개요
Nano Browser란?
Nano Browser(Nanobrowser)는 Chrome 확장 프로그램 형태로 실행되는 오픈소스 AI 웹 에이전트입니다. 여러 전문 에이전트를 사용해 브라우저에서 태스크를 계획, 탐색, 실행합니다.
Multi-agent system
A Planner agent breaks down tasks while Navigator agents interact with pages, letting workflows self-correct.
Bring your own API keys
Connect OpenAI, Anthropic, Gemini, Ollama, Groq, Cerebras, Llama, or any OpenAI-compatible provider.
Privacy-first, local execution
Credentials and session data stay in your browser, not on a remote automation cloud.
확장 프로그램의 한계
왜 Nano Browser 사용자는 대안을 찾는가
Nanobrowser는 개발자에게 훌륭하지만 Chrome 확장 프로그램 형태는 일상적인 파워 사용자에게 마찰을 만듭니다.
It is not a real browser
Extensions cannot redesign tabs, workspaces, or the omnibox. You still browse inside plain Chrome.
API keys and quotas to manage
You must bring, fund, and debug your own LLM keys before any agent can run.
No built-in workspace discipline
Without vertical tabs or project spaces, deep research sessions quickly become tab chaos.
Limited to Chromium browsers
If your workflow spans different environments, you are tied to Chrome or Edge.
왜 Tabbit인가
Nano Browser가 가리키는 AI 네이티브 브라우저
Tabbit delivers the same agentic promise—autonomous web research, form filling, and data aggregation—but as a full browser, not an add-on. That means the agent, the tabs, the workspaces, and the AI chat all share one surface.
You also skip the API-key setup. Tabbit gives you multi-model access out of the box, runs on macOS and Windows, and keeps every sensitive step behind an explicit approval.
- ●Full browser with built-in agentic AI
- ●Vertical tabs + project workspaces
- ●Multi-model AI without API key setup
- ●One-click import from Chrome, Edge, Safari
- ●Free download for macOS and Windows
얻는 것
확장 프로그램이 멈추는 곳에서 Tabbit가 나아가는 3가지 이유
Agent mode inside a real browser
Agents run in isolated tab groups, read pages, fill forms, and report back—without leaving the browser context.
Workspace-native tab design
Vertical sidebar, smart grouping, and project workspaces keep research sessions scannable at any depth.
Skills + omnibox context
Save prompts and scripts as reusable Skills. Type @ in the omnibox to reference tabs, screenshots, or files.
