out, you want to know if players are experiencing issues due to that release. You will want to know where the error occurred and if there are commonalities to the players who are experiencing the issue. ## Tools for Error Tracking and Application Performance Monitoring This is where error tracking tools come into play. There are many to choose from and they have different features and price points. Here are some great options for error tracking tools, in a table for easier comparison. Note that each of the products and services may offer more than just error tracking in its feature set. | Service | Can it be self-hosted? | Free Tier | | ----------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------- | | [Rollbar](https://rollbar.com/?ref=modernlearner.org) | No | [Yes, 5,000 occurrences and 1,000 sessions per month, maximum data retention of 30 days](https://rollbar.com/pricing?ref=modernlearner.org) | | [Datadog](https://www.datadoghq.com/?ref=modernlearner.org) | No | [No free tier, only a 14-day trial is available](https://www.datadoghq.com/pricing/?product=error-tracking&ref=modernlearner.org#products) | | [BugSnag](https://www.bugsnag.com/?ref=modernlearner.org) | No | [Yes, 7500 events and 1M spans per month, 1 user only](https://www.bugsnag.com/pricing/?ref=modernlearner.org) | | [Raygun](https://raygun.com/?ref=modernlearner.org) | No | [14-day trial only](https://raygun.com/pricing?ref=modernlearner.org) | | [PostHog](https://posthog.com/error-tracking?ref=modernlearner.org) | Yes, [instructions for self-hosting open source PostHog](https://posthog.com/docs/self-host?ref=modernlearner.org) | [Yes, 100,000 exceptions per month](https://posthog.com/pricing?ref=modernlearner.org) | | [GlitchTip](https://glitchtip.com/?ref=modernlearner.org) | Yes, [installation instructions for open source GlitchTip](https://glitchtip.com/documentation/install?ref=modernlearner.org) | [Up to 1000 events per month, unlimited projects, unlimited team members](https://glitchtip.com/pricing?ref=modernlearner.org) | | [Highlight.io, now part of LaunchDarkly](https://www.highlight.io/?ref=modernlearner.org) | Yes, [instructions for self-hosting for up to 50k errors per month](https://www.highlight.io/docs/general/company/open-source/hosting/self-host-hobby?ref=modernlearner.org) | Yes, 5k errors per month | | [BugSink](https://www.bugsink.com/?ref=modernlearner.org) | Yes | Yes, 5k errors per month | **However, not all error tracking tools have official support for some programming languages and frameworks.** *Not all of them have clear documentation, tutorials and guides.* It's important to evaluate error tracking tools based on whether they support the programming languages your team is using, the user interface to view the errors, whether it supports SAML and Single Sign On, and whether the documentation is helpful. For example, [PostHog has an official Android SDK but does not have an SDK for iOS although that gap can be filled by capturing errors and exceptions and manually sending them via HTTPS](https://posthog.com/docs/error-tracking/installation/manual?ref=modernlearner.org). Self-hosted open source versions of the error tracking service may also differ in the feature set and offer fewer features than the cloud-hosted version. ## Implementing Error Tracking Typically, the SDKs for each error tracking service will provide a way to capture all errors and exceptions and send them to the service, the only requirement being that you create an account and supply an API key. Other parameters such as the version release number and user information can be included when sending data about the error that occurred. The following is a reference with links to packages for each error tracking tool along with code samples to show how to add them to your project.

MIDDLEWARE = ( "bugsnag.django.middleware.BugsnagMiddleware", ) ``` ### Implementing Error Tracking in JavaScript for Browser-Based Games #### [Rollbar for JavaScript and TypeScript](https://github.com/rollbar/rollbar.js/tree/master/examples?ref=modernlearner.org) Rollbar can be added to [React](https://docs.rollbar.com/docs/react-ts?ref=modernlearner.org), [Angular](https://docs.rollbar.com/docs/angular?ref=modernlearner.org), and [Vue](https://docs.rollbar.com/docs/vue-js?ref=modernlearner.org): ```javascript import Rollbar from 'rollbar'; const rollbar = new Rollbar({ accessToken: 'ROLLBAR_ACCESS_TOKEN', environment: 'production', }); ``` #### [BugSnag for JavaScript](https://docs.bugsnag.com/platforms/javascript/?ref=modernlearner.org) ```javascript import Bugsnag from '@bugsnag/js'; Bugsnag.start({ apiKey: 'BUGSNAG_API_KEY', onError: (event) => { event.setUser('user-id', 'user-email@localhost', 'User Name'); } ); ``` #### [Datadog for JavaScript](https://docs.datadoghq.com/error%5Ftracking/frontend/browser/?tab=npm&ref=modernlearner.org) ```javascript import { datadogRum } from '@datadog/browser-rum'; datadogRum.init({ applicationId: 'APP_ID', clientToken: 'CLIENT_TOKEN', service: 'SERVICE_NAME', env: 'ENVIRONMENT_NAME', version: '1.0.0', trackUserInteractions: true, trackResources: true }); ``` ## Migrating From Sentry to BugSink or GlitchTip The advantage of BugSink and GlitchTip are that they are open source and can be self-hosted. In addition, both error tracking services are compatible with Sentry SDKs. That means you can use the Sentry SDK with any language that they support, set the `dsn` URL endpoint to BugSink or GlitchTip and start tracking. If you choose to use the cloud version of BugSink or GlitchTip, here's how their error tracking plans compare to Sentry (as of February 2026), with the number of error events the plan can track per month: | Service | Plan | Monthly Price | \# of Errors Included | | --------- | ---------- | ------------- | --------------------- | | Sentry | Developer | Free | 5k | | BugSink | Developer | Free | 5k | | GlitchTip | Developer | Free | 1k | | Sentry | Team | $26 | 50k | | BugSink | Team | $18 (€15) | 50k | | GlitchTip | Small | $15 | 100k | | Sentry | Business | $80 | 50k | | GlitchTip | Medium | $50 | 500k | | GlitchTip | Large | $250 | 3 million | | BugSink | Enterprise | $600+ (€500+) | Millions of events | This is the example code in Python that will send error traces to BugSink by configuring the Sentry SDK: ```python import sentry_sdk import time sentry_sdk.init( dsn="http://your_key@localhost:8001/1", traces_sample_rate=1.0 ) print("Causing an error") 1 / 0 ``` This is JavaScript/TypeScript/HTML example code that will send errors to GlitchTip, again by configuring the Sentry SDK to use a different `dsn` URL endpoint value: ```html
