Headless authentication SDK supporting consumer and B2B flows: OTPs, magic links, passwords, OAuth, passkeys, biometrics, TOTP, crypto wallets; session/user and organization management, RBAC, SCIM, recovery flows.

High-performance arbitrary-precision BigInteger and BigDecimal implementations with zero-overhead standard aliases, pure native hot paths plus LibTomMath fallback, and extensive microbenchmarks demonstrating major speedups.

Type-safe, annotation-driven DataStore code generation producing zero-boilerplate compile-time implementations from simple interfaces; supports suspend and reactive reads, typed preferences, object serialization, and constructor/reflection instantiation.

Collection of libraries offering lexicographically-sortable ULIDs, zero-overhead 64-bit BitSet with bitwise ops and set-bit iteration, and unified asynchronous file I/O including OPFS support.

Encodes and decodes binary data to compact, human-friendly Base58 strings (plain, no checksum); includes fixed-width typed helpers (ints, UUIDs), preserves leading zeros, rejects invalid input.

Monitors network connectivity state and emits real-time callbacks via a lightweight API, enabling straightforward registration of listeners and simple integration into shared application code.

Material-style toast notifications with single root host, multiple styles (gradient, glass, animated), built-in success/error/warning/info types, custom icons, Lottie and action/duration controls.

compose multiplatform html render

Decomposes Compose presenters, eliminating callback and event plumbing by generating compile-time routing between parent and child events/effects, enabling clean, callback-free fused sub-presenters.

Ready-to-use animated loading/spinner indicators with extensive customization, a linked catalog for lookup/random selection, and a showcase grid featuring 30+ styles.

Compile-time, type-safe object mapping via annotations; generated mappers return Result<T> with path-aware errors, compile-time lossless-conversion checks, fallback ladder, pluggable converters and observability.

Reimplements a Chinese music-service API with strict encryption parity (MD5, AES‑CBC, RSA‑PKCS1), modular design covering 17 categories and 112 endpoints for auth, search, songs, and playlists.

Modern image cropper with stretchable/resizable selection, image pan and zoom, locked bounds, 90° rotation, aspect-ratio presets (Free, 1:1, 4:3, 16:9), and automatic downscaling under 1 MB.

Unified, coroutine-friendly wrapper for native in-app review APIs, enabling a single requestReview() call to trigger platform review dialogs with a simple, exception-based completion contract.

Batteries-included WebView toolkit with drop-in UI scaffolding, two-way JS bridge, file/camera/getUserMedia support, progress indicators and error page, debug log panel, optional QR scanner.

UI-agnostic form validation toolkit standardizing immutable, testable input states; supports custom and dynamic validations, aggregated form validity, and submission lifecycle handling.

Small, idiomatic API for copying text to the clipboard with minimal dependencies, coroutine-friendly async operations, simple integration, and test-covered core logic.

Logs outgoing HTTP client requests as reproducible cURL commands, capturing method, URL, headers and body; supports request filtering, sensitive-header sanitization, and custom logger integration.

Pure zero-runtime-dependency Zstandard codec producing standard zstd frames with dictionary support; immutable digested dictionaries reusable across threads, one-shot API, and decompression-bomb guard.

Multiplatform tag logger

Library for mobile shared architectures

Logging wrapper streamlines logger replacement, centralizing logging calls to simplify transitions between logging tools without altering individual class code. Ideal for rare use cases.

Simple complex math library defines a `Complex` class and functions mirroring double operations for complex numbers, with options for importing and creating extension functions.

Enhances WebSocket functionality by adding support for the STOMP protocol, enabling seamless topic subscription and event handling for both Android and iOS applications.
