Exe.dev has launched a developer preview of its new VM hosting service, allowing users to access virtual machines via SSH at the address `ssh exe.dev`. The service aims to simplify the process of managing multiple virtual machines, a need that arose during the development of sketch.dev. Users can customize how their resources—CPU and RAM—are allocated across their VMs. For example, a user could maintain 20 idle VMs that activate infrequently, depending on their requirements. Key features include sub-second startup times for full Ubuntu machines or any compatible container image. Users can install tools like Docker Compose on these VMs. The platform also offers persistent disk storage, with enhancements planned for the future. Security is a priority; VMs are private by default, and users can share access through links similar to Discord's approach. The service manages TLS and authentication automatically, ensuring only authorized users can reach their HTTP services. Exe.dev emphasizes an agent-friendly environment, allowing users to treat their VMs as sandboxes for various applications. The team plans to share more details about the technology and projects that make up the service in the coming weeks. The combination of persistent, private, and quickly starting VMs aims to redefine cloud computing efficiency and user experience.
