CRW Web Scraper
io.github.fastcrw由 GitHub 帳號 fastcrw 發布v0.44.0更新於 Nov 12, 2026
Open-source web scraper for AI agents with scrape, crawl, and map tools
概覽
面向 AI 代理的開源網頁擷取工具,透過擷取、爬取、站點對應、搜尋與擷取欄位,把網址轉成乾淨的 Markdown 或結構化 JSON。
- 可以做什麼
- 將單一網址擷取為 Markdown、HTML、連結、截圖或依 schema 輸出的 JSON
- 在限定範圍內爬取站點並收集其頁面
- 對應站點以找出網址,而不必擷取每個頁面
- 搜尋網路,並可選擇擷取指定結果
- 從一個或多個網址擷取結構化欄位
- 適用情境
- 適合需要把網頁內容或結構化資料帶入任務的情境,例如掌握站點有哪些頁面,或執行網路搜尋並擷取結果。可用於本機自架,也可使用託管雲端 API。
- 執行需求
- 以本機程序方式執行於 macOS 與 Linux(Intel 與 ARM),可安裝為小型 Rust 二進位檔,或透過 npm 的 MCP 安裝器安裝。本機模式不需帳號;託管雲端模式需要 CRW_API_KEY,並存放在本機設定檔中。需要網路連線。
安裝
在 SourceWeft 中
- 開啟 儀表板中的 CRW Web Scraper,將其新增到工作區。
- 為需要使用其工具的對話啟用該服務。
Desktop only,透過 STDIO。 STDIO 服務會啟動本機處理程序,因此需要 SourceWeft 桌面主機。

One-command install
Runs local and free, no account needed. To use the Cloud, paste your key into the same command and it installs the binary, connects the key, and registers the MCP server with the AI coding tools you already have:
Claude Code, Cursor, Codex, Gemini CLI, OpenCode and Windsurf are picked up
automatically when they are already set up; nothing else is touched, and your
key stays in ~/.config/crw/config.toml rather than being copied into each
tool. Add CRW_NO_AGENTS=1 to skip that step, or run crw setup on its own to
choose interactively.
1000 free credits, no credit card. Managed proxies, JS rendering and search, with nothing to run or keep up to date. Get my free key →

What it does
Why fastCRW
On Firecrawl's own public 1,000-URL dataset, fastCRW recovered more truth than Crawl4AI and Firecrawl, matched the fastest median latency, and idled at ~14 MB RAM.
Methodology, full numbers, and how to reproduce it
On a different benchmark entirely, answer accuracy rather than scrape recall, fastCRW answers 90.0% of the 600 AA-Omniscience questions correctly. Every product listed on the Artificial Analysis Search Index sits below it.

MCP for AI agents
Installs the CRW skill and MCP server in your detected AI tools. crw setup can
also do this step, so either path is enough.
