Best Kubernetes CI/CD tools: Top 8 solutions in 2025

Octopus Deploy is a sophisticated, best-of-breed cContinuous dDelivery (CD) platform for modern software teams. It offers powerful release orchestration, deployment automation, and runbook automation while handling the scale, complexity, and governance expectations of even the largest organizations with the most complex deployment challenges.

General features of Octopus:

• Reliable risk-free deployments: Octopus lets you use the same deployment process across all environments. This means you can deploy to production with the same confidence you deploy to everywhere else. Built-in rollback support also makes it easy to revert to previous versions.
• Deployments at scale: Octopus is the only CD tool with built-in multi-tenancy support. Deploy to two, ten, or thousands of customers without duplicating the deployment process.
• One platform for DevOps automation: Runbooks automate routine and emergency operations tasks to free teams for more crucial work. They can also be used to provide safe self-service operations to other teams.
• Streamlined compliance: Full auditing, role-based access control, and single-sign- on (SSO) as standard to make audits a breeze and to provide accountability, peace of mind, and trust.

Kubernetes-specific features:

• Environment progression: Spend less time updating manifest files or writing custom scripts with built-in environment modelling and progression.
• Single pane of glass: Get everything you need in one place, such as live status, deployment history, logs, and manifests across all clusters and environments.
• Enterprise-grade compliance: Use role-based access controls (RBAC) to handle access to applications and environments, and built-in ITSM integrations for change management.
