In-depth safety analysis
Better Ruler requests the activeTab, scripting, and storage permissions. Together, these let it draw a measuring overlay on the current webpage when you click the extension, and save your settings like ruler colour or unit preference. This permission set is focused and expected for a ruler tool — it does not ask for broad host access or sensitive data, and only interacts with pages on your explicit command.
As a general browser extension that injects scripts into pages, the typical safety consideration is that a compromised or poorly intended update could alter what gets injected. Since the extension operates on activeTab only, the risk surface is limited to pages you deliberately measure. Standard caution applies: stay alert to unexpected permission changes, read recent reviews, and verify that the functionality stays consistent.
In our assessment, Maintenance & Ownership scores 100/100, showing the extension is actively maintained and not abandoned. The weakest dimension is Publisher & Identity (60/100), which simply reflects that the developer is an individual with little public identity verification. That is common for small extensions and does not signal a problem, but users who prioritise publisher transparency may prefer more clearly identified teams.

Who's Behind Better Ruler?
- Publisher paul
Public records identify the publisher, but no individual founders or a separate registered company are named — which is what holds the Publisher & Identity score back. Less public information about who operates an extension means less you can verify about their long-term accountability.
