Open source we build on ​

The portal is built on open-source software, and we think you should know what's inside. This page lists the pieces that matter most and where their code and licenses live.

E-signatures: Documenso ​

Signing in the portal runs on Documenso, an open-source e-signature engine released under the GNU Affero General Public License, version 3. We run it unchanged on our own servers. The exact version we run is published at github.com/documenso/documenso/tree/v2.18.0, so anyone can read and check how documents are sealed and signatures are recorded.

Fonts: IBM Plex ​

The text you're reading, and the text in the portal, is set in IBM Plex, a typeface IBM released under the SIL Open Font License. A copy of that license ships beside the font files on this site and in the portal.

Everything else ​

The portal and this help site are built with many smaller open-source libraries, most of them under the MIT license. Each one asks only that its copyright and license notice travel with the software, so we publish the full list:

Something missing?

If you think a notice is incomplete or a library is missing from the list, tell us — see Getting help.
