Free martech tool
Marketing stack manager
Document every platform in your marketing technology stack — CRM, analytics, ads, automation, and more. Track monthly license cost, share a link with stakeholders, and export a PDF when you need a client-ready deliverable.
What is a marketing stack manager?
A marketing stack manager is the system of record for your martech tools — not a spreadsheet that goes stale, and not a slide deck that only gets updated once a year. MarStack gives you categories (CRM, CMS, analytics, ads, lifecycle messaging, and more), tool notes, monthly price fields, and shareable output so marketing, ops, and agencies stay aligned.
Why teams use MarStack
- Map your martech stack by category with sensible defaults for HubSpot, GA4, GTM, and more.
- Track monthly cost per tool — built for upcoming stack spend and overlap analysis.
- Share a link so clients or leadership can view the stack without an account.
- Export PDF or CSV for QBRs, audits, and agency onboarding.
- Pair with Site Audit to see whether tags on your site match what you documented.

Is this a marketing stack manager or a spreadsheet?
Spreadsheets work until they do not — version chaos, no categories, no share links. MarStack is purpose-built to document a marketing tech stack with structure, cost fields, and exports.
Who is this for?
Marketing ops, demand gen, agencies, and founders who need a clear picture of CRM, analytics, ads, automation, and integration tools — especially before a replatform, audit, or budget review.
Does it cost anything?
The stack manager is free to use. Create an account to save your stack to a team workspace.
