Browser Technology Labels After Flash: What the Catalogue Shows

Adobe announced Flash Player’s end of life in July 2017, ended support on 31 December 2020 and began blocking Flash content from running in Flash Player on 12 January 2021. Its official end-of-life information names HTML5, WebGL and WebAssembly as open-standard alternatives.

That history does not establish how any game in this catalogue was built or whether it was migrated from Flash. The supplied metadata records current technology labels, not historical implementations.

The current 292 games have four supplied technology labels.

The four-way split

• Javascript — 152 games (52.1%)
• WebGL — 94 games (32.2%)
• Construct 3 — 45 games (15.4%)
• Construct 2 — 1 game (0.3%)

No other technology labels appear in this catalogue. That does not establish the history or continued use of other plugins elsewhere.

What these labels mean in plain terms:

Javascript is a catalogue technology label. It does not distinguish 2D canvas, DOM-based rendering or other browser APIs used by a game.

WebGL identifies a browser graphics API. The label is not a benchmark or proof that a game is 3D.

Construct 3 is an authoring-tool label. This metadata does not identify a game’s rendering APIs or establish a relationship to an earlier Flash implementation.

Construct 2 is another supplied authoring-tool label. Exactly one game here carries it.

The distribution is not even across genres

The current label counts differ across categories. They do not show which technology replaced Flash in any genre.

Racing includes 18 WebGL-labelled games out of 30. Racing in City, i8 City Driver and Urus City Driver carry that label. Arcade GP and Moto Race City are listed as Javascript.

Puzzle runs the other way: 27 of 37 are Javascript-labelled. The label does not by itself establish runtime demands.

Sports includes 14 Javascript, 5 WebGL and 8 Construct 3 titles in the current library.

What the catalogue cannot establish

Compatibility and failures. The labels do not establish browser-version compatibility or rule out loading errors, crashes or other failures.

Mobile play. A technology label does not verify phone compatibility. Each game’s documented controls and compatibility still need checking.

Security. Adobe’s end-of-life notice says Flash Player no longer receives updates or security patches. The catalogue labels do not assess the security of a game or its dependencies.

Performance and historical implementations. Air Strike 2D is listed as Construct 3 with a 1280x720 canvas and keyboard controls. Dead Paradise is listed as a WebGL vehicle shooter. These records do not establish their performance or what an earlier Flash implementation could have supported.

Files and preservation. The supplied metadata does not list every file, asset or server dependency. It cannot establish whether a game can be archived or recovered if its host becomes unavailable.

Reading the label yourself

The technology field is on every catalogue game page. It identifies the supplied label; Javascript, Construct and WebGL labels do not establish lightweight performance or broad device compatibility.
