15 best continuous deployment tools in 2026 — which one fits your stack and team

# What this guide covers This brief summarizes Hostinger's list of 15 continuous deployment tools (published Sep 2026). It explains when to choose each tool, where it deploys, and whether you must run infrastructure such as self-hosted runners, agents, or platform components.

# CI/CD basics

# When to choose which tool

• Use GitHub Actions when your code already lives on GitHub and you want workflows in the same place. It supports GitHub-hosted runners or self-hosted runners when you need private-network or special hardware access.
• Use GitLab CI/CD if you prefer integrated source control and CI/CD inside GitLab, including self-managed runners or self-hosted GitLab.
• Choose Argo CD or Flux CD for Kubernetes-only GitOps: both apply Git as the source of truth for cluster state and run inside the cluster.
• Prefer Jenkins when you need full control over self-hosted automation and can script deployments to any server or cloud.

• Use Google Cloud Deploy for targets like GKE or Cloud Run in Google Cloud.

• Pick Octopus Deploy when you build elsewhere and promote releases through multiple environments, including on-premises customer sites.
• Choose Spinnaker for platform teams managing deployments across major cloud providers and Kubernetes.
• CircleCI offers managed CI/CD with options for self-hosted jobs or runners when needed.
• Use Vercel or Railway when you want hosting and deployment managed together for front-end/Next.js (Vercel) or small teams needing unified hosting, deployment, and basic database services (Railway).
• Hostinger Web Apps Hosting targets smaller teams wanting managed hosting plus deployment handled together.

# Deployment infrastructure considerations

• Managed platforms (Vercel, Railway, Hostinger Web Apps Hosting) require no self-hosted runners or agents.

• GitHub Actions, GitLab CI/CD, CircleCI can run on provider-hosted runners or on servers you manage (self-hosted runners/agents) when you need custom access.
• Kubernetes-native tools (Argo CD, Flux CD) run inside the cluster and are Kubernetes-only solutions.

# Quick reference list of the 15 tools mentioned GitHub Actions, GitLab CI/CD, Argo CD, Hostinger Web Apps Hosting, Jenkins, Azure Pipelines, AWS CodePipeline, Google Cloud Deploy, Harness Continuous Delivery, Octopus Deploy, Flux CD, CircleCI, Spinnaker, Vercel, Railway.

# How to decide in practice Start by matching three anchors: where your source code lives, where your app must run, and how much infrastructure your team can operate. If code is on GitHub and you can accept cloud-hosted runners, start with GitHub Actions. If you run Kubernetes and prefer GitOps, evaluate Argo CD or Flux CD. If you want minimal ops and host front-end apps, choose Vercel or Railway.
