Software development companies have finally started to realize that to thrive in today’s competitive world, a business has to ensure connectivity and collaboration between their development and operations team. So they adopt DevOps practices that ensure a shorter software development life cycle, faster time-to-market, faster resolution of issues, and enhance overall quality of the product.

But for DevOps to deliver those results, it should be implemented effectively first. And for that, you need an efficient toolchain – a set of tools meant for proper implementation of DevOps. An organization can have more than one toolchain, and the toolchains would depend on the needs of the organization and the objectives of the DevOps ecosystem they are implementing.

No matter how qualified the DevOps team is or no matter how best it’s implemented, a DevOps environment cannot deliver on its promises if the right sets of tools aren’t involved to manage every step of a software development project – right from requirements specification and development to testing, delivery and maintenance.

That said, let’s take a look at a few of the best open source tools that are widely used for DevOps implementation.


Selenium is hugely popular for its automation capabilities, and is primarily leveraged for the automation of web-based apps – both for testing and for performing administrative tasks. Selenium is a favorite of many companies including tech giants like Google and IBM.

Selenium allows:

  • Creation of browser-based regression automation tests and suites
  • Creation of multi-language test scripts
  • Usage of same script across many environments


Those who are familiar with DevOps might have heard of Docker – a container-based platform designed to support continuous integration and continuous deployment. This can be done across a number of infrastructures. Additionally, Docker also simplifies packaging of the final product.

Key features and benefits include:

  • Windows and Linux OS compatibility
  • Deployable on any application stack
  • Capability to deploy up to 20000 containers
  • End-to-end security


Chef is a cloud-based suite of tools aimed at ensuring and enhancing the stability and scalability of the infrastructure. It’s mainly used in DevOps ecosystems to create robust software development environments.

Key features and benefits include:

  • Capability to make configurations testable and automated
  • Consistent configuration assurance
  • Customizable codes depending on requirements
  • Easy migration
  • Compatibility with popular third-party platforms like AIX and FreeBSD


A very popular open source tool, Jenkins is one of the best continuous integration server software available in the market today. It’s deployed on the server that handles the software development activities. Written in Java, Jenkins is also known for being highly customizable regardless of the size and complexity of the project. Furthermore, there are a plethora of plugins and add-ons available making Jenkins a potent tool that delivers the best out of a DevOps environment. Big firms like Capgemini and LinkedIn use Jenkins.

Key features and benefits include:

  • Ease-of-use for DevOps beginners
  • Capability to create scripts that facilitate integration of multiple workflows into one pipeline
  • Support of over 1000 unique plugins
  • Multiple interfaces like CLI, Rest API, and web-based GUI


Puppet is a great tool that is designed primarily for rapid inspection, management, and maintenance of infrastructure. It grew in popularity because of its capability to deploy changes within a short time. Puppet is also primarily preferred as a configuration management tool through the software development lifecycle regardless of the platform involved. Tech giants like Microsoft, Accenture, and Google reportedly use Puppet.

Key features and benefits include:

  • Complete infrastructure automation
  • Rapid deployment
  • Real-time context reporting
  • Conflict detection and resolution


Splunk can be effective as a log comparison tool that allows the DevOps team to compare logs generated by multiple sources in a DevOps ecosystem that spans the complete IT infrastructure of an organization. In addition to collecting logs and facilitating comparison, Splunk also comes with powerful data collection and analyses capabilities; providing organizations with meaningful insights to make strategic decisions. Furthermore, it also helps with seamless IoT integration.

Key features and benefits of the multi-faceted Splunk include:

  • Storage, management, and analysis of data
  • Business analytics
  • Multiple data formats compatibility
  • Log monitoring to detect issues and conflicts


This is a great tool for automating development, testing and deployment, and to manage software development operation’s performance in a DevOps ecosystem. Ansible comes with a number of modules that supports a wide variety of applications. But its truly great feature is its capability to significantly reduce complexity at all stages of the lifecycle.

Key features and benefits include:

  • Push configuration
  • Agentless configuration
  • Faster development process
  • Faster deployment
  • Easier management of complex deployments


Nagios is more like a security guard that keeps watch over the entire system and infrastructure. With Nagios, the DevOps team can monitor databases, applications, networks, logs, and even protocols. Infrastructure issues won’t be a concern anymore with Nagios as they will likely be identified before the risks become threats. Despite being open source, Nagios is entirely secure, reliable, and highly recommended. Renowned companies like Philips, Airbnb etc. use Nagios.

Key features and benefits include:

  • Better monitoring, analysis, and threat detection of mission-critical network infrastructure
  • Management, analysis, and archival of log data
  • Network traffic monitoring
  • Optimized bandwidth utilization
  • Easy log searching
  • Automatic resolution of various issues post detection
  • Facilitates better infrastructure upgrade
  • Streamlines infrastructure maintenance schedules


This list is not a ranking. All 8 tools mentioned above are open source, and have a successful streak when it comes to helping organizations implement an efficient DevOps ecosystem. However, choosing the right set of tools, from this list and from among the many others available, is a different matter entirely. That depends on a number of factors including the teams involved, the infrastructure of the organization, the budget, and even the work culture.

Any DevOps expert would recommend adopting a toolchain that combines several potent features to set up a secure, thriving DevOps ecosystem. And obviously, expertise matters also when it comes to wielding such a toolchain.
