Xenmaster's 2026 DevSecOps Tools Catalog

Xen MasterXen Master85 appsUpdated
Copy a direct link to this comment to your clipboard

This list is an update to the list I created seven years ago https://alternativeto.net/lists/8013/devops-systems/ which focused on the SRE/DevOps component of infrastructure for web applications. The web and development world has changed a lot since then and rather than re-write history, decided to create a new list based on current patters and shifts in enterprise environments. These details are based on both what I've seen in the professional world as well as for hobbyists and web development enthusiasts who run their own projects. The general pattern for these tools will cover three main points for each function:

  • Self Hosted Option
  • Third-Party Service Option
  • AWS Option

I also cover any GUI interfaces available for folks who don't want to interact with these services using a terminal.

In addition to consulting the documentation for each of the tools below, I'd like to shout out the following projects which also played a big part in informing the overall structure of this list:

  • Jeff Delaney's 100 Second Videos: https://www.youtube.com/@Fireship
  • Kamran Ahmed's Roadmaps: https://roadmap.sh
  • Stack Overflow's Developer Survey: https://survey.stackoverflow.co/2025/
  • Arjay the Dev's Videos and Website: https://www.arjaythedev.com/

This is a no-AI zone since I am unfamiliar with these tools. Nor do I wish to change that.

Code Deploy

Part 2 of the code building process focused around deploying code through a continuous integration process rather than using manual deployments. Many of these pipelines also come with build checks and automated testing to ensure better ease of use.

Code Artifacts

Part 3 of the code building process includes storing the results of builds, usually through an artifact management process.

  1. Harbor icon

Container Registry

Part 4 of the code building process revolves around the container management process. Different from orchestration from an ops perspective, this is more around managing deployed container builds, not just code based artifacts.

  1. Docker Hub is a cloud-based registry service which allows you to link to code repositories, build your images and test them, stores manually pushed images, and links to Docker Cloud so you can deploy images to your hosts.

Infrastructure Management (IaC)

Part 5 and last part of the code build process, this focuses more on managing cloud infrastructure by provisioning infrastructure using declarative code rather than the native deployment console (although that is still an option.)

  1. OpenTofu icon

Service Mesh

As enterprises have recently started to move away from microservices architecture, I am seeing fewer service mesh management tools, but the below are what I still see in the wild today.

  1. Istio icon
     Like

    Istio is an open platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. Istio's control plane provides an abstraction layer over the underlying cluster management platform...

Services - Serverless

This has become less of a trend lately in my observation, although I do see some stacks touting Functions As A Service (FaaS) as a goal.

Services - Observability

Availability is often one of the highest stakes components of a modern online service stack. This was dominated by Splunk and the ELK stack (now known as the ElasticStack), but I've seen more and more companies transition to the Grafana stack.

  1. Grafana Loki is a horizontally-scalable, highly-available, multi-tenant log aggregation system inspired by Prometheus. It is designed to be very cost effective and easy to operate. It does not index the contents of the logs, but rather a set of labels for each log stream.
