The Developer Tools Podcast with Fexingo: APIs, Infrastructure, and Software for Engineers

Lucas and Luna examine the developer tools landscape — APIs, infrastructure, and software designed for engineers — through the lens of business viability and technical merit. Each episode picks a specific tool or platform: how it was built, what problem it solves, who pays for it, and whether its architecture gives it a durable advantage. They compare pricing models, study public SDKs and changelogs, and trace the decisions that turn an open-source side project into a billion-dollar company. No demos, no tutorials — just two co-hosts reading documentation, running benchmarks, and asking whether a tool's design actually makes engineers more productive or just more dependent. Past topics: the economics of API gateways, why gRPC is replacing REST in microservices, the rise of WebAssembly beyond the browser, and the hidden costs of managed Kubernetes.
