Stamplay

Stamplay was a backend-as-a-service and API-integration platform — billed as "Lego for developers" — founded in 2012 (Turin, Italy; later San Francisco) and backed by 500 Global. It let developers assemble application backends by visually wiring together third-party APIs, authentication providers, hosted data objects, webhooks, and static site hosting on stamplayapp.com, driven by a JavaScript SDK, a Node.js SDK, and the `stamplay` CLI. The product has been discontinued: the company was acquired (widely reported as Apple, 2019), the stamplay.com domain is now held via MarkMonitor and returns no HTTP response, every source repository in the GitHub organization is archived, and the npm SDK/CLI packages were last published in 2016. This API Evangelist profile preserves the historical developer footprint (SDKs and CLI) rather than a live API surface.

Stamplay is profiled on the APIs.io network. Tagged areas include Company, Backend as a Service, API Integration, Low Code, and Developer Tools.

Stamplay’s developer surface includes CLI and 4 more developer resources.
