Spec-first, not marketing fluff
Every entry is built around the parameters engineers actually compare: range, accuracy, output signal, protection rating, materials, compiled from manufacturers' public specifications and kept current.
About
SpecForge / Founded 2024
Shanghai
The spec-first encyclopedia for
industrial buyers and engineers.
Stop digging through PDF catalogs, supplier emails, and mismatched ERP material masters. SpecForge turns that scattered product data into one searchable, comparable reference: find parts by exact specification, compare models side by side, and reach verified manufacturers in minutes, not days.
Mission
Consolidate global manufacturer specifications into a single trustworthy, searchable, comparable encyclopedia, so procurement professionals and design engineers spend less time hunting datasheets and more time deciding.
By the numbers
694 product category guides · 11 major industrial sectors · English-first (中文 / العربية planned) · founded 2024 in Shanghai Zhangjiang.
WHAT WE DO
Built for the way engineers actually compare parts.
Not another directory. SpecForge pairs industrial domain knowledge with a modern data, content, and AI stack, so the reference stays accurate, current, and impossible to miss when you search.
AI scale, human accuracy
Our pipeline drafts selection guides, comparison tables, and FAQs with an AI writing system, then automated fact and quality gates check every draft before it publishes, with human spot audits. Coverage that scales without guessing.
Built to be found and cited
Structured data, clean canonical URLs, an llms.txt for AI crawlers, and passage-level citable writing mean our pages rank in classic search and get cited by ChatGPT, Perplexity, and Google AI Overviews.
Neutral by design
We never sell search position. Results are ordered by relevance and recency; paid placement changes a display badge only, never who ranks first.
COVERAGE
694 product category guides across the sectors engineers source from.
We index product specifications from public manufacturer catalogs across eleven industrial sectors, and the library grows every week.
