What is Robots.txt Generator?
Robots.txt Generator is a free, browser-based tool in the SEO Tools suite. Generate a standards-compliant robots.txt with per-user-agent rules, allow/disallow paths, sitemap URL, crawl-delay and host directives. Copy or download.
The headline benefit: build a robots.txt with allow/disallow rules, sitemap & crawl-delay.
Unlike most online tools that upload your file to a server, process it, and send it back, Robots.txt Generator runs entirely in your browser. Open DevTools → Network while using it and you'll see zero file-upload requests — only static assets (JavaScript, CSS, fonts) load. Your data never leaves your device.
Why use this robots.txt generator?
Three reasons EasyFileKit's Robots.txt Generator stands out from the crowd:
- **Private by design** — all processing happens locally via JavaScript and WebAssembly. No server ever sees your input.
- **Instant** — no upload wait, no queue, no server round-trip. Results appear the moment you act.
- **Free & unlimited** — no accounts, no watermarks, no daily caps. Use it as many times as you like.
How to use Robots.txt Generator — step by step
Here's the complete walkthrough. Everything happens instantly in your browser:
- **Step 1.** Add rule blocks — one per user-agent (use * for all bots).
- **Step 2.** For each block, list Allow and Disallow paths (e.g. /, /admin/).
- **Step 3.** Optionally set a crawl-delay and a Host directive for mirror sites.
- **Step 4.** Enter your sitemap URL, then copy or download the generated robots.txt.
That's it. No sign-up, no upload bar, no waiting. If something doesn't work as expected, check the FAQ below.
Common use cases for Robots.txt Generator
People reach for Robots.txt Generator in a few recurring situations:
- When you need the result **now** and can't wait for a server-based tool to upload, queue, and process your file.
- When your file is **private or sensitive** — financial documents, personal photos, medical PDFs — and you don't want it travelling across the internet.
- When you're on a **slow or metered connection** — uploading a 50 MB file just to compress it makes no sense when the same work can happen locally.
- When you've hit the **daily limit or paywall** on another "free" tool site.
Privacy: what actually happens to your data
This is the single most important point about Robots.txt Generator, so it deserves its own section.
When you use this tool, your input is processed by JavaScript running in your browser tab. The code is downloaded once (cached afterwards) and executes locally on your CPU. At no point is your file, your text, or your input data transmitted to any server.
You can verify this yourself in under 30 seconds:
- Open Robots.txt Generator in your browser.
- Press F12 to open DevTools.
- Switch to the Network tab and tick "Disable cache".
- Use the tool — drop a file, type text, whatever the tool needs.
- Watch the Network log. You'll see only static assets (JS, CSS, fonts, icons). No request contains your data.
This isn't a setting you toggle or a promise in a privacy policy — it's how the tool is architecturally built. There is no upload endpoint to call.
Frequently asked questions about Robots.txt Generator
Q: Where should robots.txt live?
A: At the root of your domain: https://example.com/robots.txt. Crawlers look only at that exact URL.
Q: Does Disallow block indexing?
A: No — Disallow blocks crawling, not indexing. A disallowed page can still appear in search results if linked from elsewhere. To fully block indexing, use the noindex meta tag or X-Robots-Tag header.
Q: What does crawl-delay do?
A: It asks compliant crawlers to wait N seconds between requests. Google ignores it (use Search Console settings instead), but Bing and Yandex honor it. Useful for low-traffic servers.
Q: Can I have multiple User-agent blocks?
A: Yes — add as many as you need. Each block applies only to its named bot. Use * as a catch-all at the end.
Q: Should my sitemap be in robots.txt?
A: It's a good practice — adding `Sitemap: https://example.com/sitemap.xml` helps crawlers discover it. Major search engines also accept direct sitemap submission via their webmaster consoles.
Robots.txt Generator: EasyFileKit vs server-based tools
Most "free" online tools that do what Robots.txt Generator does follow the same model: you upload your file to their server, they process it with a backend script, then they send the result back. Here's the honest comparison:
| | EasyFileKit | Server-based tools |
|---|---|---|
| **Your file leaves your device?** | Never | Yes, uploaded to a server |
| **Speed** | Instant (no upload) | Slower (upload + queue + download) |
| **Privacy** | Complete | Your file is on someone else's computer |
| **Cost** | Free, unlimited | Often capped or "premium" gated |
| **Works offline** | Yes (PWA) | No |
Server-based tools aren't evil — they exist because some tasks genuinely need heavy backend compute. But for everything Robots.txt Generator does, client-side processing is strictly better for you.
Under the hood: how Robots.txt Generator works
Robots.txt Generator is built with modern browser APIs. Depending on what it does, it may use:
- **Canvas API** — for image manipulation (pixel-level access, filters, resizing).
- **Web Crypto API** — native, hardware-accelerated cryptography (AES-GCM, SHA-256, PBKDF2) for any encryption or hashing.
- **pdf-lib / pdf.js** — fully client-side PDF creation and rendering.
- **MediaRecorder API** — for capturing screen, audio, and video.
- **WebAssembly** — for heavy codecs (image compression, media processing).
All of these run inside your browser's sandbox. They cannot access your filesystem (beyond files you explicitly choose), cannot make network requests with your data, and cannot run persistently in the background.
Pro tips for getting the most out of Robots.txt Generator
- **Bookmark the tool** — it works offline once cached, so you can use it even without a connection.
- **Install EasyFileKit as a PWA** — open the browser menu and choose "Install app" for a standalone window and offline access.
- **Use it on mobile** — every tool is fully responsive and works on phones and tablets, not just desktops.
- **No file size anxiety** — because nothing uploads, you can process large files that server-based tools would reject or charge for.
