This text discusses the debate between building and buying product integrations, with a focus on whether to create them in-house or purchase third-party solutions. The author argues that while both options have their benefits and drawbacks, a new category of solution called "product integrations infrastructure" can provide the best of both worlds by combining flexibility and scalability with efficiency and speed. This solution is exemplified by Nango, which offers pre-built templates, built-in tooling and infrastructure for customization, and access to Enterprise API experts, among other features. The author concludes that the decision to build or buy integrations depends on context, team capacity, goals, and the importance of integrations to the product, and suggests considering a solution like Nango as an alternative to traditional in-house development or third-party purchases.
