Most monitoring tools tell you your site is down. PingRCA tells you why— in plain English, in seconds.
The incident response nightmare
Your pager fires. Pingdom says DOWN. That's all you get. You roll out of bed, open your laptop, and start the ritual: SSH into the server, check if the process is running, tail the application logs, stare at stack traces you barely recognize in your half-asleep state.
Then the second-guessing starts. Is it DNS? Did the SSL certificate silently expire? Did a CDN config get pushed that broke routing? Did the last deploy introduce a crash? Each hypothesis takes five minutes to check. And meanwhile, your site is still down. Every minute you spend debugging is a minute your users are hitting error pages.
For an experienced SRE on a large team, that diagnostic loop takes 20–40 minutes. For a solo founder or a small team without a dedicated on-call rotation, it can take longer — if anyone's even awake to respond at all. Most small teams find out about downtime from their users, not their monitoring tools. That's not a monitoring problem. It's a diagnosis problem.
The alert isn't the bottleneck. Every tool in this space sends an alert. The bottleneck is what happens after: the 30 minutes of manual investigation that stands between “something is wrong” and “here's what to do about it.” PingRCA was built to eliminate that gap.
The same check interval as every other tool. Completely different depth of analysis.
Every check probes DNS resolution, SSL validity and expiry, redirect chains, HTTP headers, and response body — not just HTTP status.
When your site goes down, our AI analyzes all probe data and writes a specific, actionable diagnosis: “SSL certificate expired 2 days ago. Renew with: certbot renew.”
If your site flickers up-down-up, PingRCA doesn't spam you with 10 incident notifications. It tracks the flap count and surfaces one coherent timeline.
Three real-world failure scenarios and the diagnosis PingRCA delivers automatically.
Monitor: api.acme.com
Status: DOWN
AI Diagnosis
SSL certificate expired 3 days ago (Let's Encrypt). DNS resolves correctly. Server is reachable but refusing HTTPS connections. Run: certbot renew --nginx
Monitor: app.startup.io
Status: DOWN
AI Diagnosis
DNS lookup failed. NXDOMAIN returned for app.startup.io — this usually means a missing or incorrect DNS record. Check your domain's A/CNAME records in your DNS provider dashboard.
Monitor: api.myapp.com
Status: DOWN
AI Diagnosis
DNS resolves, SSL valid, TCP port 443 open — but server is returning HTTP 503. This is an application-level failure, not infrastructure. Check your app logs for recent crashes or deployment issues.
These aren't hypotheticals. These are the failure modes PingRCA was built to diagnose automatically.
We're priced for the teams that need this most — solo founders, small engineering teams, bootstrapped startups.
3 monitors, 5-minute checks, basic AI analysis. No credit card, no trial timer, no expiration. Get started and stay if 3 monitors is all you need.
Less than a dinner out. Covers 20 services with 1-minute check intervals, 30 AI diagnoses per month, and API access. For freelancers and small teams who are serious about staying online.
About a tenth of a single Datadog seat. Covers 100 services with 30-second checks, unlimited AI diagnoses, incident history, and priority support. For agencies and growing teams.
We don't charge extra for SSL monitoring, API access, or Slack integrations. Everything you need to run a serious on-call workflow is included at every paid tier.
PingRCA is built with FastAPI, async Python, and Next.js. The monitoring backend runs fully async checks in parallel across all your monitors, so high check frequency doesn't mean high latency. The API is fully accessible via X-API-Key auth — you can integrate alerting into your own tools, pipe incident data into your internal dashboards, or trigger checks from your CI/CD pipeline.
There are no agents to install, no SDK to learn, no YAML config to write. You enter a URL, pick a check interval, and you're monitored. The complexity lives in our diagnostic layer, not in your setup process.
