Binary Ninja
Interactive disassembler, decompiler, and debugger with C++, Python, and Rust APIs and a free cloud tier.
Technical Architecture & Overview
Binary Ninja from Vector 35 provides an intermediate-language-based decompiler and disassembler with automation APIs in Python, Rust, and C++. It supports many architectures and includes a debugger. Binary Ninja Cloud runs free in the browser, and a free desktop edition for evaluation and education supports x86, x86_64, ARMv7, and AArch64, though neither free option includes the API or plugin ecosystem. Paid Non-Commercial, Commercial, and Ultimate editions cover full use. Version 6.0 added binary similarity and MCP support, and the Sidekick AI assistant is offered alongside.
Targeted Technical Use Cases
Automation-heavy reverse engineering where scripting quality matters as much as the GUI.
Evaluation & Trade-offs
Core Strengths
