完整自主瀏覽

以自然語言驅動的 AI 瀏覽器自動化。告訴它要做什麼，看著它替你瀏覽。

為現代 Web 而生

由領先的 AI 模型驅動，提供智慧瀏覽器自動化所需的一切。

Direct API Execution

Beyond clicking. FSB can call an app's own authenticated API through your logged-in session. Faster and more reliable than DOM automation, with DOM as the automatic fallback. Inspired by OpenTabs.

60 Browser Actions

Click, type, scroll, drag-and-drop, canvas drawing, CDP mouse control, multi-tab management, and more. 53 DOM actions plus 7 through the Chrome DevTools Protocol.

Reactive Triggers

Watch any element and get notified the instant a value changes, crosses a threshold, or matches a pattern.

智慧 DOM 分析

增量 DOM 差分、多策略選擇器以及元素識別，讓自動化更可靠。

Autopilot

Rebuilt on the Lattice SDK, long runs survive Chrome's MV3 shutdowns and finish. Up to 64 concurrent tabs, plus real file uploads from disk.

視覺化反饋

Glow borders, pulsing element highlights, and a floating progress overlay show exactly what FSB is doing.

站點情報

130+ built-in site guides across 17 categories, from commerce to coding.

MCP 整合

Use FSB as an MCP server from Claude Code, Codex, Cursor, OpenClaw, or any MCP client. 66 tools, with browser automation straight from your IDE.

遠端控制檯

Monitor and control FSB from any device. QR-code pairing, a live DOM preview powered by PhantomStream, now with media mirroring, and real-time task execution.

記憶與學習

FSB 跨站點記住導航模式。語義、情景、過程性三類記憶讓自動化隨著時間越來越聰明。

比它們都強。無需視覺。

Project Mariner、Claude Computer Use、OpenAI Operator、OpenClaw。它們都依靠視覺理解頁面。FSB 讀取真實的 DOM。無需視覺，更快、更便宜、更準確。

與它們協同工作

FSB 不只是競爭，更是互補。透過它的 MCP 伺服器，Claude Code、Codex、Cursor、Windsurf 以及任何相容 MCP 的智慧體都能把 FSB 用作瀏覽器自動化層。把任意 AI 的智慧與 FSB DOM 引擎的精度結合在一起。

Native API handlers

It clicks when it must. It calls APIs when it can.

FSB no longer has to drive a UI for everything. For supported apps it talks straight to the app's own authenticated API through your logged-in session, far faster and more reliable than DOM automation, and falls back to clicking automatically when no API exists.
