Software for Web Browser

picoCAD builds small low-poly models out of a handful of shapes and textures them with a single tiny texture sheet, in a deliberately constrained toolset. Models and turntable renders export straight out of it.

lvllvl is a browser editor for character-based art. It covers PETSCII and a long list of other machines' character sets, with layers, animation frames, custom tilesets and palettes, and it can generate frames from an uploaded image or video. Projects save to the browser, to GitHub or to Google Drive.

Godot has a dedicated 2D renderer with pixel-snapping, nearest neighbour filtering and viewport scaling options that make low-resolution games straightforward.

Blockbench is a free and open source editor for low-poly models with pixel art textures. Models can be exported into standard 3D formats, to be shared, rendered, 3D-printed, or used in game engines or games line Minecraft. Modeling, UV mapping, texturing with pixel-art tools, rigging and animating, can all be done in the program.

Blockbench has a clean and beginner friendly interface, but also offers lots of customization and advanced features for experienced 3D artists. Plugins can extend the functionality of the program even further.

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.

Pixelorama is a full featured free editor: layers, animation with onion skinning, tile mode, palettes, and an active development pace. It runs on every desktop platform and in the browser.

PICO-8 bundles a code editor, sprite editor, map editor, sound effect editor and tracker into one tiny virtual machine with strict limits that keep games small and finishable.

BitFontMaker2 is a bitmap font editor that runs in a browser: draw each character on a small grid, set the widths, and download a TrueType file. It has been around a long time and stayed simple, which is why it is still the quickest way to get a pixel font out of an idea.

Novaboard runs in the browser and as a desktop app, with layers, animation and effects.

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

Bitsy is a tiny editor for making small worlds: a few rooms of 8x8 tiles, an avatar that walks around them, and short conversations with the things in them. The limits are the point - there is no scripting to speak of and two colours at a time - and a finished game is a single HTML file.

ChipTone builds sound effects from layered oscillators, envelopes and effects with a lot more control than an sfxr style generator.

PuzzleScript is a browser engine where an entire puzzle game is a short text file: a legend of characters, a set of rewrite rules, and the levels drawn as ASCII. Games run and share as a single link, which has made it the usual home for small tile-based puzzle experiments.

TIC-80 is an open source fantasy console in the PICO-8 mould with a larger screen, several scripting languages, and built-in sprite, map, sound and music editors.

LibreSprite continues the last GPL version of Aseprite as a community project. It keeps the familiar layers, animation timeline and palette tools, and adds its own scripting and a browser build.

A basic web-based editor made to be simple and intuitive, which can load any palette from the Lospec palette list. It is no longer in development and may contain bugs.

ASCIIFlow is a browser scratchpad for drawing boxes, arrows and labels in plain ASCII, for diagrams that have to live inside a comment or a text file. There is nothing to install and nothing to sign into.
