flashkit-studio

Desktop SWF inspector for Adobe Flash files and AVM2 bytecode. Browse classes, recover AS3 source, trace references, and explore the constant pool.

Built on flashkit using PySide6 (Qt 6).

Features

• Class browser — sidebar tree grouped by package, with class glyphs and a fuzzy filter that matches member names too.
• AS3 source view — full decompiled output with syntax highlighting, line numbers, and find-in-file.
• P-Code view — AVM2 disassembly with resolved operands.
• Strings, Multinames, Traits views with filter inputs.
• Symbol palette — Ctrl+P fuzzy search for classes, methods, fields across the whole SWF.
• Find in files — Ctrl+Shift+F greps decompiled source across all classes, results grouped by class.
• Jump to definition — Ctrl+click or F12 on an identifier; works on obfuscated names too.
• Outline pane — fields and methods of the active class, click to scroll to definition.
• Bottom panel with tabs for References, Class hierarchy, Bookmarks (Ctrl+B), and Assets (extract embedded bitmaps / sounds / fonts).
• Recent SWFs menu, drag-and-drop to open, persistent window state and sidebar side.
