Should I use Flockbay or GDevelop?

By Eduardo Orellana · Updated

Flockbay is free on your own Claude or ChatGPT plan. Claude Pro or Max, or ChatGPT Plus or higher, builds a real Godot project in the Godot editor. Claude Free and ChatGPT Free do not run here. More models are optional, a credit reload at API prices. Windows today. The engine is the official Godot release. Use GDevelop for a free open-source editor in a browser tab that exports to the web; use Flockbay for a Windows app on the official Godot release, where your own Claude or ChatGPT writes the code.

GDevelop deserves the credit it gets

It is free, it is open source, and it is a serious no-code engine rather than a toy. The event system is readable, the editor runs in a browser or as a desktop app, and it exports to web, desktop, Android and iOS without a paid tier standing in the way.

For someone who brings their own Claude or ChatGPT plan, that combination is very hard to argue with. It costs nothing, it locks you into nothing, and the community around it is active.

Anyone comparing the two should start from that, because on price and openness GDevelop wins outright and no amount of feature talk changes it.

Dimension is not the thing that decides it

Start a project in Flockbay and the first thing it asks is which kind of game, 2D or 3D, shown as two pictures. There is no default and nothing gets made until you pick one. Pick 2D and what opens is already running: a sky, a band of scenery along the horizon, ground with a ledge and a floating platform, and a person who walks, falls and jumps under the keys you press.

That is not a compatibility mode. Ground in a flat project is a tile layer you drag on and drag off, and the tiles, the edges and the collision are all worked out from which cells you covered — paint the same cells in a different order and the world comes out the same. Whether ground stops a walker is declared per material, so a platformer's solid block and a top-down floor are painted identically and only one of them blocks you. The catalogue you place from is 90.8% sprites: 55,073 objects out of 60,648.

So the old triage — 2D over there, 3D over here — is the answer most comparisons still give, and it no longer sorts anything. What does sort them is how you want the logic made, where you want the tool to run, and what you are left holding if the tool goes away. Those are the next three sections, and they are the ones worth arguing about.

Events versus a described behaviour

GDevelop's events are explicit. You assemble conditions and actions, and the resulting logic is visible as a list you can read. When it does something strange, the cause is a row you can point at.

Flockbay replaces that with its AI, which writes GDScript into your project from what you describe. The advantage is that complicated behaviour does not become a long list you must hold in your head. The cost is that the logic is not laid out for inspection unless you go and read the code, which you can, because it is a normal Godot project.

One is assembling the logic. The other is describing it and judging the result by playing. Neither is cheating and they suit different temperaments.

Where each one runs

GDevelop runs in a browser or as a desktop app, and it works offline. Flockbay is desktop only, for Windows, and building requires an internet connection because the chat, asset generation and world data all come over the network.

Playing what you built does not need the connection — the game runs locally on the copy of Godot bundled with the app. But building does, and that is a real point in GDevelop's column.

Both put a real engine underneath your game. GDevelop has its own runtime; Flockbay sits on Godot, which is open source and which your project remains portable to.

What openness protects you from

GDevelop being open source means the tool cannot be taken away from you. If the project stopped tomorrow the code exists and your games keep building. That is a real form of safety and it is fair to weigh it heavily.

Flockbay is not open source, so the equivalent protection has to come from somewhere else. It comes from the project format: your game is an ordinary Godot project on your own disk, and Godot is open source and widely used. If this app disappeared, the folder still opens and the game still runs.

That is a weaker guarantee than GDevelop's and a much stronger one than a closed editor with its own file format. Knowing which of the three you are getting is the useful thing.

Cost, and the recommendation

GDevelop is free with optional paid services. Flockbay is free on your own AI: your Claude or ChatGPT plan, your own agent, or an API key.

Take GDevelop if you want your logic laid out as rows you can point at, if you need the editor in a browser tab or working with the wifi off, if the game has to end up as a link or on a phone, or if open source is the part you will not compromise on. Those are four good reasons and not one of them is about dimension.

Take Flockbay if you would rather describe the behaviour and judge it by playing, if you want the game running natively on your own machine, and if you want to end up holding an ordinary Godot project. That answer comes out the same whether the game you keep sketching is a level or a landscape, and it assumes you have no intention of writing code either way.

Questions

Is GDevelop really free?
Yes, and open source. It sells optional services on top, but the engine itself is free to use and that is a genuine advantage over any paid tier.
Can GDevelop make 3D games?
It has 3D features, but it is a 2D engine at heart. For a full 3D world it is not the tool the comparison flatters.
Can Flockbay make 2D games?
Yes, and you choose 2D or 3D when you create the project. A flat project opens playable, with ground you paint as tiles, a character whose speeds, gravity and jump are controls rather than code, and a catalogue that is mostly sprites.
Can I export to mobile from Flockbay?
It is aimed at a game running locally on Windows. GDevelop has the more established mobile export path.
Does Flockbay work offline?
Playing does. Building does not, because the AI, asset generation and world data all come over the network.
Do I own my project in either?
In both. GDevelop is open source, and a Flockbay project is an ordinary Godot project on your own disk.
