Prometheus vs New Relic: Which One for Startups
Prometheus is used by over 80% of companies adopting Kubernetes. New Relic, on the other hand, serves more than 17,000 customers around the globe. These numbers tell a story that can’t be ignored. But honestly, just because something’s popular doesn’t mean it’s the best fit for your startup.
| Tool | GitHub Stars | Forks | Open Issues | License | Last Release Date | Pricing |
|---|---|---|---|---|---|---|
| Prometheus | 47,000+ | 7,000+ | 60+ | Apache 2.0 | April 2026 | Free |
| New Relic | 15,000+ | 2,000+ | 150+ | Commercial | May 2026 | Starts at $99/month |
Tool A: Prometheus
Prometheus is an open-source monitoring and alerting toolkit, initially designed for reliability and scalability for metrics-based systems. It pulls data from configured endpoints at specified intervals and stores it in a time-series database. The power of Prometheus lies in its ability to provide not just metrics, but also multi-dimensional data querying capability through its powerful query language, PromQL. This makes analyzing and drawing insights from your data incredibly efficient.
# Sample Prometheus query to get CPU usage of nodes
sum(rate(node_cpu_seconds_total{mode="user"}[5m])) by (instance)
What’s Good
- It’s free, which is crucial for startups on a budget.
- Strong community support and excellent documentation.
- PromQL offers a flexible query language, making complex queries straightforward.
What Sucks
- Steep learning curve. If you’re not familiar with metrics or time series, you might be in for a rough ride.
- No built-in support for log management; you’ll need to adopt other solutions like Grafana to visualize your data.
- Alerting can become convoluted if your infrastructure is complex.
Tool B: New Relic
New Relic is a commercial software analytics and performance monitoring tool that aggregates data from your application, infrastructure, and user experiences. It automatically detects application performance issues and provides a slew of insights, visualizations, and performance monitoring features like dashboards and real-time alerting. While it’s more straightforward than Prometheus, that ease of use comes with associated costs.
# Example REST call to New Relic's API to get app performance data
curl -X GET 'https://api.newrelic.com/v2/applications.json' \
-H 'X-api-key: YOUR_API_KEY' \
-H 'Accept: application/json'
What’s Good
- User-friendly interface and seamless onboarding process for new users.
- Offers full-stack monitoring, not just limited to metrics.
- Excellent customer support and many built-in integrations.
What Sucks
- High pricing can quickly become unaffordable, especially for small teams.
- Lock-in issues; moving away from New Relic generally means a lot of migration pain.
- While it offers a lot of features, the depth can be overwhelming for smaller teams just getting started.
Head-to-Head
1. Cost
Prometheus wins this one. Being free is a major advantage for bootstrapped startups. New Relic starts at $99/month, which adds up quickly. If you’re watching every dollar, Prometheus is the clear choice here.
2. Ease of Use
New Relic takes this round. The learning curve for Prometheus can be steep if you’re new to metrics. New Relic’s interface is clean and intuitive, providing immediate insights with minimal configuration.
3. Flexibility
Prometheus wins hands-down. Its powerful query language allows for complex data manipulations that New Relic just can’t match. If you need to analyze your metrics in-depth, Prometheus is the way to go.
4. Community Support
Prometheus has a larger open-source community. You can find countless resources, forums, and tools that plug into Prometheus. New Relic has commercial support but lacks the active community engagement that thrives in open-source projects.
The Money Question: Pricing Comparison
| Tool | Base Cost | Hidden Costs | Free Tier |
|---|---|---|---|
| Prometheus | $0 | Cost of additional infrastructure | Yes |
| New Relic | $99/month | Costs increase with more data ingestion and features | No |
My Take
If you’re a small startup looking to save every possible dollar, pick Prometheus. It gives you excellent power at no cost. If you’re a team of non-techies who just want to visualize some metrics without diving into the depths of code, New Relic is the better option. But be prepared to open your wallet.
- Technical Founder: Pick Prometheus for customizable metrics and a zero-dollar budget.
- Product Manager: Choose New Relic for ease of visualization and a straightforward onboarding experience.
- DevOps Engineer: Go with Prometheus for unparalleled flexibility in querying and integration capabilities.
FAQ
1. Can I use both tools together?
Yes, some companies use Prometheus for monitoring and New Relic for APM to leverage strengths from both.
2. What’s better for Kubernetes?
Prometheus is actually built with Kubernetes in mind, making it the optimal choice in that environment.
3. What’s the best way to visualize Prometheus data?
Grafana is a popular solution for visualizing data collected by Prometheus.
4. Is New Relic worth the cost?
It depends on your needs. If you need a comprehensive solution for multiple use cases, it might be worth the investment.
5. How do I migrate from New Relic to Prometheus?
It’s definitely a process. You’ll have to set up Prometheus, export existing data, and reconsider your monitoring strategy altogether.
