A side-by-side editorial comparison of Chromatic and Prowler — release velocity, themes, recent moves, and the top alternatives to consider.
Chromatic vs Prowler: at a glance
What is Chromatic?
Chromatic for React Native takes visual tests to iOS simulators and Android emulators.
Chromatic for React Native, previewed in May, now has its own announcement: React Native Storybook stories become visual tests that run in parallel on cloud iOS simulators and Android emulators. It follows October's automatic reviewer assignment and combined Library view, and September's flaky-test quarantine and Vitest Browser Mode launch.
What is Prowler?
Prowler 5.48 stops waiting for the next scan: it watches AWS live and can fix what breaks.
Prowler ships a minor release every one to two weeks. 5.48.0 adds Prowler Realtime for AWS in Prowler Cloud: it reads CloudTrail events as they happen, runs a targeted check on the touched resource and then alerts, opens a Terraform pull request or fixes the resource directly, depending on each account's policy. 5.47 had reduced provider setup to one step and made Issues lead with a verdict and an attack path.

Chromatic
6.3INFRA · APIS
Chromatic for React Native takes visual tests to iOS simulators and Android emulators.
◆ Current state
Chromatic for React Native, previewed in May, now has its own announcement: React Native Storybook stories become visual tests that run in parallel on cloud iOS simulators and Android emulators. It follows October's automatic reviewer assignment and combined Library view, and September's flaky-test quarantine and Vitest Browser Mode launch.
◆ Where it's heading
Chromatic spent the year making its visual test signal trustworthy and widening entry points beyond web Storybook, first to Vitest and now to mobile. Review routing and spend controls are arriving alongside for larger teams, so the product is being fitted to organizations that run many test surfaces at once.
◆ Prediction
Expect a monthly changelog to spell out React Native limits and billing, since the announcement states neither. Further review-routing and ownership work for large design systems is the other likely thread.
Prowler
6.3INFRA · APIS
Prowler 5.48 stops waiting for the next scan: it watches AWS live and can fix what breaks.
◆ Current state
Prowler ships a minor release every one to two weeks. 5.48.0 adds Prowler Realtime for AWS in Prowler Cloud: it reads CloudTrail events as they happen, runs a targeted check on the touched resource and then alerts, opens a Terraform pull request or fixes the resource directly, depending on each account's policy. 5.47 had reduced provider setup to one step and made Issues lead with a verdict and an attack path.
◆ Where it's heading
Prowler is moving from a periodic scanner toward a response system: partial re-scans in 5.44, exploitability verdicts in 5.46-5.47, and now event-driven detection with reversible auto-remediation. The paid cloud tier carries most of this, with the open scanner feeding it.
◆ Prediction
Expect Realtime to extend to Azure or GCP event feeds and more checks to gain automatic fixes.
