Workflow Blocks

Explore the ecosystem of Blocks you can use in a Workflow.

Workflows are made up of Blocks. You can connect multiple Blocks together to build computer vision applications.

In this section of the Roboflow documentation, we will cover:

1. What each Block does

2. How to use each Block

3. When a Block may be useful

4. The response returned by a Block

This section is intended as reference as you build a Workflow. We encourage you to come here whenever you have a question about how to use a particular Block in the Workflows editor.

Several categories of Blocks are available:

Category	Descriptoin
Models	Run a fine-tuned or foundation model.
Visualizations	Visualize the output of a model.
Logic and Branching	Control the flow of your Workflow.
Data Storage	Save data in a Roboflow dataset or an external database.
Notifications	Send an alert, such as an SMS message or email.
Video Processing	Analyze the contents of videos with tracking algorithms, time in zone analysis, and line crossing checks.
Transformations	Manipulate image and prediction data.
Classical Computer Vision	Run classical computer vision tasks, such as edge deteciton, template matching, and size measurement.
Enterprise	Connect Roboflow to your Enterprise systems, such as using MQTT or Modbus TCP.
Advanced	Advanced blocks for specific use cases, like PASS/FAIL analysis, data caching, and embedding similarity.
Custom	Make and run custom blocks with Python
