Executive Summary
Durable, an AI-powered platform for entrepreneurs to launch and manage businesses, has migrated its entire multi-tenant infrastructure from a self-hosted solution to Vercel. The move was driven by the need to eliminate the complexities of managing infrastructure at scale, which distracted their small engineering team from core product development. By leveraging Vercel, Durable solved critical challenges in both web hosting and AI operations, enabling them to focus on creating value with AI agents, ship new features faster, and significantly reduce operational costs.
Key Takeaways
* Core Problem: Self-hosting a multi-tenant platform for millions of businesses created significant infrastructure overhead related to custom domains, SSL, multi-region clusters, security, and cost attribution.
* AI-Specific Challenges: As Durable integrated AI agents, new problems arose, including complex model orchestration, the critical need for tenant isolation to prevent data leakage, and a lack of per-customer AI cost visibility.
* Solution & Migration: The company migrated its entire stack to Vercel, performing a full rewrite of their product accelerated by coding agents. This allowed them to replace their self-hosted infrastructure entirely.
* Business Impact: The migration resulted in a 3-4x reduction in infrastructure costs compared to their previous self-hosted setup.
* Operational Efficiency: With a team of six engineers and no DevOps, Durable now ships new production AI agents in a single day, serves over 3 million businesses, and processes approximately 1.1 billion tokens daily.
Strategic Importance
This migration allows Durable to focus its lean resources on its core differentiator—AI agents—instead of infrastructure management. For Vercel, this case study showcases its platform as a viable, cost-effective solution for complex, AI-native applications, positioning it as a strong alternative to traditional cloud providers.
