Boomerang Decompiler vs Buster: Side-by-Side Comparison (2026)

Boomerang Decompiler

Reverse engineers and threat analysts doing malware triage or legacy binary assessment will find Boomerang Decompiler's free, cross-architecture approach valuable when commercial decompilers are overkill; the 400 GitHub stars and active maintenance signal it's genuinely used in the field, not abandoned. The open source model means you can audit the decompiler itself and integrate it into automated analysis pipelines without licensing friction. Skip this if you need GUI-first interaction or support for the latest obfuscation techniques; Boomerang excels at straightforward architectural recovery, not defeating intentional anti-analysis.

Buster

Penetration testers and red teamers running phishing campaigns will extract the most value from Buster because it automates email reconnaissance at scale without touching any infrastructure. The tool's free pricing and 1,280 GitHub stars signal active adoption among practitioners who need to validate targets and enumerate valid email formats before engagement. Skip this if your team needs post-compromise email forensics or mailbox analysis; Buster is purely offensive reconnaissance, not incident response.
