Free Plan: UptimeSignal vs UptimeRobot
Both services offer a free tier. Here's how they compare for users who don't want to pay.
UptimeRobot Free
- 50 monitors
- 5-minute check intervals
- Email alerts only
- 30-day history
- No SSL monitoring
- No keyword checks
- No status pages
UptimeSignal Free
- 25 monitors
- 5-minute check intervals
- Email alerts
- 7-day history
- Commercial use allowed
- No credit card required
- Passwordless login (magic link)
Bottom line on free plans: UptimeRobot offers more monitors on the free tier (50 vs 25), but UptimeSignal explicitly allows commercial use and requires no credit card. If you need more than 25 monitors on a free plan, UptimeRobot has the edge. But if you're running a business and want to upgrade later, UptimeSignal's $15/mo unlimited plan is much simpler than navigating UptimeRobot's tiered pricing.
Where UptimeSignal Pulls Ahead
Unlimited Monitors for a Flat Price
UptimeRobot's pricing scales with your monitor count. Their Solo plan ($7/mo) caps at 50 monitors. Need 100? That's $14/mo on the Team plan. Need 200? $21/mo on Enterprise. And if you need more, you're looking at custom pricing.
UptimeSignal takes a different approach: $15/month for unlimited monitors. Whether you're monitoring 10 endpoints or 1,000, the price stays the same. No surprise bills, no tier anxiety, no "should I remove some monitors to save money?" decisions.
Status Pages with Custom Domains
UptimeRobot offers status pages as a separate paid product. You need to pay for their PSP (Public Status Pages) add-on to get a status page for your service.
UptimeSignal includes status pages on the Pro plan at no extra cost. You get custom domain support, incident management, component grouping, and a clean design that matches your brand. No separate product, no extra billing.
Maintenance Windows (One-Time + Recurring)
Planned maintenance shouldn't trigger false alerts. UptimeSignal lets you schedule one-time and recurring maintenance windows that automatically suppress alerts during deployments, backups, or other planned downtime.
UptimeRobot offers maintenance windows on paid plans, but only basic scheduling. UptimeSignal's recurring maintenance windows are especially useful for teams with regular deployment cycles or nightly maintenance routines.
Embeddable Status Badges
Show your service status directly in your README, documentation, or website with embeddable status badges. UptimeSignal generates badges that update in real-time, so your users can see at a glance whether your service is up. This is a feature UptimeRobot doesn't offer.
Response Time SLA Alerts
Your endpoint might be "up" but responding in 8 seconds. That's effectively down for your users. UptimeSignal lets you set response time thresholds and get alerted when your API is slower than your SLA target. UptimeRobot tracks response times but doesn't alert on performance degradation.
Modern, Developer-Focused Dashboard
UptimeSignal is built with a dark-themed React dashboard designed for developers. Clean layout, fast navigation, keyboard shortcuts, and a modern UI that doesn't feel like it was built in 2012. UptimeRobot's dashboard is functional but hasn't seen a significant design refresh in years.
Where UptimeRobot Wins
To be fair, UptimeRobot has some advantages. Here's where they come out ahead.
More free monitors
UptimeRobot offers 50 free monitors vs UptimeSignal's 25. If you need lots of monitors on a free plan, UptimeRobot gives you more headroom.
Longer history retention
UptimeRobot retains up to 730 days of history on paid plans. UptimeSignal keeps 90 days on Pro. If you need years of uptime data, UptimeRobot has the edge.
Mobile apps
UptimeRobot has dedicated iOS and Android apps. UptimeSignal's dashboard is mobile-responsive but doesn't have a native app yet.
More monitor types
UptimeRobot supports ping (ICMP), port, and heartbeat monitoring in addition to HTTP. UptimeSignal focuses on HTTP(S) synthetic monitoring.
Multi-region checks
UptimeRobot checks from multiple geographic locations. UptimeSignal currently monitors from a single region (multi-region is on the roadmap).
Mature ecosystem
UptimeRobot has been around since 2010 and has a large user base, extensive documentation, and native integrations with tools like PagerDuty and OpsGenie.

Keep UptimeRobot running alongside UptimeSignal for a day or two. Verify that both services detect the same status for all your endpoints.

Configure your status page with custom domain, set up Slack/Discord/Telegram notifications, and add maintenance windows for your deploy schedule.

Frequently Asked Questions
Is UptimeSignal a good alternative to UptimeRobot?
Yes. UptimeSignal offers unlimited monitors for $15/month compared to UptimeRobot's tiered pricing that caps monitors at each level. UptimeSignal also includes status pages, SSL monitoring, keyword checks, maintenance windows, and embeddable status badges — features UptimeRobot either charges extra for or doesn't offer.
How much does UptimeRobot cost in 2026?
UptimeRobot's free plan includes 50 monitors with 5-minute intervals. Their paid plans start at $7/month (Solo) for 50 monitors with 1-minute checks, $14/month (Team) for 100 monitors, and $21/month (Enterprise) for 200 monitors. Additional monitors beyond plan limits cost extra. Compare this to UptimeSignal's flat $15/month for unlimited monitors.
Does UptimeSignal have a free plan?
Yes. UptimeSignal's free plan includes 25 monitors with 5-minute check intervals and email alerts. Commercial use is allowed on the free tier. No credit card is required to sign up, and there's no trial period - the free plan is permanent.
Is UptimeRobot's free plan still worth it in 2026?
UptimeRobot's free plan is still reasonable for personal projects and hobby sites with 50 monitors and 5-minute intervals. However, it lacks SSL monitoring, keyword checks, and advanced alert channels. If you're running anything commercial and might need to upgrade, consider whether UptimeRobot's tiered paid pricing or UptimeSignal's flat $15/month unlimited plan makes more sense for your growth.
Can I migrate from UptimeRobot to UptimeSignal easily?
Yes. Sign up for UptimeSignal (free, no credit card), add your endpoint URLs, and run both services in parallel for a day. Once confirmed, cancel your UptimeRobot plan. The whole process takes about 5 minutes per 10 monitors.
Does UptimeSignal support Slack, Discord, and Telegram alerts?
Yes. UptimeSignal Pro includes email, Slack, Discord, Telegram, and webhook alert channels. All alert channels are included in the $15/month Pro plan with no per-channel fees. UptimeRobot supports Slack and webhooks but doesn't offer native Discord integration.
What is UptimeRobot's monitor limit?
UptimeRobot's monitor limits depend on your plan: 50 monitors on Free and Solo ($7/mo), 100 on Team ($14/mo), and 200 on Enterprise ($21/mo). If you need more monitors, you need to contact them for custom pricing. UptimeSignal's Pro plan ($15/mo) has no monitor limit at all.
Does UptimeSignal offer status pages?
Yes. UptimeSignal Pro includes public status pages with custom domain support, incident management, and component grouping. You can show your service status to customers on your own domain (e.g., status.yourcompany.com). UptimeRobot charges separately for status pages through their PSP product.
What are UptimeSignal's embeddable status badges?
UptimeSignal generates embeddable status badges that you can add to your GitHub README, documentation site, or anywhere that renders HTML/Markdown. The badges show real-time uptime status (up/down) and update automatically. This is useful for open-source projects and SaaS landing pages.
Does UptimeSignal monitor SSL certificates?
Yes. UptimeSignal Pro automatically monitors your SSL certificates and alerts you before they expire. You'll get notified days in advance so you can renew before your site shows security warnings. This is included in the Pro plan at no extra cost.
Which is better for developers: UptimeSignal or UptimeRobot?
UptimeSignal is built specifically for developers and small teams. The dark-themed dashboard, passwordless magic link auth, REST API, webhook integrations, and embeddable badges are all designed with developer workflows in mind. UptimeRobot is a more general-purpose tool with a broader feature set but a less developer-focused experience.
How does UptimeRobot pricing compare to UptimeSignal for 100+ monitors?
At 100 monitors, UptimeRobot's Team plan costs $14/month while UptimeSignal costs $15/month - roughly the same. But at 200 monitors, UptimeRobot's Enterprise plan costs $21/month while UptimeSignal is still $15/month. Beyond 200 monitors, UptimeRobot requires custom pricing, while UptimeSignal stays at $15/month regardless of how many monitors you add.
