Its public history is thin, but the official repository and release list show a focused TypeScript CLI and web-demo tool that became packageable through npm-style workflows and Homebrew. ### Project history The official README describes Synchrony as a JavaScript cleaner and deobfuscator, primarily for javascript-obfuscator output. It exposes a hosted web version, an API reference, and a CLI command named `synchrony` for deobfuscating files. The README states that there is no user configuration yet and that the string decoder works automatically, which keeps the command-line surface small. ### Adoption history The GitHub repository shows a TypeScript project with public releases, and the releases page lists v2.4.5 as the latest release in November 2023. The input package metadata lists Homebrew and Nix packaging, while the README documents global npm, yarn, and pnpm installation under the `deobfuscator` package. ### How it is used Typical usage is to install the deobfuscator globally, fetch or provide an obfuscated JavaScript file, and run `synchrony deobfuscate file.js`, producing a cleaned output file. The README asks users reporting transformer errors to provide terminal output and a reproducible obfuscated file or config. ### Why package nerds care Synchrony is package-manager interesting because it packages an AST-heavy reverse-engineering workflow as a simple CLI and web app. It also illustrates a common JavaScript-tooling pattern: the package name, executable name, GitHub repository, generated docs, and hosted demo do not all share one exact label. ### Timeline - 2023: GitHub releases list v2.4.5 as the latest public release. - Current README: Documents hosted use at deobfuscate.relative.im, npm-family global installs, and the `synchrony deobfuscate` command. ### Related projects - The README explicitly targets javascript-obfuscator and obfuscator.io output, and suggests trying older Synchrony versions or another deobfuscator when old obfuscator artifacts do not cleanly deobfuscate. ### Sources - - - - input source_facts.package-manager ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** synchrony - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Nix - synchrony: normalized package name match | nixpkgs package indexes: pkgs/by-name/sy/synchrony/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Related links - [Package publisher tools](https://www.automicvault.com/pkg/package-publishers/) - Belongs to a package publishing or registry command family. - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [node](https://www.automicvault.com/pkg/brew/node/) - Runtime dependency declared by Homebrew. - [fallow](https://www.automicvault.com/pkg/brew/fallow/) - Shares av.db curated category or tags: cli, code-analysis, developer-tools, javascript. - [cargo-llvm-lines](https://www.automicvault.com/pkg/brew/cargo-llvm-lines/) - Shares av.db curated category or tags: cli, code-analysis, developer-tools. - [clang-include-graph](https://www.automicvault.com/pkg/brew/clang-include-graph/) - Shares av.db curated category or tags: cli, code-analysis, developer-tools. - [clang-uml](https://www.automicvault.com/pkg/brew/clang-uml/) - Shares av.db curated category or tags: cli, code-analysis, developer-tools. - [cloc](https://www.automicvault.com/pkg/brew/cloc/) - Shares av.db curated category or tags: cli, code-analysis, developer-tools. - [cppinsights](https://www.automicvault.com/pkg/brew/cppinsights/) - Shares av.db curated category or tags: cli, code-analysis, developer-tools. - [loc](https://www.automicvault.com/pkg/brew/loc/) - Shares av.db curated category or tags: cli, code-analysis, developer-tools. - [ohcount](https://www.automicvault.com/pkg/brew/ohcount/) - Shares av.db curated category or tags: cli, code-analysis, developer-tools. - [undeclared-identifiers](https://www.automicvault.com/pkg/npm/undeclared-identifiers/) - Both packages touch the same language runtime or ecosystem.
