What is Ovrin?

Ovrin is a cloud-based computing platform specifically designed for developers engaged in creating AI agents and software that need to run in controlled environments. The platform allows users to utilize a REST API, Python, and TypeScript SDKs or an MCP server to create temporary Linux sandboxes, execute shell commands, manage stateful code, handle files, configure scoped API keys, and retrieve execution results. It also includes prebuilt configurations like Claude Code, OpenAI Codex, Gemini CLI, and DeepSeek Harness, while offering browser workflows that work seamlessly with Chrome and Playwright. Furthermore, Ovrin incorporates features such as persistent memory, lifecycle controls for sandboxes, usage analytics, and concurrency limitations. Typical use cases for Ovrin involve running coding agents, automating browser-based tasks, and executing code produced by various models. Importantly, the platform provides a free tier, with multiple paid plans available that enhance concurrency and compute costs based on usage. In essence, Ovrin is designed to facilitate and optimize the development of AI solutions by delivering a dynamic and adaptable environment for developers. Additionally, its user-friendly interface and comprehensive features make it an appealing option for both novice and experienced programmers alike.

What is 21st?

21st is a developer-focused platform designed to simplify the creation and deployment of AI agents within modern software applications. The platform provides an SDK that allows developers to define agents using simple code while integrating tools, prompts, and AI models. It supports multiple development environments and frameworks including Next.js, React, TypeScript, Python, Node.js, and other common programming stacks. Developers can configure agents to run on advanced runtimes such as Claude Code or Codex, enabling tool usage, file access, and intelligent task execution. Once the agent configuration is defined, deployment can be completed using a single command that automatically sets up infrastructure. The platform manages backend systems such as sandboxed execution environments, authentication, rate limits, and streaming responses. It also includes a drop-in chat interface component that developers can embed directly into their applications to enable user interaction with agents. Real-time token streaming allows users to see responses generated progressively, creating a more interactive experience. The platform provides built-in observability tools that allow developers to monitor conversations, replay sessions, and trace agent actions. These features make debugging and optimization much easier during development and production. 21st also includes usage controls such as per-user spending limits, quotas, and metering to help manage AI costs. By combining powerful developer tools with managed infrastructure and deployment capabilities, 21st makes it easier for teams to build and scale AI-powered agents within their products.
