GravityKit
GravityKit folds every GravityView extension into one Pro plugin.
A side-by-side editorial comparison of Chromatic and Porter — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Porter tightens its security layer with short-lived cloud credentials and zero-trust workload access.
Porter is a Kubernetes-based PaaS targeting engineering teams that want AWS/GCP infrastructure without managing raw k8s. Over the past year it has added GPU job support, temporal-based autoscaling, multiple node groups, and overhauled both application creation and datastore management flows. The most recent release focuses squarely on access control: short-lived cloud credentials and secure cloud access for workloads indicate a move toward zero-trust IAM patterns at the infrastructure level.

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.
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.

The most recent release focuses squarely on access control: short-lived cloud credentials and secure cloud access for workloads indicate a move toward zero-trust IAM patterns at the infrastructure level.
Porter is building a security and compliance layer on top of its deployment primitives — audit logs appear twice across these entries, SOC 2 controls via Drata, short-lived credentials, and workload identity. In parallel, AI-adjacent features have appeared at each release cycle: DeepSeek-R1 model deployment, a Helicone observability add-on, GPU time-slicing, and full GPU Jobs. The two tracks — security hardening and AI infrastructure — are converging toward a production-ready positioning for AI workloads.
The next release will likely push deeper on IAM: workload-level RBAC and service account policies are the logical follow-on to short-lived credentials. Expanded GPU options for training (not just inference) jobs are probable given the incremental progression from time-slicing to full GPU Jobs.
