GravityKit
GravityKit folds every GravityView extension into one Pro plugin.
A side-by-side editorial comparison of Firecracker and KrakenD — release velocity, themes, recent moves, and the top alternatives to consider.
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.
KrakenD's community edition is shipping only dependency bumps.
The two tracked KrakenD releases are patch releases of the community edition. 2.13.10 in August moved to Go 1.26.7, and 2.13.11 in September bumped the gRPC and RabbitMQ client libraries.

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.
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.

The open-source gateway is in maintenance mode in this feed, kept current on Go and dependencies. Two entries are too few to say where the product is heading.
Unclear from these entries; more dependency patch releases are the only pattern visible.
