Best Open Source Application Monitoring Tools in 2024
Application Performance Monitoring tools track the performance of applications in real-time but also analyze it in context and in time to spot anomalies and performance-related issues. Open Source Application Performance Monitoring tools give a lot of freedom to their users since they can access and customize the tool's source code for project-specific needs. It also allows for self-hosting, which can help in the context of tightening data protection laws. They also often offer a vibrant community of active developers who might provide helpful plugins and tips.
The market is saturated with free and open-source APM tools, but picking the right one for your stack might be tricky. Let's take a look at some of the most reliable and community-approved open-source application performance tools in 2023.

7. Apache Skywalking
Skywalking is built for Java .NET core, PHP, Node.js, Golang, LUA, Rust, and C++ agents and all of these agents are actively maintained.
Freemium APM Tools
Open-source monitoring tools are great for projects with tight budgets, non-profits, or other open-sourced projects. However, many SaaS offers free or reasonably priced bundles for non-profits, education, and other projects. Also, a self-hosted solution can get expensive really quickly, e.g., a hosted ELK stack from Elastic starts at $95/month. Open Source is rarely free, and many SaaS solutions offer better, more reliable, and reasonably priced, Application Performance Monitoring Tools.

In this article, we took a closer look at some of the best open-source Application Performance Monitoring tools available in 2023. The importance of a good APM solution is now indisputable, so all it takes is to pick the right one. When deciding between an Open source and a SaaS solution, there are a few key aspects to consider:
- Continuity, community, and development. Open Source tools heavily rely on their community. If the last commit was pushed a few months ago and the repository has only a few active members, you risk future security and compatibility issues.
- Infrastructure costs. Open Source tools such as the Elastic stack easily ramp up the infrastructure costs, which diminishes your return on investment and has the potential of draining unnecessary funds.
- Integrations with third-party software. Most Open Source tools integrate well with third-party tools for tasks such as infrastructure monitoring or incident management. It's important to make sure that your stacks are fully compatible.
