TypeScript, compiled.
An LLVM-based ahead-of-time compiler that turns TypeScript into standalone native executables. No Node.js required.
ts-aot app.ts -o app && ./appWhat you get
Native Binaries
Single executable output. No runtime dependencies. Compile .ts, .tsx, .js, .jsx to standalone binaries.
Node.js Compatible
32 built-in modules: fs, http, net, crypto, streams, and more. 11 npm packages verified (semver, uuid, nanoid, etc.).
LLVM Optimized
Full O0-O3 pipeline with type-driven codegen, NaN-boxing, escape analysis, and flat inline-slot objects.
Real TypeScript
Classes, generics, async/await, decorators, generators, iterators, destructuring, and more. Not a subset.
Performance
AOT compilation eliminates JIT warmup. ts-aot shines in cold-start and recursive compute workloads.
Cold Start
2x faster startup -- no JIT warmup needed
Recursive fib(35)
1.7x faster -- AOT excels at recursive calls
V8's JIT excels at long-running array and string operations. See limitations for a full comparison.
How it works
A hand-written C++ parser feeds into type-aware analysis, SSA-based HIR with 8 optimization passes, then LLVM 18 for native code generation. The result links against a custom C++ runtime with mark-sweep GC, ICU strings, and libuv async I/O.

Built by Claude
ts-aot is written entirely by Claude, Anthropic's AI assistant. The compiler, runtime, extension system, test suites, and this website were all generated through conversation with a human collaborator.
That means ~100,000 lines of C++20, a hand-written recursive descent parser, a custom mark-sweep garbage collector with generational nursery, 8 SSA optimization passes, 32 Node.js API modules, and 560+ passing tests -- all produced by an AI pair-programming with Claude Code.
The project is an experiment in what AI-assisted software engineering can produce today. Every line of code was written by Claude, with human direction on architecture and priorities.
