02Pricing compared
OpenSign is the lower-cost starting point: its Free plan advertises unlimited e-signatures and guest signers. Documenso Free is limited to five documents a month and 10 recipients per document. Documenso Individual costs $25/month; Teams is $40/month for five included users, then $8 per extra user. Platform is $250/month. The pricing page lists annual totals of $300, $480, and $3,000 respectively, matching 12 monthly payments. OpenSign Professional is $29.99/month, or $9.99/month billed annually; that annual option includes up to 240 credits a year. Teams costs $39.99 per user monthly or $19.99 per user monthly on annual billing, with up to 500 annual credits. OpenSign seat caps are not published. Its annual prices are monthly equivalents, not annual totals.
03Features and depth
Documenso has the broader set of features for building signing workflows into a business process. Its Individual plan includes API access for personal use; Teams adds embedded signing, and Platform lists unlimited API access and whitelabel embedded signing. The product also offers templates, direct signing links, team workflows, and a self-hosting option. Its homepage says signatures are compliant out of the box and references 21 CFR Part 11; confirm that claim against your own requirements before choosing it.
OpenSign focuses on PDF e-signatures. Its homepage advertises free unlimited signing, guest signer collaboration, document storage in OpenSign Drive, and completion certificates with access logs. That is a useful fit for straightforward signing and recordkeeping, but its paid plans meter premium sending through credits. The listed credit caps differ by plan and billing term, so check that your sending volume fits. OpenSign’s available materials do not list an API feature in the published plan details.
04Ease of use and learning curve
For basic signing, OpenSign’s free plan keeps the price simple, but its premium credits add a limit to sending methods and volume. The pricing details do not publish seat caps for its paid team plan, so confirm team sizing before committing.
Documenso’s Free plan has a clear five-document monthly cap. Its higher tiers add team, API, and embedded workflows, which may mean more setup than a basic PDF-signing process. The published review notes that self-hosting may take work, and Documenso’s self-hosted licensing price is not published. Neither product’s published materials give enough detail to make a firm claim about setup time or training needs.
