GravityKit
GravityKit folds every GravityView extension into one Pro plugin.
A side-by-side editorial comparison of Chromatic and Railway — 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.
Railway lets other tools hand work to its cloud agents via MCP, the CLI or the API.
Railway's November 13 release opens Cloud Agents to outside callers: tasks can be handed over through MCP, the CLI or the API, `railway ca` sorts threads by status, and Agent Connectors no longer require Priority Boarding. It follows two security-focused releases after the October 21 incident: automatic patching and credential-regeneration redeploys, then workspace token review, HA database password rotation and CLI tracing.

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.

After a month spent on post-incident security, Railway is back to building its agent layer, which started with OpenCode on Cloud Agents and ChatGPT and Claude subscriptions in September. The aim is for agents, not only people, to drive deploys on the platform.
Expect Cloud Agents to get more ways in and more control over what they can touch, likely tied to the workspace token and permission work from early November.
