Site update!

Apr 3, 2017

Hello there! Just a small heads-up on some new features on the website. In short : more bling and comments section. More details inside and stuff.

Yeah, a serious post on April Fools isn't the best idea I've ever had, but there's something that needs to be talked about.

OpenBST 1.0 is out!

Dec 26, 2016

OpenBST 0.3 RC1 Released

Dec 6, 2016

A very experimental release. This is barely usable, so do NOT use it if you are not mentally ready to do some debugging! It includes everything that was teased in the previous post. The tutorial was updated too.

Coming soon in OpenBST 0.3

Nov 26, 2016

0.3 may be the last version before we reach the golden goal of 1.0. Why? Because it is packed with awesome feature that make it the best release of BST yet. Well, I say that every time I make a release anyway, so… whatever, let’s just move on to the cool stuff!

OpenBST 0.2 RC1 Released

Nov 16, 2016

The first Release Candidate of OpenBST is out! Check out the full description here! The main difference you will notice is the new interface. Some bugfixing is required on it, but other than that, it is pretty stable!

Hello World

Nov 16, 2016

Hello! Welcome to the first page of this blog! Various information as well as updates can be found here.



OpenBST is a program that allows you to run and, to a certain level, create interactive fiction and stories. It is built using the Java programming language.

You can download it right now in the Downloads tab! OpenBST is compatible with Windows, Mac OS X, Linux and everywhere else where Java, Swing and JavaFX are supported.

Welcome screen Playing screen


BST is a language used to create stories from simple text files. While you can use the editor built into OpenBST, using the raw BST syntax gives you much more flexibility and unlocks the full potential of OpenBST, with scripting, backgrounds, sounds and much more!

1:This is a node. Its ID is 1

It contains text that will be shown on the screen.
