TanStack AI
Framework-agnostic TypeScript AI SDK; 1.0 stabilizes core APIs with 23 provider adapters, while the agent harness stays experimental.
Overview
TanStack AI reached 1.0 on October 23, 2026, committing to stable core APIs across the @tanstack/ai* packages. It ships 23 provider adapters plus an openaiCompatible adapter, UI bindings for React, Vue, Solid, Svelte, Preact, Angular and vanilla JS, and features including subagents, a decide() helper, portable Agent Skills, compaction, computer use, automatic prompt caching and a unified Files API. It can expose tools as an MCP server and supports sign-in with ChatGPT, GitHub Copilot or OpenRouter. The agent harness (@tanstack/ai-harness) remains experimental on 0.x, and the React, Solid and Vue UI packages were removed with no 1.0 release.
This is a sourced directory entry. Features and capabilities are reported in the linked sources; this entry does not document independent Aymorphic testing.

- Subagents, decide(), portable Agent Skills, compaction and computer use
- createMCPServer and WebMCP support; 11 sandbox providers
- Integrations with Claude Code, Codex, OpenCode, Grok Build and ACP agents
- Experimental agent harness on 0.x; @tanstack/ai-react-ui, -solid-ui and -vue-ui removed
Use cases
- Building AI chat and agent features in TypeScript apps without locking into one model vendor
