Fullstack Solution Template For Agentcore

Fullstack AgentCore Solution Template (FAST)

_Author's note: for the official name for this solution is the "Fullstack Solution Template for Agentcore" but it is referred to throughout this code base as FAST for convenience._

The Fullstack AgentCore Solution Template (FAST) is a starter project repository that enables users (delivery scientists and engineers) to quickly deploy a secured, web-accessible React frontend connected to an AgentCore backend. Its purpose is to accelerate building full stack applications on AgentCore from weeks to days by handling the undifferentiated heavy lifting of infrastructure setup and to enable vibe-coding style development on top. The only central dependency of FAST is AgentCore. It is agnostic to agent SDK (Strands, LangGraph, etc) and to coding assistant platforms (Q, Kiro, Cline, Claude Code, etc).

FAST is designed with security and vibe-codability as primary tenets. Best practices and knowledge from experts are codified in _documentation_ in this repository rather than in _code_. By including this documentation in an AI coding assistant's context, or by instructing the AI coding assistant to leverage best practices and code snippets found in the documentation, delivery scientists and developers can quickly vibe-build AgentCore applications for any use case. AI coding assistants can be used to fully customize the frontend and the infrastructure, enabling scientists to focus the areas where their knowledge is most impactful: the actual prompt engineering and GenAI implementation details.

With FAST as a starting point and development framework, delivery scientists and engineers will accelerate their development process and deliver production quality AgentCore code following architecture and security best practices without having to learn any frontend or infrastructure code.
