Sentry Vs New Relic: Best Error Monitoring For Modern Apps?
Modern apps need reliable error monitoring to keep users happy and businesses running smoothly. But with so many tools out there, choosing the right one can be confusing. Two popular choices are Sentry and New Relic. Both offer powerful features, but they work in different ways. Let’s break down what each tool does, where they shine, and which one could be the best fit for your app.
What Is Sentry?
Sentry is an open-source error tracking tool. It helps developers find, fix, and understand errors in real time. Sentry is loved for its simple setup and clear dashboards. It supports many programming languages like JavaScript, Python, Java, and more.
Sentry shows you exactly where errors happen in your code. For example, if a user clicks a button and an error occurs, Sentry records the error, the line of code, and the user’s device details. This helps you fix problems quickly.
What Is New Relic?
New Relic is a full-featured application performance monitoring (APM) tool. It tracks much more than just errors. New Relic gives you deep insights into your app’s speed, server health, and user experience.
While New Relic can track errors, it also monitors things like CPU usage, memory, and database queries. This makes it popular with bigger teams who want a complete picture of their app’s health.
Side-by-side Feature Comparison
Choosing between Sentry and New Relic often comes down to which features matter most for your team. Here’s a quick look at how they compare:
| Feature | Sentry | New Relic |
|---|---|---|
| Error Tracking | Yes (detailed) | Yes |
| Performance Monitoring | Basic | Advanced |
| Supported Languages | 30+ | 10+ |
| User Interface | Simple | Comprehensive |
| Open Source | Yes | No |
Pricing And Plans
Cost is important, especially for startups or small teams. Here’s how Sentry and New Relic compare on price:
| Plan | Sentry | New Relic |
|---|---|---|
| Free Tier | Yes (5K events/mo) | Yes (basic, limited data) |
| Paid Plans | From $29/mo | From $49/mo per user |
A non-obvious insight: Sentry’s pricing is based on error events, while New Relic often charges per user or host. For teams with many errors but few users, Sentry can be cheaper.
Setup And Ease Of Use
Both tools offer fast setup, but their approaches are different.
- Sentry: You add a few lines of code to your app. Within minutes, errors start showing up on your dashboard.
- New Relic: Setup can be more complex. You install agents on your servers or cloud. This gives you deep data, but the process might take longer.
A common mistake: Beginners often forget to set up proper alert rules. Without alerts, you may miss critical errors until users complain.
When To Choose Sentry
- You want fast error detection and fixes.
- Your team is mostly developers.
- You need to support many languages.
- You prefer open-source tools.
When To Choose New Relic
- You need full app performance monitoring.
- Your team includes DevOps or site reliability engineers.
- You want to monitor servers, databases, and cloud services.
- You need advanced reporting and dashboards.
Real-world Example
A small SaaS startup noticed users were seeing blank pages. With Sentry, they found a typo in their JavaScript code within minutes. Later, as the company grew, they switched to New Relic to monitor slow database queries and server usage.
