Wraith is a screenshot comparison tool, created by developers at BBC News. Wraith uses a headless browser to create screenshots of webpages on different environments (or at different moments in time) and then creates a diff of the two images; the affected areas are highlighted in blue. There are two main modes for using Wraith, 'capture' mode and 'history' mode. Wraith has some built-in JavaScript and configuration file templates for you to get started with right away. If you wish to take screenshots of a component rather than the entire page, use casperjs and pass a selector along with your paths. In the 'component' example config, you can see how we specify a component name, domain path and selector we want to capture. All config options will be placed in a YAML config file. You set the headless browser, diff mode, threshold, fuzz amount and screen widths.

AInotate gives AI agents annotated screenshots. Ask an agent where a setting is and it captures the page or window, finds the elements by text or role, and draws numbered steps, Skitch-style arrows, boxes and labels placed where they cover the least content. Emails, tokens and other secrets are redacted automatically, and the agent checks a preview before it sends the image. Use it for "where do I click" answers, bug reports, how-to guides and before/after shots of a change. It runs locally as an MCP server, a CLI and an agent skill, with plugins for Claude Code, Codex, Gemini CLI and Cursor. Free and open source.
