Integer compression that actually fits your data

SlidPhiLabs ships pure-JavaScript lossless codecs for integer sequences: Zero Range Wave (beats gzip/brotli on zeros, ramps & walks), the Blackjack family, and Omni-Dormant pathway codecs. Code is free. Paid support is optional.

Zero Range Wave (ZRW) v5

Specialized pure-JS integer-sequence compressor — library, HTTP API (zrw-api), and MCP (zrw-mcp). Built for repetitive and smooth integer streams where generic compressors waste bits.

Support & integration

MIT covers using the open packages. Paid offers are time and guidance — not a second license for the same rights. ZRW has its own commercial tiers (see above).
