The 14 tools, reviewed
#1 Defold
Free 2D and 3D engine with Lua scripting · Sweden · defold.com
Free forever Lua scripting Console export
Defold earns first place by removing every cost question. The Defold License, derived from Apache 2.0, lets you commercialize games built with it, and the foundation behind it is registered in Stockholm with objectives its founder cannot later change.
- Pricing: Free. Free, with no up-front cost, licensing cost, royalty or runtime fee, according to the Defold site. Free plan: free plan.
- Best for: 2D and mobile studios
- Strengths: Visual scene editor; Tilemap editor; ParticleFX editor.
Where it falls short
Lua is the only scripting language, so C# or TypeScript teams must adapt.
Wrong for
A team that wants a large asset store or a heavy 3D open world with cinematic tooling.

#2 Godot
MIT licensed 2D and 3D engine run by a foundation · Netherlands · godotengine.org
Open source 2D and 3D Foundation-governed
Godot is the open engine that a studio can adopt without a lawyer. The MIT license lets you distribute changed or unchanged versions, and the license page states that Godot's terms and copyright do not apply to the content you create, so your game keeps its own license.
- Pricing: Free (MIT). Free under the MIT license; the engine's terms do not apply to games made with it. Free plan: open source.
- Best for: Indies wanting an open engine
- Strengths: Node and scene system; GDScript; C# support.
Where it falls short
Console export is not built in: the site says consoles work through third-party publishers, which adds a cost and a dependency. C# does not run on web exports in Godot 4.
Wrong for
A team shipping a high-fidelity 3D game to PlayStation and Xbox on a fixed date, which needs first-party console tooling today.

#3 GDevelop
No-code 2D game maker with an open-source editor · France · gdevelop.io
No-code events Open source editor Cloud publishing
GDevelop turns game logic into readable event lists, so a classroom or a first-time maker gets to a playable build without writing code. The editor and engine are MIT licensed, and the free plan covers a full game with limits on cloud projects and daily publishing.
- Pricing: Open source + paid tiers. Free plan. Free plan: free plan.
- Best for: Beginners and educators
- Strengths: Event-based logic; JavaScript extensions; Mobile app.
Where it falls short
Event-based logic gets harder to manage in large projects, and heavy 3D work is outside its scope.
Wrong for
A studio planning a complex 3D game with a programming-heavy team.

#4 Unity
Commercial engine for 2D, 3D and mobile games · United States · unity.com
Mobile Console export Large asset store
Unity remains the engine most mobile studios already know, with the biggest hiring pool for C# developers and exports to more than 25 platforms. Personal is free for businesses with up to $200,000 in revenue and funding, and splash screens are optional in Unity 6.
- Pricing: Per seat / year. Personal is free up to $200K revenue and funding. Free plan: free plan.
- Best for: Mobile and console teams
- Strengths: Personal, Pro and Enterprise plans; Build for 25+ platforms; Game console export on Pro.
Where it falls short
Terms have shifted before, and the vendor's own pricing page still carries a pricing-changes notice, so cost planning needs a recheck each year.
Wrong for
A cost-sensitive team that wants a source-available engine it can fork and a license that stays fixed.
Visit Unity →
#5 Unreal Engine
High-end 3D engine from Epic Games · United States · unrealengine.com
High-end 3D Royalty model Console export
Unreal is the choice when a game's selling point is visual fidelity and a team has the hardware and the programmers to feed it.
- Pricing: Royalty. Free to download; 5% royalty on lifetime gross revenue above $1 million per product, per Epic's license FAQ. Free plan: free plan.
- Best for: High-fidelity 3D studios
- Strengths: Real-time 3D renderer; Blueprint visual scripting; C++ scripting.

#6 Stride
Open-source C# engine for 2D, 3D and VR · United States · stride3d.net
C# and .NET MIT license VR ready
Stride gives .NET developers an engine where scripts are plain C# and the source is MIT licensed on GitHub. The 4.4 release, announced on 9 October 2026, rewrote the Vulkan and Direct3D 12 back ends, added a new shader compiler and a command line tool, and brought Native AOT.
- Pricing: Free (MIT). Free under the MIT license; funded by donations through Open Collective and sponsors. Free plan: open source.
- Best for: C# and .NET teams
- Strengths: C# 14 on .NET 10; Vulkan and Direct3D 12 rendering; Asset toolchain.
Where it falls short
The community and the asset market are small beside Unity or Godot, and learning material is thinner. The homepage states desktop and VR targets, so mobile and console routes need extra work.
Wrong for
A team shipping on consoles or phones next quarter.

#7 Construct 3
Browser-based no-code 2D game editor · United Kingdom · construct.net
No-code 2D Browser based No royalties
Construct 3 runs in a browser tab and builds a game from event sheets, with JavaScript available for deeper logic. Scirra states that every plan has zero royalties on anything created, and the startup plan covers registered businesses under $50,000 revenue, $100,000 assets and three employees.
- Pricing: Subscription. Free edition with limited events. Free plan: free plan.
- Best for: Web and 2D game makers
- Strengths: Event sheet editor; JavaScript scripting; HTML5 export.
Where it falls short
The free edition allows only 50 events, or 25 as a guest, which stops anything beyond a prototype.
Wrong for
A studio building a 3D action game or an open-world title.

#8 GameMaker
2D game engine with GML scripting · Norway · gamemaker.io
2D focused One-time license GML scripting
GameMaker's price shape is simple: use it free for non-commercial work, pay $99.99 once to sell a game, and take the Enterprise subscription only when you need console export or source access. The vendor states there is no watermark or splash screen on any tier.
- Pricing: One-time + subscription. Free for non-commercial use; Professional is a one-time $99.99; Enterprise is a subscription with console export and source access. Free plan: free plan.
- Best for: Solo 2D developers
- Strengths: GML scripting; Visual drag-and-drop; Desktop, web and mobile export.
Where it falls short
Enterprise pricing is not published on the pages we read, and console export depends on it. The engine is built for 2D, so 3D support is thin.
Wrong for
A team wanting an open license and engine source.

#9 Flax Engine
3D engine with C++, C# and visual scripting · Poland · flaxengine.com
C++ and C# Source on GitHub Royalty model
Flax suits small studios that want an Unreal-style 3D workflow without Unreal's footprint.
- Pricing: Royalty. Free for non-commercial and education; 4% royalty on earnings above $250,000 per calendar quarter; custom per-seat or flat-fee licenses. Free plan: free plan.
- Best for: Small 3D studios
- Strengths: Full source code; C++ scripting; C# scripting.
Where it falls short
The community is small, so answers and plugins are scarcer than for Unity or Unreal. The studio behind it is small too, and the engine's console story needs direct contact.
Wrong for
A solo developer who wants zero ongoing cost after launch.

#10 Bevy
Data-driven Rust game engine · United States · bevy.org
Rust ECS Code-first
Bevy is built around an ECS where components are Rust structs and systems are Rust functions, so game logic runs through a parallel scheduler. It ships 2D and 3D renderers composed through a render graph and an animation system with blending and morph targets.
- Pricing: Free (MIT or Apache 2.0). Free, with no license fees and no sales cuts; open source under MIT or Apache 2.0. Free plan: open source.
- Best for: Rust programmers
- Strengths: Entity component system; 2D renderer; 3D renderer.
Where it falls short
No scene editor is listed on the homepage, so designers and artists have no visual tool to work in unless the team builds one.
Wrong for
A mixed team of artists and designers with a deadline.
Visit Bevy →
#11 O3DE
Open-source 3D engine for studios · United States · o3de.org
Apache 2.0 High-fidelity 3D Modular Gems
O3DE is the open alternative for teams aiming at the high-fidelity 3D end of the market. The code is Apache 2.0 on GitHub, and features arrive as modular Gems, so a studio keeps only what it uses.
- Pricing: Free (Apache 2.0). Free under the Apache 2.0 license; the foundation is funded by member organizations and donations. Free plan: open source.
- Best for: Studios with graphics programmers
- Strengths: Gem catalog; Renderer built as a Gem; Multiplayer networking.
Where it falls short
Setup is demanding: building from source, understanding Gems and learning the renderer take longer than with Godot or Unity. The community is smaller and the asset ecosystem thinner.
Wrong for
A team of three without a graphics programmer.

#12 Cocos Creator
TypeScript editor for 2D and 3D games · China · cocos.com
TypeScript 2D and 3D Mobile and web
Cocos Creator pairs a visual editor with TypeScript scripting, which suits web developers moving into games. The vendor, Xiamen Yaji, says its engine has more than 1.7 million developers and describes a double headquarters in Xiamen and Beijing.
- Pricing: Free + paid support. Free to download; professional support and customization are sold separately. Free plan: free plan.
- Best for: Web and mobile game studios
- Strengths: All-in-one editor; TypeScript scripting; 2D and 3D.
Where it falls short
We read no license terms on the pages we fetched, so royalty or commercial limits are unverified. The vendor is based in China, which some publishers vet separately for data handling.
Wrong for
A European studio that must show licensing terms and data handling to a publisher in writing.

#13 RPG Maker
Maker tool for 2D role-playing games · Japan · rpgmakerweb.com
RPG only Plugins One-time purchase
RPG Maker covers a narrow genre and does it quickly: maps, characters, battles and an event system arrive prepared, and plugins written in JavaScript extend them. The vendor states that games made with it, including the bundled assets, can be published as freeware or commercial titles with no additional commercial license.
- Pricing: One-time purchase. Sold per version as a one-time purchase; the amounts were not read from a server-rendered page. Free plan: none.
- Best for: First-time RPG makers
- Strengths: Map editor; Database editor; Event system.
Where it falls short
The genre is fixed, so a platformer or a first-person game fights the tool. Visuals are tile-based, and the default look is recognizable.
Wrong for
A studio building anything but a turn-based or top-down role-playing game.
Visit RPG Maker →
#14 CryEngine
High-fidelity 3D engine from Crytek · Germany · cryengine.com
Full source Real-time lighting Royalty model
CryEngine offers real-time global illumination and a physically based workflow, and the full source code is available with every feature and platform. The vendor's license is free to start: a 5% royalty applies when a project ships, and the first $5,000 per project each year is exempt.
- Pricing: Royalty. Free to use. Free plan: free plan.
- Best for: Studios with graphics expertise
- Strengths: Sandbox editor; Real-time global illumination; PBR workflow.
Where it falls short
The newest news item on the pages we read dates from September 2024, which suggests a slower cadence than competitors.
Wrong for
A small team that wants frequent updates and a large community.

Questions and answers
What is the best game engine in 2026?
Defold ranks first of 14, best for 2D and mobile studios. Godot is second (indies wanting an open engine) and GDevelop third (beginners and educators). Places 1 to 3 go to challengers, vendors outside the best-known brands, wherever the category has them.
Which game engine is free for commercial games?
Godot, Stride, Bevy and O3DE are open source, so you can ship commercial games without paying anyone. Defold states no up-front cost, licensing cost, royalties or runtime fee.
Is Unity still worth using after its pricing changes?
Unity remains a reasonable choice for mobile and console teams, with Personal free below $200K and Pro at $2,310 a year per seat.
Godot or Unity for a small indie team?
Godot suits teams that want zero license cost, a small download and full source. Its 2D tooling is a dedicated renderer, and GDScript is quick to learn.
What does Unreal Engine cost?
Unreal itself is free to download. Epic's license charges 5% of lifetime gross revenue above the first $1 million per product, reported quarterly, and revenue processed through the Epic Games Store is excluded from that calculation.
Which engine is best for a first game with no coding?
GDevelop and Construct 3 both let you build with event logic instead of code, and RPG Maker does it for role-playing games. GDevelop has a free plan with a mobile app and open-source editor.
Can I move a project from one engine to another?
Art and audio move easily, since they live in standard file formats. Scenes, scripts and event sheets do not. Moving from Unity to Godot, for example, means re-creating scenes and rewriting C# or converting it to GDScript.
Do I need to pay a royalty to ship on consoles?
The engine royalty and the console platform fees are separate. Engines such as Godot, Defold and Stride charge nothing, but the console holders still require developer accounts and certification.
Which game engine is best for 2D games?
Defold, Godot, GameMaker and Construct 3 are the strongest 2D picks here. Godot has a dedicated 2D renderer with real pixel coordinates. Defold produces small builds and exports to web portals and mobile.
Is Bevy ready for commercial games?
Bevy is dual licensed under MIT and Apache 2.0, free of fees and royalties, and actively developed. It is also code only: the homepage describes an entity component system in Rust, with no scene editor listed.
How much does a European studio need to worry about vendor jurisdiction?
For most game studios the practical issue is contract terms, not location. Still, several engines are governed from Europe: Godot by a Dutch foundation, Defold by a Swedish one, plus GDevelop, Construct, Flax and CryEngine as European companies.
