FSFE Summit: OPOSSO empowers sustainable business models

The 1st Summit of the Free Software Foundation Europe (FSFE) will be held September 2nd - 4th at the BCC Berlin. Kicking off on Thursday (Sep. 2nd) with the motto "Let's talk about business" various business models and experiences around Free Software will be discussed. Dr. Johannes Loxen, CEO of SerNet, will be one of the speakers on this day with a lecture on OPOSSO, a new platform for Subscription Management.

At 4:15 p.m. Loxen introduces the free software project OPOSSO, published by SerNet and under AGPLv3. OPOSSO is a platform for the management of subscriptions and makes it easier for developers to establish a sustainable business model on a subscription basis. OPOSSO automates the handling of high subscriber numbers, start and end dates of the subscriptions and the combination with web stores and software repositories. It follows the premise that the lower the price for the subscription is, the more the subscription process itself must be automated.

OPOSSO won the silver OSBAR 2015 – the Open Source Business Award of the OSB Alliance. In addition, the project can be observed live at

The FSFE Summit will bring together FSFE members and supporters from all over Europe. The Summit is organized as subconference of the QtCon which combines five free software Communities and projects under one roof: Qt Contributors, VideoLAN, KDAB, KDE – and FSFE.

OPOSSO source code available on GitHub


SerNet launched <link http:>OPOSSO - the OPensOurceSubScriptionpOrtal last year. OPOSSO is in use i.a. as a platform to <link https: _blank>manage the subscriptions for our own SAMBA+ packages. The source code is publicly available now, the software is licensed under the AGPLv3.

OPOSSO is a free subscription management portal for the marketing of (open source) software: In the past, open source developers who wanted to sell their software project as subscriptions quickly realized that there is no free solution for subscription management, that supports managing passkeys bought via an online store. OPOSSO provides a remedy. Unfortunately the currently available proprietary solutions from Red Hat or SUSE are not disclosed and are unsuitable for smaller projects. The system manages software subscription credentials and runtimes in interaction with a webshop. 

SerNet developed the idea for OPOSSO in 2014 and implemented it in a joint venture with beclever.

sambaXP Logo

From May 10th - 12th 2016 the 15th SAMBA eXPerience took place. The conference was hosted by SerNet and the <link https: _blank samba>international Samba Team. Audio recordings and slides of the presentations are now available at <link http: _blank samba>

This year the sambaXP made it to Berlin for the first time. Despite of the new venue the event was a meeting point for developers and users from around the world which was also reflected in the variety of topics: Stefan Metzmacher kicked off the conference with a deep insight into Badlock (<link https: archive_data sambaxp2016-audio wed sambaxp2016-wed-stefan_metzmacher-badlockbug.mp3 external-link-new-window metzmacher: badlock bug>audio / <link https: archive_data sambaxp2016-slides wed sambaxp2016-wed-stefan_metzmacher-badlockbug.pdf external-link-new-window metzmacher: badlock bug>slides), while Denis Cardon told "Samba 4-AD, it works: stories of battles fought and won" (<link https: archive_data sambaxp2016-audio wed sambaxp2016-wed-denis_cardon-samba4aditworksstoriesofbattlesfoughtandwon.mp3 external-link-new-window cardon: it works stories of battles fought and won>audio / <link https: archive_data sambaxp2016-slides wed sambaxp2016-wed-denis_cardon-samba4aditworksstoriesofbattlesfoughtandwon.pdf external-link-new-window cardon: it works stories of battles fought and won>slides). Cardons lecture is a proven toolbox to prepare and execute the migration of large networks to Samba4-AD.
