Ubicloud vs Spinifex: Two Approaches to Open Source Cloud

1. ubicloud

   1 23 12,262 10.0 Ruby

   Open source alternative to AWS. Elastic compute, block storage (non replicated), firewall and load balancer, managed Postgres, K8s, AI inference, and IAM services.

   

   Ubicloud is a YC-backed open source cloud platform written in Ruby. It provides elastic compute via virtual machines, block storage (non-replicated), virtual networking with firewalls and load balancers, managed Postgres with automatic backups and point-in-time restore, Kubernetes, GitHub Actions runner integration, AI inference, and attribute-based access control. You can self-host it on bare metal from providers like Hetzner or Leaseweb, or use their managed service which runs on the same bare metal providers and handles the operational overhead for you.

3. spinifex

   2 13 165 9.9 Go

   Spinifex – Open source AWS-compatible platform for secure edge deployments. Run EC2, VPC, S3, and EBS-like services on bare metal with full control. Built for environments where running in the cloud isn’t an option. Whether you’re deploying to edge sites, private data-centers, or operating in low-connectivity or highly contested environments.

   

   Spinifex is an open source AWS-compatible cloud platform, written in Go and AGPL-3.0 licensed, that runs on standard Linux bare metal hardware you own and operate. Rather than defining a new cloud API, it implements the AWS API itself, covering EC2, S3, IAM, EKS, and the rest of the common AWS service surface, so the Terraform configs, CLI scripts, IAM roles, and SDK integrations your team has already written work against it without modification. The endpoint changes; the tooling doesn't.
