Harbor vs Redocly: at a glance
What is Harbor?
Harbor 2.16 RC1 brings official arm64 builds, custom project roles and smarter proxy caching.
Harbor spent September and October on security patch candidates and rolling back defaults that broke webhooks and legacy signer pulls. The first 2.16.0 candidate is the first feature release in that window. It adds full amd64 and arm64 builds, custom project roles in the UI, proxy-cache repository filters and referrer API proxying, and member audit events.
What is Redocly?
Redocly's reunite.agent gets per-duty cron schedules, rules and source repos.
Redocly shipped three Reunite releases and a config release on Oct 28. The feedback and discovery duties in reunite.agent can now each run on their own UTC cron trigger, follow their own rules and read only listed source repositories. SCIM provisioning now accepts identity-provider groups of any size, where pushes over 1,000 members used to fail. @redocly/config 0.69.0 also adds per-rule impact settings for the experimental diff command.

Harbor
5.0INFRA · APIS
Harbor 2.16 RC1 brings official arm64 builds, custom project roles and smarter proxy caching.
◆ Current state
Harbor spent September and October on security patch candidates and rolling back defaults that broke webhooks and legacy signer pulls. The first 2.16.0 candidate is the first feature release in that window. It adds full amd64 and arm64 builds, custom project roles in the UI, proxy-cache repository filters and referrer API proxying, and member audit events.
◆ Where it's heading
The 2.16 line shifts Harbor from patching toward enterprise registry features: finer RBAC, deeper audit trails, and a proxy cache that handles OCI referrers such as signatures and SBOMs. Multi-arch builds make Harbor a straightforward fit for arm64 clusters. Security fixes keep landing alongside, so the 2.14 and 2.15 patch lines will likely continue.
◆ Prediction
Expect further 2.16.0 release candidates before GA, plus more 2.14.x and 2.15.x patch tags. Whether custom roles get a matching API-level story is not yet clear from these notes.
Redocly
6.3INFRA · APIS
Redocly's reunite.agent gets per-duty cron schedules, rules and source repos.
◆ Current state
Redocly shipped three Reunite releases and a config release on Oct 28. The feedback and discovery duties in reunite.agent can now each run on their own UTC cron trigger, follow their own rules and read only listed source repositories. SCIM provisioning now accepts identity-provider groups of any size, where pushes over 1,000 members used to fail. @redocly/config 0.69.0 also adds per-rule impact settings for the experimental diff command.
◆ Where it's heading
Two threads run together: an agent inside Reunite that does recurring docs work (feedback and discovery) and is gaining scheduling and scoping controls, and enterprise plumbing such as SCIM scale, Git token rotation and permission fixes. Last week's configurable docs MCP server points the same way, with Redocly adding AI surfaces and making them configurable in redocly.yaml.
◆ Prediction
Expect more reunite.agent duty types or options in @redocly/config, and the experimental diff command moving toward a documented API-change check.
