What is Stage Engine? The app for building games

Stage Engine is a desktop application for Mac and Windows. You download it, install it, and use it to build a 3D video game without writing any code. The company that makes it is Flockbay, and the engine underneath it is Godot, which is open source.

The phrase itself is shared with things that have nothing to do with games. Search for it and a lot of what comes back is rocketry, where the first-stage and second-stage engines are the parts of a launch vehicle that fire in sequence. Some of the rest is theatre and lighting control software. This page is about neither, and saying so plainly is cheaper than pretending the collision is not there.

If you came looking for propulsion or for a lighting desk, nothing further down will help you. If you came looking for the thing that builds games, that is all of the rest of this page.

Concretely: you open the app, start a project, and build a place. Ground and hills, water, weather, some buildings, some characters. You do that with your hands, in a builder that behaves like a level editor rather than a chat window, because placing a hill where you want it is faster than describing where you want it.

Then you ask for behaviour. The boat should sink if you overload it. The guards should notice the missing crate. The storm should come in at dusk and make the harbour unusable. Director 1 writes the GDScript that makes each of those true, inside your project.

Then you play it. Locally, on your own machine, at your machine's framerate. Most of what happens next is you deciding the storm arrives too early and the guards notice too fast, and saying so.

Build, ask, play, judge. That is the loop and it is most of the hours. Nothing here produces a finished game from one sentence, and nothing on this site will suggest otherwise.

Godot is the engine. It is open source, developed by a community rather than by us, and games ship on it. A copy of it lives inside Stage Engine, so you never install it separately and never pick a version.

Your project is a real Godot project in a folder on your own disk. Not an export, not a save file, not a format that only this app can read. If you ever want to open it in Godot directly, or hand it to someone who knows how, you can.

Stage Engine is the app around all of that: the builder you place things in, and Director 1, which writes the code. People call the whole thing a game engine in conversation and that is close enough, but the precise sentence is that Godot is the engine and Stage Engine is what sits around it.

A Mac or a Windows PC. There is no browser version, no phone or tablet version, and no Linux build. It is an application you install, and that is deliberate rather than a stage it has not reached yet, because a world with terrain, weather and a lot of moving things is not something a browser tab runs well.

An internet connection while you build. Director 1, asset generation and world data all come over the network, so this is not an offline tool and there is no degraded mode waiting behind a connection failure. Playing the game you already built does not need the connection, since that runs on the copy of Godot inside the app.

The download is free and there is a free plan. Indie is $10 a month and Pro is $50. What the paid plans buy is more usage, not a different engine, extra features or a better version of the app. There is no team, seat or enterprise tier, because it is one application on one person's machine.

Someone who has a specific game in their head and no intention of learning to program to get it out. Non-technical, in the way this is meant, describes who writes the code and nothing else. It does not mean you cannot tell whether the game is any good. Judging it is the job you keep, and it is the harder half.

It suits people willing to spend real hours inside a world they are building. It does not suit someone who wants something game-shaped by the end of the afternoon, and there are faster tools for that which are honest about being that.

It also does not suit anyone who needs to work on a school Chromebook or a tablet, or whose project already lives in another engine, since nothing transfers between engines.
