Is there a Deltarune browser port?
Short answer
Not realNo. As of 13 Nov 2026 there is no real Deltarune browser port: Toby Fox has never released one. Itch.io pages titled "Deltarune webport", some for Chapters 3 and 4, re-upload the game without permission, and one says it was made for school game portals. Deltarune's browser boss-fight games are fan games. The official game is sold for PC and consoles.

What are the Deltarune browser boss fights?
Deltarune boss-fight browser games are fan projects. Fans recreate single fights, such as well-known bosses from the chapters, in browser engines. They can be fun, but they aren’t the game, and quality varies. Fan engine recreations on GitHub aim to rebuild Deltarune’s engine, not to ship the game.
Why do Deltarune browser sites keep appearing?
Deltarune webports spread on game portals aimed at school computers for school computers; one uploader says that was the reason for the copy. New chapters bring a rush of re-uploads. A copy can be changed by anyone, and nobody checks what else it loads.
What can I play instead in a browser?
Undertale, Toby Fox’s earlier game, has no browser version either: see our page on Undertale in a browser. Our list of games you can play in a browser covers official and fan web ports we’ve checked.
How do I avoid fake Deltarune downloads?
