Enter your domain to start
Fetching your homepage…
- Enter your website URL above and I'll crawl up to 150 pages to build both files.
- The robots.txt includes optional AI bot blocking — a growing SEO best practice for 2026.
- The sitemap.xml follows Google's official spec with priority and changefreq per page.
A robots txt sitemap xml generator is a tool that automatically creates the two files search engines need to crawl and index your website — robots.txt and sitemap.xml. Peplio’s free version crawls up to 150 pages of your live site in about 15 seconds and includes AI bot blocking for 2026 — a feature no other free tool offers.
Two files control whether search engines can find, understand, and index your website — robots.txt tells crawlers where they can and cannot go, and sitemap.xml tells them exactly what pages exist. Missing either file, or having them misconfigured, is one of the most common reasons small websites never rank. That is why a proper robots txt sitemap xml generator is one of the first tools every website owner should use.
I built this robots txt sitemap xml generator for Peplio after discovering my own sitemap was missing 60% of my published pages — I had been writing content for months that Google literally could not find. This tool is the same diagnostic I now run on every website I audit, including client work at Demech Chemical Products.
📌 Key Takeaways
- Crawls up to 150 pages of any live website in under 15 seconds — no signup, no email.
- Generates a complete robots.txt with optional AI bot blocking for 20 bots including GPTBot, ClaudeBot, Google-Extended, and PerplexityBot.
- Creates a valid sitemap.xml with priority and changefreq automatically assigned based on page depth.
- Detects your existing robots.txt and sitemap.xml so you know what to replace vs. keep.
- Both files are instantly downloadable as ready-to-upload .txt and .xml files.
What Is a Robots TXT Sitemap XML Generator?
A robots txt sitemap xml generator is a tool that crawls your website’s internal links and produces two essential technical SEO files — robots.txt which controls crawler access, and sitemap.xml which lists every indexable page. According to Google’s official documentation, both files are critical for websites of any size, but especially for new sites, large sites, and sites with rich media content like comics and tools.
Most website owners either skip these files entirely, use a WordPress plugin that generates incomplete versions, or copy generic templates from online forums. All three approaches leave gaps — missing pages, wrong disallow rules, or zero protection against AI training bots that scrape your original content. This tool solves all three problems in one crawl.
How Peplio’s Robots TXT Sitemap XML Generator Works
This robots txt sitemap xml generator runs a real, safe, and rate-limited crawl of your live website — not a template generator that fills in generic placeholder text:
1. Domain input and SSRF validation
You enter your website URL. The tool validates it, resolves DNS, and blocks any attempt to crawl private or internal IP addresses. This is a standard SSRF protection that most free tools skip entirely — it means the generator cannot be abused to scan internal networks.
2. Existing file detection
Before crawling, the tool fetches your existing robots.txt and sitemap.xml to see what you already have. Status badges show whether each file exists and whether your site uses HTTPS — a mini technical SEO audit in one glance.
3. Smart discovery — sitemap first, then crawl
If you already have a valid sitemap.xml, the tool reads it directly and extracts up to 150 URLs without crawling. If you have a sitemap index file, it reads up to 3 sub-sitemaps automatically. If no sitemap exists, the tool crawls your homepage and follows internal links up to 25 pages deep.
4. Robots.txt generation with 2026 AI bot blocking
The generated robots.txt includes optional blocks for 20 AI training bots — GPTBot, ClaudeBot, PerplexityBot, Google-Extended, Bytespider, Applebot-Extended, CCBot, and more. According to Cloudflare’s bot intelligence data, AI crawlers now account for a significant share of all website traffic — making AI bot control an essential step in 2026.
5. Sitemap.xml with smart depth-based priority
The sitemap.xml follows Google’s official specification exactly, with priority and changefreq automatically assigned by URL depth. Homepage gets priority 1.0 and daily changefreq. Top-level section pages get 0.8 weekly. Deep pages get 0.4 monthly. All URLs get today’s lastmod date for maximum freshness signals.
6. One-click download and manual URL addition
Both files download as robots.txt and sitemap.xml — the exact filenames search engines expect at your root directory. If the crawler missed any JavaScript-rendered pages, paste their URLs manually and regenerate in one click.
Of small websites either have no sitemap.xml or a sitemap missing more than 30% of their actual pages — one of the biggest silent indexing problems on the web today.
Why Every Website Needs a Robots TXT Sitemap XML Generator in 2026
The honest truth — most websites are leaking crawl budget and losing indexing opportunities every single day without knowing it. I discovered this on Peplio when I first ran my own site through a robots txt sitemap xml generator and found that 60% of my published articles were not in my sitemap. Google was finding them slowly through internal links, but many had been sitting unindexed for weeks after publishing.
Generating proper files solves four problems at once:
- Complete URL discovery. Every page in one file, so Google indexes new content within days instead of weeks after publishing.
- AI training bot control. Block ChatGPT, Claude, and Perplexity from scraping your original writing without permission — a rapidly growing concern for bloggers and creators.
- Crawl budget optimization. Tell Google exactly which pages matter and which to skip — admin areas, cart pages, filtered archive URLs, and duplicate content paths.
- Fix broken existing files. Many sites have robots.txt files with syntax errors that quietly block important pages. This tool replaces them with a clean, valid version.
7 Things That Make This Robots TXT Sitemap XML Generator Different
1. Real crawling — not static templates
Most free generators are form-fillers that produce the same generic file regardless of your actual site. Peplio’s robots txt sitemap xml generator actually crawls your live website using a safe, rate-limited bot — you get real URLs discovered from your real pages.
2. AI bot blocking built in — 20 bots
The only free tool I found that blocks 20 different AI training bots by default. Full list includes the newest crawlers tracked at Dark Visitors’ AI bot registry — GPTBot, ClaudeBot, OAI-SearchBot, Meta-ExternalAgent, Bytespider, and more.
3. Sitemap-first logic
If you already have a sitemap.xml (including sitemap index files), the tool reads it directly instead of crawling. This is faster, more accurate for large sites, and far lighter on your server resources.
4. Existing file status audit
Status badges instantly show whether your existing robots.txt, sitemap.xml, and HTTPS are configured correctly — a quick technical health check before you even generate the new files.
5. Depth-aware priority assignment
The sitemap.xml automatically gives higher priority to homepage and section pages, lower priority to deep archive pages. Most free generators give every URL priority 0.5 — valid but useless for signaling page importance to Google’s crawl prioritization.
6. Manual URL paste and regenerate
Paste additional URLs missed by the crawler — like pages behind JavaScript rendering or login walls — and regenerate both files instantly without re-crawling.
7. Zero signup, instant download
No account, no email, no paywall. Files download as robots.txt and sitemap.xml directly to your computer in the exact format expected by every major search engine.
How to Use This Robots TXT Sitemap XML Generator Step by Step
A robots txt sitemap xml generator only delivers value if you deploy the files correctly after downloading. Here is the complete workflow I use for every website audit:
- Enter your domain and click Generate. The tool will crawl your site, check existing files, and return results in 10-15 seconds.
- Review the status badges. Check whether an existing robots.txt or sitemap.xml was found. If both already exist and show “Found”, review the new files carefully before replacing.
- Configure AI bot blocking options. If you rely on AI Overviews and citation traffic, consider keeping some AI bots allowed. If you want to protect your content from training data scraping, enable full blocking.
- Download both files. Download robots.txt and sitemap.xml to your computer first as a backup copy.
- Upload to your website root folder. Both files must live at yoursite.com/robots.txt and yoursite.com/sitemap.xml — not in any subfolder. Use Hostinger File Manager, cPanel, or FTP.
- Submit sitemap.xml to Google Search Console. Go to Sitemaps in GSC, paste your sitemap URL, and click Submit. Google will begin crawling within 24-48 hours.
- Regenerate monthly. As you publish new content, regenerate and re-upload to keep your sitemap fresh and accurate.

Is this robots txt sitemap xml generator really free?
Yes. This robots txt sitemap xml generator has no hidden costs, no signup required, and no email needed. The only limit is 3 crawls per hour per IP address to prevent server abuse — which is more than enough for any legitimate website owner.
How many pages can this tool crawl?
Up to 150 URLs per crawl. The tool prioritizes homepage, section pages, and top-level articles first. For websites over 500 pages, use the manual URL addition feature to supplement what the crawler discovers, or combine with your existing WordPress plugin sitemap.
What is AI bot blocking and should I enable it?
AI bot blocking adds User-agent rules to your robots.txt that prevent crawlers like GPTBot (OpenAI), ClaudeBot (Anthropic), and PerplexityBot from scraping your website to train AI models. Most creators and bloggers should enable this to protect their original writing. However, if you want your content cited in AI Overviews and answers, you may want to keep Google-Extended and PerplexityBot allowed.
Where exactly do I upload the generated files?
Both files must be placed in your website’s root directory — the top-level folder where your homepage lives. In Hostinger, access this via File Manager and navigate to the public_html folder. Final URLs must be exactly yoursite.com/robots.txt and yoursite.com/sitemap.xml — not in any subfolder.
Will this replace my RankMath or Yoast sitemap?
Not automatically. RankMath and Yoast generate dynamic sitemaps at URLs like sitemap_index.xml. You can keep both — use the plugin sitemap for automatic updates and this tool for auditing. Or disable the plugin sitemap and submit the generated sitemap.xml to Google Search Console instead.
How often should I regenerate my sitemap.xml?
Once a month is enough for most blogs. Sites publishing daily content should regenerate weekly. E-commerce sites with rapidly changing product pages should use a dynamic plugin-based sitemap instead of a static generated file, since static files cannot reflect real-time inventory changes.
