Open Source Amazon EC2 Alternatives
A curated collection of the 1 best open source alternatives to Amazon EC2.
The best open source alternative to Amazon EC2 is Spinifex. If that doesn't suit you, we've compiled a ranked list of other open source Amazon EC2 alternatives to help you find a suitable replacement.
Amazon EC2 alternatives are mainly Cloud Infrastructure Management but may also be Storage Solutions. Browse these if you want a narrower list of alternatives or looking for a specific functionality of Amazon EC2.
An AWS-compatible cloud platform for teams running EC2, S3, VPC and IAM workloads on their own bare metal, edge or Neocloud hardware.

Spinifex recreates the AWS service surface on infrastructure you control. Software written for EC2, EBS, S3, VPC and IAM keeps working unchanged, because the AWS CLI, the SDKs and Terraform talk to Spinifex the way they talk to AWS. What changes is where the workload runs, not what it is.
Every API call is authenticated at a gateway, published to a NATS subject and answered by whichever daemon claims it. Daemons hold no state, so scaling out means starting more. There is no etcd, no Kubernetes and no external control plane, so a cluster keeps serving through disconnection.
The platform is assembled from several Go services and the open source pieces around them.
- Spinifex: VM orchestration over QEMU driven through the QMP interface, with EKS, ECS, ECR and RDS built on that same instance layer.
- Viperblock: block storage with write ahead logs on local NVMe, replicated across nodes and exposed over NBD or virtio-blk.
- Predastore: S3 compatible object storage with SigV4 auth, multipart uploads and Reed-Solomon erasure coding across nodes.
- Northstar: authoritative DNS for cluster service discovery and public records, with zones kept as readable TOML files.
- Networking: OVN backs VPC networking and security groups, while HAProxy and nginx serve the load balancer APIs.
The same platform deploys in three shapes, a partner Neocloud with GPU capacity, a multi-node cluster in your own data center, or an edge site running air gapped. It is Go and AGPL 3.0, with a 72 hour hosted sandbox for pointing an existing workload at it first.
