itch.io brings Flash games back to the browser with the open-source Ruffle emulator

Flash games have a home again on itch.io. The indie game store has rebuilt its Flash support around Ruffle, an open-source emulator that runs entirely inside the web browser, so titles that once needed the Flash plugin can be played on the site with no extra software.

The change was announced by itch.io founder leafo in a developer update titled “The return of Flash games”. Users had requested it a few times over the years, he wrote, and testing showed Ruffle’s compatibility to be quite good.

Nothing to do for developers

Creators who already host Flash projects on itch.io do not need to touch them. The site has swapped its old embed code for a new player frame that loads each .swf file with a recent Ruffle build, dated November 3, 2026 at the time of the announcement. The same applies to fresh uploads, so developers sitting on a pile of unreleased Flash games can publish them now.

There are limits. Games protected with site-locks, which only allow a file to run on specific domains, may need extra work, and itch.io is asking players to report titles that refuse to start. The store also has a dedicated page that lists all of its Flash games.

Ruffle is maturing

The timing fits Ruffle’s own progress. In a blog post published on November 4, the project’s team said Ruffle now offers stable releases, currently version 0.7.1, alongside its nightly builds. By its own measure, it supports 99% of the ActionScript 1/2 language used by older Flash titles, and 82% of the ActionScript 3 API, with most games already playable with few problems.

Since its previous progress report more than two years ago, the team has merged 2,329 pull requests from 92 contributors, and an iOS app is in the works.
