Supported application stack

Semaphore supports Ruby applications and provides UI for configuring version of Ruby. It also generates database.yml for your Ruby application based on selected database engine.

Apart from Ruby the following languages are also available: JavaScript (Node.js), Java, Python, C/C++ and Perl. For those languages application has to be configured manually in your project’s custom build commands. If you would like another language to be included out of the box, send us email or install it manually.
