Pros and cons

Kagi

Pros

  • No advertising; revenue comes from subscriptions.
  • Site-level raise, lower and block controls let users tune results.
  • Lenses give quick topic-specific filtering such as Academic or Forums.
  • Ultimate bundles access to Claude, GPT and Gemini models in Assistant.
  • Public APIs and an MCP server support developer use.
  • Transparent funding history published by the company.

Cons

  • No permanent free tier: the trial is limited to 100 searches.
  • The $5 Starter plan caps searches at 300 per month, which users report running out of quickly.
  • Reviewers report that lens use and loading more results can count as extra searches.
  • Full AI model access requires the $25 Ultimate plan.

Opera Neon

Pros

  • Combines chat, browser actions, research and content creation in one browser rather than a separate extension.
  • Neon Do shows its plan and actions in real time and can be paused or taken over.
  • Wide model choice across OpenAI, Anthropic, Google, xAI and open-weight models on the Standard plan.
  • MCP connector and CLI let external agents such as Claude Code or n8n use a live browser session.
  • Credentials, passwords and card details are stated to stay on the device, and Opera says it does not train on user data.
  • Free VPN and ad blocker are included in the browser.

Cons

  • Full agentic features need the $19.90 per month Standard plan, higher than many AI add-ons.
  • Windows and macOS only; no Linux, iOS or Android version yet.
  • Neon Do uses cloud LLMs to plan, and page content is sent to Opera and OpenAI servers with 365-day retention.
  • Opera itself calls Neon an experimental agentic browser, so behaviour and plan limits may change.
