Built for binary analysis

Synalyze It! helps you move from bytes to meaning by combining a fast editor with structured decoding. When you discover a format once, you can capture it as a grammar and reuse it.

Interactive grammars

Define structures and decode files automatically — perfect for reverse engineering unknown formats.

Smart views of selections

Interpret selected bytes as numbers/strings/structures to validate hypotheses quickly.

Search & analysis tools

Incremental search, masks, histograms, and other utilities to find patterns in binary data.

Designed for speed

Navigate and edit large files responsively, so your tooling never gets in the way.
