Playground

The Twilic Playground is a browser app for comparing encoded sizes without installing anything locally.

What it shows

Two views are available:

1. Encoded sizes — the same fixture payloads as the benchmark harness. Compares Twilic against MessagePack, CBOR, BSON, and JSON (UTF-8).
2. Schema-first — compares Twilic Bound profile (encodeWithSchema) with Protobuf, Avro, FlatBuffers, and Apache Arrow IPC on schema-example style records.

You can also paste custom JSON (a root object or array) to see how your own payload compares.

When to use it

• Explore size savings on realistic fixtures before adopting Twilic.
• Compare schema-less and schema-first encoding side by side.
• Share a quick visual demo with teammates who do not have SDKs installed.

For throughput numbers (encode/decode ops per second), use the benchmark harness or twilic bench. The playground runs @twilic/core in WASM inside the browser; the benchmark suite uses Node.js N-API by default, so timing numbers are not directly comparable.

Run locally

The playground depends on a sibling twilic-js checkout:

your-workspace/
  twilic-js/
  twilic-rust/
  playground/

cd ../twilic-js
pnpm install
pnpm build:wasm
pnpm build:ts

cd ../playground
pnpm install
pnpm dev

Opens at http://localhost:5173.
