Out of boredom, yesterday I created an unofficial tool that watches the PocketMine repo updates (using the GitHub Events API). It basically provides the latest development build for every GitHub branch that has a commit since yesterday. Link: http://pmt.mcpe.me/pmb/ Please make sure that you read the Notes section on that page. If you want an API, refer to the Web API section on that page. Please note that this website is unofficial, and is made in the intention to provide a mirror/backup download for the official Jenkins server, and as an alternative to those who don't like Jenkins because they don't like clicking so many links.
