PowerDMARC alternative: self-hosted for agencies
A self-hosted, open-source PowerDMARC alternative for agencies and MSPs — multi-tenant DMARC monitoring with unlimited domains and no per-domain fees.
PowerDMARC is a full-featured commercial platform with a strong MSP and white-label program, sold primarily as SaaS and priced by domains and message volume. DMARC Analyzer gives agencies and MSPs the same multi-client model — but open source, with unlimited domains at no cost and client data on infrastructure you control.

Where PowerDMARC fits
If you want a managed, white-label platform with vendor support and don’t need to self-host, PowerDMARC has a well-developed MSP offering.
Where DMARC Analyzer fits
If you’re an agency or MSP that would rather self-host, own client data outright, and skip per-domain billing, DMARC Analyzer is built around exactly that multi-tenant, self-hosted model. See the per-provider setup guides for onboarding client domains, and a guide to running DMARC across many client domains.
Worth being plain about the trade: PowerDMARC bundles BIMI, MTA-STS and TLS-RPT management alongside DMARC, and handles forensic (RUF) reports — ground this project doesn’t cover. If you want one vendor and one bill for the full protocol stack, and you’re comfortable paying for that convenience, that’s a real reason to pick them over stitching the pieces together yourself.
