Generates QR-code 2D Boolean matrices via a tiny, dependency-free API; omits rendering so custom renderers or CLI tools can handle visual output and integration.

Ktor client plugin streamlines Storyblok API calls; includes example code and full reference docs to integrate headless CMS content and visual-editor workflows into apps.

Async suspend-based streaming I/O layer exposing AsyncFileSystem/AsyncReadOnlyFileSystem, AsyncCloseable, async raw sources/sinks, buffered AsyncSource, AwaitPredicate, virtual/noop/system filesystems, random/discarding streams, portable implementations.

Payment UI toolkit enabling secure card tokenization via the Conekta API, with built-in tokenizer, crypto and HTTP client, pluggable UI components and CDN-loaded card-brand icons.

Rust-backed, high-performance WebTransport wrapper offering an idiomatic async API for establishing connections, managing uni/bi-directional streams and unreliable datagrams, plus TLS certificate handling.

Generates type-safe, build-time resource access for cross-platform projects, producing platform-specific resource objects and helpers, with override strategies, configurable package and resource-folder naming.

In-app developer toolbox offering network inspection, log viewing, crash reporting, leak detection, device diagnostics and performance monitoring with zero configuration, in-memory storage, dark themes, cURL/PDF export.

Enables real-time bidirectional communication with Phoenix Channels via WebSocket, channel join/leave, push messages, event routing, automatic exponential-backoff reconnection, heartbeat, and type-safe message handling.

Compile-time dependency injection compositor offering annotation-driven DI, graph validation at compile time, generated entry points, singleton support, and fast incremental builds for safe, efficient dependency wiring.

Type-safe test fixture generation with a composable, declarative API for building complex object graphs, nested overrides, sealed/enum/null handling, annotation-driven auto-registration, and testing-framework integration.

SQL-first data access layer for PostgreSQL, with fluent query builders, automatic composite/enum/array type mapping, polymorphic dynamic DTOs, transaction plans, stored-procedure support, and LISTEN/NOTIFY.

CommonMark-compliant Markdown parser and renderer offering AST access for inspection and manipulation, extensible with GFM-style extensions (tables, strikethrough, autolink), outputs HTML, Markdown, or plain text.

Restores lifecycle-agnostic navigation and hierarchical scope management for Compose UIs: visibility-aware lifecycles, type-safe navigation, DI-agnostic dependency scoping, and ref-counted coroutine scopes.

Generates unique, deterministic offline avatars via canvas; multiple stylistic variants (BEAM, MARBLE, PIXEL_ART, EMOJI, WACKY), with customizable colors, size and shape.

Operation-level Mastodon API clients with generated per-operation modules, SDK for composing operations, Gradle tasks, CLI tools, and MCP server exposing Mastodon tooling to AI assistants.

CSS lexer and parser producing a fully navigable AST with exact character offsets per token/node, W3C Syntax Level 3-compliant, plus interactive AST explorer demo.

Creates G2-continuous rounded rectangles and capsules with configurable continuity (G1/G2), tunable arc/Bezier profiles, G1-guarantee and optimized Bézier control-point calculation for efficient rendering.

Enable @Parcelize and Parcelable usage in shared common code; build plugin auto-applies parcelize compiler, adds runtime, and generates real Parcelable implementations where supported.

Enforces explicit opt-in for global mutable state via RequiresGlobalState annotation; detects top-level and singleton mutables, offers configurable blacklist and Gradle integration.

Event and result observation with DataResult, LiveData/Flow wrappers, chaining/mapping/merge helpers and a Compose-first DSL for declarative loading, data, error and collection handling.

Lightweight wrapper around a file-IO implementation, fixing non-ASCII path handling, adding fluent path-building DSL, withFs execution block and Path-centric file operations (read/write/move/delete).

Per-object thread-local storage: ThreadLocal type supplies independent per-thread object copies; faithful line-by-line transliteration of upstream crate, port-lint provenance headers, feature-parity in-progress.

Provider-agnostic, self-hosted billing syncing payment events to Supabase as single source-of-truth; multi-provider plugins, CLI/AI setup, built-in paywall UI, dashboard and multi-tenant isolation.

Interactive canvas component enabling freehand and shape drawing with customizable background, stroke size, color/opacity, eraser, fill, eyedropper, spray, undo/redo, bitmap import/export.

Generates typesafe APIs from SQL statements, verifies schemas, statements and migrations at compile-time, and provides IDE autocomplete/refactoring plus multi-dialect SQL and labeled-query support.

Debug overlay embedding a floating panel to inspect HTTP traffic, view logs, toggle feature flags, manage typed preferences via codegen, and add custom debug screens—zero release overhead.

Versatile font toolkit converting variable fonts to static, transforming formats and querying font metadata; includes batch conversion and advanced glyph/variation handling.

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.

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.
