Nyxis — Open massive structured datasets in the browser

Stream, filter, and explore GB-scale structured data without JSON hydration bottlenecks.

Nyxis compiles human-readable .nxs to memory-mapped .nxb for browser-native workloads: virtual scroll, streaming ingest, and selective field reads — without JSON.parse() on the full export.

Why JSON breaks

• V8 string limits on multi-hundred-MB payloads
• AST heap inflation and UI freezes
• Full hydration before first interaction
• Silent integer truncation above 2^53−1

Proof

• Log explorer — millions of rows, live telemetry
• Browser benchmarks — time to interactive, memory, filter latency
• 5-minute quickstart

How it works

Zero-copy reads, tail-index seeks, streamable v1.2 sealing, row / columnar / PAX layouts. Full depth: use cases, BENCHMARK.md, SPEC.md.
