Piskel is an open source editor that runs in the browser, with layers, animation and a public gallery. Development has stopped, but it still works and is a common first editor.

Bfxr adds new waveforms, filters and a mixer to the sfxr formula, and runs in the browser.

sfxr generates jump, laser, explosion and pickup sounds with one click, then lets you tweak the synth parameters. Every later sound effect generator descends from it.

DragonBones was one of the first 2D skeletal animation tools, and for years the free alternative to Spine, with runtimes for the major engines and an export format several of them read directly. Development stopped some years ago, but the editor still runs and the runtimes are still around.

FamiTracker writes music for the NES sound chip and its expansions, and exports NSF files that play on real hardware. Community forks (0CC, Dn) continue its development.

A simple open source editor for the Mac with layers and a clean toolset.

SpriteStack is a voxel editor that renders its models as pixel art sprite stacks and rotations, for games that fake 3D with sprites.

An open source editor made to be simple and easy to use, with slice editing and model export.

Sprytile is a Blender add-on for building low-poly scenes by painting with a tilesheet: pick a tile, draw on a grid in the 3D view, and it makes the geometry and maps the texture as you go. It suits the tile-textured look of early 3D games.

An open source voxel editor written in Java, with layers, animation rigging and export to many formats.
