Dropbox Sign has no permanently free plan, and its Standard tier bills a minimum of two users at $25 each. MostlySign starts genuinely free and stays flat — $29 a month covers ten people.
Dropbox Sign is a capable, well-built product — this table is about price shape and where each tier starts, not about capability.
| MostlySign | Dropbox Sign | |
|---|---|---|
| Free plan | Yes — 3 documents a month, forever. | No permanently free plan; 30-day trials. |
| Entry price | $0, then $12/mo for unlimited documents. | $15/mo for one user ($10.05 billed annually). |
| Team pricing | $29/mo flat, 10 seats included. | $25/user/mo, minimum 2 users ($17.50 annually). |
| Smallest team bill | $29/mo for up to ten people. | $50/mo for the two-user minimum. |
| Documents | Unlimited on paid plans. | Unlimited signature requests. |
| Templates | 5 on Pro, unlimited on Business. | 5 on Essentials, 15 on Standard. |
| Sealed & timestamped | PAdES + RFC 3161 on every completion. | Completed documents are sealed. |
| Depth | Signing, done carefully. | Deeper — a large integration catalogue and Dropbox itself behind it. |
Dropbox Sign figures taken from its published pricing page on 27 July 2026. Prices vary by region and change — check both before you buy. MostlySign prices are US list.
If you already live in Dropbox, the integration is genuinely the product — documents where your files are, with no extra place to look. Nothing we do replaces that.
It also does not cap signature requests, so if per-envelope limits are what pushed you to look around, that is a reason Dropbox Sign is fine and you may not need us at all. We would rather say so than sell you a problem you do not have.
What we are cheaper at is starting, and staying small. A team of four pays $100 a month on Standard and $29 with us, and a solo user pays nothing at all until the fourth document of the month.
Identical on the free plan and the paid ones.
Three a month, free, forever — with the seal, the timestamp and the audit trail included.
