Features Tooltivity's expert score for the 'Features' aspect of each extension. | 8.5 Diigo offers basic features for a highlighter and bookmarking tool. It works well and we were able to highlight most websites and they were recreated when revisiting them. The highlighter popup makes it easy to highlight text offering 4 colors. It looks like this: ![]() We would have wished to have more color options. Also, note-taking and the tagging functionality are working, but its design does not look appealing. ![]() The dashboard where your highlights are stored works well and gives you an overview of all your highlights. ![]() Winner in this category | 8.5 Nowadays, websites request data through third parties. The local CDN emulation offered by Decentraleyes is a unique and effective feature that blocker competitors currently lack. This means that the same locally stored data is always sent directly to the websites before they can even request relevant private data. ![]()
Another advantage of the extension is that the code is completely open source and can be found on GitLab. This ensures transparency and trust. Winner in this category |
Performance Tooltivity's expert score for the 'Performance' aspect of each extension. | 8.0 Diigo performs well in terms of highlighting and syncing across devices. The fact that highlights are always synchronized can cause some loading delays. It's not as fast as other highlighters that use an offline-first approach, but it works reasonably well. However, the unreliable link creation feature and the simple sidebar outliner design need improvement. | 9.3 The extension offers a noticeable improvement in page load times. We did not find any problems in our tests, but according to user reviews, there are occasional compatibility problems with certain websites. However, according to Decentraleyes, these are constantly being fixed by updates. Winner in this category |
Design Tooltivity's expert score for the 'Design' aspect of each extension. | 7.0 The design fulfills its functionality. The design of Diigo is outdated and could use a modern refresh. The lack of a nice overview of all your highlights on the page itself means you have to open the dashboard on diigo.com instead. The dashboard on diigo.com is okay, but other highlighters like Web Highlights have a much nicer user interface. | 9.5 The design is intuitive and simple. This also includes the settings menu. Winner in this category |
Value for Money Tooltivity's expert score for the 'Value for Money' aspect of each extension. | 8.0 The free version of Diigo offers basic features and is fine for most users. The paid plans are reasonably priced and similar to other highlighters. However, we think other highlighters offer more value for the same price. | 9.5 The extension is completely free to use with optional donations. The price-performance ratio is therefore perfect, as functions that are not offered by other providers are made available here free of charge. Only the lack of further functions in the area of ad blocking results in deductions. Winner in this category |
Ease of Use Tooltivity's expert score for the 'Ease of Use' aspect of each extension. | 7.8 Diigo is fairly easy to use, but the sidebar outliner takes some time to get used to. You can't see all your highlights on the page itself, so you have to go to the dashboard on diigo.com. We wish there was a sidebar to quickly access all our highlighted pages, like in the Web Highlights extension. | 9.9 The extension is characterized by its user-friendliness. Installation is very simple and you have the option of testing the function immediately on the website. When you open the website https://decentraleyes.org/test/, you are shown whether the function works and an example of what it looks like in the icon when data is blocked. ![]() The settings are also very well described so that even beginners should have no problems here. Advanced users can also read the complete documentation or the code on GitLab. ![]() Winner in this category |
Security & Privacy Tooltivity's expert score for the 'Security & Privacy' aspect of each extension. | 7.5 Diigo takes reasonable steps to protect user data. However, since you need an account and your data is stored in their database, absolute protection can't be guaranteed. We think a highlighter should work without needing to sign up, but this feature is missing in Diigo. | 9.2 The extension offers strong features in the area of data protection, so it goes without saying that it scores well in this area. The open-source code allows anyone to review the extension in detail. Only the lack of a proper privacy policy detracts from this for beginners, who can do little with the code. There is a privacy policy that states in one sentence that no data is collected. However, this should be a little more detailed. Winner in this category |
Conclusion A summary of our findings and final thoughts for each extension. | Diigo is a handy tool for collecting stuff from the web, like bookmarks, highlights, and notes.
| Decentraleyes is a valuable tool for anyone who wants more privacy and faster browsing. With local CDN emulation, Decentraleyes has features that bring both security and performance benefits. While it currently excels in this one area, you need to be aware that websites also make adjustments and it won't always work 100% of the time, especially without further updates. |
