You shipped your app. Users are signing up. Your API is handling real traffic. But how do you know if it's actually working well? If your /api/payments endpoint starts timing out at 2 AM, how long until you find out?
As an indie hacker or small team, you don't have a dedicated SRE team monitoring dashboards 24/7. You need a tool that watches your APIs and wakes you up when something breaks. Here are the 7 best options in 2026, with honest pros and cons.
What to Look for in API Monitoring
Before diving into tools, here's what matters for indie hackers:
- Free tier — you're bootstrapping, every dollar counts
- Setup speed — minutes, not hours
- Useful alerts — Slack, email, or SMS that actually reach you
- Multi-region checks — your users are global, your monitoring should be too
- Detailed metrics — not just up/down, but response time, DNS, TLS, TTFB
1. Nurbak
Best for: Developers who want detailed API metrics with minimal setup.
Nurbak is a developer-first API monitoring tool that checks your endpoints from 4 global regions (US, Brazil, France, Japan). It measures response time, DNS lookup, TLS handshake, TTFB, and response size — not just whether the endpoint is up or down.
- Free tier: 3 endpoints, 5-minute checks, 1 region, email alerts
- Pro ($29/mo): 20 endpoints, 1-minute checks, 4 regions, Slack/WhatsApp/SMS
- Setup: 5 lines in
instrumentation.ts - Unique: Encrypted credential storage (AES-256 + AWS KMS), public status pages, P95 latency tracking
Pros: Deepest metrics of any tool at this price. Multi-region from day one. WhatsApp alerts (rare). Credentials encrypted with military-grade security.
Cons: Newer product, smaller community. Free tier limited to 3 endpoints.
2. UptimeRobot
Best for: Maximum number of free monitors.
UptimeRobot is the veteran of uptime monitoring. It's been around since 2010 and has a very generous free tier.
- Free tier: 50 monitors, 5-minute intervals
- Pro ($7/mo): 50 monitors, 1-minute intervals, advanced notifications
- Setup: Add URL in dashboard
Pros: 50 free monitors is unbeatable. Simple interface. Status pages included.
Cons: Only checks from 1 region. No DNS/TLS/TTFB metrics. Basic up/down checks only. No credential encryption for authenticated endpoints.
3. Better Stack (Better Uptime)
Best for: Teams that want incident management built in.
Better Stack combines uptime monitoring with incident management, on-call scheduling, and status pages. It's a polished product with great UX.
- Free tier: 10 monitors, 3-minute checks
- Pro ($25/mo): Unlimited monitors, 30-second checks, on-call
- Setup: Quick, web-based
Pros: Beautiful UI. Incident management. On-call scheduling. Good status pages.
Cons: Gets expensive with add-ons. Focused on incident workflows more than API metrics. Less detailed performance data than specialized tools.
4. Checkly
Best for: Developers who want monitoring-as-code with Playwright.
Checkly is unique because it uses Playwright for browser checks and supports monitoring-as-code via their CLI. Perfect for teams that want their monitoring in their Git repo.
- Free tier: 5 checks, limited runs
- Pro ($30/mo): 15 checks, more locations
- Setup: CLI + config files (steeper learning curve)
Pros: Monitoring-as-code. Playwright browser checks. Multi-step API checks. Git integration.
Cons: Learning curve. Overkill if you just need API health checks. Expensive for simple monitoring.
5. Pingdom
Best for: Enterprise teams already using SolarWinds.
Pingdom has been around for 15+ years. It's reliable and well-known, now part of the SolarWinds ecosystem.
- Free tier: None
- Starts at: $15/month for 10 monitors
- Setup: Web dashboard
Pros: Reliable. Good RUM (Real User Monitoring). Enterprise reputation.
Cons: No free tier. UI feels dated. No modern alert channels (no WhatsApp, limited Slack). Per-monitor pricing.
6. Uptime.com
Best for: Teams that need SLA compliance reporting.
Uptime.com specializes in SLA tracking, compliance reporting, and multi-step API transaction monitoring.
- Free tier: None
- Starts at: $24/month
- Setup: Web dashboard
Pros: SLA compliance reports. Multi-step API transactions. Good for regulated industries.
Cons: No free tier. Expensive for indie hackers. Enterprise-focused UX.
7. Cronitor
Best for: Developers who also need cron job monitoring.
Cronitor started as a cron job monitor and expanded into uptime and health check monitoring. Good for projects that rely on background jobs.
- Free tier: 5 monitors
- Pro ($12/mo): 50 monitors
- Setup: URL-based + SDK integration
Pros: Cron job + uptime in one tool. Developer-friendly. Reasonable pricing.
Cons: Less detailed API metrics. Limited multi-region options. Smaller ecosystem.

Which One Should You Pick?
- Maximum free monitors: UptimeRobot (50 monitors)
- Deepest API metrics:Nurbak (DNS, TLS, TTFB, P95, encrypted credentials)
- Incident management: Better Stack
- Monitoring-as-code: Checkly
- Cron jobs + uptime: Cronitor
- Budget is $0: Start with UptimeRobot for quantity or Nurbak for quality
For most indie hackers building Next.js or serverless apps, Nurbak's free tier is the best starting point — you get multi-region health checks with real performance metrics, not just ping responses. When you scale, $29/month for Pro is cheaper than the cost of one undetected outage.
