Purely functional, highly asynchronous forum client handling network requests, session management and HTML parsing into strongly-typed DTOs, with async-first API and safe sealed-result handling.

Typed asynchronous clients for Twitch OAuth2, Helix REST API, EventSub WebSocket and IRC; stream-based auto-pagination, automatic EventSub reconnect/keepalive, pluggable token and logging.

Real-time HTTP and WebSocket traffic inspector with a premium UI, persistent notification launcher, advanced metrics dashboard, deep request/response inspection and automatic slow-endpoint detection.

Unified gRPC client offering a common API, channel builder with TLS, interceptors, generated stubs and protobuf serialization; supports unary and streaming RPCs, gRPC‑Web and native FFI.

Bootstraps translations from remote or bundled snapshot, persists local snapshots, serves cache-first reads with single-item fetch on miss, supports typed resources, Compose integration, background refresh.

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.

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.

Modular client SDK: unified networking, encrypted settings, security policies and MFA, multi-method identity and session management, WebSocket lifecycles, pluggable error parsers, composable UI and navigation.

Application-level networking layer offering typed NetworkResult, structured NetworkError, ordered interceptor pipeline (auth single‑flight refresh, retry, circuit breaker), redacted logging, converters, test doubles.

Headless, plug-and-play SDK offering networking, auth, HTTP cache, offline queue, logging, telemetry and MVI contracts; modular feature modules, dependency registry, and three integration paths including full offline-first with host SQL.

HTTP traffic inspector logging requests, responses, headers and bodies; supports mocking/overriding, HAR export, in-app UI, configurable filters, sanitization, retention and notifications.

Runs as an MCP server over stdio, implementing audio processing, subtitle‑to‑LRC and WAV→MP3 conversion, shell command execution, image understanding via Vision API, plus resource/prompt declarations.

Lightweight toolkit for Ktor HTTP clients: retry schedules with Retry-After parsing, per-request timeouts, etiquette headers, and destructive body-prefix sampling for diagnostics.

Compiles AT Protocol lexicons into typed classes, generates API interfaces and HTTP (Ktor) implementations, and supplies OAuth and Jetstream bindings plus a Gradle plugin for schema generation.

Resumable tus protocol implementation offering a client, embeddable server library, standalone runnable server jar, shared protocol primitives, and end-to-end integration tests.

Dynamic UI engine rendering native Compose widgets from JavaScript at runtime via QuickJS+Rust bridge; 40+ components, candlestick charts, reactive state, WebSocket realtime, cross-screen persistent store.

Chunked multipart uploads to cloud storage with pause/resume, retry and persistent upload state across restarts. Enqueued background engine, per-chunk progress stream, and pluggable HTTP callbacks.

Unified networking fabric with session API, swappable transports, replicated CRDT data structures, Raft consensus and leadership, turn-based game and fair-deal utilities, conformance tests.

Client for loops.so API with full endpoint coverage, typed resource groups, direct vs proxy modes to prevent shipping API keys, automatic 429 retries, configurable timeouts and logging.

In-app support chat backed by Supabase, real-time messages, media, emoji reactions, swipe-to-reply quotes, shared conversation state with agent console, and anonymous client sign-in.

HTTP-capture debug toolkit: Ktor interceptor, bounded event bus with ring-buffer, header redaction, in-app overlay (shake to open), and zero-install live web viewer streaming events.

Multiplatform IM SDK: unified network, sync, local DB and event layers with Wire-generated protobufs, Ktor client, SQLDelight, coroutines and catalog-driven Gradle dependency management.

HTTP inspection for Ktor, capturing requests, responses, headers and bodies, with UI, HAR export, request/response overriding, filtering, sanitization and configurable retention.

Local logging toolkit routing structured mobile SDK logs to a developer-hosted server; stores per-device/session JSONL, supports redaction, simple tail/curl inspection and agent workflows.
