About

The UIKI AI assistant runs 100% offline, providing page summaries and accurate parental controls without data leaving your device. New in v11.1.0: World-first Transparent Telemetry, Green Web Alliance support, and Contributor Mode to earn benefits. Key features include built-in Neural Search, native ad blocker, military-grade password manager, and auto-translation. For productivity and gaming, it offers Game Mode, Stellar Mode (overlay), smart tab grouping, and intelligent resource usage (minimal CPU/RAM). Enjoy full customization (4 modes, news feeds), automatic local backups, and sandboxed security. Available in 24 languages, free forever, with no account required.

About

Kitesurf is an agent-first browser built specifically for AI agents and runs entirely on Cloudflare Workers instead of using Chromium. It is designed around what agents actually need: structured machine-readable content, scalable execution, low CPU and memory use, and safe interaction with untrusted web pages, rather than human-facing features such as tabs, themes, extensions, or pixel-perfect scrolling. Each page load is treated as untrusted input, every session starts fresh, and components are isolated with access only to the resources required for their function. Kitesurf uses native Rust compiled to WebAssembly where possible and is organized around an Engine, PageScript, and PageRenderer. The Engine exposes Chrome DevTools Protocol WebSocket and REST APIs and stores session state, while PageScript parses HTML and CSS and runs JavaScript and WebAssembly inside isolated Workers.

Pros & Cons from Real Users

Pros

  • Complete privacy, ai 100% offline, the only browser with verifiable public telemetry?? Congrats, guys! Amazing
  • Cronos is everything I wanted in a browser. It’s super fast. If you want a secure and fast experience, look no further. This is exactly what the web should feel like!
  • A next-level browser for gamers with a real wow factor — Stellar Mode. Faster. Smarter. Better. Instant
  • I like that it's different, it's something completely new compared to traditional browsers.

Cons

  • Just… Competitors can copy features and maybe too complex for average users
  • It’s still growing, so I’d love to see even more extensions added in the future, but it’s already amazing.
  • Stellar Mode – Optimized performance for gamers, delivering smoother browsing, faster response times, and reduced resource usage.
  • So far I haven't found anything I don't like, I still explore
