The Open, Secure, and Self-Hostable e-Signature Platform

Website • Request a Demo • Pricing • Issues

Signing documents digitally should be fast and easy and should be the best practice for every document signed worldwide. This is technically quite easy today, but it also introduces a new party to every signature: The signing tool providers. While this is not a problem in itself, it should make us think about how we want these providers of trust to work. SPACE-SIGN aims to be the world's most trusted document-signing tool. This trust is built by empowering you to self-host SPACE-SIGN and review how it works under the hood.

Join us in creating the next generation of open trust infrastructure.
