What It Is

DNS Check is a monitoring platform for managing domain portfolios. Its main focus is tracking domains, SSL, DNS, DNSSEC, HTTP/HTTPS availability, and email security from a single dashboard. It is suitable for developers, operations teams, freelancers, and agencies that want to prevent issues such as domain or certificate expiration, DNS misconfiguration, and incorrect email authentication settings from affecting clients.

Core Capabilities

Based on the provided content, its coverage is fairly comprehensive: WHOIS, SSL/TLS certificate validity and chain checks, DNSSEC validation for DNSKEY/DS/RRSIG/NSEC, SPF/DKIM/DMARC audits, HTTP/HTTPS availability and response time monitoring, and DNS propagation consistency checks via 8 public DNS resolvers. Its alerting design is also quite granular, with tiered notifications at 90, 60, 30, 15, 7, 3, and 1 day before expiration, reducing the risk of missing an issue after receiving only a single reminder. The platform also provides Health Score, Email Security Score, tags, notes, history, and renewal cost tracking, making it suitable for managing domains across multiple clients and projects.

Pricing and Deployment

Pricing follows a freemium model: the free Starter plan supports up to 10 domains; the paid Starter plan costs R$15/month or R$180/year and supports up to 50 domains; the Professional plan costs R$30/month or R$360/year, supports up to 200 domains, and includes higher-frequency HTTP monitoring plus more Webhooks. The content clearly states that Docker self-hosting is supported: after configuring an .env file on a Linux server, it can be run with docker compose up. The environment includes PHP, Nginx, and SQLite. However, whether it is open source, its license, and the repository URL are not specified.

Pros, Cons, and Who It’s For

Its strengths are that domain operations checks are centralized and its alert channels are practical. It supports Email, Slack, Discord, Telegram, and generic Webhook integrations, which can connect to Teams, PagerDuty, Zapier, n8n, and similar tools. The drawbacks are that it does not disclose SLA details, support channels, payment methods, or data retention policies, and there is no clear API/SDK documentation. It is a good fit for small and midsize teams that need lightweight, unified monitoring for domain assets. If you require enterprise-grade compliance, global SLA commitments, or complex API-based automation, further verification is needed.

Access from China

The provided content does not mention access performance from mainland China, so its status is unknown. Pricing is listed in Brazilian reais, and it is also unclear whether domestic Chinese bank cards or invoices are supported. Alternatives include UptimeRobot, Better Stack, StatusCake, Pingdom, HetrixTools, or a self-hosted Prometheus + Blackbox Exporter setup.
