One Foundation. Every Platform. Zero Fragmentation.
A unified TypeScript foundation engineered to power web applications, native mobile experiences, and the tooling behind them with one coherent language of data, state, interaction, and control.
Stop rebuilding shared logic. Start shipping extraordinary experiences.
One engineering philosophy. Every surface. Complete consistency.
The JavaScript ecosystem offers exceptional libraries, but connecting them can create fragmented contracts, duplicated logic, inconsistent behavior, and unnecessary dependencies.
Bun Engine brings the strongest capabilities together behind one deliberate developer experience—shared where it matters, specialized where platforms differ.
The mission is ambitious: write the logic once, preserve the strengths of every runtime, and make sophisticated application engineering feel effortless.
The latest release — checksummed, attested, one command per platform.

A continuously evolving foundation for modern TypeScript engineering.
Types, Errors & Results · Typed APIs & Contracts · HTTP & Realtime · Validation & Parsing · State, Cache & Storage · Authentication & Sessions · Forms, Navigation & Device · Localization & World Data · Emoji, Flags & Fonts · Design Tokens, Motion & Tooling
From a single validated input to a complete cross-platform experience, every capability speaks the same engineering language.
One vocabulary. Endless possibilities.

Common logic lives in the foundation. Browser and native capabilities stay behind explicit adapters. Frameworks, rendering, branding, and application configuration belong to their consumers.
Bun powers the development workflow; production code runs on the runtime of its actual platform.
No circular dependencies. No duplicated foundations. No platform APIs leaking into shared code.
Not another pile of packages. One coherent TypeScript system.
Every capability follows consistent naming, predictable failures, strongly typed contracts, explicit ownership, and focused public interfaces.
Mature libraries are selected for what they do best, then integrated without hiding important features or creating unnecessary wrappers. Shared dependencies have one owner; platform-specific dependencies stay with the platform that needs them.
Abstractions must remove complexity, not relocate it. Every public capability must serve a real use case and remain easy to understand, compose, and test.
Maximum capability. Minimum friction. Absolute architectural discipline.
Every byte matters. Every render counts. Every request earns its cost.

Optimization targets the full experience: bundle size, startup time, render cost, memory usage, network traffic, and responsiveness.
Improvements are accepted through reproducible measurements and real application workloads—not fashionable techniques or synthetic claims.
Less JavaScript. Less overhead. More experience.
Trust nothing at the boundary. Expose nothing by accident.
Typed contracts, input validation, bounded network operations, secure defaults, and explicit failure handling shape the foundation from the start.
Credentials and business secrets stay outside the shared core. Session-scoped storage, safe transport policies, output handling, and server-rendering boundaries protect applications from accidental exposure and cross-context leakage.
Dependency auditing, targeted tests, and disciplined review reinforce every sensitive capability.
Security is built into the contract—not patched onto the interface.
Build with clarity. Verify with evidence. Evolve without fragmentation.
Bun drives dependency management, scripts, and tests, while strict TypeScript checking, linting, security auditing, contract tests, and benchmarks protect the foundation as it grows.

Engineering excellence isn't a milestone. It's the standard.
