Map your marketing stack — free
You can't fix what you can't see. Document every platform in your martech stack — CRM, analytics, ads, automation, and more — then spot the gaps, overlaps, and missing connections that break your data. When you're ready to fix what's behind the map, we're here.
Why map your stack first?
Most marketing data problems start with a stack nobody fully understands. Tools get added, nobody documents the integration, and six months later GA4 doesn't match HubSpot. A marketing stack manager is step one — the system of record that shows what you have, what it costs, and where the gaps are. MarStack built this tool free because we see the same broken patterns on every audit.
What you get — free
- Map by category — CRM, CMS, analytics, ads, automation, with defaults for HubSpot, GA4, GTM, and more.
- Track monthly cost per tool — spot overlap before renewal season.
- Share a link or export PDF — for QBRs, budget reviews, or agency onboarding.
- Pair with AI Readiness Audit — see if AI systems would understand and recommend your business, plus marketing tech and performance in one scan.
- Talk to us when you're ready — MarStack fixes the tracking, integrations, and data pipelines behind the map.

Is MarStack a software company or an agency?
Both — in the right order. MarStack is a marketing data agency that fixes tracking, builds websites, and connects your stack. We built free tools like the stack manager and site audit because they're the same diagnostics we run on every client engagement.
Who is this for?
Marketing ops, demand gen, agencies, and founders who need a clear picture of their martech — especially before a replatform, audit, budget review, or when something in the data just doesn't add up.
What if the map reveals problems?
That's the point. When you see missing integrations, undocumented tools, or tags that don't match your stack — book a call and we'll help you fix the data behind the map.
