Solution Stack — best tool per component

The opinionated pick for each job, plus alternatives and when to switch. Drawn from what both communities actually teach and use (AOA runs Claude (incl. Claude Design, ex-Gamma) + Zoom/Fathom + cal.com + Notion + Retell + Zapier; AAIC adds n8n + GoHighLevel + Upwork/LinkedIn/Heyreach + cold-email infra).

Two guiding principles: 1. Integrate best-of-breed OSS/SaaS; don’t rebuild. (business-os strategy.) 2. Verify price & features “current as of today” before every recommendation. Tool pricing and features drift; this is the version-drift safeguard (AOA AI-Powered Analysis). Prices below are directional, not quotes.

Files: - stack-table.md — the full component → recommended tool → alternatives → why table. - two-delivery-stacks.md — the two reference architectures (all-in-one vs. composable) and how to choose. - client-one-pager.md — the leave-behind one-pager template for prospects.
