Clarizen vs Leantime
A side-by-side editorial comparison of Clarizen and Leantime — release velocity, themes, recent moves, and the top alternatives to consider.
Clarizen vs Leantime: at a glance
What is Clarizen?
Planview AdaptiveWork (formerly Clarizen) shows version timeline 2026.02→2026.03, but the visible feed is mostly customer success portal navigation.
The captured Planview AdaptiveWork feed is dominated by customer success portal cards — Connect 2026 conference promotion, UX Research Lab participation, system status links, and the Success Accelerator program. The one release-relevant page is the AdaptiveWork Release Notes index, which shows version timeline markers for 2026.02 (current) and 2026.03 (upcoming 'NEXT RELEASE') but the crawler is capturing the index rather than the per-release detail pages.
What is Leantime?
Leantime lands a major architecture rebuild, then spends a week stabilizing its API auth
Leantime is working through the aftermath of 3.9.0, a large architectural release that introduced a native permission engine, a JSON-RPC API layer, consolidated 16 canvas variants into a unified Blueprints domain, and added mobile push notifications. The subsequent 3.9.1-3.9.5 train is dominated by fixing Bearer/token authentication regressions that release introduced.

Clarizen
0.0PM
Planview AdaptiveWork (formerly Clarizen) shows version timeline 2026.02→2026.03, but the visible feed is mostly customer success portal navigation.
◆ Current state
The captured Planview AdaptiveWork feed is dominated by customer success portal cards — Connect 2026 conference promotion, UX Research Lab participation, system status links, and the Success Accelerator program. The one release-relevant page is the AdaptiveWork Release Notes index, which shows version timeline markers for 2026.02 (current) and 2026.03 (upcoming 'NEXT RELEASE') but the crawler is capturing the index rather than the per-release detail pages.
◆ Where it's heading
Without substantive release content visible, product trajectory isn't observable from this feed. The continued AdaptiveWork branding reflects Planview's post-Clarizen-acquisition consolidation. Connect 2026 promotion suggests an upcoming customer event in late spring or summer.
◆ Prediction
Confident predictions aren't possible from this slice. A different ingestion target (per-version pages under success.planview.com/Planview_AdaptiveWork/00_AdaptiveWork_Release_Notes/...) would surface actual release content and let trajectory and prediction become real.
Leantime
6.3PM
Leantime lands a major architecture rebuild, then spends a week stabilizing its API auth
◆ Current state
Leantime is working through the aftermath of 3.9.0, a large architectural release that introduced a native permission engine, a JSON-RPC API layer, consolidated 16 canvas variants into a unified Blueprints domain, and added mobile push notifications. The subsequent 3.9.1-3.9.5 train is dominated by fixing Bearer/token authentication regressions that release introduced.
◆ Where it's heading
The open-source PM tool is modernizing its foundation (thin controllers, typed exceptions, fail-closed authorization, Blade migration) to support a mobile app and third-party integrations. The near-term cost is a visible bugfix tail as token-based auth gets hardened path by path.
◆ Prediction
Expect the patch cadence to settle once Bearer-auth coverage stabilizes, with mobile endpoints and the JSON-RPC surface becoming the focus, given the mobile API work threaded through these releases.
