GravityKit
GravityKit folds every GravityView extension into one Pro plugin.
A side-by-side editorial comparison of Port and Chromatic — release velocity, themes, recent moves, and the top alternatives to consider.
Port now runs Claude agents end to end, acting as the user who started them.
Port's October release lets workflows create, run and archive Claude Managed Agents, stream their progress into the run log and use their output, with Port MCP access granted as the triggering user or a service account. Identity Propagation makes self-hosted GitHub, GitLab and Azure DevOps actions run with the triggering user's own credentials. Dashboards gain saved filter presets, advanced filter rules and a Board view in closed beta, and new orgs get a guided Solutions Onboarding.
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.

Port has spent 2026 turning its catalog into a governed place where both people and agents act. September let other apps inherit Port permissions; October carries the user's identity all the way into third-party tools and into agents, so audit logs show who really acted.
Expect Identity Propagation to reach more integrations beyond the three self-hosted ones, and more agent providers to get the same end-to-end lifecycle support Claude has now.

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.
