Why Unkey Ditched TypeScript and Serverless for GO!

In this episode of the Modern Web Podcast, host Danny Thompson and co-host Adam Rackis chat with James Perkins, CEO of Unkey, an open-source API management platform built for scale, security, and developer simplicity. James shares the challenges of building globally distributed infrastructure, and why his team ditched serverless and TypeScript in favor of Go and servers.

They talk candidly about the realities of API management at scale, how Unkey balances open source transparency with enterprise-grade performance, and what it takes to build developer trust—both as a brand and as a product.

Keypoints from this episode

• Unkey simplifies API management by acting as middleware for authentication, rate limiting, and security—without requiring deep backend expertise. It's designed for developers to go from idea to production with minimal setup.

• Go over serverless – James and his team initially explored TypeScript and serverless architecture but ultimately returned to Go and servers for better performance, scalability, and developer experience at scale.

• Open-source transparency is core to Unkey’s philosophy – The entire codebase is public, and the team maintains a radically open company culture, where even investor updates and customer support emails are shared internally.

• Customer obsession drives every decision – Regardless of whether a user is paying $0 or $2,000/month, Unkey responds quickly, prioritizes community support, and encourages a culture of ownership and responsiveness across the team.
