Monitoring that goes deeper than up or down.
UptimeRobot is a fine uptime checker - but if five-minute free checks, a five-integration cap and SMS that runs on one-time credit packs are getting in the way, and a failed HTTP check is all you see, it may be time for more. HostTracker has watched the web since 2004: 14 monitor types, 300+ checkpoints, voice calls that wake the right person, and status pages on every plan.
Four honest reasons
The free tier is capped where it counts
UptimeRobot's 50 free monitors come with a fixed 5-minute interval, a 5-integration cap, one status page and 3 months of data history. HostTracker's 30-day trial opens 100 monitors with every feature and no card, and the free plan stays yours afterwards.
SMS and calls are always extra
UptimeRobot's paid plans ship a one-time credit bundle that never renews - after that, every text or call is another purchase. HostTracker's paid plans include a monthly SMS allowance that tops up automatically, and voice-call alerts for the outages that must not wait for someone to open Slack.
An HTTP 200 is not the whole story
A site can answer 200 while its checkout is broken, its domain quietly expires next week, or its IP sits on a spam blacklist. Transaction checks, RDAP domain-expiry checks, SSL change detection, DNSBL and Google Web Risk monitoring catch what a plain uptime check cannot.
One flaky vantage point should not page you
Every suspected outage is re-verified from several of 300+ checkpoints before an incident opens, and the incident record names the confirming locations - fewer 3 a.m. false alarms, and evidence you can show a hosting provider.

Alerts where your team already lives
Down and Up events, repeated-failure escalations, SSL and domain warnings and blacklist verdicts - delivered to:
Plus a REST API, four official SDKs, ht-cli and an MCP server for AI assistants - see the developer platform.
Migrate in an afternoon, decide in a month
- Export from UptimeRobot. Pull your monitor list through their API - urls, names, intervals.
- Create them all in one command. Reshape into monitor JSON and run:
ht-cli monitors bulk-create --json @monitors.json - Run both for a month. The 30-day trial fits 100 monitors with every feature enabled - compare incident logs, response-time charts and alert latency on your own traffic before anything is cancelled. Keep the free plan afterwards either way.
Frequently Asked Questions
Yes. Both free plans allow commercial use today (UptimeRobot lifted its personal-use-only restriction in 2026), so the real differences sit elsewhere: UptimeRobot's free tier is capped at 5 integrations, a fixed 5-minute interval, one status page and 3 months of data, and its paid-plan SMS or voice credits arrive as a one-time bundle that never renews. HostTracker's 30-day trial opens 100 monitors with every feature and no credit card, and paid plans include a monthly SMS allowance that tops up automatically.
Export your monitors through UptimeRobot's API, reshape them into HostTracker's monitor JSON, and create them in one call with the bulk API - or one command with ht-cli: ht-cli monitors bulk-create --json @monitors.json. The 30-day trial fits 100 monitors, so most accounts can run both services in parallel for a month and compare the incident logs before deciding.
Beyond HTTP, ping, port and keyword checks, HostTracker monitors full browser transactions (log in, add to cart, pay), page speed, database queries, SNMP counters, server resources, DNS blacklists (DNSBL), Google Web Risk verdicts, domain expiration through registry RDAP data, and SSL certificate expiration and changes - 14 monitor types in total, plus 11 free instant-check tools.
Paid HostTracker plans include a free monthly SMS credit allowance that tops up automatically, and voice-call alerts ride the same credit balance - useful when a 3 a.m. outage needs to wake someone. On UptimeRobot, paid plans start with a one-time credit bundle that does not renew monthly - once it runs out, every additional SMS or call is a separate credit-pack purchase.
Email, SMS, voice calls, Slack, Microsoft Teams, PagerDuty with automatic incident resolve, Mattermost, Pushover, Pushbullet, Telegram, Discord, Viber, browser push, and signed webhooks with 15 typed events for anything custom.
300+ checkpoints across every continent. A failed check is re-verified from several other locations before an incident opens, so a single flaky vantage point does not page anyone - and the incident record shows exactly which locations confirmed the outage.
Yes, on every plan including the free one. Status pages carry components, incident history, subscriber notifications over email, Slack, Teams and webhooks, machine-readable JSON and RSS exports, and embeddable badges; Enterprise plans add white-label branding and custom domains.
The REST API v2 exposes 182 operations, documented with OpenAPI 3.1, with official SDKs for TypeScript, Python, Go and .NET, the ht-cli command-line client, a GitHub Action, and an MCP server that lets AI assistants like Claude or Cursor run checks and manage monitors; API access is included in Business, Enterprise and the 30-day trial. UptimeRobot has been building its developer surface too - an official CLI, a Terraform provider and a hosted MCP server on its API v3 - so the honest difference today is the four official SDKs, the GitHub Action and the published OpenAPI document.
