What is Backlog?

Backlog ships steady Gantt and chart refinements, but the feed is mostly Nulab site furniture.

Only two entries in this window carry actual release content, and both are monthly digests: chart groups gaining a start/end date bar with issue counts and status breakdown on hover, personal charts dropping the parent-subtask relationship, an Android 3.0.1 redesign, Markdown in iOS custom-field text areas, plus quarterly-scale Gantt charts for Premium and Platinum plans and child-issue status filtering. The rest of the window is navigation, support links and marketing copy scraped from nulab.com — including rows that belong to sibling products Cacoo and Nulab Pass rather than to Backlog.

What is Leantime?

Leantime swaps role ranks for real permissions and syncs with your calendar app.

Leantime moved from 3.10 to 3.14 between October and 10 November. v3.14.0 replaces role-rank checks with specific permission checks across projects, timesheets, users, API keys, to-dos, milestones and sprints, and opens the calendar to plugins; a new CalDAV plugin syncs both ways with Nextcloud, Radicale and Apple Calendar. Earlier releases added mobile push, per-project modules, global search and self-updating plugins.

Backlog vs Leantime: editorial side-by-side

Backlog logo0.0

Backlog ships steady Gantt and chart refinements, but the feed is mostly Nulab site furniture.

◆ Current state

Only two entries in this window carry actual release content, and both are monthly digests: chart groups gaining a start/end date bar with issue counts and status breakdown on hover, personal charts dropping the parent-subtask relationship, an Android 3.0.1 redesign, Markdown in iOS custom-field text areas, plus quarterly-scale Gantt charts for Premium and Platinum plans and child-issue status filtering. The rest of the window is navigation, support links and marketing copy scraped from nulab.com — including rows that belong to sibling products Cacoo and Nulab Pass rather than to Backlog.

◆ Where it's heading

The real work is concentrated on planning views — Gantt scale, chart grouping, issue filtering — and on closing gaps between the web app and the mobile clients. Several changes are explicitly gated to Premium and Platinum plans, so view sophistication is being used as tier differentiation. Nothing here suggests a change of direction; it is a mature tracker refining how work is visualised.

◆ Prediction

Given the run of chart and Gantt scale work, the next planning-view change is likely another axis of aggregation or filtering rather than a new surface. The scraped entries make cadence unreliable, so any stronger call would not be grounded.

L5.0

Leantime swaps role ranks for real permissions and syncs with your calendar app.

◆ Current state

Leantime moved from 3.10 to 3.14 between October and 10 November. v3.14.0 replaces role-rank checks with specific permission checks across projects, timesheets, users, API keys, to-dos, milestones and sprints, and opens the calendar to plugins; a new CalDAV plugin syncs both ways with Nextcloud, Radicale and Apple Calendar. Earlier releases added mobile push, per-project modules, global search and self-updating plugins.

◆ Where it's heading

The release cadence is roughly one feature version every two weeks, split between finer access control and a plugin marketplace that carries more functionality. Core changes increasingly exist to give plugins stable hooks, as the calendar rework shows.

◆ Prediction

Expect more marketplace plugins built on the new calendar and permission hooks, and further permission work extending to the remaining modules.
