DiffiCat is a browser-based website migration testing and visual regression tool. It compares a source site (Site A) against a target site (Site B) page by page across three checks: page existence (HTTP status, broken pages and redirects), content accuracy (text and SEO changes) and pixel-level visual regression at widths from 320 to 2560px, with ZIP exports of text/CSV reports and screenshots. A free trial runs in the browser at app.difficat.com with no install or card. DiffiCat also offers an Agent API for AI agents over REST or MCP, with a free allowance needing no key and paid use via prepaid keys, Pro accounts or USDC on Base (x402).
