Firma.dev and Vercel Drop are two very different products that serve distinct needs in the developer ecosystem. Firma.dev is a developer-first e-signature API designed for SaaS platforms to embed document signing workflows at a fraction of the cost of traditional providers. Vercel Drop, on the other hand, is a deployment tool that lets you instantly publish static sites and frontend projects by simply dragging and dropping files into your browser.
