rev.ng
Milan, Italy
What it is
rev.ng is a decompiler for reverse engineering that produces syntactically valid, standard-compliant C from supported binaries. It can detect structures such as linked lists, structs, and arrays using information across functions. Listed default architectures include 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 through YAML files. A client-server design supports interaction through an HTTP API, and debugger integration and a scripting API are listed. The interface is described as available in a browser or standalone app, with cloud and standalone use offering the same experience; the site invites users to join a closed beta for the UI. Collaborators can work on a project through a shared URL, with public projects allowing two collaborators. The company says the decompilation pipeline is Free Software, while the UI is intended for commercial cloud and standalone versions. rev.ng is free and lists API, Linux, macOS, web, and Windows platforms.
For and against
For
- Produces standard-compliant C code
- Detects data structures using interprocedural information
- Supports a client-server HTTP API
- Offers browser and standalone interfaces
Against
- UI availability is listed as a closed beta
- Public projects allow two collaborators per project
- UI versions are intended for commercial offering
The verdict
rev.ng combines binary decompilation with structure recovery, API interaction, and project collaboration. The site invites users to join a closed beta for the UI, and distinguishes the Free Software pipeline from the intended commercial UI versions.
Who it suits
rev.ng suits reverse-engineering users working with its listed binary formats and architectures. Its HTTP API, YAML workflow, and shared projects may also fit automated or collaborative work.
