What is Kitsu?

Kitsu is turning its studio pipeline tool into a client-facing review platform.

Kitsu, the open-source animation and VFX production tracker, is investing heavily in the review loop: onion skinning and shape annotations, an annotation eraser, public playlist links that let external reviewers comment without accounts, and client-visible comment toggles. In parallel it added OpenID Connect for studio SSO and production-setup tooling (project templates, retake-count and cross-task-type filters).

What is Sugar Calendar?

Events can finally ask attendees a question at the moment they sign up.

Registration Forms arrive as a tab on the event itself: a small builder with five field types — short text, long text, multiple choice, checkboxes and dropdown — each markable as required, asked at ticket checkout or on the RSVP form, with the answer landing on the attendee's record beside their name and ticket. The post is explicit that this collapses two separate requests, custom fields on checkout and custom fields on RSVP, into one feature. It follows a run of releases that added attendee email, Elementor page design, per-event ticket pricing and Zoom links.

Kitsu vs Sugar Calendar: editorial side-by-side

K2.5

Kitsu is turning its studio pipeline tool into a client-facing review platform.

◆ Current state

Kitsu, the open-source animation and VFX production tracker, is investing heavily in the review loop: onion skinning and shape annotations, an annotation eraser, public playlist links that let external reviewers comment without accounts, and client-visible comment toggles. In parallel it added OpenID Connect for studio SSO and production-setup tooling (project templates, retake-count and cross-task-type filters).

◆ Where it's heading

The clear direction is external collaboration — pulling clients, supervisors, and vendors into Kitsu's review player rather than exporting frames elsewhere. Enterprise auth (OIDC) and richer annotation tools reinforce a move from internal tracker toward a shared review-and-approval hub.

◆ Prediction

Expect the guest-review surface to deepen — more annotation fidelity and approval-workflow controls — and further identity/permissions work following OIDC. The cadence points to continued review-platform build-out.

S5.0

Events can finally ask attendees a question at the moment they sign up.

◆ Current state

Registration Forms arrive as a tab on the event itself: a small builder with five field types — short text, long text, multiple choice, checkboxes and dropdown — each markable as required, asked at ticket checkout or on the RSVP form, with the answer landing on the attendee's record beside their name and ticket. The post is explicit that this collapses two separate requests, custom fields on checkout and custom fields on RSVP, into one feature. It follows a run of releases that added attendee email, Elementor page design, per-event ticket pricing and Zoom links.

◆ Where it's heading

Every release this quarter has removed one thing an organiser previously did outside the plugin — the follow-up email, the page builder, the pricing spreadsheet, the Zoom link, and now the post-signup questionnaire and the spreadsheet of answers that went stale on the first cancellation. The pattern is consistent enough to read as a deliberate sweep of the manual work around an event rather than a feature roadmap. Each arrives as a how-to titled post rather than a release note.

◆ Prediction

Answers now sit on the attendee record, so the next obvious step is doing something with them in bulk — filtering or exporting attendees by response, or segmenting the follow-up email by answer. The post stops at collection.
