Afterburner is a Rust-based JavaScript/TypeScript runtime that provides capability-sandboxed execution with memory limits, timeouts, and gated I/O. It offers its own package format, registry, and package manager, and includes unique features like AI agent integration for secure code execution. The project is interesting for combining a custom sandboxing model with a full package ecosystem and embedding support.
