Detects the GSA Digital Analytics Program (DAP) script on federal websites. Badge shows DAP status at a glance; hover for details. DAP Detector is a lightweight Manifest V3 Chrome extension that instantly tells you whether the current page includes the official GSA Digital Analytics Program (DAP) Google Analytics snippet — and, when present, displays the agency, subagency, and other key parameters. Under OMB Memorandum M-23-22, every public-facing federal website must participate in DAP. This extension makes verification fast and reliable for auditors, developers, agency staff, and anyone who needs to confirm compliance.
