Mintlify versus Supabase valuation gap
$21.4M/year Vercel of developer docs
Supabase shows what happens when AI starts choosing the backend, not just helping write the app. Its jump to $170M ARR by May 2026 came from becoming the default place where agents and text-to-app tools create a database, auth, and storage in one step. That makes it a useful comparison for Mintlify, because both are winning by becoming machine friendly infrastructure inside the agent workflow, not just better tools for human developers.
-
Supabase monetizes a much heavier workflow than Mintlify. A developer or agent creates a live app backend on Supabase and then pays as that app stores data, handles logins, and serves traffic. Mintlify sits one layer earlier, helping agents understand which API or tool to pick in the first place.
-
Supabase growth is being driven by volume at the top of the funnel. Registered developers grew from 4M to nearly 10M, paying customers rose from 100K to 250K plus in seven months, and average revenue per customer stayed roughly flat near $700 per year. That supports a much larger revenue base than Mintlify today.
-
The multiple gap, roughly 62x for Supabase versus roughly 36x for Mintlify, reflects how investors price ownership of the runtime layer. If docs determine demand, the backend captures ongoing spend after launch. Supabase also turned potential rivals like Lovable and Bolt into channel partners through white labeled infrastructure, which deepens its distribution moat.
Going forward, the stack is likely to split into agent discovery and agent execution, with Mintlify helping agents choose tools and Supabase powering the app once chosen. If agent built software keeps compounding, Supabase is positioned to capture more of the recurring usage dollars, while Mintlify can keep expanding as the routing layer that sends that demand downstream.
