CG Colleen G. 1/14/2026 "Affordable, Easy to Use, but Needs UX Tweaks" 5/5 What do you like best about OpenSign? I really appreciated OpenSign's free trial, as it was really helpful to give me a sense of whether it was a product I wanted to move forward with. Their overall pricing is reasonable, which is a big plus. The signature collection feature is the one I use the most because it's just really straight ahead, with an easy drag and drop functionality. I also found the initial setup very easy and got started right away. Review collected by and hosted on G2.com. What do you dislike about OpenSign? One of my forms had a lot of yes/no radio button questions, and the radio button functionality didn't interact well with my document. Getting that set up was somewhat cumbersome, and the output that my receiver got was less than elegant. That interface definitely could use some attention. Review collected by and hosted on G2.com. What problems is OpenSign solving and how is that benefiting you? I use OpenSign to collect signatures from business partners and track document status. It helps send documents without needing extra tools and lets me use templates to avoid recreating documents. It makes managing agreements smooth and efficient.

Small-Business (50 or fewer emp.) 11/3/2023 "Finally the long awaited free & open source alternative to DocuSign" 5/5 What do you like best about OpenSign? Straight forward & legally recognized document signing which makes signed documents immutable, multiple signers, option to draw or upload signature, etc. The fact that its an open source tool and still does not compromise on any functionality. It was super easy to deploy, I just cloned the repo and ran "make build" and it was up and running locally. Plus the hassle free option of cloud hosted solution is cherry on the cake. Another thing I loved about OpenSign is their active community, with around 2k stars on github in a few days of launch they have one of the most engaged community of developers who have their eyes on the code and community support is awesome. I tried mailing them about my query and got a reply in less than an hour from the customer support. Review collected by and hosted on G2.com. What do you dislike about OpenSign? For the self-hosted version, they only support MailGun as the email provider, I would love to have the option to use SendGrid. Review collected by and hosted on G2.com. What problems is OpenSign solving and how is that benefiting you? Its saving me a ton of money by allowing me to sign documents at the fraction of the cost of DocuSign.
