Small, focused tools that do one job well. Each stands alone — and is even better together. No bloat. No dark patterns.

The tools

Everything you need to supercharge your AI coding assistant

lum-browser

Real web access for your AI. Search, follow links, extract and analyze content — get current, sourced answers instead of guesses.

browse search extract analyze

lum-deep-search

Multi‑source research, synthesized. It searches, compares, and cites — so your AI recommends with evidence, not vibes.

research deep-research fact-check

lrok

Share localhost in seconds. Clean, readable subdomains, HTTPS by default, and platform tracking. Like ngrok — with nicer links.

How it works

Three steps to supercharge your AI coding assistant

1

Sign up & get your API key

Login with Google or GitHub (Firebase auth). Create an API key in 30 seconds. No credit card needed.

// Your API key will look like this
const apiKey = "lum_live_a1b2c3d4e5f6..."
2

Configure your AI assistant

Add lum.tools MCP servers to Cursor, Cline, or any MCP-compatible tool. Takes 2 minutes.

// Add to your MCP config (Cursor, etc.)
{
  "mcpServers": {
    "lum-browser": {
      "url": "https://lum-browser.lum.tools/mcp",
      "headers": { "Authorization": "Bearer " }
    }
  }
}

Watch your AI get smarter

Your AI can now search Stack Overflow, browse docs, research technologies, and fact-check claims with real web access.

// Example: AI assistant using lum-browser
await browse("https://docs.python.org/3/library/asyncio.html")
await search("FastAPI async best practices")
await research("kubernetes horizontal pod autoscaling")

Why developers use this

Real scenarios where lum.tools actually saves you time

Stop copy-pasting docs

"Check the latest React docs for useEffect patterns" → AI browses the actual docs, not 2-year-old training data. No more tab switching.

Actual solutions, not hallucinations

Your AI searches Stack Overflow and GitHub issues for real solutions. Stop debugging AI's made-up fixes.

Compare technologies properly

"Postgres vs MySQL for my use case" → AI researches multiple sources and synthesizes a real answer. Not just vibes.

Share demos instantly

lrok your dev server → share "happy-turtle.t.lum.tools" with your team. No more "works on my machine" screenshots.

About pricing

100% free right now while we figure out fair pricing. No credit card. No gotchas.

Free tier forever

Generous limits for real work. Not a 14-day trial or toy tier.

Pay for usage, not hostages

When we add billing, you'll pay for what you use. Not for basic features we arbitrarily locked.

Open source where possible

lrok is MIT. Don't like our hosting? Self-host it. We're cool with that.
