Vercel Serverless Functions
Vercel Serverless Functions are a serverless compute platform that allows developers to deploy and run backend code (APIs, webhooks, etc.) without managing servers. They automatically scale with traffic, handle cold starts efficiently, and integrate seamlessly with Vercel's frontend hosting and deployment workflows. Functions are written in languages like JavaScript, TypeScript, Python, or Go and execute in isolated, secure environments.
Developers should use Vercel Serverless Functions when building full-stack applications on Vercel, as they provide a simple way to add backend logic without infrastructure overhead, ideal for APIs, form handling, or data processing in Jamstack sites. They are particularly useful for projects requiring rapid deployment, automatic scaling, and tight integration with Vercel's edge network for low-latency global performance.
