Top AI Agent Products and Frameworks | Generated by AI
Question: What are the best AI agent products, including Manus and others?
Answer:
AI agents are autonomous systems powered by large language models (LLMs) that can plan, reason, use tools, and execute complex multi-step tasks with minimal human intervention. As of late 2025, the field has matured significantly, with both ready-to-use products and frameworks standing out. “Best” is subjective and depends on use cases—such as personal productivity, enterprise automation, coding, or developer-built custom agents—but here are the most highly regarded ones based on reviews, benchmarks (e.g., GAIA), adoption, and expert discussions.
Top Ready-to-Use AI Agent Products
These are platforms or tools where you can deploy agents quickly, often with no/low code.
-
Manus AI: Widely praised as one of the most advanced general-purpose autonomous agents in 2025. Developed initially by a Chinese startup (Butterfly Effect/Monica), it excels at real-world tasks like web research, data analysis, report generation, coding, and browser automation. It uses a multi-agent architecture with models like Claude 3.5 and Qwen, showing high transparency (via a “Manus’s Computer” window). Strong performance on GAIA benchmarks; reviewers call it “mind-blowing” for autonomy. Note: Acquired by Meta in December 2025 for integration into their ecosystem. Great for complex, hands-off tasks.
-
Microsoft Copilot (and Copilot Studio): Reliable for productivity in the Microsoft ecosystem (Office, Teams). Allows building custom agents; strong enterprise adoption and reliability.
-
Salesforce Agentforce: Enterprise-focused, with pre-built agents for sales, service, and custom roles. Excellent for business workflows with guardrails.
-
OpenAI Operator / DeepResearch: Advanced research agent; autonomous web browsing and report synthesis. Part of broader OpenAI agent tools.
-
HubSpot Breeze: Integrated agents for sales/marketing automation within HubSpot.
-
Lindy: No-code platform for personal/business automation; highly rated for ease of use in everyday tasks.
-
Claude (Anthropic) with Computer Use: Features like desktop control make it strong for autonomous operations.
Top Frameworks for Building Custom AI Agents
These are developer-oriented tools to create your own agents.
-
CrewAI: Popular for multi-agent collaboration; easy to assign roles and orchestrate teams of agents.
-
AutoGen (Microsoft): Flexible for conversational multi-agent systems; great for complex workflows.
-
LangChain / LangGraph: Modular and widely used; excellent integrations and state management.
-
AutoGPT: Pioneering autonomous agent framework; still relevant for goal-oriented tasks.
Other notable mentions: Google ADK, Semantic Kernel, MetaGPT for specialized uses like coding teams.
In 2025, autonomous agents like Manus represent the cutting edge, shifting AI from chat-based to action-oriented. For most users, starting with Manus (if accessible via Meta) or Microsoft Copilot offers the best balance of power and usability. Developers prefer CrewAI or AutoGen for customization.
