Tersa is an open-source visual AI playground built as a Next.js web application where users drag, drop, and connect nodes on a canvas to build AI workflows. It supports text, image, and video models from 25+ providers via the Vercel AI SDK Gateway, with streaming responses and cost indicators.

Use cases

  • build ai workflows visually without writing code
  • compare outputs from different llm providers side by side
  • prototype multi-step ai pipelines on a node canvas
  • test image and video generation models in one place
  • estimate relative costs of different ai models
  • chain prompts and models together with drag-and-drop nodes

When to choose

  • you want a visual, node-based canvas for experimenting with AI models
  • you need access to many model providers through a single gateway
  • you want a self-hostable alternative to closed AI workflow tools
  • you prefer streaming responses and reasoning visibility while prototyping

When to avoid

  • you need production-grade workflow orchestration with scheduling and retries
  • you want a headless API or CLI rather than a browser-based canvas
  • you need offline operation without provider API keys
  • your workflows require non-AI data transformation steps
