About ToolFusion
ToolFusion is an engineering tool network, not a generic calculator list.
- Structure. One navigation model everywhere: Domain → Category → Subcategory → Tool.
- Scope. 203 engineering domains across the ToolFusion network — 203 managed vertical sites, 0 external WordPress sites.
- Quality gate. Only tools that pass verification are published and linked; empty categories and dormant domains never produce dead pages.
- Relations. Cross-domain links follow an approved engineering affinity graph — no random interlinking.
