The record

Purpose: FRED is an open-source visual regression tool for automatically comparing baseline and updated website instances.
Checks: It compares console and network logs, screenshots, and optionally screenshots using machine-learning analysis.
Visual AI: Its image-segmentation analysis identifies high-level text and image structures to reduce false positives from dynamic content.
Scalability: FRED has an internal queue and can process websites in parallel depending on available RAM, CPUs, or GPUs.
Interfaces: Users interact with FRED through a web UI or API.
Workflow: A comparison starts with two URLs, which FRED crawls to find pages to render and compare.
Results: Results are saved locally and include divergence scores and links to raw and analysis images.
Deployment: The repository documents running FRED as a Docker container or as a local process.
Resource needs: The README recommends at least 8 GB of Docker memory and preferably 16 GB, especially when using machine learning.
Runtime: The documented rule of thumb for a machine-learning-enabled crawl is one minute or less per page, while crawl time varies with site complexity.
Model training: Version 2.x does not include code to train or retrain the machine-learning model; the repository points users to the v1 folder for that code.
License: The repository includes an Apache License 2.0, which grants no-charge, royalty-free rights subject to its terms.
Integrations: The README describes API calls and Docker deployment but does not name third-party integrations.
Price from: Free
