About the Robots.txt Generator
Robots.txt Generator builds a perfectly-formatted robots.txt file you can drop into the root of any website to tell search-engine crawlers what to index and what to skip. Pick a default policy (Allow all or Disallow all), add Disallow and Allow paths, declare one or more Sitemap URLs and — if you need finer control — append custom User-agent blocks for Googlebot, Bingbot or AhrefsBot. The tool emits the exact syntax of the Robots Exclusion Protocol so you avoid the typos that silently break crawl rules. Copy the output to your clipboard or download it as a .txt file ready for upload.
How to use
- Choose a default policy — Allow all or Disallow all.
- Add Disallow paths and (optionally) Allow paths, one per line.
- List your Sitemap URL(s) and any custom User-agent blocks.
- Click Generate, then copy or download
robots.txt.
Benefits & key features
- Produces spec-correct robots.txt every time — no hand-written typos.
- Handles custom user-agents, crawl-delay and multiple sitemaps.
- Copy-to-clipboard and direct download supported.
- Everything stays in your browser — no upload, no account.
Pro tip
Upload the generated file to your domain root (/robots.txt) and test it in Google Search Console's robots.txt tester before going live.
Why choose toolsfy for Developer tools?
Developers already have editors, linters and one-off scripts that do half of what these utilities do — but nobody wants to paste a JWT into a random cloud decoder, or send an AES-encrypted sample through someone else's server. toolsfy's dev utilities are deliberately tiny, zero-dependency and 100% client-side so they can become part of a muscle-memory workflow you actually trust with production data.
Common use cases
- Full-stack developers formatting a gnarly production JSON payload to figure out which field the front-end is mis-parsing.
- DevOps engineers minifying a snippet of JavaScript or CSS inline during a code review, without reaching for a Node build step.
- Security engineers hashing or Base64-encoding a small test vector for a quick regression check on an authentication flow.
Frequently asked questions
Do these tools send my code or payload to a server?
No. Everything runs inside this tab. Even large minification jobs stay local — you can run the tool with DevTools → Network tab open to confirm.
Is the output deterministic and reproducible?
Yes. The same input always produces the same output, because the libraries are versioned (the exact CDN versions are pinned in common.js).
Can I integrate the underlying logic into my own project?
The tools rely on well-known open-source libraries (js-yaml, pdf-lib, clipboard API). Swap toolsfy for the npm packages of the same libraries once you are ready to automate.
