Security best practices when using Robots.txt Generator
What to think about before publishing a file generated by Robots.txt Generator on the open internet.
Generating a file sounds like it should require an app — and historically it did. Robots.txt Generator runs the same thing in your browser tab, with one tap and no signup.
Open the tool: Robots.txt Generator — Everything happens locally in your browser — your file never leaves your device.
Security considerations
Generating a file that ends up on the public internet means anyone can read it. That's fine for non-sensitive content. It's not fine for anything you don't want exposed. Robots.txt Generator doesn't make this distinction for you — but you should make it before you generate.
Safe defaults
- Never embed credentials, API keys, or personal IDs in a file you publish publicly
- Be wary of files on printed material — they can be photographed, copied, and reused
- For sensitive use cases, generate a file that expires (or maps to a server-side resource you can revoke)
Open the tool
No upload, no signup, no daily limit.
