OpenSign vs Dropbox Sign
Both are alternatives to DocuSign. Here's how they stack up — verified facts, no spin.
Also searched as Dropbox Sign vs OpenSign — same comparison, one verdict.
OpenSign is open source (AGPL-3.0 (verify current terms — this project's licensing has changed)) and Dropbox Sign is not (Proprietary (hosted service)) — so the real question is whether you want to own the e-signature stack or rent it.
OpenSign
A self-hosted signing platform aimed squarely at DocuSign's feature list.
OpenSign covers templates, bulk sending, multiple signers, reminders and an audit trail, with a self-hosted deployment and an interface deliberately familiar to anyone coming from DocuSign. Its aim is feature parity rather than reinvention, which makes it the shortest retraining path for a team that already has a signing process it likes. It is smaller and less established than Documenso, and the project's licensing has moved over time, so check the current terms against your intended use before you commit.
Dropbox Sign
The straightforward commercial alternative, at roughly half the price.
Dropbox Sign, formerly HelloSign, does the ordinary signing job well at about $20 per user per month against DocuSign Standard's $45, with a clean interface and a genuinely good API that developers tend to prefer. Listed because a great many companies evaluating DocuSign do not want to run a server — for them the real choice is between commercial vendors, and pretending self-hosting is always the answer would not serve the reader. It is proprietary and hosted, with fewer enterprise routing features than DocuSign.

Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose OpenSign
if you want the source and the option to fork it, and you would rather run it on your own hardware, and your data should stay on machines you control.
Choose Dropbox Sign
if roughly half DocuSign's per-seat price.
Neither, yet
if both carry a real cost you should weigh first — licensing has shifted historically — check current terms yourself, and proprietary and hosted — contracts sit with the vendor. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
OpenSign vs Dropbox Sign — common questions
Is OpenSign a better fit than Dropbox Sign for e-signature?
It depends on what you are optimising for, and the honest split is this: OpenSign scores 84 to Dropbox Sign's 34 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Dropbox Sign earns its place on a different axis — roughly half DocuSign's per-seat price. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
OpenSign keeps its data local or in open formats, so leaving is an export rather than a negotiation. Dropbox Sign keeps your data on its own infrastructure, which is the part to plan for: confirm the export path before you commit, not when you are already trying to leave.
Is OpenSign free?
OpenSign: Free to self-host. Managed cloud tiers are paid.. The other side of this comparison, Dropbox Sign, is priced as About $20/user/month for the standard tier. Checked 2026-08-04.. "Free" here means no licence fee — if you self-host it you still pay for the server, and the running cost row above is our honest estimate of that.
Can I self-host OpenSign?
OpenSign can be self-hosted; Dropbox Sign cannot, so it stays on the vendor's infrastructure whatever you do.
Are OpenSign and Dropbox Sign both alternatives to DocuSign?
Yes — both appear in our DocuSign comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off DocuSign and now choosing between the two replacements, which is a narrower and much easier question.
