Open-source Huawei Cloud alternatives

Sealos describes itself as an AI-native cloud operating system built on Kubernetes. It aims to cover the whole application lifecycle in one platform, from development in cloud IDEs to production deployment and day-to-day management, and it targets teams building AI applications, SaaS platforms, managed databases and microservice architectures.

Core pieces include Devbox cloud development environments that can be opened from editors such as VS Code and Cursor, managed MySQL, PostgreSQL, MongoDB and Redis databases, S3-compatible object storage, and an App Launchpad for deploying Docker images. An app store offers one-click deployment of larger applications, and workspace-based multi-tenancy supports enterprise use. Full Kubernetes remains accessible underneath.

Sealos is written mainly in TypeScript and Go and runs on Kubernetes. Repository topics point to cluster installation features such as high-availability Kubernetes through kubeadm, and the project offers a hosted cloud at sealos.io. The repository lists the license as 'Other', so check the license file for the exact terms.

Ubicloud is an open-source cloud platform designed to run on any infrastructure, described by its authors as an open alternative to cloud providers in the way Linux is to proprietary operating systems. It delivers infrastructure-as-a-service capabilities on top of bare-metal hosts, for example Hetzner, Leaseweb and AWS Bare Metal.

Its services include elastic compute, non-replicated block storage, firewalls and load balancers, managed Postgres, Kubernetes, AI inference and IAM. A control plane takes leased bare-metal Linux machines, prepares them for cloud use, and then lets you provision and manage resources through a cloud console. The project is written in Ruby and topics also mention GitHub Actions runners.

You can use the managed platform at console.ubicloud.com without installing anything, where the underlying provider's price and location benefits are passed on to you, or build your own cloud by leasing servers and running the control plane yourself. Ubicloud is licensed under AGPL-3.0. The quick-start flow is currently described for Hetzner machines running Ubuntu 24.04.
