This page details the planning of Inkscape's 2023 hackfest in Bensberg, Germany. The hackfest will take place on March 13-17, 2023. We are looking to bring together a group of 11 attendees. but do not let that number discourage you from throwing your hat in the ring in case we reach/go over it. We are fully booked and the number of participants is final now.

This hackfest is a standalone event and not organized around any other event or FOSS conference.

Previous events: Hackfest2019 Saarbrücken, Hackfest2019 SCALE, Hackfest2018 Kiel, Hackfest2018 LGM, Hackfest2018, Hackfest2017, Hackfest2016, Hackfest2015.


It's a hackfest! We will work on Inkscape bugs, new features, packaging, website issues, ... in fact anything that can benefit from us being physically in the same space. And let's not forget about the social component - all work and no play makes Jack a dull boy! We get to hang and talk and laugh in person since we usually only meet virtually :).


Bensberg is part of Bergisch Gladbach, a city in the western part of Germany, about 15 km east of Cologne. It is beautifully located in the countryside, surrounded by lush forests slightly elevated to give a great view depending on weather conditions. The nearest airport is Cologne Bonn (CGN) which is an international airport.

Our host is the Generali Akademie, the dedicated education and conference center of the Generali Group in Germany (it's an insurance company). The location's special appeal is its all-inclusive package: conference rooms, hotel rooms and full catering service are conveniently provided on-site.

(full disclosure: as an employee, RdH has been there multiple times)

Travel information

Your main destination is Cologne.

from Cologne/Bonn airport (CGN) to central station

Take the tram S19 to Cologne central station. Travel time is about 15 minutes. The tram is scheduled every 20 minutes for most of the day.

from Cologne central station to Bensberg (public transportation)

Take the bus Schnellbus SB 40 that directly connects Cologne central station to Bensberg (final stop). Travel time is about 30 minutes. This bus is scheduled every half hour between 6am and 8pm.

Once you arrive at the bus stop in Bensberg, you can either take a taxi or walk about 900m to our location.

from Cologne central station to Bensberg (cab)

Our hosts have special conditions with a local cab service (https://www.transfer-nurdogan.de/). I can't tell if that's cheaper compared to the others or just for a classy look:

  • 45 € (standard)
  • 50 € (large cab, suitable for sharing)


Hotel rooms are provided on-site and are part of our conference package, no dedicated booking necessary.

Cost calculation

per attendee

The fee for housing and catering per attendee is 837 € and is due on the last day of the event, payable via debit or credit card (VISA, Mastercard) by each individual themself. A billing address needs to be provided in advance.

hotel room incl. breakfast  127 € x 4 days =    508 €
catering service (days 1-4)  70 € x 4 days =    280 €
catering service (day 5)     49 € x 1 day  =     49 €
--------------------------------------------    837 €

joint event

The meeting room fee is 900 €. Additionally, we have allocated a budget for alcoholic drinks as those are not included in our otherwise "all inclusive package".

meeting room (days 1-5)     180 € x 5 days =    900 €
alcoholic drinks            500 € x 1      =    500 €
--------------------------------------------  1,400 €


Using the interim results from above, this brings us to a total cost (excl. travel) of up to 9,770 €. The fixed part of the total cost (i.e. everything without alcoholic drinks) is 9,270 € and has been payed in full by the SFC by international wire transfer. The total amount for alcoholic drinks - if any - will have to be payed on-site on the last day of our event (RdH will take care of this and do the reimbursement process later).

participants                    837 € x 10 =  8,370 €
joint event                    1400 € x  1 =  1,400 €
--------------------------------------------  9,770 €


  • Hackfest Bensberg 2023 takes place on March 13-17, 2023
  • deadline to apply for attendance is February 01, 2023


In an initial poll, 8 people expressed their interest/availability for this hackfest. Based on this number we are planning for 10 attendees. Should more people be interested, we'll try our best to expand - the earlier we know, the better! If we don't reach 10, we will try to scale down our booking. If you are interested, don't hold yourself back!

I want to attend!

That's great! Be aware of the following:

  • You are making a commitment here which will produce expenses for the project. Please make sure that you will be able to honor this commitment! (Are you table to take the week off from your day job? Are you able to travel? etc.)
  • Every attendee will have to pay their fee of 837 € on the last day of the hackfest. There is something special about payment methods that we will have to talk about privately, I'll contact everyone. (After the hackfest you can follow the reimbursement procedure.)
  • You are eligible to apply no matter if you participated in the initial poll/"call for interest". (Only in case we end up being seriously overbooked and cannot accommodate for everybody we will take the initial poll into account.)

Now go ahead and add yourself to this table (or ask in this issue and it will be done for you):

Join the Signal phone group to keep in touch with everyone during the event.
