Peekier

Peekier is a privacy-focused search engine with thumbnails of the sites you visit before you click on them. I like the concept. I think the back-end uses Bing results, which is different from Google's. However:

1. You can change options to limit the adult content.
2. You cannot search using advanced search options without typing them into the search (for example, typing cloud images or 2019 free email providers).
3. It is very difficult to see if an outdated result appears. Old links that no longer work, though, show as blank.
