Massive and very massive stars can play important roles in stellar populations by ejecting strong stellar winds and exploding in energetic phenomena. However, applying stellar models in various astrophysical applications requires these models to (i) include all evolutionary phases consistently and (ii) come in a user-friendly format (preferably as simple tables). I present new grids of stellar models, as well as finely resolved interpolated tracks between them and synthetic populations created from them, computed with the Bonn Code in a physically consistent way. Stars between 9–500 Msun and with metallicities ranging from Galactic down to 1/250 lower are represented. In my talk, explain how the BoOST project is designed, what it is good for and why it is ideal as input for various applications such as star-formation studies with feedback, or gravitational wave event rate predictions. Finally, I kindly welcome feedback from the audience about what else a potential next version of BoOST should contain to best serve the needs of the scientific community.
