Firecracker vs Gloo Gateway: at a glance
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 Gloo Gateway?
Gloo Gateway 1.20.30 reverses parts of 1.20.29 that dropped rate limits and ext-auth updates
Gloo Gateway maintains the 1.19, 1.20 and 1.21 lines in parallel. The 7 November 1.20.30 release fixes regressions from 1.20.29: rate-limit rules could vanish after a Settings or namespace change, and a failed reconcile stopped AuthConfig and Secret changes, including deleted API keys, from reaching the ext-auth server. 1.19.27 only bumps a compression library.

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.

Gloo Gateway 1.20.30 reverses parts of 1.20.29 that dropped rate limits and ext-auth updates
◆ Current state
Gloo Gateway maintains the 1.19, 1.20 and 1.21 lines in parallel. The 7 November 1.20.30 release fixes regressions from 1.20.29: rate-limit rules could vanish after a Settings or namespace change, and a failed reconcile stopped AuthConfig and Secret changes, including deleted API keys, from reaching the ext-auth server. 1.19.27 only bumps a compression library.
◆ Where it's heading
The 1.20 line is going through repeated reliability fixes around restarts and setup re-runs, and each fix has changed behaviour enough to need a follow-up. Work is concentrated on control-plane correctness rather than new features.
◆ Prediction
Expect a 1.21 backport of the 1.20.30 setup-run and ext-auth fixes, since the earlier stale-endpoint fix shipped across all three lines.
