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.

What is WireMock?

WireMock 4.0 beta.42 can record every request header, still in beta.

WireMock is the standard Java tool for mocking HTTP APIs, and its 4.0 line is still in beta. After a quiet month, beta.42 and beta.43 arrived on November 12 and 13: recording can now capture all request headers with exclusions, a new extension point lets code react to served messages, and the rest is Dependabot bumps.

7.5

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.

5.0

WireMock 4.0 beta.42 can record every request header, still in beta.

◆ Current state

WireMock is the standard Java tool for mocking HTTP APIs, and its 4.0 line is still in beta. After a quiet month, beta.42 and beta.43 arrived on November 12 and 13: recording can now capture all request headers with exclusions, a new extension point lets code react to served messages, and the rest is Dependabot bumps.

◆ Where it's heading

The 4.0 betas are still mostly fixes and dependency updates, with small additions to recording and message channels. Nothing signals a final release yet.

◆ Prediction

Expect more numbered betas with recording and message-channel fixes; when 4.0 goes final is not visible from these entries.
