👁️
Human Readable
Typed plain text with readable structure — open it in any editor, diff it in Git, skim it at a glance. T-TOON stays indentation-first, while T-JSON stays bracket-friendly.
🤖
Agent Friendly
Stable, explicit syntax that LLMs and tooling can inspect, transform, and generate without bracket noise or type guesswork.
✨
Schema Free
No .proto, no .avsc, no IDL, no sidecar metadata. The payload is self-describing and travels as a single portable artifact.
Why TTOON?
Most serialization formats force a trade-off: human readability or machine precision. TTOON refuses that compromise.
- <code>Type fidelity</code> — Preserves decimal, date, time, datetime, uuid, and binary across language boundaries.
- Human readable — Plain text output that is easy to read, diff, and debug visually.
- High performance — First-class Apache Arrow and Polars integration with dedicated columnar fast paths.
- Cross-language — Identical behavior across Python, JavaScript, and Rust via a shared Rust core engine.
- Lightweight runtime — No full Node.js required; works in Vercel functions, Cloudflare Workers, etc.
Plain text, typed values
Every value carries its type — no schema file needed, no ambiguity at parse time.
