NBT Generator

The NBT Generator converts declarative tag definitions into valid Named Binary Tag payloads. It targets developers, modders, and tooling engineers who need deterministic data for servers, simulations, and testing. By describing the tag tree in a structured format, users avoid manual byte-level encoding and streamline validation.
Core logic: Each tag definition includes a name, a type, and a value, with support for nested compounds and lists. Primitive types include byte, short, int, long, float, double, string, and arrays. The tool enforces type safety, range checks (e.g., byte -128..127; int -2147483648..2147483647), and length limits for strings and arrays. Optional templates enable repeated structures and batch generation.
Outputs: The primary artifact is a binary NBT payload; alternate outputs include base64 and a JSON-like tree for tests. Users can export to files or feed results into CI pipelines. The tool runs fully client-side or offline, preserving privacy and enabling repeatable builds.
Use cases and differentiators: It provides deterministic results, strict type checking, and clear error reporting without server round-trips. Unique value lies in schema-driven generation, nesting support, and easy export for development workflows, data-driven prototyping, and mod creation.
