Tiny runtime JSON config manager for fetching, caching and resolving application settings with conditional overrides, scheduled activation, string/semver matching and a client for automated retrieval.

Embeddable decision-flow engine for onboarding, questionnaires and assessments; separates logic from presentation, emits renderable states from JSON-defined flows, offers theming or fully custom UI integration.

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

Schema compiler and runtime for protobuf: generates strongly-typed message models, handles binary encoding/decoding, offers Moshi/Gson JSON adapters, and supports Okio relocation for compatibility.

Extracts main article content and metadata from web pages into cleaned HTML/text, offers configurable parsing, readerability checks, JSON-LD handling, and serializer customization.

Serializable representation of symbol-processing models, enabling portable model snapshots, JSON serialization, parity-preserving model exchange, and straightforward publishing of generated metadata for tooling and analyses.

Streaming JSON parser emitting flat token events for incremental, chunked input; supports suspending reads, building or skipping value trees, and efficient selective field extraction.

Geospatial toolset: GeoJSON DSL with builders and JSON serialization, ported Turf.js spatial-analysis functions, plus unit-of-measure types and formatting utilities for distances.

Generate JSON Schema documents from data types, honoring serialization attributes, offering derive-style macros, schema-from-value generation, serde-compatible behavior, and Draft 2020-12–compliant output.

Easy-to-use seccomp-bpf jailing library; define filters via JSON or code, compile to BPF, and install runtime or build-time with rule-based conditions and actions.

Build typed property views over raw object maps, decode on-demand, edit known fields, and re-emit preserving unknown fields. Supports JSON/YAML delegates, slices and null-write modes.

Derives OpenAI function-tool schemas from serialization descriptors, turning sealed request hierarchies into SDK tool declarations and decoding model function calls into typed request objects.

Client for interacting with app API: request/response handling with JSON, file and form inputs, collection-format queries (csv/tsv/ssv/pipes), numerous domain models (payments, chat, AI) and bearer auth.

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.

Represents tri-state fields—absent, explicitly null, or present with value—ideal for PATCH/partial updates; serializes to natural JSON shape and supplies helpers to apply and inspect patches.

Tiny decimal arithmetic API for precise monetary and exchange-rate values avoiding binary floating point; supports parsing, formatted I/O, 38-digit decimal context, rounding, base-unit conversions, serialization.

Typed JSON-RPC client for codex app-server: coroutine-driven session with response correlation and notification flows, high-level typed APIs, stdio/websocket transports, schema generation and testing tooling.
