13 Most Useful CI/CD Tools for DevOps in 2024

cicd tools

Continuous integration (CI) and continuous delivery (CD) are the unsung heroes that operate behind the scenes of every successful company. 

CI is a software development practice where engineers merge their code into a central repository multiple times a day. After a pull request is open and after a merge is done, automated builds and tests are triggered automatically to ensure the functionality of the code. This approach promotes a collaborative environment and also helps in identifying issues early on, minimizing the risk of having issues propagated through different environments.

CD is the natural extension of CI, focusing on automating the deployment of the software updates that are done to designated environments after the CI builds and tests finish successfully. By minimizing manual interventions and automating the release process, CD helps organizations achieve quicker feedback loops and ensures the transition between environments and releases goes smoothly.

What are CI/CD tools?

CI/CD tools are specialized software applications that are designed to facilitate the practices of continuous integration and continuous delivery throughout the software development lifecycle (SDLC). These tools are responsible for managing the tasks associated with automated code integration, building, testing, packaging the code, and deploying the infrastructure/application code to various environments. By using CI/CD tools, development teams can easily streamline their workflows, detect and resolve issues quickly, and ensure the reliability of their software.

How to choose the right CI/CD tool?

There is no right or wrong way to choose a CI/CD tool. Each tool has different strengths. Just as restaurants may excel at a few popular specialty dishes, no CI/CD tool can build, test, and deploy absolutely everything to the same level of excellence.

Spacelift specializes in infrastructure management, and it’s one of the best choices available in this area. However, if your company develops a Java application and does maven or gradle builds, Spacelift will not be super helpful.

When choosing a CI/CD tool, you should consider the following: 

  • what are you going to deploy
  • how much are you willing to spend
  • how much uptime you need
  • how it integrates with your existing tech stack
  • how customizable the tool needs to be
  • whether auto-scaling is important
  • how easy the tool is to learn
  • what the UI/UX is like

You need to consider many aspects, and evaluating multiple tools at the early stages makes a lot of sense.

Key Points

In this post, we’ve reviewed the best CI/CD tools on the market and some best practices when it comes to choosing the right CI/CD tool for your needs. There are many tools in the DevOps ecosystem, and the ecosystem is constantly growing and improving, so picking the best CI/CD tool can be hard if you don’t evaluate it specifically for your use case.
