When diving into the world of game development, choosing the right engine can dictate the entire trajectory of your project. I have spent years jumping between Defold and Unity, but I also invested a massive amount of time into Godot. The recent release of Godot 4.0 marks a monumental turning point for that engine—it is practically a brand-new tool, which pulled me right back into its ecosystem. In this post, I will break down exactly where Godot stands today, evaluate if it is a reliable choice for professional developers, and see how it holds its ground when directly compared to Defold.
Which game engine is better?
The answer is simple: it depends entirely on your specific project. There is no such thing as a universally perfect game engine. Sometimes writing your own custom engine is the smartest move; other times, jumping into Defold, Godot, Unity, Unreal, Phaser, or CryEngine makes far more sense.
The most logical way to decide is to build a prototype of your game in both engines and compare the workflow. But let’s be real—nobody has the time to do that. Beyond raw technical specs, several other factors heavily influence this decision:
- Accessibility and user experience
- Reliability
- Community support
- Ease of use and the learning curve
- Hard limitations
- Platform support
This comparison sidesteps the usual flame wars and focuses on the concrete differences developers actually care about. Neither engine is inherently superior; they just solve different problems in different ways.
What are Defold and Godot?
Defold
Defold is a free game engine originally built by former Avalanche developers. King, the studio behind Candy Crush, bought it in 2013 and released it to the public for free in 2016. Since 2020, it has been operating independently under the Defold Foundation, with its source code available on GitHub.
Defold is a modern, rock-solid, and incredibly lightweight engine. It features a plug-and-play editor and focuses heavily on 2D game development, specifically targeting mobile and web platforms. While you can view the source code online, you cannot sell the engine itself as your own product. Because of this licensing restriction, it is not considered strictly open-source. This is the primary licensing difference between Defold and Godot.
Godot
On paper, Godot looks incredibly similar: it is a free, open-source, lightweight engine with a plug-and-play editor. However, it targets both 2D and 3D game development.
It was initially built around 2001 by developers in Argentina—about 8 years before Defold hit the scene. It went fully open-source in 2013. A year later, it joined the SFC foundation, followed by rapid releases of version 2.0 and 3.0. Now, with the massive 4.0 release, the engine has split from the SFC to form its own dedicated foundation.
I have to admit, I love how loud and hyped Godot’s update announcements are. Defold is much more humble. For instance, in 2020, Defold quietly released Vulkan renderer support as an extension for developers who really needed it, barely making a sound about it. They did the exact same thing with PBR, bullet physics, and glTF support. While hyping features generates excitement, comparing marketing strategies won’t help you code your game.
What programming languages do they use?
The programming language is the most glaring difference between the two engines.
Godot and GDScript
Godot relies on its own custom language called GDScript. It looks and feels very similar to Python and received massive upgrades in version 4.0. GDScript is fairly easy to pick up, though absolute beginners with zero programming background might struggle initially. The biggest downside? You cannot use GDScript anywhere outside of Godot. I once spent months mastering GDScript, only to realize none of that specific syntax transferred over when I tried jumping into a Unity project.
Defold and Lua
Defold, on the other hand, uses Lua—a highly popular scripting language also used in CryEngine, Lumberyard, and Solar2D. Lua is incredibly lightweight, blindingly fast, and very easy to learn, making it a fantastic starting point for beginners.
Other language options
Both engines technically support other languages, but since they weren’t explicitly designed around them, you should treat them strictly as secondary options:
- Defold: Supports C++ via official native extensions, plus community-driven support for TypeScript, Haxe, and C#.
- Godot: Supports C++ and C# via official GDNative bindings, alongside community support for Rust, Haskell, and Clojure. Godot used to feature visual scripting, but they completely ripped it out in version 4.0.
2D and 3D development
Defold’s bread and butter is 2D game development. If you want to build a 2D game, it is an absolutely stellar choice.
Godot pushes much harder into the 3D development space, though it still packs a phenomenal toolset for 2D games. It is the more versatile engine if you plan to jump between different genres.
Graphics API support
Both engines fully support OpenGL, OpenGL ES 2 and 3, and WebGL. Defold has had an official extension for Vulkan since 2020, while Godot finally baked Vulkan rendering directly into its 4.0 release. For iOS games, which strictly require Metal support, Defold uses MoltenVK, while Godot relies on ANGLE.
3D features of Godot 4.0
The 4.0 update brought a massive arsenal of built-in 3D features:
- Advanced lighting systems, including signed distance field and voxel global illumination
- Heavily upgraded shadows
- Screen space ambient occlusion
- Multi-sample anti-aliasing (Defold doesn’t have this out of the box, though the community built a workaround)
- Volumetric fog and sky shaders
Defold has always maintained a “bare-bones” philosophy, giving developers the absolute freedom to build and attach exactly what they need. Godot takes the opposite approach, constantly stuffing the engine with ready-to-use features. This comes at a cost, which we will cover shortly. It is also worth noting that Godot is a massive project with over 2,000 contributors, whereas Defold relies on a tiny core team and a handful of dedicated community contributors.
Platform support comparison
Defold
- Windows, Linux, and Mac desktop platforms
- Android, iOS, and KaiOS (specifically targeting extremely low-end devices)
- HTML5 and Facebook games
- Nintendo Switch
- PlayStation 4 and 5 support is coming very soon
The Defold editor runs natively on Windows, Mac, and Linux.
Godot
- Windows, Linux, and Mac
- Android, iOS, and HTML5
- Console publishing is available, but you usually have to go through third-party commercial companies managed by core Godot contributors.
- Godot 4.0 finally introduced the ability to compile directly for VR and AR platforms.
The Godot editor also runs on Windows, Mac, and Linux. Since version 3.5, they even offer web and Android versions of the editor itself.
A quick warning here: my first experience running Godot 4.0 on Windows was incredibly buggy. The editor crashed on me twice while just trying to import a basic 3D model. If you need stability right now, sticking with version 3.5.1 is the safer bet.
Performance and update cycles
Performance
Defold is legendary for its blazing-fast rendering speeds and incredibly low memory footprint. If you are building games for mobile devices or web browsers and need them to run silky smooth on older hardware, Defold is the undisputed champion.
Godot is fast enough for the vast majority of projects, but it hogs significantly more memory than Defold. If you are targeting low-end devices, that memory overhead will absolutely tank your frame rates. Version 4.0 aims to fix this, but its real-world performance in shipped games is still largely untested. Furthermore, despite being labeled a “stable” release, 4.0 is currently packed with nasty bugs and technical glitches that will take months to iron out.
Update cycles
- Godot: They do not announce release dates in advance. The community constantly jokes about “Waiting for Godot” (a nod to the Samuel Beckett play that inspired the engine’s name) because you never know when the next update will drop.
- Defold: Updates roll out like clockwork every single month, preceded by a strict two-week public beta. Because the updates are frequent, the changes are smaller and less flashy. However, their primary focus has always been proving to developers that Defold is an unshakeable, reliable tool for professional development.
Tools and editor workflow
Both engines supply a massive suite of tools to streamline development, including physics engines, tile map editors, particle effect systems, and robust third-party library support.
- Defold: The editor is clean, straightforward, and highly accessible. You can customize it using CSS and expand its functionality with editor scripts. Because it strips away the bloat, you might find it lacking some highly advanced, niche features.
- Godot: The editor is significantly more complex. It can easily overwhelm a beginner, but that sheer density of features makes it vastly superior for handling incredibly complex, large-scale projects.
Game size and mobile development
Because Godot is stuffed with so many built-in features, its exported game files are noticeably larger than Defold’s. Defold allows you to export incredibly tiny, lightning-fast web games, making it the perfect tool for platforms like Facebook Instant Games or the KaiOS market in India.
Defold’s obsessive focus on mobile and web development gives it massive advantages:
- Incredibly small game sizes and UI systems that adapt flawlessly to different screen resolutions.
- Rapid mobile development through a dedicated companion app and hot-reloading (you can push code changes directly to your phone without rebuilding the app).
- Official, highly maintained plugins for monetization, in-app purchases, push notifications, and analytics.
- Constantly updated SDKs to ensure compliance with the latest Android and iOS requirements.
Godot is fighting hard to compete in this space, but when compared directly, it lags severely behind in mobile optimization and high-quality plugins. I spent a week trying to get a basic ad plugin working in Godot before giving up; the same task took me twenty minutes in Defold.
Community and learning resources
Defold community
Because Defold hit the open market later, its community is much smaller than Godot’s. However, it is highly active, tight-knit, and constantly growing. They have an excellent forum, a highly responsive Discord server, and an active subreddit where developers share ideas and get direct help from the Defold team. The official website hosts a fantastic range of tutorials and in-depth documentation.
Godot community
Godot boasts a massive, deeply entrenched community, fueled by its longer history, massive feature set, aggressive marketing, and fiercely loyal fans. The community is everywhere—forums, Discord servers, and countless third-party resources. The official website is packed with extensive documentation, tutorials, and a showcase of games built with the engine. A massive bonus for Godot is its excellent built-in support for RTL (Right-to-Left) languages.
Games built with these engines
Both engines have a proven track record of shipping highly successful games.
- Godot: Primarily dominates the indie scene. There are a few rare AAA exceptions, like Sonic Colors Ultimate.
- Defold: Battle-tested across every supported platform. The massively successful mobile game Family Island is probably the most famous example.
Personal experience
The lack of certain out-of-the-box features and advanced tutorials in Defold definitely frustrates me sometimes. But honestly, the random editor bugs and the lack of low-level control in Godot frustrate me infinitely more.
For me, the decision comes down to one thing: reliability. I prefer a rock-solid foundation that gives me the absolute freedom to build exactly what I need, rather than fighting against an inflexible, pre-built system. Godot takes a completely different path. It focuses heavily on providing generic, ready-to-use features designed to fit almost any game and please the vast majority of developers. Defold just hands you the bare skeleton and trusts you to build the rest. Godot’s approach often backfires because trying to be good at everything inevitably leads to structural contradictions. Defold has a much sharper, narrower focus, and it executes it flawlessly.
Which engine should you choose?
Who should use Defold?
Defold is an absolute powerhouse for developers who want to build highly optimized 2D games, especially for mobile, web, desktop, and the Nintendo Switch:
- It is completely free and unshakeably reliable.
- The learning curve is very gentle.
- It gives you immense low-level control without sacrificing your game’s performance.
Who should use Godot?
Godot is a highly versatile engine and an excellent choice if you are leaning heavily toward 3D game development:
- It is fantastic for absolute beginners because it hands you a massive toolkit of ready-to-use features that drastically speed up development.
- There is an endless ocean of tutorials available on YouTube.
Just keep in mind that learning Godot might make it slightly harder to transition to other engines later on, because its node-based architecture and custom programming language are highly specific to Godot.
Final thoughts on Godot 4.0
The massive 4.0 update brought a highly impressive new renderer and a ton of tools for 3D development, but it is far too unstable for serious professional development right now. If you want to use Godot to ship a commercial product today, stick to version 3.5.1—it is a fantastic, battle-tested engine.
Also, remember that this was a strict comparison against Defold, which does not focus on 3D games. If you are aiming to build a high-fidelity, AAA-quality 3D game, you should not be looking at either of these; Unreal and Unity are still the undisputed kings of that specific arena.
