Productboard vs Leantime: at a glance
What is Productboard?
Productboard's v2 API becomes the only path as v1 heads for a July sunset
Productboard's developer surface is consolidating on the v2 public API, which went GA in April and made v1 a deprecated path with a July 8, 2026 sunset. Recent work is steady, additive refinement of v2's query model: new filters for note type, metadata source, and custom fields, plus reference docs for individual objects. The cadence is high, but each change is narrow.
What is Leantime?
Leantime hardens its new permission engine through a rapid-fire auth patch cycle.
Leantime just shipped 3.9.0, a ground-up permission engine that replaced ad-hoc role checks with centralized, fail-closed authorization across every domain, landing alongside a JSON-RPC API layer and mobile push tokens. The 3.9.1 through 3.9.4 point releases that followed are almost entirely auth stabilization: Bearer and personal-access-token authentication broke under the new Sanctum guard and took four patches to fully settle. The project is mid-transition from a legacy PHP codebase to a modern Laravel, Blade, and JSON-RPC stack.
Productboard vs Leantime: editorial side-by-side
Productboard's v2 API becomes the only path as v1 heads for a July sunset
◆ Current state
Productboard's developer surface is consolidating on the v2 public API, which went GA in April and made v1 a deprecated path with a July 8, 2026 sunset. Recent work is steady, additive refinement of v2's query model: new filters for note type, metadata source, and custom fields, plus reference docs for individual objects. The cadence is high, but each change is narrow.
◆ Where it's heading
The arc is a methodical v2 build-out: restructure the search and filter format once, then layer on filterable dimensions release by release. Breaking changes are being front-loaded ahead of the v1 sunset, after which the API should settle into purely additive growth. Reference documentation is being filled in alongside, signalling a push to get integrators onto v2 well before July.
◆ Prediction
Expect more filter and field-level query parameters on the v2 search endpoints, plus a final round of v1 migration notices as the July 8 sunset nears.
Leantime
6.3PM
Leantime hardens its new permission engine through a rapid-fire auth patch cycle.
◆ Current state
Leantime just shipped 3.9.0, a ground-up permission engine that replaced ad-hoc role checks with centralized, fail-closed authorization across every domain, landing alongside a JSON-RPC API layer and mobile push tokens. The 3.9.1 through 3.9.4 point releases that followed are almost entirely auth stabilization: Bearer and personal-access-token authentication broke under the new Sanctum guard and took four patches to fully settle. The project is mid-transition from a legacy PHP codebase to a modern Laravel, Blade, and JSON-RPC stack.
◆ Where it's heading
The direction is a comprehensive backend re-architecture, with the permission engine, JSON-RPC API, completed Blade template unification, and experimental Postgres support all converging on a cleaner, API-first core. The recent burst of Bearer-auth fixes shows the team paying down the regressions the permission-engine rollout introduced rather than adding new surface. Mobile is the next frontier: the 3.8.0 TestFlight API groundwork and 3.9.0 push tokens point to a native app nearing release.
◆ Prediction
Expect the auth-fix cadence to slow as the Bearer regressions settle, with attention shifting toward the mobile app's public launch and broader JSON-RPC endpoint coverage.
