Detects internet reachability and streams status changes via reactive flows; singleton entry, validated connectivity (avoids captive-portal false positives), synchronous shortcuts and test fakes.

Customizable file picker with searchable grid and menu views, smooth UI previews, multi-selection, localization support, extensible theming and easy integration into app interfaces.

Implements Material Design tap targets for feature discovery, offering a coordinator, modifier-based attachment, customizable styles and text definitions, chained targets support, and an example app.

Pure systems-programming toolkit enabling bit-exact C semantics with single-heap memory, C-compatible types, deterministic floating-point, and dual-mode bitshift engine for reliable C-to-language porting.

Framework-agnostic on-device LLM inference with a unified OnDeviceGenerator API: single-shot and streaming generation, model download/progress tracking, systemInstruction handling, and simple cancellation semantics.

Fake-data generator for tests that builds realistic object graphs with scoped overrides, deterministic seeds, nested targeting, collection/map handling, null/default control, and extensible add-ons.

Reusable patterned backgrounds and follow-glow visuals for Compose, with immutable styles, runtime states, rich layout and interaction presets, lightweight blur, parallax, and seeded randomness.

API wrapper for traQ bots offering coroutine-friendly DSL-style event handlers (onMessageCreated), message-reply utilities, token-based initialization, and a simple run lifecycle for quick bot setup.

Truly native date picker UI leveraging system pickers, auto-inheriting app theming; asynchronous suspend-style APIs for single or range selection, plus UI toolkit helper.

Lightweight, customizable Material 3 date picker offering single and range selection, range highlighting, easy theming, and state API exposing selected date, range, and current month.

Transparent proxy converting non-stream OpenAI Responses and Chat Completions requests into SSE upstream streams, aggregating events in memory and returning single JSON responses, while passing through streaming requests unchanged.

Ultra-lightweight LaTeX math renderer: lexer/parser and AST, independent layout engine and native renderers, automatic line breaking, modular parser, optional bundled STIX Two Math font.

Interactive Jupyter notebook integration enabling deep-learning experimentation with type-safe tensors, inline image/Graphviz rendering, autograd graph visualization, SIMD-accelerated and quantized kernels.

Type-safe, reflection-free diffing of serializable data structures, performing deep comparisons of nested objects, lists, and maps; supports compile-time serializers, customizable list strategies and formatted statements.

SSE network transport enabling GraphQL subscriptions over graphql-sse, with configurable headers, reconnection policy, and pluggable HTTP client optimized for streaming.
