Domnr vs MainWP: monitoring for every domain, not just WordPress
MainWP is a self-hosted, "not a SaaS" WordPress manager you run from your own dashboard, with no per-site fees. Domnr is a hosted domain-lifecycle tool for any domain. They solve different problems — here’s an honest comparison.
Try Domnr freeOn uptime, head to head
MainWP doesn’t monitor uptime natively — it integrates external monitors (UptimeRobot, NodePing, Better Uptime) into its dashboard. Domnr runs its own HTTP/HTTPS and TCP checks down to 30-second intervals. So on uptime, Domnr is the actual monitor; MainWP is a console that surfaces someone else’s.
Domnr vs MainWP, dimension by dimension
| Dimension | Domnr | MainWP | Edge |
|---|---|---|---|
| Primary purpose | Domain lifecycle (renewals, DNS, SSL, uptime) | Self-hosted WordPress management | Comparable |
| Pricing model | $19/mo Pro · $39 Growth · $79 Business (20% off annual); free tier | Free self-hosted core; Pro $29/mo, $199/yr, or $599 lifetime | Comparable |
| Hosting model | Hosted SaaS — nothing to run | Self-hosted on your own WordPress (you run it) | Comparable |
| Works for non-WordPress domains | Yes — any domain | No — WordPress sites only | Domnr leads |
| WordPress bulk updates & management | No | Yes — core strength | MainWP leads |
| Uptime monitoring | HTTP/HTTPS and TCP, with keyword/response assertions | Via external services (UptimeRobot, NodePing…) — not native | Domnr leads |
| Domain expiry / WHOIS tracking | Yes — WHOIS expiry, registrar lock & auto-renew (core) | No | Domnr leads |
| DNS change detection | Yes — DNS & WHOIS change detection (core) | No | Domnr leads |
| SSL certificate expiry | Yes — SSL validity & expiry on every portfolio domain | Via extensions (not a portfolio SSL view) | Domnr leads |
| Data ownership | Hosted by Domnr | Fully self-hosted — you own the data | MainWP leads |

Where MainWP wins
Self-hosted with no per-site fees
MainWP runs on your own WordPress install — you own the data and add unlimited sites without per-site charges. If self-hosting and data ownership matter, that’s a real advantage Domnr (a hosted SaaS) doesn’t match.
Deep WordPress management
MainWP does bulk updates, backups, uptime integrations, and dozens of extensions across your WP sites. Domnr doesn’t manage WordPress at all.
Where Domnr wins
One panel for the whole domain lifecycle
Domnr unifies your domain portfolio, WHOIS/expiry, DNS change tracking, SSL, and uptime in a single dashboard — not just the up/down slice.
Renewal & expiry tracking across registrars
Domnr tracks WHOIS expiry, registrar lock, and auto-renew for every domain you own, across registrars — checked as often as every 15 minutes on Growth and every 5 minutes on Business.
DNS & WHOIS change detection
Domnr snapshots DNS and WHOIS and alerts you when records, nameservers, or registrar status change — not something ping-based uptime tools do.
A 0–100 domain health score
Every portfolio domain gets a health score rolled up from SSL validity, WHOIS expiry, DNS health, registrar lock, auto-renew, and uptime — one number that tells you what needs attention.
Switching from MainWP
- Keep MainWP for WordPress management — Domnr doesn’t replace it.
- Add all your domains to Domnr’s portfolio for hosted WHOIS/expiry, registrar lock, DNS-change, and SSL tracking with nothing to self-host.
- Set up native uptime monitors in Domnr instead of wiring an external monitor into MainWP — you get sub-minute checks and incidents directly.
- Lean on Domnr’s health score for a portfolio-wide view of what needs attention, across every registrar.
Which should you choose?
If you want a self-hosted, no-per-site-fee WordPress manager and are happy running it yourself, MainWP is excellent. If you want hosted, zero-maintenance tracking of domain renewals, DNS, WHOIS, SSL, and uptime for every domain, Domnr is the fit — and the two complement each other.
