Zaltech
Framework, SDK

A full-stack framework for building AI-native, cross-provider applications that run across ChatGPT, OpenAI, Gemini, Claude, and future MCP-compatible platforms. It standardizes how you build tools, UI, and integrations on top of the Model Context Protocol (MCP) and ChatGPT Apps SDK / Apps SDK UI—so you stop rewriting the same glue code for every provider and every app.
Zaltech provides a unified, standards-aligned developer surface that eliminates fragmented provider SDKs, custom MCP servers per project, and one-off UI bridges. It features a feature-based architecture where every capability is a vertical slice (tool + logic + UI), with built-in authentication, observability, and one-command deployment.
The framework includes native AI UI system with production-grade widgets, interactive UI over MCP using React and Remote DOM, streaming-first transport with SSE, and MCP Inspector for visual testing. It enables building ChatGPT Apps, Gemini Extensions, Claude MCP Tools, and all kinds of AI Native Apps from the same codebase.
