Chromatic vs Harbor
A side-by-side editorial comparison of Chromatic and Harbor — release velocity, themes, recent moves, and the top alternatives to consider.
Chromatic vs Harbor: at a glance
What is Chromatic?
Chromatic now routes visual reviews to component owners automatically.
Chromatic's October update assigns reviewers automatically from component ownership, merges libraries into one Library view and turns on usage alerts by default. It follows September's flaky-test quarantine and the launch of Chromatic for Vitest Browser Mode.
What is Harbor?
Harbor 2.14.6 RC2 adds Go CVE fixes on top of the regression rollbacks.
Harbor v2.14.6-rc2 keeps the rollbacks from RC1, so webhooks can reach private networks and legacy signer pulls are allowed by default, and adds Go dependency upgrades for High and Critical CVEs, Go 1.26.10, an actual byte limit in the CNAI parser to stop decompression attacks, and a nil-event panic fix in user audit. The 2.15 line got the same rollbacks in 2.15.4 RC1.
Chromatic vs Harbor: editorial side-by-side
Chromatic
5.0INFRA · APIS
Chromatic now routes visual reviews to component owners automatically.
◆ Current state
Chromatic's October update assigns reviewers automatically from component ownership, merges libraries into one Library view and turns on usage alerts by default. It follows September's flaky-test quarantine and the launch of Chromatic for Vitest Browser Mode.
◆ Where it's heading
Chromatic spent most of the year making its visual test signal trustworthy (flake tracing, filtering, quarantine) and widening entry points beyond Storybook to Vitest and React Native. The October release moves to review workflow and spend controls for larger teams.
◆ Prediction
Expect React Native visual testing to move past preview, and more review-routing and ownership features for large design systems.
Harbor
5.0INFRA · APIS
Harbor 2.14.6 RC2 adds Go CVE fixes on top of the regression rollbacks.
◆ Current state
Harbor v2.14.6-rc2 keeps the rollbacks from RC1, so webhooks can reach private networks and legacy signer pulls are allowed by default, and adds Go dependency upgrades for High and Critical CVEs, Go 1.26.10, an actual byte limit in the CNAI parser to stop decompression attacks, and a nil-event panic fix in user audit. The 2.15 line got the same rollbacks in 2.15.4 RC1.
◆ Where it's heading
Harbor's recent releases are split between security hardening and undoing the parts of that hardening that broke real deployments. Both supported lines now carry the rollbacks, and new work is CVE fixes rather than features.
◆ Prediction
Expect 2.14.6 and 2.15.4 finals shortly; the entries don't show a 2.16 feature release yet.
