Sentinel is website monitoring for agencies, freelancers and DevOps teams that are responsible for other people's uptime. It checks websites, APIs, SSL certificates, DNS, domain expiry, ports and cron jobs from four regions on three continents, and only opens an incident when the regions agree, so a blip at one vantage point never becomes a false alert. Alerts go where the team already works: email, SMS, Slack, Discord, Microsoft Teams, PagerDuty and signed webhooks, with routing per monitor and per severity and quiet hours. Every client gets a branded status page, uptime reports can be scheduled to an accounting or client inbox, and deploys from GitHub are drawn on the uptime charts beside the incidents that follow them. Monitoring can be managed as code through the API, a CLI and a Terraform provider, and from an AI assistant over MCP: ask what is down, triage an incident or add a monitor in conversation. The free plan covers 10 monitors with SSL, DNS and API checks included and no card required. Paid plans start at $14 a month.

VitalSentinel is all-in-one website monitoring for the overlap between technical SEO and web performance – the two sides of a site usually watched by different tools, different teams, and different budgets. Uptime, Core Web Vitals, search visibility, and traffic all report into one dashboard, and you hear about a problem in minutes rather than days. Most sites break quietly. Pages drop out of Google. Load times creep up after a deploy. A robots.txt change blocks crawling. The site goes down overnight. What each of those costs you is a function of how long it goes unnoticed, and VitalSentinel exists to shorten that window. Ten modules, all included on every plan. MONITORING • RUM Monitoring – Core Web Vitals from real users at the 75th percentile: LCP, INP, CLS, FCP, and TTFB, segmented by device, browser, and location. • CrUX Monitoring – Chrome User Experience Report field data, the dataset Google uses to assess page experience. • Synthetic Monitoring – scheduled Lighthouse audits for repeatable, comparable performance scores, with additional test locations on higher plans. • Uptime Monitoring – 24/7 availability and response-time checks, plus SSL certificate and domain expiry warnings. • Robots.txt Monitoring – change detection and validation for crawl directives. • Indexing Monitoring – tracks how many of your pages Google has indexed and flags de-indexing. AUDITS • Inspector – an on-demand technical SEO and performance audit of any public URL. It runs 130+ rules across six parallel data sources and returns a single 0-100 score, weighted across five pillars: Performance, SEO, Security, Infrastructure, and Availability. You get per-pillar scoring, charts and request waterfalls, raw data from every check, and a severity-ranked fix list written for engineers. No tracking script and no domain verification required, so it works on any URL including staging and competitor pages. ANALYTICS • Web Analytics – cookie-free, privacy-first traffic and e-commerce analytics that need no consent banner. The script is roughly 13KB gzipped, about four times smaller than Google Analytics. • Google Search Console – clicks, impressions, CTR, and average position in one view, with alerts when search visibility drops significantly. • Google Analytics – your key Google Analytics 4 metrics in a simplified dashboard. ALERTS Every monitor feeds one alert stream instead of five separate inboxes. Alerts arrive by email and in-app within 60 seconds of detection, and a recovery notification follows the moment an issue resolves. Uptime checks run as often as every 60 seconds on the top plan. SETUP Self-serve, and live the same day. Paste one asynchronous script tag that never blocks rendering, then connect Google Analytics and Google Search Console with one-click OAuth. Monitors go live immediately and your first alert can land within minutes. The script is framework and CMS agnostic. PRICING Public, flat, monthly pricing from a permanently free plan up to 50 domains. Every plan ships all ten modules – the plan you pick sets your limits (domains, data volume, check frequency, history retention), never your feature list. Nothing is locked behind a higher tier. WHO IT IS FOR Technical SEO specialists who need indexing and robots.txt regressions caught the day they happen. Developers and engineering leads who need real-user performance regressions caught within minutes of a deploy. Agencies running every client site from one dashboard. In-house marketing and web teams held to traffic and revenue numbers. Start on the Free plan: one domain, every module, no credit card and no trial clock.

What is Xitoring? Xitoring is an all-in-one monitoring platform for servers, websites, and status pages, with AIOps built in. It replaces the typical stack of separate tools — an uptime checker, a server monitoring agent, and a status page service — with one dashboard, one lightweight agent, and one flat, predictable price. Teams use Xitoring to know about problems before their customers do: a website going down, a disk filling up, an SSL certificate expiring, a cron job silently failing, or a database running out of memory. When something breaks, the right person is alerted within one minute through the channel they actually answer. Who is Xitoring for? Xitoring is built for DevOps teams, system administrators, managed service providers (MSPs), hosting companies, SaaS businesses, and growing SMBs that self-manage Linux or Windows infrastructure. It delivers the feature depth teams expect from enterprise monitoring suites, at a price point and setup effort that fits teams of one to five hundred. MSPs can manage monitoring for multiple clients from a single account with team access and role-based permissions. Setup: one command, no configuration files Install the Xitogent agent with a single command — curl on Linux, MSI on Windows — and it immediately auto-discovers what is running on the server and starts monitoring it. More than 30 services are detected and configured automatically, including Nginx, Apache, IIS, PHP-FPM, MySQL, MariaDB, PostgreSQL, MongoDB, Redis, KeyDB, Docker (hosts and containers), RabbitMQ, Kafka, HAProxy, Varnish, Supervisor, and CouchDB. Supported platforms: Ubuntu, Debian, CentOS, RHEL, Rocky Linux, Amazon Linux, and Windows Server 2016 and later. Uptime monitoring Uptime checks run at 1-minute intervals from more than 15 global probing nodes. Every outage is verified from multiple locations before an alert fires, eliminating the false positives that plague single-location checkers — you get paged for real incidents, not routing hiccups. Check types: HTTP and HTTPS with keyword, status-code, and response validation; Ping (ICMP); DNS; API; Mail (SMTP, IMAP, POP3); FTP; TCP; UDP; Heartbeat; and Cron job monitoring. Heartbeat and cron checks catch the failures nothing else catches: backup scripts that stopped running, queue workers that died quietly, scheduled tasks that never fired. SSL certificate and domain expiry monitoring are included, with advance warnings before expiration — preventing the most avoidable outages of all. Server monitoring The Xitogent agent collects metrics at 1-minute resolution: CPU per core, load averages, memory, swap and page file, disk usage and I/O, IOPS, network traffic per adapter, and the state of processes and services. Historical data and trends support capacity planning and post-incident analysis. Docker monitoring covers both hosts and individual containers, with per-container CPU, memory, network, and state — so you can tell instantly whether a problem lives in a container or the underlying server. Alerting: 20+ notification channels Alerts route through more than 20 channels: Email, SMS, Phone Call, Mobile Push, WhatsApp, Telegram, Slack, Microsoft Teams, Discord, Google Chat, Mattermost, PagerDuty, Opsgenie, Splunk On-Call, Spike.sh, Ntfy, Gotify, Pushover, Pushbullet, Webhooks, and Zapier. Notification roles let you route different servers and checks to different people and teams, so the database alert reaches the DBA and the website alert reaches the web team. AIOps: monitoring you can talk to Xitoring includes a built-in AI assistant that is wired directly into your metrics, charts, and incidents. Ask plain-English questions — "which servers are running hot on memory this quarter?", "what likely caused last night's alert?", "compare disk growth across my web servers" — and get ranked, specific answers grounded in your actual data, not generic troubleshooting advice. Through the Xitoring MCP server (Model Context Protocol), AI assistants and agents such as Claude and Cursor connect directly to your monitoring: reading metrics, inspecting incidents, acknowledging alerts, and creating or modifying monitors. Your team's AI tooling gets the same access as the web panel. Xitoring is one of the few monitoring platforms at any price point that works natively with AI agents. Status pages and incident management Publish public or private status pages, hosted on your own domain and fully white-labeled with your branding, colors, and logo. Component status updates automatically from real check results — no one has to remember to post an update during an outage. Announce scheduled maintenance in advance, post incident updates from detection to resolution, and reduce support ticket volume when things go wrong. Incident management is built in, with root-cause context attached to every incident: which check failed, from which locations, what changed on the server, and which services were affected. SLA reporting documents your availability commitments. Apps, API, and integrations Native iOS and Android apps keep on-call engineers covered anywhere, with push notifications and full incident visibility. A complete REST API supports automation and custom integrations. A browser extension for Chrome and Edge puts monitoring status one click away. Pricing: flat, public, predictable Xitoring pricing is flat and published — no per-metric billing, no per-check surprises, no usage-based fees that spike after a busy month, and no "contact sales" wall. The free forever plan includes 2 servers and 8 uptime checks, with no credit card required. Paid plans start at $4.99 per month, and every paid plan comes with a 30-day free trial. Why teams switch to Xitoring Teams typically arrive at Xitoring from one of three places: outgrowing a basic uptime checker that can't see inside their servers; consolidating multiple single-purpose subscriptions into one platform; or leaving an enterprise observability suite whose usage-based bill became unpredictable. Xitoring's answer to all three is the same — full-stack server, uptime, and status page monitoring, deployed in minutes, with AI built in and a price you can predict.
