Best Level Design Software for Indie Devs 2026
The best level design software for indie 2D developers splits into two camps: dedicated level editors that export to any engine, and the tile and room editors built into your engine. For dedicated editing, LDtk and Tiled are the standards — LDtk is the modern, entity-driven editor built by the lead designer of Dead Cells, and Tiled is the long-standing tile-map interchange format nearly every 2D engine can read. If you would rather stay inside your engine, Godot's TileMapLayer, Unity's Tilemap, GameMaker's Room Editor, and Construct 3 each ship a capable built-in editor. This guide ranks the serious options for 2026, compares licenses and export formats, and is honest about when a dedicated editor beats an engine-native one — and where a 2D-first IDE like Egmatic fits if you want the level editor and the engine in one tool.

The right choice depends less on which is "best" than on whether you want a separate editor or one that shares a toolchain with your game.
This list covers software whose primary job is building 2D levels — dedicated level editors and the tile/room editors inside 2D engines. For engines and frameworks themselves, see the 2D game frameworks comparison and the engine choice guide; for the principles you apply once you have a tool, see the 2D platformer level design guide.
The dedicated 2D level editors
A dedicated level editor is a standalone tool that exports level data — usually JSON, XML, or TMX — for your engine to load. Its strength is engine-agnosticism: you can change engines and keep your levels. Its cost is integration: you write the loader.
| Tool | License | Exports | Made famous by |
|---|---|---|---|
| LDtk | MIT (free) | JSON (.ldtk), TMX, PNG | The Dead Cells designer's modern pick |
| Tiled | GPL-2.0+ / BSD | TMX, TSX (XML) | The 2D tile-map standard |
| Ogmo Editor 3 | MIT (free) | JSON, XML | Celeste, TowerFall |
LDtk — the modern entity editor
LDtk is a free, open-source 2D level editor under the MIT license, created by Sébastien Bénard — lead designer of Dead Cells and a co-founder of Motion Twin. Its defining choice is to be entity-driven: you define entities, layers, and fields in a clean UI, and it saves a JSON project you read directly. Compared with a tile editor, that makes it strong for levels full of placed objects, triggers, and metadata rather than pure tile art. It can also export TMX and PNG, and its multi-file mode keeps parsing fast even on large projects. If you want a dedicated editor that feels designed in the 2020s, LDtk is the one to start with.
Tiled — the tile-map standard
Tiled is the free, open-source tile-map editor maintained by Thorbjørn Lindeijer, and it is the closest thing 2D games have to an interchange standard. It saves maps as TMX and tilesets as TSX, both XML, and almost every 2D engine and framework — Unity, Godot, GameMaker, libGDX, Phaser, MonoGame — has a library to read them. The editor itself is GPL-2.0+, while the TMX format and its libraries are BSD-licensed, which is why adoption is so broad. Its strength is tiles: if your levels are large tile maps, Tiled's layers, terrains, and Wang tiles are hard to beat. Its weakness is entities — placed objects are supported but feel like an afterthought next to LDtk.
Ogmo Editor 3 — the editor behind Celeste
Ogmo Editor 3 is a free, open-source 2D level and tilemap editor, maintained as a Community Edition written in Haxe under the MIT license. The original Ogmo was created by Maddy Thorson and Noel Berry, the team behind Celeste and TowerFall, and it was used to build Celeste's levels. Each project is defined by a human-editable .ogmo config, which makes it portable and scriptable. Ogmo is loved by a devoted niche, but it is less actively developed than LDtk and Tiled, so treat it as a capable tool with a smaller ecosystem.
The engine-native level editors
Most 2D engines ship their own level editor. The upside is zero integration: the editor speaks the engine's format natively. The downside is lock-in: your levels live in that engine.
| Engine | Editor | License | Built in? |
|---|---|---|---|
| Godot | TileMapLayer (was TileMap) | MIT (free) | Yes |
| Unity | Tilemap + Rule Tiles | Free tier available | Yes |
| GameMaker | Room Editor | Free non-commercial; $99.99 commercial | Yes |
| Construct 3 | Layout + Tilemap | Subscription (browser) | Yes |
Godot — TileMapLayer
Godot is a free, open-source MIT engine, and its 2D level editing centers on the tile system. As of Godot 4.3 the old TileMap node is deprecated in favor of TileMapLayer — one layer per node — with a built-in converter for existing projects. The editor handles tiles, terrains, and painted collisions well, and because Godot is fully free with no royalties, there is no commercial ceiling. The trade-off is that levels are Godot scenes; moving them to another engine is manual.
Unity — Tilemap with Rule Tiles
Unity ships a built-in 2D Tilemap with a Tilemap Collider 2D and a Composite Collider 2D that merges per-tile colliders into one continuous shape. Rule Tiles, which pick a sprite automatically based on neighboring tiles, come from the open-source 2D Tilemap Extras package. On Unity's free Personal tier this is all available; the catch is Unity's license terms and the wider complexity of the engine. For a deeper engine comparison, see MonoGame vs Unity vs Godot.
GameMaker — Room Editor
GameMaker's Room Editor organizes a level into layers — tile layers, instance layers, background layers, asset layers, and path layers — and it is where most GameMaker games are built. It is capable and tightly integrated. The cost model changed in late 2023: the engine is free for non-commercial use and a one-time $99.99 for a commercial license, which is simpler than a subscription.
Construct 3 — layout editor in the browser
Construct 3, made by Scirra, runs entirely in the browser and pairs a layout and tilemap editor with an event-sheet logic system that needs no code. Its free tier is limited (50 events, two layers, no desktop or mobile export); the Personal tier is around $129.99 a year and unlocks the export targets. It is the fastest route from zero to a playable 2D game if you do not want to program, and your levels are Construct layouts.
How to pick by your situation
- You want the best dedicated editor, full stop → LDtk. Modern, MIT, JSON, and the entity model suits real game levels.
- Your levels are mostly tiles → Tiled. The terrain and Wang-tile tooling is unmatched for pure tile art.
- You are already in an engine → use its built-in editor. Godot TileMapLayer, Unity Tilemap, or the GameMaker Room Editor need no loader.
- You want to change engines without losing levels → LDtk or Tiled, because their export formats outlive any single engine. The JSON in game development guide shows how a data-driven engine consumes such exports.
- You do not want to code at all → Construct 3, whose event sheets and layout editor are built for that.
Common mistakes
| Mistake | What goes wrong | What to do instead |
|---|---|---|
| Picking a tile editor for object-heavy levels | You fight the tool to place triggers and entities | Use an entity editor like LDtk for object-driven levels |
| Ignoring the export format | Your engine cannot read the levels | Check the format (JSON, TMX) before you commit |
| Overlooking the license | You discover commercial limits late | Know GPL vs MIT, and any revenue caps, up front |
| Building a loader you do not need | You integrate Tiled into an engine with a fine native editor | Use the engine's built-in editor unless you need portability |
| Locking levels into one engine | A future engine switch means rebuilding levels | Keep levels in LDtk or Tiled if portability matters |
Where Egmatic fits
Most readers searching "level design software" do not want to bolt a separate editor onto an engine and maintain a loader. They want the level editor and the engine in one tool, with a fast preview loop. Egmatic is built for exactly that: a 2D-first IDE and engine whose scene editor is the level editor, with live preview so you can nudge a platform, run the level, and feel the change in seconds. Because level data is authored as structured data, the same editor feeds the engine that runs it — no export step, no loader to maintain. If your goal is to finish a 2D game rather than to assemble a toolchain, that is the shorter path.
The bottom line
For dedicated 2D level editing, LDtk is the modern, entity-driven choice and Tiled is the tile-map standard; Ogmo Editor 3 is capable but more niche. If you would rather build inside your engine, Godot's TileMapLayer, Unity's Tilemap, GameMaker's Room Editor, and Construct 3 each ship a solid built-in editor. Pick by whether you want portability across engines (dedicated editor) or zero integration (engine-native), check the license and export format before you commit, and remember that a 2D-first IDE like Egmatic can put the level editor and the engine in a single tool.
