Tool insights
BLA adds protection to build outputs such as JavaScript bundles, Electron apps, WebAssembly and native binaries. It works from the command line, from AI coding tools through MCP, or as a bundler plugin.
AI agents can read, unpack and explain shipped code much faster than a person can. Developers who distribute client-side or packaged software have few tools aimed at slowing down that kind of automated analysis.
Developers and teams that ship JavaScript, Electron, mobile or native software and worry about AI-driven reverse engineering. It is probably not for people who only run server-side code, or who need a hosted service with support and an SLA.
What it does
BLA (package name bla-agents) is an open-source tool for hardening software artifacts against AI-assisted reverse engineering. It runs as an MCP server and as a CLI. It works locally in Node.js, so your build outputs do not need to be sent to a hosted service.
The main use case is simple. You build an app or library, then run BLA on the output before you distribute it. The aim is to make automated analysis by AI agents and static analyzers harder and less useful. The site does not name the maker, so the project is credited only to its GitHub repository.
Key features
- Covers 19 artifact formats, according to the project.
- Supported targets include JavaScript, TypeScript, Electron, WebAssembly and Python.
- It also lists SQLite files, AI model files, native binaries, Android and Unity.
- Resource budget guards limit how much output a static analyzer can produce.
- Decoy control-flow and evidence techniques are used to mislead analysis. The facts do not explain how they work in detail.
- Setup is one command:
npx bla-agents setup. - Bundler plugins exist for Vite, Webpack, Rollup and esbuild.
- It runs locally in Node.js.
