SignedBy vs Dropbox Sign

Dropbox Sign's app plans are reasonably priced per user — but the moment you need API access, it stops being an upgrade tier and becomes an entirely separate product, priced by monthly signature-request volume on top of whatever you're already paying. SignedBy is one flat $7/mo with genuinely unlimited documents, and a self-serve API included in a single higher plan rather than sold separately.

Which one is for you?

Choose SignedBy if…

You want a straightforward send-and-sign tool at one flat, published price — with AI drafting and quoting built in, and a real API included in a plan you can just buy, not a separate volume-priced product.

Choose Dropbox Sign if…

You're already in the Dropbox ecosystem, only need the app (not the API), and per-user pricing works fine for your team size.
