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 Merge?
Merge adds security and infra connectors and a half-price flex tier on its gateway.
Merge ships weekly across Agent Handler, Gateway and Unified. The latest Agent Handler batch adds AWS Redshift, CyberArk Identity, Drata, Elasticsearch, JumpCloud, MyCase, Splunk and Terraform, OAuth 2.0 for eight existing connectors, and a Registered Users tab with CSV export. Gateway adds Baseten decision models on /v1/decisions, a flex tier on Particle that bills at half every rate, and key-pinned projects that let customers tighten data-retention and region settings. Unified's UKG Ready leave-of-absence syncs now run about 30 times faster with 20 times fewer API requests.
Chromatic vs Merge: editorial side-by-side
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.
Merge
5.0INFRA · APIS
Merge adds security and infra connectors and a half-price flex tier on its gateway.
◆ Current state
Merge ships weekly across Agent Handler, Gateway and Unified. The latest Agent Handler batch adds AWS Redshift, CyberArk Identity, Drata, Elasticsearch, JumpCloud, MyCase, Splunk and Terraform, OAuth 2.0 for eight existing connectors, and a Registered Users tab with CSV export. Gateway adds Baseten decision models on /v1/decisions, a flex tier on Particle that bills at half every rate, and key-pinned projects that let customers tighten data-retention and region settings. Unified's UKG Ready leave-of-absence syncs now run about 30 times faster with 20 times fewer API requests.
◆ Where it's heading
Agent Handler's catalog is moving from sales and productivity apps toward security and infrastructure tools, while Gateway competes on price and on customer controls. Unified gets steady mapping and sync fixes rather than new categories.
◆ Prediction
Expect more security and infrastructure connectors in Agent Handler and further service tiers or pricing options on Gateway, given the flex tier's arrival.
