today, i created an account for bitbucket with my student email-adress. It immediately changed the free license into an academic one.
Is the academical version really free or are any hided costs behind that license?
First of all, I've moved your question to the BitBucket section of this site as this is where people will search to find the answer to these type of questions.
To answer your question: you can take a look at the FAQ of the Bitbucket Pricing page. This clearly states that Atlassian offers free licenses for community or academic projects.
Hope this helps.
