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 makes entity types per-workspace, breaking fixed-enum clients in favor of extensibility

Productboard's v2 API has been on a steady expansion path through summer: fulltext search for notes, company source metadata, team and tag filtering, custom field presence filters. These entries fill v1 parity gaps. The September 22 EntityType change is the first real breaking move — shifting from a fixed enum to an open string that varies by workspace. Clients that assumed a fixed set of entity types now need to query the workspace's entity configuration to get the authoritative list.

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 makes entity types per-workspace, breaking fixed-enum clients in favor of extensibility

◆ Current state

Productboard's v2 API has been on a steady expansion path through summer: fulltext search for notes, company source metadata, team and tag filtering, custom field presence filters. These entries fill v1 parity gaps. The September 22 EntityType change is the first real breaking move — shifting from a fixed enum to an open string that varies by workspace. Clients that assumed a fixed set of entity types now need to query the workspace's entity configuration to get the authoritative list.

◆ Where it's heading

The EntityType shift is the foundation for workspace-specific schema customization in v2. The pattern across the June–September entries is: close v1 parity gaps, then add extensibility hooks. The beta customer score endpoint signals that Productboard is adding analytics surfaces on top of the data model, not just read/write operations.

◆ Prediction

The beta customer score endpoint will likely reach GA in a subsequent release as usage accumulates from enabled workspaces. Dynamic entity types will likely unlock workspace-specific filtering and field configuration in later API releases.
