OpenAI-compatible SDK offering chat completions (streaming and non-streaming), text embeddings, model browsing across 40+ models, SSE streaming, thread-safe singleton, and API-key redaction.

Collection offering analytics, authentication, billing, offline-first sync, adaptive UI, i18n and OCR abstractions; dependency-free interfaces with NoOp fallbacks and platform-specific SDK integration points.

Unified Firebase Remote Config access through a single API, fetchAndActivate, typed getters, JSON export, simple initialize, optional auto-refresh and REST-backed local cache.

Immutable, append-only, cryptographically linked chain for tamper-evident local data sync with content deduplication, HTTP/TCP sync modules, reactive updates, pluggable persistence and conflict merging.

Paint-aware color mixing using a subtractive physical model plus a learned residual correction for realistic results; includes runtime, interactive demo, model artifact and training tooling.

Unified Compose API delivering platform-native UI components with customizable Material and UIKit-backed elements, lightweight interop, extensive styling options, and multiple button variants.

High-performance, zero-reflection JSON serializer generating optimized zero-copy byte serializers via compile-time code generation; thread-safe registry, null-safety and memory/DoS safeguards, prewarm.

Full CSS Flexbox layout model for Compose UIs with stable, versioned API, advanced features (wrap-reverse, baseline, percent basis), per-item positioning, overflow controls, and headless engine.

Comprehensive Rust toolkit for building Liquid Network wallets and apps, offering modular components that abstract protocol complexity, wallet primitives, and integration-friendly APIs.
