Wekan is still in its infancy. As of me writing this review they haven't released a 1.0 yet. Yet it already has a lot going for it. There are situations where a publicly hosted solution, like Trello, is not viable. I was in that situation myself. Sadly that was before Wekan was born; looking back I'd have chosen Wekan instead of another open source self hosted solution, that had some rough edges. If you have the in house expertise it is easy enough to customize, as it's open source software. In addition it doesn't come with a price tag attached.

The fact that wekan is open source and i being a coder can expand on its features in anyway i like and i also dont have to pay a thing to store my data as it gets recorded on my computer only

Since it is an open source kanban board, I can customise it the way I want. Host it on my system and use it. The board also has a lot of bells and whistles, but a low memory footprint. Other than that, it is a perfect tool for team management.
