Build production agents with harness and sandbox
The OpenAI Agents SDK is a cutting-edge development toolkit designed for creating sophisticated AI agents capable of performing complex, long-horizon tasks. It introduces a model-native harness and a native sandbox environment, enabling developers to build agents that can safely inspect files, execute commands, and run code across various cloud providers like E2B, Modal, Daytona, and Vercel. This makes it ideal for AI developers seeking to integrate safe, scalable, and versatile agent functionalities into their applications. Its emphasis on sandboxed execution and provider integration ensures that developers can experiment and deploy with confidence, minimizing risks while maximizing flexibility. The SDK’s focus on production-ready agents sets it apart by providing robust tools for real-world AI deployment and automation scenarios.
Pros
- Supports safe sandboxed execution for testing and deployment
- Built-in integration with multiple cloud providers for flexibility
- Enables long-horizon, complex task execution
- Model-native harness simplifies development workflows
- Facilitates inspection and command execution within agents
Cons
- Still relatively new, with limited community adoption
- May require advanced technical skills to utilize fully
- Pricing and detailed features are not explicitly disclosed
Best for
- • Building autonomous AI agents for data inspection and analysis
- • Automating complex workflows involving file handling and command execution

Any website. We deliver the API.
Anything API is an innovative platform that bridges the gap for websites lacking public APIs. It empowers users to convert their browser-based interactions into robust, production-ready APIs without extensive coding. By simply describing the task, users can have custom functions built that directly call the target website, enabling seamless integration and automation. These custom API endpoints can be deployed serverless, scheduled via Cron, or accessed through standard API calls, making it highly versatile for developers, automation enthusiasts, and businesses seeking to extend functionality of web services. Its unique approach of translating manual browser work into programmable endpoints distinguishes it from traditional API providers, offering a flexible solution for accessing data or automating tasks on virtually any website.
Pros
- Transforms any website into a custom API without coding
- Flexible deployment options including serverless and scheduled tasks
- User-friendly task description process simplifies API creation
- Supports automation and integration with existing systems
- Highly versatile for various web scraping and data extraction needs
Cons
- Limited details on pricing structure and plans
- Potential challenges with highly dynamic or complex websites
- Reliance on agent-generated functions may require occasional updates
Best for
- • Extracting data from websites lacking public APIs
- • Automating repetitive browser tasks through API calls
- • Building integrations for custom web workflows
- • Monitoring website changes or content updates
