16 Top Continuous Delivery Tools for 2024

continuous delivery tools

Continuous delivery (CD) is the process of automating software releases into production environments. Instead of waiting for an engineer to manually make deployments, CD implements systems that release changes as they’re integrated into your product.

Utilizing CD makes your DevOps loop more efficient and responsive. Automating the software delivery process allows developers to focus on creating meaningful new changes instead of tedious chores like preparing environments and launching releases.

Plenty of great tools can help you start implementing CD. In this guide, we’ll explore 16 of the top available options in 2024.

What is Continuous Delivery (CD)?

Continuous delivery describes the process of automatically deploying new code changes after they’ve been integrated into your system. It’s a logical extension of continuous integration (CI); they are usually combined as a single CI/CD pipeline.

 

Whereas CI focuses on the build and test stages of the software development lifecycle, CD considers how code that’s ready to ship actually reaches production. It utilizes tools and processes including GitOps, IaC, and containers to deploy changes as soon as they’re ready, without requiring any developer intervention. The solution will continually detect new changes, and apply any actions required to release them to your users.

Key features to look for in a continuous delivery tool

Continuous delivery tools come in many different flavors. It’s important to find the best option for your projects so you can be confident your changes will roll out reliably. Here are some of the most important characteristics:

  • Automation: CD solutions need to be capable of automating your entire deployment workflow. Tools that only cover part of the process or demand developer input to complete key stages will offer limited effectiveness.
  • GitOps compatibility: CD and GitOps are closely linked. GitOps tools use versioned files in a Git repository to define the state of your deployments, then continually reconcile the declared configuration to your live resources. Choosing a CD solution that’s based around GitOps can reduce setup complexity and help prevent configuration drift.
  • Customization options: Customizable tools are easier to integrate with your existing workflows. They also reduce the risk of becoming locked into a particular solution, making it easier to scale your delivery systems and adopt new technologies.
  • Integrations: CD implementations should be compatible with the rest of your toolchain, including the VCS solutions, IaC providers, and cloud services you use. Leading tools will support native integrations with popular choices in these categories.
  • Ease of use: CD should support DevOps teams as they manage the software deployment process. Tools that are simple to configure, maintain, and monitor will be more accessible than those with steep learning curves or specialist concepts.
  • Scalability: Choosing scalable tools is crucial to ensure your CD workflows continue to perform predictably as deployment frequency increases and you launch additional environments. Tools designed for cloud-native operation are generally more scalable than those that must be operated locally.
  • Security and compliance: CD solutions come into direct contact with your source code and live infrastructure. It’s vital they include adequate security protections and are compatible with your project’s compliance standards. Look for proven options that have passed security audits.
  • Strong official or community support: Comprehensive support options ensure you can effectively configure and maintain your tools. Look for actively monitored bug trackers, community forums, and developer contact methods that let you get help quickly if you experience a problem with your implementation.

Keep these criteria in mind as you evaluate different continuous delivery tools. Although you might have to compromise, the most effective solutions should score highly across several factors.

1. Spacelift

Spacelift is not exactly a DevOps continuous delivery tool, but it allows you to connect to and orchestrate all of your infrastructure tooling, including infrastructure as code, version control systems, observability tools, control and governance solutions, and cloud providers.

continuous delivery tools spacelift

With Spacelift, you can provision, configure, and govern with one or more automated workflows that orchestrate Terraform, OpenTofu, Terragrunt, Pulumi, CloudFormation, Ansible, and Kubernetes. 

Spacelift was built with DevOps/platform engineers in mind, but it evolved into the go-to platform for software engineers because they can increase their velocity with self-service infrastructure that implements all their organization’s guardrails. It greatly enhances collaboration among engineers, offering them a central location to make infrastructure-related decisions.

Key features

  • Flexibility: Bring your own image, control what happens before and after every runner phase, and integrate with any third-party tool you want.
  • VCS integration: Integrates with popular VCS providers such as GitHub, GitLab, BitBucket, and Azure DevOps.
  • Policies at multiple decision levels: You can control how many approvals you need for a run, what resources can be created, what parameters those resources can have, what happens when a pull request is open, and where to send your notifications data.
  • Cloud integrations: Dynamic temporary credentials for AWS, Azure, and GCP.
  • Drift detection and remediation: Ensures reliability of your infrastructure by detecting and remediating drift.
  • Contexts: Reusable Environment variables and Mounted files.
  • Self-service infrastructure with Blueprints: You can define infrastructure templates that can be easily deployed. These templates can have policies/integrations/contexts/drift detection embedded inside them for reliable deployment.
  • Stack dependencies: Create dependencies between stacks and pass outputs from one to another. This can help to build an environment promotion pipeline easily.
  • Visibility: Easily see all the deployed resources and details about them.
  • Self-hosted capability: Spacelift can be self-hosted in AWS and AWS Gov Cloud.

GitHub Actions is the CI/CD solution integrated with GitHub repositories. You can use it to implement automated workflows that run in response to repository events, such as pushing new code or merging a pull request.

continuous delivery tools github actions

Because Actions isn’t a dedicated CD tool, it can require more configuration to connect your cloud platforms and write your deployment scripts. However, the flip side is that Actions is highly flexible and can be used to implement any kind of process you require. As it comes bundled with GitHub repos, it’s also accessible and removes the need to learn a completely different tool. 

The service is supported by a vast catalog of publicly available actions that you can use to compose your pipelines.
