OpenNTF was founded in December 2001 by Bruce Elgort and Nathan T Freeman and launched in 2002. The organization provided a hosting site for sharing applications and useful code for the Notes and Domino platform. Projects have included full blown client and web applications, rich client plugins, administrative tools and more. Over the years the scope of OpenNTF has expanded, to include HCL Sametime, HCL Connections, HCL Digital Experience and beyond.

OpenNTF have also hosted developer contests, webinars, and a collaboration solutions news aggregator (Collaboration Today). OpenNTF has been active in the HCL Digital Solutions community at user groups.

Our Domino infrastructure has kindly been hosted and expertly managed free of charge by Prominic. We thanks them for their work, without which we could not continue.

In May 2009 the new OpenNTF Alliance was established. In 2011 the Alliance was replaced by the newly incorporated OpenNTF, which is registered as a non-profit trade organization, as set out in section 501 (c)(4) of US Internal Revenue Code.

Initially OpenNTF provided a snippets database called Code Bin which included over 1000 code snippets between 2002 and 2010. In November 2011 OpenNTF leveraged the XPages technology to replace it and launched XSnippets as a repository for code snippets. In just over three years there were more than 400 contributions. In 2019 we did some work on the look and feel and rebranded the site as OpenNTF Snippets.

In 2015 we transitioned to use the Atlassian suite of developer tools for source control management, issue tracking and continuous integration of projects. We also use Bamboo and artifactory. This provides auto-builds, quicker releases of higher quality projects and direct downloads, as well as easier integration of multiple projects into a project suite like OpenNTF Essentials.

In 2017 we launched OpenCode4Workspace, a sub-site specifically for Connections-related projects using GitHub repositories.

In 2019 HCL agreed a sponsorship deal with OpenNTF and we thank them for their contribution.
