rev.ng
What it is
rev.ng is a decompiler for reverse engineering that turns supported binaries into syntactically valid, standard-compliant C. Its data-structure recovery uses information across functions to identify linked lists, structs, arrays, and arrays of structs. The listed default architectures are x86, x86-64, ARM, AArch64, MIPS, and S390X; supported imports include ELF, PE/COFF, Mach-O, DWARF, PDB, and IDB. Users can define functions, edit prototypes, and rename items in YAML files, or interact through an HTTP API. The interface is described as available in a browser or standalone app, with cloud and standalone use offering the same experience. Collaborators can share a project URL; public projects include two collaborators. The rev.ng decompilation pipeline is Free Software, while the UI is intended for commercial cloud and standalone versions. The service is free and lists API, Linux, macOS, web, and Windows platforms. The site invites users to join a closed beta for the UI.

rev.ng in depth
Read the full write-up
rev.ng is a reverse-engineering decompiler that turns binaries into C and helps recover the data structures behind them. It best suits analysts and developers who need multi-architecture analysis, repeatable workflows, or shared projects. Its Free Software pipeline is a strong foundation, but the UI is still in closed beta and commercial plans do not yet have published prices.
Overview
rev.ng combines decompilation with structure recovery and ways to automate or organize analysis. It emits syntactically valid, standard-compliant C and uses information across functions to detect structures such as linked lists, structs, arrays, and arrays of structs. That can provide a more useful starting point for understanding a binary than code output alone, though recovered structures still require interpretation.
The licensing is mixed: the decompilation pipeline is Free Software, while the UI is planned as a commercial cloud or standalone product. Both UI forms are described as offering the same experience, and the standalone option is fully offline. The browser and standalone UI are in closed beta, so teams that need a generally available graphical workflow should be cautious about building their process around it.
Key features
Architecture and file-format coverage: The default architecture set includes x86, x86-64, ARM, AArch64, MIPS, and S390X. Imports include ELF, PE/COFF, Mach-O, DWARF, PDB, and IDB, a broad mix for work across common executable formats and debugging data.
Automation: A client-server design exposes an HTTP API, and YAML files can define functions, edit prototypes, and rename items. This favors repeatable analysis and integration into scripts or established workflows over purely manual use.
Collaboration: Projects can be shared by URL. Public projects allow two collaborators per project; private plans offer unlimited collaborators, which better fits team work but are priced custom.
Analysis tools: Native-code decompilation, debugger integration, and a scripting API support a broader reverse-engineering workflow than decompilation alone.
Pricing
The pricing model is free, and the open-source plan covers the core pipeline. The Open source plan has no listed price and includes runs-anywhere use, private projects, and all architectures, making it the clearest fit for users who want the pipeline without a commercial UI plan.
The Public project plan has no listed price and allows two collaborators per project. It is suited to small shared efforts where public visibility is acceptable. The Private project plan has custom pricing and is billed TBD; it adds cloud use, all architectures, unlimited collaborators, and private visibility. The Standalone plan is also custom pricing and billed TBD, with fully offline use, all architectures, unlimited collaborators, and private visibility. That option is the better match when offline operation is essential; neither commercial plan has a published cost to compare.
Platforms
rev.ng identifies API, Linux, macOS, web, and Windows as platforms. The UI is described as available through a browser or standalone app, while the open-source pipeline runs anywhere. The standalone commercial option is fully offline.
Who it's for
rev.ng is a good fit for reverse engineers who value an open decompilation pipeline, need to cover several architectures, or want to automate analysis through an API and YAML-defined changes. It also makes sense for teams that can work with URL-shared projects and choose visibility to suit their needs. It is less suitable for users who require a mature, broadly available UI immediately or need firm commercial pricing before choosing a tool.
Pros and cons
Pro: Structure detection alongside standard-compliant C can give analysts both code and useful clues about how data is organized.
Pro: The HTTP API, scripting API, and YAML workflow controls support automation and repeatability.
Pro: The open-source plan includes private projects and all architectures, while the standalone plan provides an offline path.
Con: The UI is in closed beta, limiting its suitability for teams that need dependable general access now.
Con: Commercial plans are billed TBD with custom pricing, making cost planning harder.
Con: Public projects are limited to two collaborators, so larger teams need a private plan.
Alternatives
JEB is worth considering for researchers, students, hobbyists, and nonprofit reverse engineers who want a free Community Edition with x86 and x86-64 decompilation; it also offers a free trial.
Binary Ninja may suit evaluation or education use with its free tier, while its Personal plan is a perpetual license for users who want a paid option. Its free version is limited to five decompilation architectures and excludes API and plugin access, unlike rev.ng's stated API and scripting support.
Boomerang is a free, BSD-licensed open-source decompiler for readers who prioritize that licensing and want a Linux, macOS, or Windows option.
IDA Pro offers a free tier for x86-32 and x86-64 disassembly with two cloud-based decompilers, and a paid Essential plan at 1099.00 USD for those who prefer its stated plan structure.
RetDec is a free, MIT-licensed open-source alternative for users seeking software available on Linux, macOS, self-hosted systems, or Windows.
uncompyle6 is a free GPL-3.0 Python bytecode decompiler, a more specific fit for readers working with Python bytecode.
Bytecode Viewer is a free, GPL v3 copyleft open-source option for users who want a tool in that licensing category.
Decompiler Software and Reverse Engineering Tools are useful starting points for comparing the broader categories.
Verdict
Choose rev.ng if you want a Free Software decompilation pipeline that combines C output, structure recovery, broad architecture support, and automation hooks. Its strongest case is for technically capable users building repeatable reverse-engineering workflows. Look elsewhere if your work depends on a generally available graphical interface or a published commercial price today.
Verdict
rev.ng pairs binary decompilation with structure recovery and automation options. The pipeline is Free Software, while commercial cloud and standalone UI versions are planned.
