Why HexForge

Designed around real analysis needs

Traditional hex editors require licenses, installs, and setup. HexForge takes a different approach.

credit_card_off Typical Desktop Tool

Commercial hex editors often require annual licenses that can cost hundreds per seat.

Script console & plugins

Write JavaScript scripts with the hf API, or install WASM plugins from the marketplace to add new parsers and tools.

Use Cases

How people use HexForge

Built for security researchers, CTF players, reverse engineers, and developers.

01

Quick file inspection

Need to inspect a file's headers, check entropy, or extract strings? Drop the file into HexForge and get results instantly — no setup needed.

✓ Auto file format detection ✓ String extraction ✓ Entropy visualization

02

Visual structure mapping

Complex binary formats are hard to reason about in raw hex. Use the built-in node graph to visually map file structures and trace data flows.

✓ Drag-and-drop node editor ✓ 18 built-in node types ✓ JSON export & import

Scriptable analysis workflows

The built-in script console lets you automate analysis with a JavaScript API. Read bytes, highlight regions, calculate hashes, search patterns, and build custom file parsers.

✓ JavaScript hf API ✓ Built-in snippets ✓ JS template engine
Script Console
// Read first 16 bytes and calculate hash
const data = await hf.read(0, 16);
const hash = await hf.sha256(new Uint8Array(data));
hf.highlight(0, 16, '#44ff44', 'Header');
hf.log(`SHA-256: ${hash}`);
▶ SHA-256: a1b2c3d4e5f6...
