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.

What is Scalar?

Scalar's mock server learns event-driven APIs while the reference UI picks up localization

Scalar ships as a monorepo, so the feed interleaves three release lines: the API reference (1.6x), the API client (1.1.x) and the mock server (0.1x). The June run brought AsyncAPI rendering to parity with dedicated tooling, added UI localization for seven languages with RTL handling, gave the client a requestBuilt hook for request signing, and taught the mock server to serve AsyncAPI documents over WebSocket and SSE.

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.

Scalar's mock server learns event-driven APIs while the reference UI picks up localization

◆ Current state

Scalar ships as a monorepo, so the feed interleaves three release lines: the API reference (1.6x), the API client (1.1.x) and the mock server (0.1x). The June run brought AsyncAPI rendering to parity with dedicated tooling, added UI localization for seven languages with RTL handling, gave the client a requestBuilt hook for request signing, and taught the mock server to serve AsyncAPI documents over WebSocket and SSE.

◆ Where it's heading

AsyncAPI is the clear investment across all three packages — rendered in the reference, filterable in navigation, and now mockable as live event streams. The client and reference lines otherwise trend toward extension points and polish rather than new surface.

◆ Prediction

Expect AsyncAPI support to complete the loop by reaching the API client, so event-driven APIs can be exercised interactively the way REST endpoints already are.
