A Piskel alternative that’s still shipping

Piskel vs Tsubu, feature by feature

Features change. Every Piskel fact above was checked on 22 July 2026 against Piskel’s own site and repository (with the other named editors for context): Piskel · Piskel on GitHub · Pixelorama · Pixilart.

Piskel still opens — it just stopped in 2018

First, the fair part: Piskel isn’t broken. It still loads in a browser tab, it’s still free and open-source under Apache-2.0, and for quick anonymous sketches it’s lovely. But it’s frozen — the last release was v0.15.0 back in 2018, and the maintainer notes that changes are “unlikely to be reviewed or merged due to limited time.” If your only ask is a no-account sketchpad, Piskel still does that job.

“Piskel alternative” searches often surface thin directory listings, so it’s worth saying plainly: there are active online editors. Pixelorama’s web build is the most actively developed free editor (desktop or browser); Pixilart pairs a browser editor with the biggest pixel-art community; LibreSprite has a web build too. This page is for the switcher who wants more than a like-for-like editor — engine-ready export and an optional AI first pass on top of the drawing.

How to move your Piskel sprites into Tsubu

Your old work comes with you. In Piskel, export a sprite as an animated GIF or a PNG spritesheet — the formats it already gives you. In Tsubu, drop that file onto your library: a GIF becomes a stack of editable frames (Tsubu reads its per-frame delays to set the FPS), and a PNG spritesheet is sliced into frames with a live grid-overlay preview — because Piskel writes no atlas data, you set the frame size once and watch the cut line up. Either way you land back on real, editable pixels.

The muscle memory carries over too, because Tsubu is keyboard-first: B for pencil, E eraser, G fill, I eyedropper, M select-and-move, H pan, Z zoom; “[” and “]” size the brush, Ctrl+Z and Ctrl+Shift+Z undo and redo, and on an animation “,” and “.” step frames while Alt+N adds one. Hold Alt for a momentary eyedropper and Space to pan, the way you’d expect.

The upgrade Piskel never shipped: a sheet your engine can read

Piskel exports an animated GIF or a PNG spritesheet, and that’s it — there’s no JSON, so your engine still has to be told by hand where each frame sits. Tsubu exports the sheet with a JSON atlas in the familiar Aseprite / TexturePacker array shape — per-frame rectangles, durations in milliseconds and a whole-animation frame tag — zipped with the PNG and upscaled with a clean nearest-neighbor pass at 1×, 2×, 4× or 8×. It drops into Unity, Godot, Phaser and Pixi without custom glue.

To be fair about it: free web packers export engine atlases too, so the atlas by itself isn’t the differentiator. What Tsubu adds is folding draw, animate, an optional AI pass and that export into one browser loop — instead of bouncing a Piskel PNG through a separate packer just to get engine data.

An optional AI first pass — that you actually edit

Piskel is a manual editor, and plenty of people want exactly that. Tsubu keeps manual drawing front and centre and adds AI as an option you can ignore. Type “a tiny knight with a red cape”, pick 16×16 or 32×32, and it drafts a grid-true, limited-palette, transparent sprite — a strong first pass, not a finished asset — which you then finish by hand. Already have a sprite? Hand it over and the AI drafts animation frames onto the timeline for you to retouch.

It’s AI-assisted and human-refined: the model drafts, every pixel stays yours to edit, and what it drafted stays separable so you can disclose it. On training data and provenance the wider field hasn’t settled the question, and we’d rather flag that plainly than wave it away.

What you trade, and what “free” means here

Two honest trades. First, sign-in: Piskel lets you open the page and draw anonymously; Tsubu asks you to sign in with Google before you start. The upside is a cloud library that keeps every project with you between machines — but it is a real difference, and if anonymous entry is the whole point for you, that’s a fair reason to stay on Piskel. Second, layers: Piskel has a simple layers panel and Tsubu doesn’t yet, so today you work one editable image per frame.

And “free”: Tsubu is free for early adopters right now, with AI usage sponsored by the platform so there’s no per-generation credit meter. That’s a limited-time launch offer — the honest version of the word, not “free forever”. There’s no credit card; there is that Google sign-in.

Piskel

You want the simplest no-account browser sketchpad for quick sprites and don’t need engine export or active development — just know it’s been frozen at v0.15.0 since 2018.

Pixelorama

You want an actively developed free editor (layers, tilemaps, extensions) on the desktop or the web, and don’t need a hosted cloud library or AI.

Pixilart

You want a free browser editor wrapped in the largest pixel-art community, and you’re not focused on game-engine export.

Tsubu

You’re moving off Piskel and want engine-ready sheets with a JSON atlas, an optional editable AI first pass and a cloud library — and you’re fine signing in with Google and using an early-access tool.

Switching from Piskel — common questions

Is Piskel dead or discontinued?

Not exactly — Piskel still opens in your browser and stays free and open-source (Apache-2.0). But it’s frozen: its last release was v0.15.0 in 2018 and the maintainer says changes are unlikely to be reviewed or merged. It works; it just isn’t being developed anymore.

What’s the best Piskel alternative?

It depends on the job. For an actively developed free editor, Pixelorama is the strongest (desktop or web), and Pixilart pairs a browser editor with a big community. If you want engine-ready sheets with a JSON atlas, an optional editable AI first pass and a cloud library, Tsubu is a browser studio built for that switch — free for early adopters.

Can I import my Piskel sprites into Tsubu?

Yes. Export from Piskel as an animated GIF or a PNG spritesheet, then drop the file into Tsubu: a GIF becomes editable frames (Tsubu reads its delays to set the FPS) and a PNG sheet is sliced into frames with a live grid-overlay preview. Every pixel is editable again.

Does Tsubu need an account, since Piskel doesn’t?

Yes — Tsubu asks for a Google sign-in, where Piskel lets you draw anonymously. That’s a real difference. The trade is a cloud library that keeps your work across machines, and there’s no credit card involved.

Is Tsubu really free?

It’s free for early adopters for a limited time, with AI usage sponsored so there’s no per-generation credit cap. It’s a launch-window offer, not free forever — and there’s no credit card, just a Google sign-in.
