Bitbucket Pipeline Runner

Scalable Docker-based Bitbucket Pipeline runners for Kubernetes and Docker Swarm

Self-hosted Bitbucket Pipeline runners with autoscaling on Kubernetes/Docker Swarm. Eliminates cloud runner costs, enables IP-restricted deployments, and provides custom build environments with persistent caching for faster builds.

Zero Runner Costs

Eliminate pipeline minute charges and enable secure, custom build environments for every project.

Problem

Bitbucket’s cloud runners became expensive at scale for teams with high pipeline volume. Some deployment targets required IP whitelisting impossible with shared cloud runners. Custom build tools needed per-project installation, slowing every pipeline run.
