Prices seem high... Features, seem nice (but not crazy):

• "Boosting" and blocking domains: basically permanent filters.
• "Lenses" - Similar to SearXNG's different tabs, but more like a profile style system.
• Bangs are the same as in SearXNG, and I think you can do the same, or similar, thing in Firefox.
• Custom CSS is cool and all but you can get that with a browser add-on (like Stylus).
• Their "Comprehensive result filtering" seems that same as every other browser
• They have Vim-ish keybinds, which SearXNG and DDG have.
• "Widgets" - Seems like Google's quick answers, user created ones are cool I guess.
• The "crystal orb" - Allows you to determine the "quality" of sites, and also open them in the Wayback Machine or adjust that boosting/blocking level.

Additionally, it seems that they don't have seem to have any external audits or releasing of code (correct me if I'm wrong). Additional they have a web browser, that's only for Apple's ecosystem. Overall, you pay for no-ads, I feel like for this feature set you could just use DuckDuckGo with advertisements off, or the HTML version (which doesn't include JavaScript either). I'm kinda skeptical about it, but if it ends up taking off I'll be happy there will be another alternative to Google.

This actually looks very cool, so many new backup solutions to try after this thread. 🥲
