Professional-ready sketch and painting software with animation capabilities.

For user from PaintTool SAI, Adobe Photoshop, MediBang Paint, ibis Paint X, or SketchBook, this software have anything you need.

If you're Clip Studio Paint user, it lacks a lot of unique feature that CSP have. (Especially if you come from professional Japanese manga/animation production pipeline). Potential CSP features addition such as comic creation utilities (both book and webtoon layout) and sub-tooling are still in dicussion. Krita also does not have flexible windowing system to work on multiple artwork (I already made feature request for this).

For Expresii and Rebelle users, there's no realistic water paint emulation yet.

For openCanvas user, go use Clip Studio Paint instead (for now, it's paid tho).

Alternative to Live2D Cubism software suite, for creating live animated character, the one that usually featured in Japanese visual novel (especially galge) and Virtual Youtuber.

Still not as capable to match existing industry standard (still in early development stage). Only recommended if you're merely using it for indie games or Vtuber character.

They also have active Japanese contributors, so it might not too far from what Japanese ACG industry needs.

The dev recently changed their software from free to freemium, as they want to fund the development. It cost 20USD, but you can still "evaluate" it for free with 10 seconds reminder screen at startup.

Image editor software. If you ever tried GIMP five or ten years ago, it might be the best time to revisit GIMP, as it has tons of improvement.

While the software itself is powerful, it requires a little bit of learning, especially if you're coming from Adobe Photoshop, Affinity Photo, or Pixelmator.

GIMP 3.0 forward brings a lot of new features and improvement, after more than 10 years of fixing underlying base to be more future proof. Notably: shape tools.

List of supported image format: https://testing.developer.gimp.org/core/standards/images/ (incomplete?)

Pixel art creation software. Also suitable to create sprite, game asset, or pixel animation. Good alternative to paid software like Aseprite.

It's not 1-to-1 feature parity, but it has a lot of unique features.

Animation creation software. Specialized for Japanese 2D anime industry pipeline. Used by Studio Ghibli.

It lacks a lot of QoL improvements you expect from 2D modern animation software. Its fork: Tahoma2D tried to fix this.

3D creation software suites. Also capable to do video editor and 2D animation, though not as powerful as other specialized software.

It might not be the software used in (several) already established animation, movie, or game development (looking at you, Autodesk Maya), but it become the new standard for newer studio as they are able to start a new production pipeline.

Vector-based document/image creation software with (sometimes) better feature implementation than existing proprietary alternative. Easy to pick up and learn.

Choose this over Adobe Illustrator if you're beginner. To note: Affinity Designer has several unique feature that even any industry standard don't have (I think), but the dev also seems keen to replicate some features from it and other competitor.

Node-based raster and vector software. Built as multi-platform (including web) with Rust. Currently in alpha.

This developer is attempting to make software caters to graphic design, motion graphics, image editing, digital painting, VFX compositing, page layout and printing.

Roadmap: https://graphite.rs/features/#roadmap

General motion graphic and web animation software. Fork of discontinued enve with active contribution and modern UI.

User interface (UI) designer software with collaboration feature. Alternative to Figma and Sketch

Desktop publishing software. Good enough for professional usage, but lacking a lot of modern feature and user experience compared to alternative like Adobe InDesign or Affinity Publisher

If you just want to replace Microsoft Publisher, that might be enough.

Advanced voxel creation software. Alternative of Avoyd and Qubicle Voxel Editor

Basic voxel creation software. MagicaVoxel alternative.

Just like MagicaVoxel, this one is relatively easy to use that even children can use it like a toy.

Though, MV has better interface, and it's also free (though not open source) ...

Basic image editing utility.

Originally clone of Paint.NET, now evolved into more modern version.

Collaborative drawing software.

It's suitable for professional tools or community drawing.

Roadmap: https://media.ccc.de/v/lgm25-upstream-2025-83646-state-of-libre-graphics (LGM 2025 event, minute 09:44)

General purpose graphic software, combining raster, vector, and pixel art with node graph support.

Not as powerful as Pixel Composer yet in terms of pixel art node graph. Might be a close competitor to PixelOver as well (?)

Vector animation and motion design desktop application, with LottieFiles format support.

Oriedita is a computer program used for drawing origami crease patterns. It comes with a wide range of tools to help you draw crease patterns.

Alternative to SketchBook

In my opinion, this software can be developed to be more of Rebelle and Expresii , as it has user interface that serve similar audience.

Work in progress.

The developer is inspired from PaintTool SAI and MediBang Paint

PaintTool SAI clone for Linux.

If Krita and GIMP feels too bloated, while MyPaint is too basic, use this one.

Node-based painting tools with experimental UI.

Simple and distraction free storyboarding software.

Lightweight online drawing tools, can be self-hosted.

General 3D CAD software.

I don't really use other commercial alternative, so I cannot properly compare them. But it definitely works for various task, from architecture, machinery, to 3D printing.

Defintiely not a one-to-one SketchUp alternative, as this software has more extensive interface and tools.

Intended for "planar slice 2D cut" stuff (I don't know whether there's actual term for it).

LibreCAD is an open source 2D CAD application for Windows, Apple and Linux. It is based on Qt, which is a leading cross-platform application and UI development framework.

KiCad is an open source software suite for electronic design automation (EDA) - designing schematics of electronic circuits and printed circuit boards (PCB). KiCad is developed by Jean-Pierre Charras. And features an integrated environment between schematic capture, bill of...

Advanced digital photo management software with features to organize, tag, compare, and process photo collections, supporting multiple formats including RAW.

Powerful cross-platform raw photo processing software offering advanced user control over demosaicing and development. Supports HDR DNGs and image formats.

Open source non-destructive RAW photo editor and image database with lighttable and darkroom views, real-time editing, HDR and scientific image support.

VOCALOID alternative, but don't expect the same voicebank, like Hatsune Miku or Po-uta.

Just in case you don't know what is Vocaloid, it's basically a voice synthetizer software.

There's also another FOSS voice sythetizer (talk only, no singing) called VOICEVOX. This one is Japanese only, but it has popular Zundamon official voice bank! https://github.com/VOICEVOX/voicevox

Powerful subtitling software, used by amateur and professional. Probably the most used software in fansubbing scene. Some company like Crunchyroll or Muse Asia are actually using this software.

Powerful video editor with KDE principles: "Simple by Default, Powerful when Needed"

Use this instead of pirating Wondershare Filmora. I know some of you do. Yes, some my friends did this all the time and ended downloading trojan.

Basic video editor, akin to Windows Movie Maker.

Free, open-source video editing with multi-format timelines, frame accurate seeking, and robust capture support up to 4k for diverse projects.

Free cross-platform DAW supporting VST plugins, MIDI, and lossless audio. Offers music loopers and sequencers with privacy, no ads, and offline capability.

Mixxx integrates the tools DJs need to perform creative live mixes with digital music files.

Simple and distraction free image viewer. Great zooming approach, similar to good old Picasa Image Viewer.

Reference manager app. PureRef alternative.

Krita has this feature built-in, but not as comprehensive as PureRef.

Ever tired managing art upload to many various sites? This software (might be) your solution.

Supports various sites, from X, DeviantArt, pixiv, Bluesky, and so on. Fediverse instances such as Mastodon, Misskey, Pixelfed, and Pleroma also supported.

There's new rewrite on https://github.com/mvdicarlo/postybirb-plus

Weylus turns your tablet or smart phone into a graphic tablet/touch screen for your computer.
