Spectrawl

Spectrawl

The unified web layer for AI agents. Search, browse, authenticate, and act on platforms — one package, self-hosted.

5,000 free searches/month via Gemini Grounded Search. Full page scraping, stealth browsing, 24 platform adapters.

What It Does

AI agents need to interact with the web — searching, browsing pages, logging into platforms, posting content. Today you wire together Playwright + a search API + cookie managers + platform-specific scripts. Spectrawl is one package that does all of it.

npm install spectrawl

How It Works

Spectrawl searches via Gemini Grounded Search (Google-quality results), scrapes the top pages for full content, and returns everything to your agent. Your agent's LLM reads the actual sources and forms its own answer — no pre-chewed summaries.

Quick Start

npm install spectrawl
export GEMINI_API_KEY=your-free-key  # Get one at aistudio.google.com

const { Spectrawl } = require('spectrawl')
const web = new Spectrawl()

// Deep search — returns sources for your agent/LLM to process
const result = await web.deepSearch('how to build an MCP server in Node.js')
console.log(result.sources)   // [{ title, url, content, score }]

// With AI summary (opt-in — uses extra Gemini call)
const withAnswer = await web.deepSearch('query', { summarize: true })
console.log(withAnswer.answer)  // AI-generated answer with [1] [2] citations

// Fast mode — snippets only, skip scraping
const fast = await web.deepSearch('query', { mode: 'fast' })

// Basic search — raw results
const basic = await web.search('query')

Why no summary by default? Your agent already has an LLM. If we summarize AND your agent summarizes, you're paying two LLMs for one answer. We return rich sources — your agent does the rest.

Spectrawl vs Tavily

Different tools for different needs.

Tavily is fast and simple — great for agents that need quick answers. Spectrawl returns richer data and does more (browse, auth, post) — but it's slower. Choose based on your use case.

Search

Default cascade: Gemini Grounded → Tavily → Brave

Gemini Grounded Search gives you Google-quality results through the Gemini API. Free tier: 5,000 grounded queries/month.

Deep Search Pipeline

Query → Gemini Grounded + DDG (parallel)
  → Merge & deduplicate (12-19 results)
  → Source quality ranking (boost GitHub/SO/Reddit, penalize SEO spam)
  → Parallel scraping (Jina → readability → Playwright fallback)
  → Returns sources to your agent (AI summary opt-in with summarize: true)

What you get without any keys

DDG-only search, raw results, no AI answer. Works from home IPs. Datacenter IPs get rate-limited by DDG — recommend at minimum a free Gemini key.

Browse

Stealth browsing with anti-detection. Three tiers (auto-detected):

1. playwright-extra + stealth plugin — default, works immediately
2. Camoufox binary — engine-level anti-fingerprint (npx spectrawl install-stealth)
3. Remote Camoufox — for existing deployments

const page = await web.browse('https://example.com')
console.log(page.content)       // extracted text/markdown
console.log(page.screenshot)    // PNG buffer (if requested)

Auto-fallback: if Jina and readability return too little content (<200 chars), Spectrawl renders the page with Playwright and extracts from the rendered DOM. Tavily can't do this — they fail on JS-heavy pages.

Auth

Persistent cookie storage (SQLite), multi-account management, automatic expiry detection.

// Add account
await web.auth.add('x', { account: '@myhandle', method: 'cookie', cookies })

// Check health
const accounts = await web.auth.getStatus()
// [{ platform: 'x', account: '@myhandle', status: 'valid', expiresAt: '...' }]

Cookie refresh cron fires cookie_expiring and cookie_expired events before accounts go stale.

Act — 24 Platform Adapters

Post to 24+ platforms with one API:

await web.act('github', 'create-issue', { repo: 'user/repo', title: 'Bug report', body: '...' })
await web.act('reddit', 'post', { subreddit: 'node', title: '...', text: '...' })
await web.act('devto', 'post', { title: '...', body: '...', tags: ['ai'] })
await web.act('huggingface', 'create-repo', { name: 'my-model', type: 'model' })

Live tested: GitHub ✅, Reddit ✅, Dev.to ✅, HuggingFace ✅, X (reads) ✅

Built-in rate limiting, content dedup (MD5, 24h window), and dead letter queue for retries.

Source Quality Ranking

Spectrawl ranks results by domain trust — something Tavily doesn't do:

• Boosted: GitHub, StackOverflow, HN, Reddit, MDN, arxiv, Wikipedia
• Penalized: SEO farms, thin content sites, tag/category pages
• Customizable: bring your own domain weights

const web = new Spectrawl({
  sourceRanker: {
    boost: ['github.com', 'news.ycombinator.com'],
    block: ['spamsite.com']
  }
})

HTTP Server

npx spectrawl serve --port 3900

POST /search   { "query": "...", "summarize": true }
POST /browse   { "url": "...", "screenshot": true }
POST /act      { "platform": "github", "action": "create-issue", ... }
GET  /status   — auth account health
GET  /health   — server health

MCP Server

Works with any MCP-compatible agent (Claude, Cursor, OpenClaw, LangChain):

npx spectrawl mcp

5 tools: web_search, web_browse, web_act, web_auth, web_status.

CLI

npx spectrawl init              # create spectrawl.json
npx spectrawl search "query"    # search from terminal
npx spectrawl status            # check auth health
npx spectrawl serve             # start HTTP server
npx spectrawl mcp               # start MCP server
npx spectrawl install-stealth   # download Camoufox browser
