This article runs through nine different debugging and error monitoring tools that will assist your debugging process. They can be divided into two main categories: those that help during development, and those that help after the product has been shipped.
Development Debugging (IDEs)
During development, the biggest tool to help you with debugging is your IDE. This article discusses several IDEs that can spot errors and bugs as they might crop up. Several solutions include intelligent debugging utilities that go above and beyond simple error events.
Post-Deployment Debugging (Error Reporters)
These products aggregate bug reports that are submitted either by your testers or end-users. Some products expand on this by integrating with your development environment to allow you to immediate action bug reports. Some even integrate with CI/CD workflow solutions to smooth the bug fixing process.
The error reporting tools provide immediate notifications and integrate Slack, Trello, Github, etc., for better bug notifications and workflow management. In addition, the code snapshots and breadcrumbs features make bug mitigation easier, and the user monitoring provides in-depth information about who is discovering your bugs.
- Error and performance monitoring
- Deployment tracking
- Mitigation tools (e.g., code snapshots)
- CI/CD integration
There is a 30-day free trial available for all of the product’s features. In addition, the product itself is divided into pricing Tiers that determine capacity. For example, the Tier 1 package supports 25k errors and costs $19 per month. At the same time, the Tier 4 package supports up to 1 million errors and costs $299 per month.
These Tiered packages are split between both performance monitoring and error monitoring. This means for both toolsets combined; you’re effectively paying double the price for each Tier. Depending on your capacity needs, this might mean Airbrake is out of your budget, so it's worth considering your exact capacity demands.
The performance monitoring tools can help you diagnose problems in your development projects by allowing you to spot unusual readouts quickly. In addition, a stack tracing tool simulates your development environment, enabling you to debug discovered mistakes and better understand where bugs are occurring in the code.
- Bug tracking
- Fault aggregation workflows
- Performance monitoring
- Log data insights
- Free with premium options
Sentry's primary capabilities are entirely free to use with a limited user capacity. Upgrade to the Team package for $26/month, which increases the error detection algorithms, or the Business package for $80/month, which expands the error insights even more.
A free trial is offered for both the Team and Business editions. If you approach Sentry directly, Enterprise size services are available if you require large-scale considerations such as complete platform error monitoring and cross-project insights.
Glitchtip is an open-source bug reporting application that collects and organizes problem reports into a legible, fixable format. The solution appears to have been developed in response to Sentry's decision to abandon open-source, but it still works with Sentry's open SDK.
You can host the solution locally because it is open-source, but the company also provides hosting choices. In addition, it outperforms other alternatives because it is open-source, which means it has a larger community of users than some other products. Glitchtip is still in its infancy, but it could be the ideal answer for tiny enterprises or low-budget projects that require open-source.
- Bug aggregation
- Performance monitoring
- Integration with Sentry SDK
- Self-hosting options
When self-hosted, Glitchtip is open-source and entirely free. You can also use their hosted platform for free up to 1000 events. They offer services for small, medium, and large businesses in addition to the free hosted alternative.
The Small package is $15 per month and supports up to 100k events. The Medium package costs $50 per month and supports up to 500k events. Finally, the Large package costs $250 per month and supports up to 3 million events.
Raygun aggregates user data to enable accurate crash reporting and bug feedback. The solution splits its primary functions into three different products. This means you can opt into the services you need, which provide a customized product.
The solution includes issue tracking tools as well as debugging mitigation solutions. These features, combined with user data monitoring, make this solution ideal for debugging an existing operational service.
- Error reporting and feedback
- User monitoring
- Crash report diagnostics
- Inbuilt bug fixing information
- Customizable purchase options
The solution is divided into three primary services, which can be tried for free on the website. In addition, your monitoring needs will benefit from the Application Performance Monitoring and Real User Monitoring packages, which start at $8 per month.
Rollbar is an error reporting and fault aggregation solution based on real-time issue identification. You can trace bugs emerge using telemetry data obtained through the various integrations available, which speeds up bug repair.
Automated issue tracking and workflow triggers help you avoid accidentally shipping projects with known but untreated defects. The solution includes a set of notification tools for quick and accurate issue reporting and the ability to categorize bug notifications for easier reading intelligently.
- Error tracking and aggregation
- Bug report management
- Workflow/VCS integration
- Bug notification tools
- Free with premium options
Rollbar is free for up to 25,000 error events and has enough basic capabilities to get you started, especially if you're working in a small development team.
The Essentials plan, which costs $21 per month and covers up to 50,000 error events, is included in the premium plans. The Advanced plan allows for up to 100k error occurrences and a multi-project feed with combined monitoring.
6. Komodo IDE
This solution will provide numerous features to boost your debugging capabilities if you require a new IDE for Python development. The IDE’s In addition, the visual debugger and code inspection capabilities excel at debugging, improving error identification, and preventing problems. In addition, you can avoid defective builds from being distributed thanks to built-in support for VCS like Git and workflow management solutions.
- Visual debugger
- Open-source platform
- CI/CD integrations
- Git integrations
The program may be downloaded and installed on the company's website, but to use it, even the free version, you'll need an ActiveState account.
Because the IDE is free and open-source, it's worth considering if you're on a budget and need a solution. However, keep in mind that it appears to be fading in popularity and support while the product is still supported.
7. Visual Studio
Breakpoints can isolate individual lines of code that are creating problems, and visual debugging tools can be used to diagnose and mitigate concerns. You can also use the debugging tool in step sequences to figure out which line of code is causing the issue.
- Visual debugger
- Debugging tools
- Workflow integrations
Visual Studio is available in various versions, including the Community version, a free, open-source version targeted for individual small-scale developers.
If you operate in a group, you might want to look into the Business options available as part of a $45 per month subscription. For $250 per month, Enterprise services are available for large-scale commercial needs.
8. JS Bin
The utility has collaborative features that allow multiple developers to interact with the same code. Still, unless you pay a premium for a ‘private bin,’ your code is technically exposed to the public. The project is entirely open-source and primarily funds itself through donations and Pro subscriptions.
- Github exporting tools
- Templating features
- Dropbox backup sync
- Collaborative features
JS Bin is entirely free and open source. There is a Pro subscription available for $126 per year or $16 per month. The Pro version removes any capacity limits in place and adds the ability to create private workspaces for secure collaboration.
Selenium's three main functionalities are web automation testing, a development IDE for test scripts, and a central management point. All essential functions are available for free and fully integrated into various CI/CD platforms.
- Scripted web automation testing
- Development IDE
- Multi-environment management
- Browser interaction record-and-playback
- Open-source and free
Finally, Selenium Grid is the management and multi-environment orchestration platform and must be installed on a central server to be installed on. While you don’t need Selenium Grid for your CI/CD pipeline, it will likely be worthwhile for the full integration.
Post-deployment bug fixing is mainly about bug monitoring, reporting, and aggregation. We’ve covered several error reporting solutions in this article, such as Airbrake, Glitchtip, and Rollbar. These error reporting solutions allow your team to identify bugs from testers and end-users and convert the data into actionable tasks.
Overall, if you want to cover your bases, your best choice is to combine a debug-focussed IDE with an error-reporting solution. This will help you catch bugs in the net before deployment and provide you with the best insight into where your bugs exist and how to fix them after your product has been shipped.
