What is PYBOSSA?

PYBOSSA is a technology built by Scifabric, for crowdsourcing or citizen science platforms.

PYBOSSA is an extremely flexible and versatile technology with a multitude of applications that adapt to each specific case facilitating many of the daily tasks that take place in research environments such as museums, art galleries, heritage institutions, libraries of any kind, market research companies, hospitals, universities and all those organisations that manage data or require information from their customers/users -such as airports, shopping malls, banks, hotel chains, etc.

PYBOSSA’s simplicity consists in its easy adjustment to any areas using any of the available templates, this way every customer can then adapt it to their own needs.

PYBOSSA integrates with other data collection products such as Amazon S3, Twitter, Youtube, Google Spreadsheets, Flickr, Raspberry Pi, etc. Through all these integrations PYBOSSA allows data capture for further analysis made by users in a transparent and easy way.

PYBOSSA for python 3

We've finally migrated PYBOSSA to python 3. We're not going to merge into master until we test it in production a bit more, so please, help us by testing it. All you have to do is basically, check out the python3 branch (migrate-python3) and run it. Then, any bug, issue you find, you just report it and we will be happy to help you.

If you want to contribute to the project, please, check the CONTRIBUTING file.

It has the instructions to become a contributor.


Special thanks to Shuttleworth Foundations for funding us and their true support:

PYBOSSA was inspired by the BOSSA crowdsourcing engine but is written in python (hence the name!). It can be used for any distributed tasks project but was initially developed to help scientists and other researchers crowd-source human problem-solving skills!
