HTTP Observatory

Mozilla tool for scanning website security posture

About HTTP Observatory

HTTP Observatory is a Mozilla tool that scans websites and grades their use of security headers and best practices. Running your own instance means the features, storage limits, and upgrade schedule are yours to choose rather than a vendor's roadmap. Users who outgrow a hosted free tier often choose it to remove limits while keeping the same familiar workflow they already know.
