Buy a Feature

If you look at the wishlist you’ll see dozens of wishes from users. Unfortunately we can only realize a few of them due to our very limited resources. If you really, really, really need a particular feature there might be a solution: pay for it. Docear is open source and anybody can modify the source code an hence add new features. If you know a software developer, ask him to help you. There are also plenty of freelancers boards like PeoplePerHour or There you can post your requirements, and freelancer will make their offers (usually with pretty reasonable pricing). If you have accepted an offer, please let us know so we do not develop the same feature the freelancer is developing. And you are highly welcome to send us the source code of the new feature. We will check the code and maybe integrate it into the official Docear release which also means that we would maintain the feature, so it works with future versions of Docear.

If you consider to ask an external software developer for help, please consider the following issue:

Docear has a superb add-on system. Add-ons are like little independent programs that extend or change the functionality of Docear. That means, if your new feature is realized as an add-on, it will most likely work with future versions of Docear. So you can use your feature even if we do not integrate it directly into Docear. The downside: It takes at least 10 to 20 hours for an experienced software developer to understand how the add-on system of Docear works. A not so skilled programmer might even need a week or so.¬†Alternatively, the freelancer could just modify the current release of Docear. This will take significantly less time but it has a downside, too: There is no guarantee that the new functions will work with future versions of Docear. Of course you can send us the modifications and we will have a look at them and maybe we will integrate them into the main branch of Docear. But maybe we won’t.

If you want your feature permanently integrated to Docear, there is an alternative. First of all, submit your wish to our idea tracker. Wait at least a few days for our reply. If you are lucky we want the feature anyway. However, if we don’t, send us an email in which you specify as detailed as possible what you want and tell us what you are willing to pay. In our team we will discuss whether we generally want for Docear the feature you propose. If we decide that we like your proposal we will forward it to some students and volunteers who are working for Docear. If they have time (and consider your offer as high enough) they will contact you to discuss further details. Since we know that the students are writing solid code, we guarantee to integrate and maintain your feature in the official Docear release at least for a year (and probably for ever). However, please be aware that we cannot take any responsibility if the student does not finish the job or whatsoever. We just bring you in contact with the student. Everything else (payment, milestones, project specification, …), is between you and the student.
