Subshack - See which Substack Notes actually bring you subscribers
by•
Likes are not subscribers. Subshack shows which of your Substack Notes and posts actually bring people in, counted in people rather than percentages, and audits any profile out of 100. Audience and Opportunities show the readers worth answering; Campaigns and welcome messages reach them on your terms — nothing is sent until you press start. Free on Chrome and Firefox.

Hey Product Hunt 👋 I’m Karim, maker of Subshack.
I built Subshack after realizing that Substack shows you views, likes and subscribers, but makes it surprisingly hard to understand what is actually driving your growth.
Subshack is a browser-first growth toolkit for Substack creators.
It helps you:
• See which Notes and articles actually bring subscribers
• Understand reach and audience health
• Find growth opportunities and profile issues
• Segment your audience and identify your most engaged readers
• Use free tools to audit your profile and uncover audience growth opportunities
Privacy was important to me too: your Substack session stays inside your browser and isn’t sent to Subshack’s servers.
I’ve been building this while growing my own Substack and using the data from those experiments to improve the product.
Today I’d especially love feedback from other Substack creators.
I’m shipping fast, so what I learn today will directly influence what I build next.
What’s the one thing you wish Substack analytics told you but currently doesn’t?
