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 Productboard?

Productboard v2 adds exact-match text filters as the data model keeps widening.

Productboard's v2 API spent the summer closing v1 parity gaps, then in September made entity types an open, workspace-specific string. Since then the data model has kept widening: rich text accepts tables and checklists, relationships hold their own field values, and as of October 15 entity search supports exact-match filtering on text fields.

Backlog vs Productboard: 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.

P6.3

Productboard v2 adds exact-match text filters as the data model keeps widening.

◆ Current state

Productboard's v2 API spent the summer closing v1 parity gaps, then in September made entity types an open, workspace-specific string. Since then the data model has kept widening: rich text accepts tables and checklists, relationships hold their own field values, and as of October 15 entity search supports exact-match filtering on text fields.

◆ Where it's heading

With parity mostly done, v2 is extending the data model and making it queryable. Workspace-defined entity types and relationship fields push schema decisions into each workspace's configuration, and filter operators like eq let integrations match records precisely instead of scanning with contains.

◆ Prediction

Expect filtering and search to reach relationship fields next, following the pattern of new data shapes gaining query operators a few weeks later. Whether the beta customer score endpoint leaves beta isn't signalled by the entries.
