Backlog vs Tability
A side-by-side editorial comparison of Backlog and Tability — release velocity, themes, recent moves, and the top alternatives to consider.
Backlog vs Tability: 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 Tability?
Tability is handing OKR upkeep to agents, with the manager kept in the approval seat.
Tability shipped a single dated train on August 6 covering agent delegation, an AI spreadsheet importer, wider AI Mode context, and a Skills Library for Claude and ChatGPT. Underneath that sits the KPI module introduced in mid-July, which split business-as-usual metrics away from OKRs and gave them their own permissions, views, and import path. The product now has two tracked object types and is layering AI onto the labor of maintaining both.
Backlog vs Tability: editorial side-by-side
Backlog
0.0PM
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.
Tability
7.5PM
Tability is handing OKR upkeep to agents, with the manager kept in the approval seat.
◆ Current state
Tability shipped a single dated train on August 6 covering agent delegation, an AI spreadsheet importer, wider AI Mode context, and a Skills Library for Claude and ChatGPT. Underneath that sits the KPI module introduced in mid-July, which split business-as-usual metrics away from OKRs and gave them their own permissions, views, and import path. The product now has two tracked object types and is layering AI onto the labor of maintaining both.
◆ Where it's heading
Every recent addition attacks the same weakness in goal-tracking tools: the data goes stale because updating it is nobody's job. Tability's answer is to let agents do the gathering and drafting while routing proposals, decisions, access requests, and blockers back to a human before anything commits. The Skills Library and MCP integration point outward — the company appears content for the actual reasoning to happen in Claude or ChatGPT while Tability holds the structured record.
◆ Prediction
The delegation flow is the piece with room to run; expect agents to move from preparing work to posting check-ins and flagging at-risk goals on a schedule, with the KPI module as the data source. Whether the Skills Library grows or gets absorbed into the agent flow is the open question the entries do not settle.
