capabilities
01
Sub-50ms speed
Rust-native engine processes thousands of lines in milliseconds. No cold starts, no queue.
02
SSA reconstruction
Static single-assignment analysis recovers variable scopes, loops, and control flow accurately.
03
Semantic renaming
Recovers names from require(), GetService(), WaitForChild() call patterns.
04
Encode key support
Handles Roblox bytecode encoding with configurable key (default 203) for accurate parsing.
05
Rich annotations
Optional line, function, and upvalue comments to aid understanding of decompiled output.
06
REST API
Simple HTTP endpoint — integrate into any tool, exploit, or script pipeline.
about cherry

PURE RUST.
BUILT FOR
PRECISION.

Cherry is a high-performance Luau decompiler written entirely in Rust. It reconstructs readable Lua source from raw or base64-encoded bytecode produced by the Roblox engine.

The core pipeline uses control-flow graph analysis, SSA form, and structured loop detection — producing output that mirrors original source, not a raw disassembly dump.
