Roadmap

Our vision for MetaScript's future. This roadmap is updated quarterly.

Current Focus (Q1 2025)

Compiler Stability

• Fix remaining edge cases in type inference
• Improve error messages with suggestions
• Performance optimization for large codebases

JavaScript Backend

• Complete ES2020+ feature support
• Better tree-shaking for smaller bundles
• Source map accuracy improvements

Documentation

• Complete API reference
• More real-world examples
• Video tutorials

Coming Soon (Q2 2025)

Language Features

• Pattern Matching: Full match expressions with guards
• Async Iterators: for await support across all backends
• Module System: Improved circular dependency handling

C Backend

• Windows cross-compilation support
• WebAssembly target (experimental)
• Smaller binary sizes

Erlang Backend

• Hot code reload improvements
• Better OTP integration
• Distribution helpers

Future Plans (2025+)

Language Evolution

• Effect System: Track side effects in types
• Linear Types: Optional ownership tracking
• Dependent Types: Types that depend on values (research)

New Backends

• LLVM: Direct LLVM IR generation
• WASM: First-class WebAssembly support
• JVM: Java/Kotlin interop

Ecosystem

• Package Registry: Dedicated package hosting
• Build System: Integrated build orchestration
• More IDE Plugins: Emacs, Sublime Text, Helix

Open Source

MetaScript is MIT licensed — fully free and open source software.

Timeline

Why closed preview until July?

The compiler just completed its self-hosting bootstrap — the Zig scaffolding has been retired, and MetaScript now compiles itself. We're using the window before public source release to:

1. Stabilize the standard library — freezing public API surface before opening to community contributions
2. Finalize editor tooling — language server, tree-sitter grammars, and VS Code/Neovim/Zed plugins ready for broad use
3. Ship the documentation generator — so internal types and public docs stay in sync the moment source goes public

The binary, playground, and package registry are live today. Compiler source opens July 1, 2026 — we commit to this date and will not slip it. The MIT license commitment is firm.

How We Prioritize

Our priorities are driven by:

1. User feedback: What the community needs most
2. Stability: Fixing bugs before adding features
3. Performance: Making MetaScript faster
4. Ergonomics: Improving developer experience
