Firecracker vs Chromatic: 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 Chromatic?
Chromatic opens a beta that lets coding agents read and fix visual test failures.
Chromatic spent 2026 moving beyond Storybook: Vitest Browser Mode launched in September and React Native visual testing on cloud iOS and Android devices was announced in October. On November 5 it opened Chromatic for agents in beta, where a coding agent reads the test results, fixes the regressions and repeats until the pull request is ready.

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.
Chromatic
7.5INFRA · APIS
Chromatic opens a beta that lets coding agents read and fix visual test failures.
◆ Current state
Chromatic spent 2026 moving beyond Storybook: Vitest Browser Mode launched in September and React Native visual testing on cloud iOS and Android devices was announced in October. On November 5 it opened Chromatic for agents in beta, where a coding agent reads the test results, fixes the regressions and repeats until the pull request is ready.
◆ Where it's heading
Chromatic is turning from a review screen for humans into a feedback loop that coding agents can act on. Each new entry point (Vitest, React Native, now agents) widens who and what sends work through its visual tests.
◆ Prediction
The beta post is brief, so how agents connect is unclear; expect a follow-up naming the supported agents and moving this toward general availability.
