LyinWebTools

LyinWebTools owns traditional/core tool discovery.

LyinWebTools is the primary child module of the LyinTools parent suite, owning traditional and core web utility tool families. Runtime now presents catalogue posture only; product-specific execution, APIs, workers, and routes belong to the independently deployed LyinTools application.

Stage-active child module

LyinWebTools remains visible through governed catalogue records. The Runtime main site does not expose local execution routes, provider integrations, API keys, workflow dispatch, or product-specific billing flows for LyinTools.

Product scope

Traditional and core utility families under LyinWebTools.

Every tool family below belongs to LyinWebTools. PDF tools, domain tools, host tools, mail tools, and repo tools are separate sibling modules under LyinTools.

Calculators

Mathematical computation helpers
