Kryfto

The Production-Grade Browser Data Collection Runtime

Self-host your own headless browser fleet. Connect it instantly to AI agents, IDEs, and workflow engines via OpenAPI and MCP.

✨ Core Features

Kryfto is a comprehensive framework for automated data extraction, web crawling, and browser session execution.

🤖 AI Agent Ready: Ships with a built-in Model Context Protocol (MCP) server exposing 42+ tools. Instantly give Claude, Cursor, or Codex the ability to search, browse, extract, fact-check, run continuous research agents, and benchmark search quality on the live web.
🕵️‍♂️ Advanced Stealth & Anti-Bot Engine: Unified anti-bot layer with 12 rotated modern User-Agents (Chrome 130–133, Edge 131/133), per-browser Sec-Ch-Ua client hints, Sec-Fetch-* headers, Chromium-only Accept strings, engine-appropriate Referer headers, per-engine request spacing delays, canvas fingerprint randomization, WebGL vendor/renderer spoofing, navigator.platform matching, hardwareConcurrency randomization, WebRTC IP leak prevention, and an RFC 6265-compliant in-memory cookie jar with 30min TTL. New in v3.5.1: Consistent cross-signal fingerprints (UA matched to platform, screen, WebGL, fonts, and audio), 20-point browser evasion suite, humanized browser interactions (Bezier curve mouse movements with micro-overshoots, realistic typing with typos, smooth scrolling), per-domain browser session pool with 30min TTL, and browser-based CAPTCHA solving for Cloudflare Turnstile, reCAPTCHA v2, hCaptcha, and Datadome — all without external paid APIs. reCAPTCHA image grids are classified locally via CLIP vision (clip-vit-large-patch14), and audio challenges are transcribed locally via Whisper, both using @xenova/transformers.
🛡️ Zero Trace Privacy: Execute purely in-memory HTTP extractions wrapping our bot-evasion without persisting any telemetry or artifacts to the Postgres database.
⚙️ Workflow Engine Native: Fully documented OpenAPI spec makes it trivial to drop into n8n, Zapier, Make, or custom Python/TypeScript pipelines.
🖥️ Admin Dashboard: Built-in React admin UI (port 3001) for managing tokens, projects, jobs, crawls, audit logs, and per-role rate limits. Includes an interactive API Playground for testing any endpoint live and an Examples page with ready-to-use cURL commands. Dark-themed SPA served as a separate nginx container.
☁️ Enterprise Infrastructure: Backed by Postgres for persistence, Redis + BullMQ for reliable concurrent job queuing, and MinIO/S3 for long-term artifact storage.
📊 SLO Dashboard & Eval Suite: Built-in reliability monitoring with per-tool success rates, latency percentiles (p50/p95/p99), deterministic request replay, and a 10-query benchmark suite for nightly regression testing.
🔄 Continuous Research Agent: Deploy autonomous background research loops that search, monitor, diff pages, and fire webhook alerts — all from a single MCP tool call.

🚀 Quickstart (Self-Hosted)

Get Kryfto running locally in seconds using Docker Compose.

# Option 1: Auto-generate a secure .env with random tokens & passwords
node scripts/generate-env.mjs -o .env

# Option 2: Or copy the example and fill in values manually
cp .env.example .env

# Spin up the entire infrastructure (API, Dashboard, Worker, Postgres, Redis, Minio S3)
docker compose up -d --build

# Verify health
curl -H "Authorization: Bearer $KRYFTO_API_TOKEN" http://localhost:8080/v1/healthz

The Admin Dashboard is available at http://localhost:3001/dashboard/ — log in with your admin API token to manage tokens, projects, jobs, crawls, audit logs, and rate limits.

Once running, you can immediately dispatch extraction jobs to the headless worker fleet:

curl -X POST http://localhost:8080/v1/jobs \
  -H "Authorization: Bearer $KRYFTO_API_TOKEN" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: demo-example-1" \
  -d '{"url":"https://example.com"}'

Reading Extracted Data

After the job succeeds, retrieve the extracted Markdown or HTML artifact:

curl -H "Authorization: Bearer $KRYFTO_API_TOKEN" \
  http://localhost:8080/v1/jobs/<jobId>/artifacts

Running a Federated Search

Find up-to-date information across DuckDuckGo, Brave, and Google natively:

curl -X POST http://localhost:8080/v1/search \
  -H "Authorization: Bearer $KRYFTO_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"query":"playwright testing", "limit":5, "officialOnly":true}'

🧩 Ecosystem Integrations

Kryfto isn't just an API—it's designed to act as the web-browsing "motor cortex" for your existing tools.

1. 🤖 Claude Code, Cursor, & Codex (MCP)

You can directly attach Kryfto to your AI assistant using the bundled Model Context Protocol (MCP) server.

🪄 Auto-Generate Configuration

The easiest way to get your IDE connected is to run the interactive setup wizard. It will auto-detect your API token and absolute path:

node scripts/setup-mcp.mjs

Select your client (Claude, Cursor, Codex, RooCode) and copy the generated JSON/TOML into your config file.

Manual Configuration

Claude Code / Cursor — Add to claude_desktop_config.json:

{
  "mcpServers": {
    "kryfto": {
      "command": "node",
      "args": ["/absolute/path/to/kryfto/packages/mcp-server/dist/index.js"],
      "env": {
        "API_BASE_URL": "http://localhost:8080",
        "API_TOKEN": "<your-token>"
      }
    }
  }
}

OpenAI Codex — Add to .codex/config.toml (per-project) or ~/.codex/config.toml (global):

[mcp_servers.kryfto]
command = "node"
args = ["/absolute/path/to/kryfto/packages/mcp-server/dist/index.js"]

[mcp_servers.kryfto.env]
API_BASE_URL = "http://localhost:8080"
API_TOKEN = "<your-token>"

Remote VPS configuration (claude_desktop_config.json / Cursor MCP Menu):

⚠️ SSH Keys Required: The MCP tunnel relies on stdio and cannot accept manual passwords. You must set up SSH Key authentication from your local machine to your VPS.

macOS/Linux:

ssh-keygen -t ed25519 -C "your_email@example.com"
ssh-copy-id user@your-vps-ip

Windows (PowerShell):

ssh-keygen -t ed25519 -C "your_email@example.com"
$Key = Get-Content "$env:USERPROFILE\.ssh\id_ed25519.pub"
ssh user@your-vps-ip "mkdir -p ~/.ssh && echo '$Key' >> ~/.ssh/authorized_keys"

Once ssh user@your-vps-ip logs you in instantly without a password, paste this config:

{
  "mcpServers": {
    "kryfto-remote": {
      "command": "ssh",
      "args": [
        "user@your-vps-ip",
        "API_BASE_URL=http://localhost:8080",
        "API_TOKEN=<your-token>",
        "node",
        "/absolute/path/on/vps/to/kryfto/packages/mcp-server/dist/index.js"
      ]
    }
  }
}

🏆 Kryfto vs. Built-in Agent Browsers

Why install Kryfto when Claude and Cursor have built-in web search? Because Kryfto is engineered specifically for evidence-based deterministic scraping rather than noisy LLM-summarized search.

Kryfto MCP vs Built-in Browser Benchmark

Real-world benchmark (Query: latest Next.js 15 features):

Built-in Browser: Returns a mix of non-official blogs (e.g., nextjs15.com), video results, and unstructured snippets. Fails to consistently identify the newest minor release.
Kryfto MCP: Extracts the semantic release version (15.5) from the URL, automatically ranks the official nextjs.org blog at Rank #1, and extracts the raw Markdown documentation structure (headings, code blocks, publish date) in a single deterministic pass.

"For this specific task and latest run, I prefer MCP. Reason: it returned the official nextjs.org 15.5 page first and gave structured output (published_at, sections, extracted markdown) in one step. - AI Assistant Verdict"

2. ⚡ n8n & Workflow Automation (Deep Dive)

Kryfto exposes a fully typed /v1 REST API complete with an OpenAPI specification, making it the perfect engine for visual automation tools like n8n, Make, or Zapier.

Instead of paying for expensive API credits on premium scraping platforms, you can use n8n's native HTTP Request node to trigger Kryfto's headless browsers.

How to build an n8n Web Scraping Pipeline:

Trigger: Set up a Schedule Trigger (e.g., run every morning at 8 AM).

Action (Kryfto): Add an HTTP Request node pointing to your Kryfto instance:

Method: POST
URL: http://your-vps-ip:8080/v1/jobs
Headers: Authorization: Bearer <your-token>

Body (Extraction Job):

{
  "url": "https://news.ycombinator.com",
  "options": {
    "browserEngine": "chromium"
  },
  "extract": {
    "mode": "selectors",
    "selectors": {
      "topStories": ".titleline > a"
    }
  }
}

Alternative Body (Deep Search Pipeline): Use Kryfto's /v1/search endpoint instead to find links on DuckDuckGo, then route the JSON results array into an n8n Split In Batches Node to crawl them automatically!
```
{
  "query": "best enterprise headless CMS tools 2025",
  "limit": 5,
  "engine": "duckduckgo",
  "safeSearch": "moderate",
  "locale": "us-en"
}
```

Processing: Add a subsequent node to parse the returned JSON.
Destination: Send the formatted data to Google Sheets, Notion, or Slack!

3. 🔍 Native Fallback Search Engine (Cutting API Costs)

Need to execute multi-engine searches without paying outrageous API limits?

Traditional platforms force you to buy expensive Google Custom Search or Bing Search APIs for basic discovery. Kryfto's SDK routes headless scraping traffic directly through the native HTML search interfaces of search providers, specifically designed for resilience against bots.

You can instantly find leads or domains without paying a cent in API credits:

Engines: duckduckgo, bing, yahoo, brave, google (all engines work without external API keys — Google CAPTCHAs are solved locally via CLIP vision and Whisper audio).

💡 Why Kryfto? (Cost Savings & Benefits)

Most modern AI and web-scraping architectures rely on expensive third-party APIs (like Firecrawl, Apify, or Browserless). Kryfto replaces these dependencies by giving you complete ownership of your scraping infrastructure.

💸 The Scraping Cost Comparison (100k Requests)

Platform	Cost per 100,000 Pages	Concurrency Limits	Wait-for-Selectors
Firecrawl.dev	~$100.00 / mo	50-100 Concurrent	Paid Extra
Browserless.io	~$200.00 / mo	Route-dependent	Paid Extra
Apify (Web Scraper)	~$50.00+ / mo	Memory restricted	Standard
Kryfto (Self-Hosted VPS)	$5.00 / mo Flat	Scales With Hardware	Included Free

💰 Zero Per-Request Costs: As the table shows, stop paying per-API-call limits. By self-hosting Kryfto on a $5/month DigitalOcean droplet or Railway instance, you can run browser extractions at scale for a flat infrastructure fee. Concurrency is bounded by your hardware and WORKER_GLOBAL_CONCURRENCY setting (default: 2, increase based on available RAM).
🛡️ Total Data Privacy: When you connect local IDEs (Cursor/Claude) or internal databases to Kryfto, your sensitive queries and raw scraped HTML never leave your VPC or touch a third-party analytics server.
🚦 Unmetered Concurrency: You dictate your rate limits. If you need to spin up 50 headless Chromium instances simultaneously, simply scale your worker droplet without hitting external API throttles.
🤖 AI-Context Optimization: Kryfto automatically cleans, minifies, and converts bloated web HTML into dense Markdown. This drastically reduces LLM token consumption and improves context window limits when passing context to Claude or OpenAI.

🎯 Primary Use Cases & Solutions

Use Case 1: Automated Market Research & Price Monitoring

The Problem: You need to track competitor product pricing across 10 different e-commerce sites daily, but they aggressively block basic python requests scripts. The Kryfto Solution:

Enable KRYFTO_STEALTH_MODE=true and feed residential proxies into KRYFTO_PROXY_URLS.
Use the REST API to schedule daily crawl jobs pointing to competitor catalogs.
Kryfto bypasses their bot protection, extracts the prices using CSS selectors ("price": ".amount"), and drops the raw JSON directly into your MinIO storage bucket for your analytics dashboard to query.

Use Case 2: Unblocking AI Coding Assistants

The Problem: Your AI assistant (Cursor, Claude Code) is writing code using outdated documentation because the framework released a new version yesterday that isn't in its training data. The Kryfto Solution:

Install the Kryfto MCP Server into your IDE configuration.
Ask your agent: "Search for the newest Next.js App Router caching docs and update my code."
Kryfto executes the search, extracts the live, up-to-date documentation, and pipes it straight into the AI's context window—allowing it to write perfect, modern code.

Use Case 3: Proprietary Lead Generation Pipelines

The Problem: You want to build a pipeline that finds local businesses on directory sites and extracts their contact emails to automatically pipe into your CRM. The Kryfto Solution:

Connect Kryfto to an n8n workflow.
Step 1: Trigger Kryfto to execute a search for "plumbers in Chicago".
Step 2: Loop through the search results and trigger Kryfto browse extraction jobs on each result's URL, targeting mailto: hrefs or contact page DOM nodes.
Step 3: Automatically POST the collected emails directly into HubSpot or Salesforce.

Use Case 4: Evidence-Based Technical Research

The Problem: Your team makes decisions based on blog posts and Stack Overflow answers with no source verification. You need traceable, trustworthy evidence. The Kryfto Solution:

Use answer_with_evidence to ask a question like "Does React 19 support server components?" — it searches, reads official pages, extracts paragraph-level evidence spans, and ranks them by domain trust score.
Use conflict_detector to check if multiple sources contradict each other on a topic.
Use confidence_calibration to score each claim based on source count, official source presence, recency, and domain trust.

Use Case 5: Framework Upgrade Risk Assessment

The Problem: You need to upgrade Next.js from v13 to v14 but don't know what will break. The Kryfto Solution:

Call upgrade_impact with framework: "nextjs", fromVersion: "13", toVersion: "14" — it fetches migration guides, scans for breaking/deprecated/removed keywords, and rates the risk as low/medium/high.
Combine with github_releases and github_diff to see every commit between tags.
Use query_planner to preview the entire search→read→extract chain before executing.

Use Case 6: Continuous Documentation Monitoring

The Problem: A critical API's docs change without notice, breaking your integration. The Kryfto Solution:

watch_and_act registers the URL with an optional Slack/Discord webhook and a semantic context filter.
Periodically call check_watch — if the page changed, it auto-fires a POST to your webhook with the diff and reports delivery status.
Use semantic_diff with context like "authentication" to filter only changes relevant to you.
For fully autonomous monitoring, use continuous_research_start — it runs search→watch→diff→alert loops on a configurable interval, notifying your webhook of every new finding.

Use Case 7: SLO Monitoring & Production Reliability

The Problem: You need to know if your AI agent's browsing tool is degrading before users notice. The Kryfto Solution:

slo_dashboard shows real-time per-tool success rate, p50/p95/p99 latency, cache hit rate, and freshness.
run_eval_suite runs 10 real-world queries nightly, checking that official sources appear in results — measures precision% and average latency.
replay_request retrieves the exact input/output of any previous call by requestId for debugging.

🥷 Anti-Bot & Stealth Configuration

Kryfto ships with a unified stealth layer (packages/shared/src/stealth.ts) designed to make every HTTP request indistinguishable from organic browser traffic.
