1. The CLI and plugins
The AfterPack CLI and its framework plugins are open source under the Apache License 2.0. Read the source, open an issue, or send a pull request on GitHub.
2. The engine
The engine (@afterpack/core, @afterpack/wasm and their platform binaries) is free to use under the AfterPack Engine License.
You can
- Use it for any purpose, including commercial work and CI, with no usage limits
- Install it as a dependency and keep it in lockfiles, caches, and container images
- Keep the code it produces: it is entirely yours, with no notice, attribution, or royalty
- Build and distribute plugins and tools that call its documented API, under any license
You can't
- Redistribute the engine binary on its own, or inside a competing obfuscation product
- Offer JavaScript obfuscation or code protection to others as a hosted service built on it. Using it inside your own product, where protecting code isn't what you sell, is fine
- Modify it, translate it, or reverse engineer it
- Use it for anything unlawful, or to create, facilitate, or distribute malware, spyware, or phishing
- Remove its notices
3. Pro features
With a Pro key, the same package sends your build to AfterPack's cloud service. That service is covered by the Terms of Service.
4. The license file controls
This page is a plain-language summary. Each engine package ships its full license text in a LICENSE file, and that file is what controls.
