More about the Robots.txt Editor
Analyzing an already-deployed robots.txt file answers whether its current rules are working as intended, but actually changing those rules is a different task, one where seeing the effect of an edit immediately, before it's saved, matters more than analyzing a finished file after the fact. This tool provides a visual interface for editing robots.txt rules, simulating how a crawler would respond to each change live as it's being made rather than only after the file is finalized. Useful for building a robots.txt file's rules visually while watching how each one affects crawler access in real time, testing a rule change's effect immediately before committing it to a live file, or authoring a new robots.txt from scratch with instant feedback on what each line actually blocks.
Visually edit and test robots.txt rules with live crawler simulation. The Robots.txt Editor is one of 900+ free developer tools on Toolblip - all open to use without a signup.
