Chromatic vs Dagger
A side-by-side editorial comparison of Chromatic and Dagger — release velocity, themes, recent moves, and the top alternatives to consider.
Chromatic vs Dagger: 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 Dagger?
Dagger now runs the engines for you and reports CI per test, not per job.
Dagger's recent changelog holds two product moves. Cloud Engines, in September, are hosted engines with scale-out, distributed cache and observability, billed only for resources used, with Dagger claiming repeat work costs 5× less. Test-native CI, in October, tracks individual tests, so a failure names the test and only that test is run again. Around them sit cache and plumbing changes, including COPY steps that depend only on the files they copy and SSH-mounted remote filesystems.

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.
Dagger
2.5INFRA · APIS
Dagger now runs the engines for you and reports CI per test, not per job.
◆ Current state
Dagger's recent changelog holds two product moves. Cloud Engines, in September, are hosted engines with scale-out, distributed cache and observability, billed only for resources used, with Dagger claiming repeat work costs 5× less. Test-native CI, in October, tracks individual tests, so a failure names the test and only that test is run again. Around them sit cache and plumbing changes, including COPY steps that depend only on the files they copy and SSH-mounted remote filesystems.
◆ Where it's heading
Both moves rest on the same idea: treat the pipeline as a graph Dagger can see into, then avoid repeating work. A layer cache that survives unrelated file changes, per-test reruns and a distributed cache all reduce what a run must redo. Cloud Engines turn that saving into something sold, the one metered offering in these entries.
◆ Prediction
Expect Test-native CI and Cloud Engines to converge, with per-test reruns offered through hosted engines. That link is inferred from the two launches; the entries neither state it nor give pricing detail.
