Backlog users lack certain convenient features like effort aggregation, custom favicons, parent/child issue filtering in Gantt charts, and quick copy buttons for PR/issue info. This extension fills those gaps.

The extension installs as a Chrome extension. When the user navigates to a Backlog domain (backlog.com, backlog.jp, backlogtool.com), content scripts inject into the page and add UI enhancements (buttons, filters, icons) to the existing Backlog interface. The extension popup allows users to configure plugin settings. No separate login is required beyond the user's existing Backlog account session.

Target users: Nulab Backlog users / Software development teams using Backlog for project management / Project managers and developers who use Backlog's issue tracking, wiki, and Gantt features

The JavaScript files are heavily minified, making it difficult to trace all plugin logic in detail. However, the manifest, locale files, and store description provide sufficient evidence for the three decisions.
Could not verify if there are any server-side checks or API calls that might indicate paid features, as the extension appears to be purely client-side DOM manipulation.
The extension uses wxt (Web Extension Toolkit) for building, which is a development framework and not indicative of paid features.

Monetization

No paid features detected

The extension source code contains no references to payment platforms, subscription management, license keys, upgrade prompts, or paid feature gating. The keyword matches for 'pro' in the static analysis are false positives from React library references ('react-jsx-runtime.production.js') and CSS class names containing 'pro'. The extension appears to be a free utility for Backlog users. While the destination service (Nulab Backlog) may have its own paid plans, the extension itself does not gate features behind a paywall or call any billing APIs.

Login required: Yes
Reason: The extension is a content script that injects into *.backlog.com, *.backlog.jp, and *.backlogtool.com domains. These are Nulab Backlog web application domains. The extension's plugins (e.g., issue filtering, wiki enhancements, Gantt chart filters) operate on the Backlog UI and require the user to be logged into their Backlog account to function. The extension itself does not implement its own login mechanism; it relies on the destination service's authentication.
