The perfect tool to manage the signature flow of your documents
LibreSign is a web application for electronic signatures (e-Sign) developed by the LibreCode cooperative (Brazilian cooperative specialized in free software development). Its development began at the beginning of 2020, in the midst of the pandemic, when people and companies were migrating their physical documentation to digital, and then there was a need to develop a web solution that could offer the possibility of signing documents, contracts and proposals online with security and agility.
We use PKI technology to generate digital certificate keys. LibreSign is open source (and always will be), which allows it to be audited and customized for various needs and integrated with any system and, of course, maintained by the community.
