How to Create Before-and-After Comparisons with OpenClaw

Document website changes with OpenClaw and ToolRouter. Visual before-and-after comparisons.

OpenClaw automates before-and-after comparison capture as a structured operation, systematically capturing matched pairs of screenshots with identical viewport settings. Output includes organized comparison pairs, machine-readable diff metadata, and timestamped archives. Feed into automated design approval workflows or stakeholder review pipelines.

1Install the CLI

npm install -g toolrouter-mcp

2Call tools directly from OpenClaw

Steps

Once connected (see setup above), use the Web Screenshot tool:

Before changes: "Capture screenshots of the pages being updated"
After changes: "Capture the same pages and compare"
OpenClaw highlights the visual differences
Use the comparisons for documentation and stakeholder communication

Example Prompt
