Ogmo – free, open source, 2D level editor
ogmo-editor-3.github.ioThere's also LDtk. By the director of Dead Cells. https://ldtk.io/
LDtk does not work for isometric though
How does it compare with Tiled? https://www.mapeditor.org/
I've used Tiled but not used Ogmo, but reading the bulletpoints the main upsides seems to be a more project focused approach (perhaps enabling more direct loading), in general though it doesn't seem to be too different (most listed features are in Tiled).
If you're starting fresh maybe try both before integrating on a coded workflow, but either will probably serve just fine for 2d games.
Was about to asked but you were faster.
Several level editors mentioned in this article: https://noelberry.ca/posts/making_games_in_2025/

Yeah, that's where I found this one, and it looks awesome, so I thought it deserved its own post :)
I always feel depressed when I see what is my developer work nowadays, but this kind of project makes me happy. I don't know exactly what it is, but those simple UI thingies with pixels are cozy to me.
Ah this is an old project and hasn’t seen any updates in years which is why what I was going to comment is what it is
Looks pretty cool! I’m looking around the docs to find some import instructions for a common engine.
Hey, a reference to Jumper! Glad to hear that Maddy Thorson hasn't forgotten her roots.
Easy Integration - When you're done editing, save your level to a handy JSON file - one that is easily parsed to give you immediate access to all of the tiles, decals, and entities you've authored!
That still leaves a lot to be desired. Am I expected to write all the code to import this format into my engine of choice? That's not exactly "easy".
For instance, is there tooling to import into GameMaker? That would seem to be table stakes.
