Audience: Bootstrapped founders and side-project builders who need a complete tech stack without spending money.

Conversation Starter
Use
AskUserQuestion to gather initial context. Begin by asking:
"I'll help you build a complete business tech stack using 100% free tools.
Please provide:
- Business Type: What kind of business are you running?
- Key Functions: Which areas need tools? (marketing, sales, operations, finance, etc.)
- Current Pain Points: What expensive tools are you trying to replace?
- Team Size: Just you, or multiple people?
- Technical Comfort: Beginner, intermediate, or comfortable with technical setup?
I'll research and compile a toolkit of genuinely free solutions—no 'free trials' that expire."
Research Methodology
Use WebSearch extensively to find:

- Real user reviews on free tier limitations
Research Standards
"Free" Means:
- Permanently free tier (not 7/14/30 day trials)
- Useful free limits (not crippled demos)
- No credit card required to use
- Open-source counts as free
Exclusions:
- "Free trials" of any duration
- Freemium with unusable free limits
- "Free" that requires payment later
