Stack0

SaaS

A platform and SDK that combines email, CDN, video, screenshots, data extraction and AI workflows behind one API key, plus agents for building apps.

About Stack0

Stack0 is pitched as an autonomous product stack where AI agents build an app, deploy it, monitor it and operate it. Several parts make up the platform: Pylon, an open-source server for apps with schema, policies, authentication, live queries, server-side rendering and jobs, deployed with a single command to a cloud with a server per app, global CDN and scale to zero; agents that handle support, bookkeeping and scheduling within limits the owner sets; and cookie-free analytics.

The developer side is one SDK with eight managed APIs: transactional and marketing email, file storage and CDN, video streaming and transcoding, screenshots, webpage-to-JSON extraction, web crawling to markdown, multi-step AI workflows and more than 350 third-party integrations, all through one key and bill. SDKs cover TypeScript, Python and Go, and an MCP server with 41 tools, an OpenAPI 3.1 document and llms.txt make it usable by coding assistants. Idle services cost nothing.
