Backlog vs Sugar Calendar
A side-by-side editorial comparison of Backlog and Sugar Calendar — release velocity, themes, recent moves, and the top alternatives to consider.
Backlog vs Sugar Calendar: at a glance
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 Sugar Calendar?
The changelog turned into a how-to blog — capability news now arrives disguised as tutorials.
Sugar Calendar has stopped publishing version posts. The last three entries read as tutorials — building event pages in Elementor, setting tiered ticket prices for a single event, attaching a Zoom meeting without copying links by hand — where earlier entries were explicit 3.x release announcements. The bodies are truncated teasers, so what shipped versus what was always possible is not stated outright.

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.

◆ Current state
Sugar Calendar has stopped publishing version posts.

The bodies are truncated teasers, so what shipped versus what was always possible is not stated outright.
◆ Where it's heading
Two things are moving at once. The product is filling in the integration surface an events plugin needs — page builder, video conferencing, flexible ticket pricing — and the communication has shifted from version-led to problem-led. That makes the feed better for prospective buyers and worse as a changelog: the release boundary is now invisible.
◆ Prediction
Expect more problem-framed posts covering individual capabilities rather than a numbered 3.8 announcement. These entries do not say whether the Elementor and Zoom work ships as core or as paid add-ons, so the packaging is unclear.
