vs.
We tested Docker DMARC Reports and Open-DMARC-Analyzer for 90 days across a corporate domain, a marketing subdomain, and a parked domain. Both are free self-hosted tools, but Docker DMARC Reports felt faster to stand up for basic aggregate report viewing while Open-DMARC-Analyzer gave us more room to inspect parsed data once the pipeline was already working.

Ten dimensions, scored from 0 to 10
We scored each product against a fixed editorial rubric covering enforcement readiness, source resolution, setup, support, operations, pricing clarity, and related authentication workflows. Higher is better in every row, and a 0 means we did not find support for that capability during the test.
Docker DMARC Reports is lighter to deploy; Open-DMARC-Analyzer gives operators more analysis room
Docker DMARC Reports scored better on first setup because the Docker image, IMAP mailbox, and database path got our three domains visible quickly. Open-DMARC-Analyzer scored better on source review because Microsoft 365, Google Workspace, SendGrid, and Mailchimp were easier to compare once parsed data was in place. Both scored 0 on hosted SPF, hosted MTA-STS, blocklist monitoring, and DNS monitoring because those workflows were outside the products during our test.

Feature set
Viewer vs analyzer
Docker DMARC Reports wins on simple intake. Open-DMARC-Analyzer wins on deeper parsed review.
Docker DMARC Reports was more complete as a small ingest-and-view setup because it fetched reports from the mailbox and displayed the aggregate results. Open-DMARC-Analyzer was more useful after the parser pipeline existed, especially when we compared SendGrid and Mailchimp traffic. For buyers comparing either option with a hosted workflow, guided fixes and automated issue detection matter because raw report rows still leave sender ownership and next action work to the team.
Docker DMARC Reports
IMAP intake included
Microsoft 365 visible fast
Spoof rows easy to find
Open-DMARC-Analyzer
Better SendGrid comparison
Mailchimp drilldowns clearer
Subdomain DKIM easier
Docker DMARC Reports covered the essential aggregate report loop in our test. Microsoft 365 and Google Workspace reports arrived through the IMAP mailbox, the same-domain SPF pass and same-domain DKIM pass were visible, and the unauthorized spoof sample on the parked domain appeared as failed traffic. The weaker part was sender classification: SendGrid, Mailchimp, the support desk sender, and the unknown sender needed manual labeling outside the product.
Open-DMARC-Analyzer gave us better inspection once reports were parsed into its database. We could compare Microsoft 365 and Google Workspace alongside SendGrid and Mailchimp, then drill into disposition, SPF, DKIM, and domain-match patterns. The DKIM pass on a subdomain was easier to explain than in Docker DMARC Reports, but the product did not turn the unknown sender into an owner, fix, or policy recommendation by itself.
User experience
Speed vs control
Docker DMARC Reports felt faster on day one; Open-DMARC-Analyzer felt better once tuned.
Docker DMARC Reports had the shorter path to a working screen for our three domains, but most interpretation still happened outside the interface. Open-DMARC-Analyzer required more setup discipline, then gave us a more useful workspace for comparing senders and authentication edge cases.
Docker DMARC Reports
Fast three-domain setup
Unknown sender manual
Forwarding needed notes
Open-DMARC-Analyzer
Setup took longer
Sender review stronger
Forwarding context clearer
With Docker DMARC Reports, the primary corporate domain appeared first, followed by the marketing subdomain and parked domain after the mailbox reports accumulated. Finding the unknown sender meant scanning source rows and matching IPs against message history, not accepting a product-generated classification. The forwarded mail SPF failure was visible as an SPF fail with other context around disposition, but we had to explain the forwarding path in our own notes.
Open-DMARC-Analyzer took longer because the parser and database needed to be right before the dashboard had value. Once populated, moving between the three domains and isolating the unknown sender was more comfortable because the source-level view retained more useful fields. The forwarded SPF failure was easier to separate from a direct spoof because the DKIM and disposition context sat closer to the same review path.
Support
Self serve support
Both products depend on operator skill more than vendor handholding.
Neither product gave us a managed onboarding path, DNS handoff process, or enterprise escalation motion during the test. Docker DMARC Reports was simpler to reason about because the deployment path was smaller, while Open-DMARC-Analyzer required more confidence around parser, database, and web application maintenance.
Docker DMARC Reports
Simple support surface
DNS handoff manual
No enterprise onboarding
Open-DMARC-Analyzer
Parser support needed
Database ownership required
No paid escalation
Docker DMARC Reports support expectations matched a self-hosted project. We handled DNS rua targets, IMAP mailbox access, database setup, TLS exposure, and backup planning ourselves. For enterprise onboarding, the missing pieces were role-based access planning, change approvals, security review, and a clear escalation path when a parser or mailbox failure blocked report collection.
Open-DMARC-Analyzer also required self-directed support, with extra attention on the parser feeding the expected database schema. DNS handoff was not packaged into the product, so we wrote our own setup notes for Microsoft 365, Google Workspace, SendGrid, Mailchimp, and the support desk sender. The escalation model was public project support rather than a commercial support lane, which matters for teams with formal onboarding requirements.
Suitability
Small team vs operator team
Docker DMARC Reports suits lean internal monitoring. Open-DMARC-Analyzer suits teams that want to own the data path.
For SMBs with one or two domains, Docker DMARC Reports was easier to justify because the operational surface was smaller. For enterprises and MSPs, Open-DMARC-Analyzer had more room for custom reporting, but account separation, recurring client reporting, and alert quality still had to be built around it. Buyers running many client domains should treat MSP workflows and alert routing as core requirements, not later cleanup work.
Docker DMARC Reports
Best for one team
Weak client separation
Manual handoff notes
Open-DMARC-Analyzer
Better domain grouping
Custom reporting possible
MSP workflow manual
Docker DMARC Reports was acceptable for a single internal team reviewing the corporate domain, marketing subdomain, and parked domain in one place. Account separation was not strong enough for MSP use without surrounding access control and separate deployments. Recurring reporting and client handoff were manual exports and notes, which made it harder to hand a clear action plan to an enterprise owner after the unknown sender and forwarding cases were reviewed.
Open-DMARC-Analyzer fit a more technical operator profile. Domain grouping was more useful for comparing the three test domains, and its database-backed model gave us better options for custom reporting. It still did not behave like a managed MSP workspace: client separation, scheduled executive reports, handoff notes, and alert routing were workflows we had to design outside the product.
What each tool feels like after 90 days of real use
Docker DMARC Reports
A lean self-hosted viewer for teams comfortable owning the whole stack
After 90 days, Docker DMARC Reports felt like a useful internal utility rather than a full DMARC operations product. It gave us the basics quickly: aggregate report collection, a database, and a web viewer that made the corporate domain, marketing subdomain, and parked domain visible without buying a hosted plan.
The tradeoff showed up whenever we needed a decision, not just a report. The SPF pass with visible from mismatch, forwarded mail SPF failure, and unknown sender all required manual interpretation, and we had to maintain our own notes for sender ownership, DNS changes, and policy movement.

Open-DMARC-Analyzer
A better fit for operators who want to inspect parsed DMARC data
After 90 days, Open-DMARC-Analyzer felt more capable once we had the data path under control. The dashboard made it easier to compare Microsoft 365, Google Workspace, SendGrid, Mailchimp, and the support desk sender across the three domains, especially when we reviewed DKIM domain match and disposition changes.
The cost was setup and maintenance ownership. The product expected us to manage the parser, database, dependencies, access control, and security patching, and it did not give us guided policy movement or a packaged handoff for the unknown sender, spoof sample, or forwarding explanation.

If you cannot decide between the two, maybe the answer is Suped
Suped
Get started
Sender ownership without spreadsheet work
Docker DMARC Reports showed the unknown sender and support desk traffic, but we still had to classify owners manually. Suped's product is built to identify sending sources and turn them into owner-ready actions.
Alerts for real authentication changes
Neither self-hosted product gave us useful alert routing for the spoof sample, forwarding failure, or sudden sender changes. Suped's product focuses alerts on authentication issues that need action.
Hosted records alongside reporting
Open-DMARC-Analyzer gave us better parsed review, but hosted SPF, hosted DMARC, DNS monitoring, and hosted MTA-STS remained outside the workflow. Suped's product keeps those record-management jobs closer to the reporting evidence.
The difference was significant. We moved from limited visibility to a much clearer dashboard. Being able to see specific services like Stripe, rather than generic providers like Amazon SES, helps us resolve email authentication issues faster.
