01
Cost is a core design constraint
Usage is calculated in 2-minute micro-buckets and containers automatically sleep when idle — because the most affordable resource is one that isn't running. Billing is integral to our product, not an afterthought.
About
Cloud infrastructure withthe headaches left out.
Hubfly space is a container platform designed around a single core idea: a project should be a complete boundary. Everything your application needs to run — networking, storage, image registries, team access, and billing — stays in one place.

One project model
Most cloud providers force you to build your stack out of disconnected pieces. You start with compute, piece together networking, attach block storage, configure a container registry, wire up permissions, and then try to decipher the bill. It works, but almost nobody can keep all that complexity in their head.
We built Hubfly space around the concept of a project. Containers inside a project communicate privately, share persistent volumes and custom domains, inherit environment settings, and bill against a single clear balance. Scaling to production is as simple as switching a tier, not rebuilding your infrastructure.
Under the hood, your applications run as cells — native Linux processes isolated by cgroups v2 and custom namespaces, without a heavy container daemon in the way. That's what allows our scale-to-zero model to be cheap enough for a generous free tier, and why tenant isolation is enforced directly by the Linux kernel.
Principles
Four core principles behind how we build.
02
Private until you choose to expose
Your services start completely unreachable. Opening a port, attaching a domain, or bringing up a tunnel is always an explicit action you take, never a default you have to undo.
03
One unified project boundary
Deployments, storage volumes, custom domains, container images, team permissions, and billing live together inside your project. There's only one place to check when debugging.
04
Isolation at the kernel level
Workloads run in dedicated namespaces with root remapped to an unprivileged host UID and Linux capabilities dropped by default. Security is enforced far below the control plane.
Architecture
Nine modular components, one cohesive platform.
Hubfly space isn't a monolith. Each component does one job exceptionally well, working together to deliver a reliable cloud experience.
