dmarcian alternative: open source & self-hosted
A self-hosted, open-source dmarcian alternative with no per-domain pricing — the same DMARC visibility, but your report data stays on your own infrastructure.
dmarcian helped create this category — it was co-founded by one of DMARC’s original architects — and it’s a capable, well-supported hosted platform, with a free tier for personal use and paid plans above it. It is vendor-hosted, priced by domains and message volume, and your report data lives in dmarcian’s cloud. DMARC Analyzer is open source and self-hosted: unlimited domains at no per-domain cost, with reports that never leave your infrastructure.

Where dmarcian fits
If you want a fully managed service with vendor support and don’t need to self-host, dmarcian is a mature, credible option.
Where DMARC Analyzer fits
If you care about data sovereignty, want no per-domain cost at scale, or value open source you can audit and run yourself, DMARC Analyzer is built for exactly that. New to DMARC? Start by publishing your first record and reading the reports.
Worth being plain about the overlap: dmarcian’s free tier covers personal use on up to two domains, and you get a vendor-run dashboard with none of the setup this project asks of you. If that fits — a couple of personal domains, no need to self-host — it’s a perfectly reasonable place to stop looking. Where DMARC Analyzer earns its keep is past that: more domains, client work, or data that has to stay on infrastructure you control.
