Multy

Multy is an open-source multi-cloud infrastructure platform that enables developers to write cloud-agnostic infrastructure configuration once and deploy it to any cloud provider — AWS, Azure, or GCP — without rewriting code. Using a Terraform provider, Multy abstracts cloud-specific resource definitions so teams can switch providers, avoid vendor lock-in, leverage cloud credits across providers, and improve resilience through multi-cloud redundancy. The platform is self-hostable or cloud-hosted and offers free and business tiers. It is particularly suited for startups wanting to maximize cloud credits and organizations needing geographic or regulatory flexibility in cloud deployment.
