What is Firecracker?

Firecracker can now run microVMs on Nitro instead of KVM, with the same API.

Firecracker is the open-source microVM monitor behind AWS Lambda and Fargate. 2026 brought PCI virtio hotplug in developer preview (1.16), virtio device reset and richer metrics (1.17), and now 1.18.0 adds Nitro Sandboxes: Firecracker can drive the Nitro Enclaves driver instead of /dev/kvm to launch VMs the Nitro Hypervisor carves out of the parent EC2 instance. The existing API, jailer and virtio device model stay the same, and a new PUT /enclave endpoint selects confidential or direct mode.

What is SpinupWP?

SpinupWP now writes DNS records for you, starting with Cloudflare and Route 53.

SpinupWP is moving server and site work out of SSH and third-party consoles into its own dashboard and API. September completed the site-settings API, October's dashboard rebuild added bulk actions, labels and filters, and on November 3 SpinupWP began managing A records through Cloudflare and Route 53. The API now also lists and manages SSH keys for accounts and site users.

Firecracker can now run microVMs on Nitro instead of KVM, with the same API.

◆ Current state

Firecracker is the open-source microVM monitor behind AWS Lambda and Fargate. 2026 brought PCI virtio hotplug in developer preview (1.16), virtio device reset and richer metrics (1.17), and now 1.18.0 adds Nitro Sandboxes: Firecracker can drive the Nitro Enclaves driver instead of /dev/kvm to launch VMs the Nitro Hypervisor carves out of the parent EC2 instance. The existing API, jailer and virtio device model stay the same, and a new PUT /enclave endpoint selects confidential or direct mode.

◆ Where it's heading

The project is widening what a Firecracker microVM can be without changing how operators drive it: hotplug and reset made the VM lifecycle more flexible, and Nitro support makes the hypervisor backend swappable. Patch releases keep landing on several stable lines at once, so the maintainers are supporting older minors while the feature surface grows.

◆ Prediction

Expect 1.18.x patches that fix Nitro Sandbox edge cases and documentation on which devices and snapshot features work in confidential mode; the release does not say whether Nitro support will leave preview or reach feature parity with KVM.

5.0

SpinupWP now writes DNS records for you, starting with Cloudflare and Route 53.

◆ Current state

SpinupWP is moving server and site work out of SSH and third-party consoles into its own dashboard and API. September completed the site-settings API, October's dashboard rebuild added bulk actions, labels and filters, and on November 3 SpinupWP began managing A records through Cloudflare and Route 53. The API now also lists and manages SSH keys for accounts and site users.

◆ Where it's heading

Each release removes one more step a WordPress operator used to do elsewhere: PHP settings, software updates, disabling sites, and now DNS. The pattern points to a full site lifecycle, from creation through deletion, handled inside SpinupWP.

◆ Prediction

More DNS providers are the likely next step, since the launch says it is starting with two; whether DNS management also reaches the API is not shown in the entries.
