Update, September 2026. AfterPack is live and the waitlist is closed. Current plans and prices are on /docs/tiers and what has shipped is on the roadmap. I have kept this post as it was written, except for a few claims that ran ahead of what we ship.
Today, I'm excited to announce the public waitlist for AfterPack — a next-generation JavaScript obfuscator built from the ground up to protect your code in the AI era.
The Problem
JavaScript obfuscation has been around for decades, but the landscape has fundamentally changed. Modern AI models like Claude can explain minified code in seconds. Security scanners map your attack surface automatically. And reverse engineering tools have never been more powerful.
Traditional obfuscators weren't built for this world. They rely on techniques that AI can see right through:
- Simple string encoding that LLMs decode instantly
- Predictable control flow patterns that tools unravel
- Symbolic naming that hints at functionality
Your source code is shipping with every deployment. Attackers, competitors, and AI crawlers are reading it.
The Solution
AfterPack takes a fundamentally different approach. Instead of just making code hard to read, we make reversing it expensive: every build comes out structurally different, so nothing an attacker or an AI learns from one build carries over to the next.
What Makes AfterPack Different
Built with Rust. AfterPack's core is written in Rust for maximum performance. Transform your entire codebase in milliseconds, not minutes.
Built for the AI era. Polymorphic transformations mean there is no fixed structure for a model to learn: the same source produces a different program on every build.
Framework-Aware. Auto-detection for Next.js, Vite, Astro, Remix, and more. Zero configuration required — just run npx afterpack after your build, or use AfterPack's native plugins/extensions for popular frameworks.
Production-Ready. No eval(), CSP compliant, source maps included. Works at the edge on Cloudflare Workers.
Free Forever
The CLI and the framework plugins are free and open source, and the Free tier has no build limit:
- Unlimited builds
- All basic transforms (renaming, control flow, string encoding)
- Source maps for debugging
- Framework presets
- Deterministic builds for CI caching
Pro When You Need It
For teams that need more protection, AfterPack Pro adds advanced features:
- Protection you can aim — per-file and per-region overrides, so the heaviest preset lands only on the code that matters
- Cloud builds with history — the same engine running in Cloudflare Workers, with a stored Protection Map for every build
Plans start at $49/month for indie developers and scale to enterprise with dedicated support and isolated runtimes.
Get started
AfterPack is live. Run npx afterpack after your build, or follow the quickstart for your framework.
Ship software. Not source.
The JavaScript ecosystem deserves better protection. AfterPack is building it.
