SolidPing

SolidPing is an open-source uptime and infrastructure monitoring platform offered in hosted and self-hosted forms. It suits teams that need extensive check coverage, serious on-call routing, and status pages rather than a simple website ping. The main trade-off is that hosted plans exclude SMS and voice alerts, while self-hosting leaves those channels to your own provider setup.

Overview

SolidPing supports 40 check types, including HTTP, TCP, DNS, databases, email servers, Docker, Kubernetes, headless-browser checks, and custom JavaScript. Checks can run every 10 seconds and use six monitoring locations, giving teams a way to watch application dependencies and infrastructure as well as public sites. A stated limit of 1,000 monitors applies to the product generally, while paid hosted tiers raise that allowance further.

The hosted service stores account, monitoring, incident, and backup data in France on OVHcloud. SolidPing states that it uses TLS 1.2 or newer in transit, encryption at rest, application-layer encryption for selected credentials, and Argon2id password hashing. It does not hold ISO 27001 or SOC 2 certification, so organizations requiring either certification should look elsewhere.

Key features

Monitoring and alerting

SSL-expiry alerts and server monitoring cover common operational blind spots. Notifications can reach Slack, Discord, Microsoft Teams, Google Chat, Mattermost, Matrix, Zulip, Telegram, email, webhooks, PagerDuty, ntfy, Gotify, Pushover, and Web Push. Twilio SMS and voice are supported for self-hosted installations, but hosted plans do not include SMS, voice, or WhatsApp delivery. That distinction is important for teams whose escalation policy depends on telephone networks.

On-call and status pages

Rotation schedules, overrides, iCal feeds, and multi-step escalation policies are included even on Free, making the product unusually capable for small teams that need structured ownership without paying first. Public status pages support sections, subscribers, incident updates, and per-check uptime and response-time metrics. Custom domains are plan-metered, so branded pages become a paid consideration.

Deployment and integration

The self-hosted edition is a single Go binary using SQLite or PostgreSQL and is released under AGPL-3.0. Hosted users get a REST API, an MCP endpoint, and sign-in through Slack, Discord, Google, GitHub, GitLab, Microsoft, OIDC, or LDAP. Self-hosting provides the broadest quotas, but it also makes infrastructure, updates, and alert-provider credentials your responsibility.

Pricing

Free costs 0.00 EUR forever and includes five team members, 10 check executions per minute, 100 monitors, one private-location agent, and on-call features. It has no custom status-page domain and places a SolidPing badge on status pages. This is a strong starting point for a small service, but the execution rate and monitor cap constrain larger estates.

Starter costs €5 a month, billed monthly with VAT excluded. It raises capacity to 10 team members, 20 executions per minute, 1,000 monitors, and two private-location agents, with one custom domain and white labeling. It fits a growing team that needs branded status communication without a large monitoring footprint.

Pro is €15 a month, billed monthly excluding VAT, with 50 team members, 100 executions per minute, 2,000 monitors, three private-location agents, and three custom domains. Scale costs €45 a month, billed monthly excluding VAT, and expands those figures to 250 members, 500 executions per minute, 5,000 monitors, five agents, and 10 custom domains. These tiers suit organizations that need higher check throughput and multiple branded pages.

Self-hosted is free forever, with unlimited monitors, check rate, private-location agents, and status-page domains, plus 30 members by default. It is the value leader for teams able to operate their own deployment; hosted plans trade those unlimited quotas for managed service convenience.

Platforms

SolidPing is available through its web interface and API, with Linux and Windows support plus self-hosted deployment. The Go-binary architecture and SQLite or PostgreSQL options make it practical for controlled infrastructure environments.

Who it's for

Choose SolidPing for infrastructure and platform teams that need varied protocol checks, fast intervals, private monitoring agents, escalation policies, and public status pages in one system. The Free plan also suits small teams that want on-call scheduling without a subscription. It is less suitable for organizations that require ISO 27001 or SOC 2, or for hosted users who need built-in SMS and voice escalation.

Pros and cons

• Pros: 40 check types cover applications, infrastructure, containers, databases, and browser workflows.
• Pros: On-call rotations, overrides, calendars, and escalations are included on every plan, including Free.
• Pros: Self-hosting offers unlimited monitors, check rate, agents, and status-page domains at no license cost.
• Cons: Hosted plans exclude SMS, voice, and WhatsApp alerts, limiting phone-based escalation unless you self-host.
• Cons: Free and low-tier hosted execution limits can become restrictive as monitor counts and check frequency grow.
• Cons: No ISO 27001 or SOC 2 certification may block regulated procurement.

Alternatives

For a smaller hosted footprint, Dotcom-Monitor offers a free tier with 25 targets, five-minute checks, and two locations. HetrixTools is a better fit when 15 uptime monitors, 15 server monitors, one-minute checks, and four locations cover your needs.

openstatus suits teams wanting a free hobby tier with one monitor and one status page, while Better Uptime targets personal projects with 10 monitors and heartbeats plus Slack and email alerts. Choose Checkmate for a free, self-hosted product with unlimited monitors and 12 alert channels.

Spectate is an alternative for mobile-oriented monitoring. Statping-ng is a free open-source self-hosted option. StatusBot is worth considering when project-based status management is the priority.

Verdict

SolidPing is a strong choice for teams that want broad monitoring, built-in on-call operations, and flexible hosted or self-hosted deployment. Pick it for its unusually generous Free on-call feature set and unlimited self-hosted model; look elsewhere if certification requirements or hosted phone alerts are non-negotiable.
