Basic Information

Flyde is an open-source toolkit that brings visual AI workflows into an existing TypeScript/JavaScript codebase. It provides a visual extension of TypeScript to prototype, integrate, evaluate and iterate on backend AI logic such as prompt chains, API orchestration, agentic workflows and custom backend services. The project includes a VS Code extension and runtime libraries designed to run flows inside your repository and CI/CD pipelines, enabling development and debugging without leaving the codebase. The repository contains core runtime packages and node loaders under permissive MIT terms while the UI editor components are AGPLv3. The project offers a browser playground and a CLI bootstrap command to create new Flyde apps, and it documents telemetry behavior and opt-out options for the VS Code extension.

App Details

Features
Flyde offers a VS Code extension for designing flows visually and a runtime library that executes flows inside your existing TypeScript project. Features highlighted in the README include TypeScript support, integration with existing backend frameworks, a rich standard library of nodes, a visual debugger, and a loader system for flow files. Distribution includes @flyde/core, @flyde/loader and @flyde/nodes with MIT licensing for runtime components and AGPLv3 for UI libraries. There is a playground to try Flyde in the browser, and a CLI command to scaffold apps. The extension collects anonymous usage telemetry by default with documented opt-out controls. The project supports collaboration between technical and non-technical team members via visual representations of backend logic.
Use Cases
Flyde helps teams prototype and maintain AI-heavy backend logic by making complex workflows visible and editable inside the codebase. Developers can build and debug prompt chains, agents and API orchestration while keeping full access to runtime code and backend frameworks. Product managers, designers and other non-developers can contribute through a shared visual interface, lowering collaboration barriers. Because flows run in your repository and CI/CD, Flyde supports production integration and iterative development rather than isolated tooling. The visual debugger and standard node library simplify troubleshooting and reuse. The mix of permissive runtime licensing and an editor that must be open-sourced under AGPL clarifies integration and distribution constraints for teams.
