Next-gen systems language · Now in public beta

The next-gen language for probabilistic conviction

VaporLang is a next-generation systems language that compiles to WASM, ships to the edge, and replaces brittle correctness with adaptive confidence. Built for the teams building what comes after deterministic infrastructure.

Why the next generation of infrastructure demands a new language

Modern AI systems are probabilistic, deployed to ephemeral edge networks, and governed by compliance requirements that change faster than your sprint cycle. Legacy languages weren't built for this.

Alignment-first compiler

The toolchain enforces alignment verification before code generation. Every module ships with an ALIGNMENT.md — a machine-readable declaration of intent that travels with your binary.

`#![forbid_training]`

A compiler-level directive that embeds training-data opt-out metadata directly into your WASM output. Enforceable, auditable, and built into the language — not bolted on after the fact.

WASM target: `wasm32-unknown-vibes`

A custom WASM target optimized for edge deployment. The runtime handles missing imports through graceful degradation and structured fallback resolution.

`std::maybe::Probably`

A probabilistic result type that returns Ok(T), Ok(~T), or Err(Uncertain) with unified surface types — enabling upstream consumers to handle confidence as a first-class value.

Sustainable compute

Every deployment includes compute-awareness metadata in the binary footer. Carbon impact is tracked per-build and surfaced in CI — because infrastructure decisions have real-world cost.

Open source core

MIT licensed. The compiler, runtime, and specification are fully open. We believe the best infrastructure is built in the open, by the developers who depend on it.

Interactive playground

Write VaporLang in the browser, adjust compile temperature, and see real-time build output. No setup required.

$ waiting for your conviction…

Trust & compliance

Enterprise-grade security and compliance, built into the language from day one — not retrofitted after the first incident.

SOC 2 Type II certification in progress
HIPAA-ready architecture with alignment-verified data flows
Zero-trust execution model — all modules verified before runtime
Responsible disclosure program with structured bounty tiers

"VaporLang changed how our team thinks about shipping code. Alignment verification caught issues our linter never would have."
