Alion vs BuiltWith for tech stack data
BuiltWith detects technologies from what a website loads: scripts, tags, hosting. Alion reads them from what companies require in the jobs they have open. The two answer different questions: what runs on the homepage, and what the teams work with and are hiring for now. Alion also returns the number of open roles that need each technology.

When each fits
- Website technologies (analytics, ad tags, e-commerce platforms, CDNs): a website scanner
- Back-end and data technologies (warehouses, orchestration, languages, cloud services) and who is hiring for them: job requirements
- Timing: a technology appearing in new requirements means a team is building around it now
