Kitsu vs Leantime

Kitsu vs Leantime: at a glance
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 Leantime?
Leantime is stabilizing its big 3.9 rewrite while extending cross-project planning and a mobile API
Leantime is deep in a modernization cycle. The 3.9.0 release rebuilt the app around a native, fail-closed permission engine, a JSON-RPC API, and a consolidated Blueprints domain; the releases since then mostly stabilize that foundation. Recent point releases fix regressions (repeated Bearer/PAT auth fixes) while adding cross-project program views and a mobile app backend.

Kitsu
2.5PM
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.
Leantime
6.3PM
Leantime is stabilizing its big 3.9 rewrite while extending cross-project planning and a mobile API
◆ Current state
Leantime is deep in a modernization cycle. The 3.9.0 release rebuilt the app around a native, fail-closed permission engine, a JSON-RPC API, and a consolidated Blueprints domain; the releases since then mostly stabilize that foundation. Recent point releases fix regressions (repeated Bearer/PAT auth fixes) while adding cross-project program views and a mobile app backend.
◆ Where it's heading
The work is consolidation over expansion: hardening the new auth/permission and API layers, closing security IDORs domain by domain, and building the surface a mobile app and program-level planning need. The steady stream of small patch releases reflects shaking out regressions from the 3.9.0 refactor rather than opening new product directions.
◆ Prediction
Expect continued point releases fixing regressions from the permission-engine and JSON-RPC migration, plus buildout of the Leantime Mobile app now that its Bearer-authenticated backend API is landing.
