What are Node-RED and Skyvern?
Node-RED
Node-RED is a flow-based development tool for wiring together hardware, APIs, and online services with a browser editor. It targets makers and integrators, especially in IoT. It is deployed via Docker or npm.
- Browser-based flow editor
- Thousands of community nodes
- Strong IoT and MQTT support
- Lightweight runtime
Skyvern
Skyvern automates browser-based workflows by combining large language models with computer vision, allowing it to operate on websites it has never seen before. It runs as a self-hosted service with an API.
- LLM-driven browser automation
- Works on unseen sites
- Vision-based interaction
- Workflow API
