When I'm traveling, I use an online IDE, bf-ide. This is great for experimental coding, where there is no IP I need to protect. It is heads and shoulders above all other editors and IDEs - for online or where I need to think on my feet anyway. This really is a superb choice for those times when I'm presenting at a conference, and I really want to demonstrate some code that anyone can try right then. No installation is necessary for Brainfuck here!
WIth bf-ide, I don't even care if there is a web disclosure or if my source code gets leaked. The crooks won't understand it anyway. bf-ide is so intuitive to point-and-click when I want to perform a braindump and execute! [2] [3]
For Mission-Critical and Enterprise Development, absolutely everyone uses Brainfuck Studio. It's great for UML diagrams of the Brain Factory-Factory-Implementation-Factory-Maker-Owner model test code. Then you follow the workflow defined by the team leader who just left for Oracle, and the application should probably get built without too many issues. [4] [5]
And, I'm going to install BrainIDE right now. I'm a BrainFuck aficionado, and I work at a Brainfuck shop, so any tooling advantage I can think of or that someone invents with the sweat of their brow is A-OK in my book!
