AgentGPT — Autonomous AI Agent in Your Browser

Introduction

AgentGPT is a browser-based platform for assembling and deploying autonomous AI agents. Unlike CLI-only agent tools, it provides a polished web UI where users define a goal in natural language and watch the agent decompose it into tasks, execute each step, and refine results in a loop.

What AgentGPT Does

• Accepts a high-level goal and autonomously breaks it into subtasks
• Executes tasks sequentially, feeding outputs from one step into the next
• Runs entirely in the browser with a React frontend and Next.js backend
• Supports multiple LLM providers including OpenAI and open-source models
• Allows saving, sharing, and replaying agent runs

Architecture Overview

AgentGPT follows a Next.js full-stack architecture. The frontend presents a chat-like interface where agents stream their reasoning. The backend orchestrates a task loop: it sends the current goal and completed steps to the LLM, parses the response into new tasks, and continues until the agent determines the goal is met or a maximum iteration count is reached. Prisma handles database persistence for user sessions and saved agents.

Self-Hosting & Configuration

• Clone the repo and run the setup script, which provisions Docker containers for the app, database, and backend
• Set OPENAI_API_KEY in the .env file for the default provider
• Configure NEXT_PUBLIC_BACKEND_URL if hosting the backend on a separate machine
• PostgreSQL is used for persistence; connection details go in DATABASE_URL
• Optional: connect alternative LLM endpoints by updating the provider configuration

Key Features

• No-code agent creation through a clean web interface
• Real-time task streaming shows agent reasoning as it works
• Agent templates for common goals like research, coding, and analysis
• Session persistence lets you pause and resume agent runs
• Open-source and self-hostable with full control over data

Comparison with Similar Tools

• AutoGPT — CLI-first with plugin ecosystem; steeper setup curve
• BabyAGI — minimal task-driven agent; no built-in UI
• CrewAI — focuses on multi-agent role orchestration rather than single-agent loops
• SuperAGI — more infrastructure-heavy with marketplace; heavier deployment

FAQ

Q: Which LLMs does AgentGPT support? A: It supports OpenAI models by default. You can configure alternative providers by modifying the backend LLM configuration.

Q: Is there a hosted version? A: The project previously offered a hosted demo at agentgpt.reworkd.ai. Check the repository README for current availability.

Q: How do I limit agent iterations? A: Set the maximum loop count in the settings panel or via the MAX_LOOPS environment variable to prevent runaway execution.

Q: Can agents access the internet? A: Agents can use web search tools when configured, but by default they rely on the LLM's knowledge without live browsing.
