zero review
A free, open-source CLI for health-checked Docker deployments on a server you control.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
zero is an open-source command-line tool from Codebeam for deploying Docker images to a Linux server you control. It is aimed at solo operators and small teams that prefer managing their own deployment host over using a managed platform. The tool installs an agent on a VPS, supports single-command deployments and Docker Compose applications, and includes automatic HTTPS, temporary preview deployments, webhooks, logs, and metrics. Its scope is intentionally centered on server-level deployment rather than team management or multi-node orchestration.
Rollback safety is the central strength. zero health-checks a new container before switching traffic, and its rollback command restores the previous deployment. Each app retains its last 10 deployments for rollback. Health checks support deployment and rollback safety, but they do not automatically initiate a rollback: an operator must run the rollback command. Preview deployments expire automatically, and signed webhooks can trigger image deployments. This approach fits teams that want a direct recovery path while remaining responsible for their own server and deployment decisions.
The open-source tool has no platform fees, while hosting costs are separate. Its integrations include GitHub Actions, Docker Hub, GitHub Container Registry, Claude Code, and Claude Desktop; it can also stream application and server logs and show live CPU, memory, and network metrics. Documentation is the listed support channel. Choose zero if a self-managed, single-server Docker workflow and manual operational control suit your team. Teams needing multi-node orchestration, approval controls, audit logs, or automatic rollback triggers should look for a tool built around those requirements.
