IDA Pro - A Powerful Disassembler, Decompiler & Debugger

The disassembler, decompiler and debugger

Disassembler

Break any binary into annotated assembly across 70+ processor families, with cross-references, graphs and naming that persist as you work.

Read the docs

Decompiler

Read machine code as clean C-like pseudocode. Rename and retype interactively, and the output updates as you reason.

Read the docs

Debugger

Step through the same database you analysed statically, local or remote, on desktop, embedded and mobile targets.

IDA is more than a GUI

IDA is not only a GUI. It’s a library, a CLI, and a tool your AI agent can drive.

01 For agents

IDA MCP

Connect IDA to Claude, Cursor or any MCP client. The model reads your database (pseudocode, xrefs, strings, call graphs) and can rename and annotate as it reasons.

docs · ida-mcp

02 API

Domain API

Scripting in the language of reverse engineering, not the SDK. Functions, types and xrefs are first-class objects. Open source, pip install ida-domain.

ida-domain.docs

03 Library

idalib

The whole IDA analysis engine as a library, no GUI. Batch-triage a thousand samples, build a scanner, or embed IDA in your own product.

docs.idalib

04 CLI

hcli

The Hex-Rays command line: install IDA, manage licenses and plugins, and script your whole setup from one tool.

docs · hcli

05 Add-on

Assist add-on

IDA’s built-in AI harness. Ask questions, rename and comment, and get explanations without leaving the database.

docs · assist

06 License

IDA Pro Headless

The same IDA engine, no GUI. License it for servers and CI, batch-triage at scale, and drive analysis from your own automation.

FLIRT 2.0 signatures and 28M-function Lumina
...

01 New in 9.5

Apple Kernel Cache & DriverKit

Deeper analysis of Apple’s low-level OS: expanded kernel cache support and DriverKit binaries that used to demand heavy manual work.

docs · apple

02 New in 9.5

SSE, AVX & Armv9

Correct disassembly and decompilation of modern x86 SIMD (SSE and AVX) and the newest Armv9 CPUs in mobile, embedded and server chips.

docs · isa

03 New in 9.5

TriCore decompiler

A first-generation decompiler for Infineon TriCore turns automotive and industrial firmware into readable high-level code, not just assembly.

docs · tricore

04 New in 9.5

Android DEX decompiler

Analyse native Android apps inside IDA: DEX bytecode becomes readable Java for application research and malware triage.

docs · dex

05 New in 9.5

FLIRT 2.0 signatures

Next-generation signature bundles auto-identify more statically-linked library code, so your time goes to the code that matters.

docs · flirt

06 New in 9.5

Demangler & parser overhaul

More accurate, readable symbol names for modern C++, plus reliable parsing of the latest compiler output and metadata.

docs · demangler

Rust, Swift, C++ & Go

Cleaner pseudocode and better recovery of high-level constructs across Rust, Swift, Go and modern C++ binaries.

docs · languages

Pathfinder

Discover call paths between any two functions, with multiple waypoints and cross-reference-aware navigation.

docs · pathfinder

Xrefs Graph

the path spine and waypoints are highlighted with dedicated colors, and a path-aware aligned layout keeps the route readable.

docs · Xrefs Graph

I currently have IDA Pro 8.x, what are my options to get to IDA 9.0?

You have two options:

If your perpetual license is in active support, you do not need to purchase a subscription to access IDA 9 under the new subscription model. Your active license allows you to receive a free subscription to IDA 9! To start using IDA 9 today you can access the installer in the new customer portal at my.hex-rays.com. There you can request a license key for your free subscription. Please note that the license key for your free IDA 9 subscription will expire at the end of your active support period. You can find detailed instructions on how to upgrade to IDA 9 here.

If your perpetual license has run out of support, or your support period is about to end, you can select a plan here and upgrade within our customer portal, my.hex-rays.com. For any questions or doubt, do not hesitate to contact sales@hex-rays.com

Can I get IDA Pro with a monthly subscription?

We offer solely yearly subscriptions.

Can I purchase IDA with a perpetual license?

Perpetual licenses are no longer offered as from September 30, 2024 as Hex-Rays adopts a subscription-based licensing model.

Any perpetual licenses bought before September 30, 2024 will remain valid and continue working according to their licensing terms. This means that you can continue to use indefinitely the specific IDA Pro version that you purchased before that date.

Please bear in mind that updates and support for previous versions will be discontinued after one year of the activation date.
