squadreplay

squadreplay is a library-first Rust parser and CLI for Squad UE5 replay data.

The library exposes typed bundle APIs for:

• parsing .replay files into a Bundle
• reading and writing .sqrj.json bundles
• reading and writing .sqrb bundles
• deriving compatibility JSON from a parsed bundle

Library

Add as a dependency (without the CLI):

[dependencies]
squadreplay = { version = "0.1.0-alpha.1", default-features = false }

use squadreplay::{parse_file, ParseOptions};

fn main() -> Result<(), squadreplay::Error> {
    let bundle = parse_file("match.replay", &ParseOptions::default())?;
    println!("players: {}", bundle.players.len());
    Ok(())
}

CLI

Install the binary:

cargo install squadreplay

squadreplay parse match.replay --format sqrj,sqrb --output out/match
squadreplay inspect match.replay
squadreplay show out/match.sqrb
squadreplay unpack out/match.sqrb --output out/unpacked

Feature Flags

Feature	Default	Description

Library-only consumers should disable default features to avoid the clap dependency.
