Flowise is an open-source agentic development platform designed to help teams build AI agents and LLM-powered applications using a visual workflow interface. The platform allows users to design intelligent workflows through modular components that can be combined to create chatbots, automation systems, and autonomous AI agents. Developers can build both single-agent chat assistants and multi-agent systems that collaborate to complete complex tasks. Flowise integrates with more than 100 large language models, embedding models, and vector databases, providing flexibility in selecting AI technologies. The platform also supports retrieval-augmented generation (RAG), enabling applications to retrieve knowledge from documents and data sources. Built-in features such as human-in-the-loop workflows allow users to review and validate agent actions before execution. Observability tools provide detailed execution traces and compatibility with monitoring systems like Prometheus and OpenTelemetry. Developers can integrate Flowise with existing applications using APIs, SDKs, or embedded chat widgets. The platform supports both cloud and on-premises deployment environments for enterprise scalability. By providing visual tools and flexible integrations, Flowise accelerates the development and deployment of advanced AI-driven applications.

Sprites.dev offers a cloud-based infrastructure platform that delivers persistent, hardware-isolated Linux environments capable of executing arbitrary code in a safe and efficient manner. Each “Sprite” operates as a fully functional virtual machine that can be spun up in mere seconds, providing developers with immediate access to a ready-to-go environment that includes root access and a comprehensive filesystem. Unlike conventional containers or serverless functions, these environments are stateful, ensuring that all installed packages, files, or configurations are preserved between sessions, allowing users to seamlessly continue their work from the last point they left off. When inactive, Sprites automatically enter a hibernation mode and can be resumed on demand, preserving their state while enhancing resource efficiency. The platform also features checkpoint and restore capabilities, which enable users to swiftly save and revert entire system states; this functionality is particularly beneficial for experimentation and iterative development. Furthermore, the ability to create multiple Sprites simultaneously allows developers to test various scenarios concurrently, greatly enhancing productivity and flexibility in their workflows.
