What tool to use to submit to web directories?

What tool do people use to submit their websites to web directories like on Yext and Bright Local? I see people offering gigs on Fiverr and wonder how they get it done so fast

Back in the day (we're talking over a decade ago) I used to submit to directories through software called DigiXmas, and then later on SliqSubmitter. I don't think either of those apps are available anymore, but GSA has a directory submitter in their product lineup:

Yext and Bright Local are popular tools to submit websites to directories swiftly, ensuring consistent listings across platforms. Fiverr gigs likely utilize automation within these tools for faster submissions and directory coverage.
