Payment Flow Degradation

3 payment-related errors in the last 60s. API latency on /api/payment/intent has increased 4x. Consider checking Stripe service status and connection pool limits.

Why are payments failing?

Based on the last 50 events, payment intent creation is timing out after 5s. The /api/payment/intent endpoint latency jumped from ~400ms to 1.8s at 12:04. This correlates with a Stripe API degradation.

What should I fix first?

Add a circuit breaker to the payment service and increase the timeout to 8s as a temporary fix. The root cause appears to be Stripe-side, check their status page.

Why Observer

Stop guessing.
Start knowing.

Every minute you spend switching between PostHog dashboards and your code is a minute you're not shipping. Observer brings it all into one place.

Never miss a live event

Events from PostHog land in your editor every 5 seconds. Watch user behavior unfold as it happens, no more tab-switching to check dashboards.

Catch issues before users report them

Every 30 seconds, AI analyzes your log stream and surfaces anomalies, error spikes, and patterns you'd otherwise miss, automatically.

Ask your logs anything

"Why did errors spike at 3pm?" Ask in plain English and get instant answers grounded in your actual data. No query language needed.

Find the needle instantly

Filter by log level, fuzzy-search across events, and select specific entries for deeper analysis. No more scrolling through noise.

Trace any issue to its root

See a suspicious insight? One click to drill down. Observer traces back to the source logs and gives you a detailed markdown analysis.

Go from log to fix in seconds

Select error logs and send them directly to Copilot or Cursor's AI agent for debugging. One button press: from seeing the problem to shipping the fix.

AI-Powered

Insights that actually matter

Observer doesn't just show you logs. It understands them. Automatic anomaly detection surfaces the signals hidden in the noise.

Loved by builders

See what teams are saying about Observer.

"The live stream is the killer feature for me. PostHog events land right in my editor every few seconds, I stopped opening the PostHog dashboard. No more tab-switching; I see what users are doing without leaving the code."

Nageswararao Telukutla Software Engineer, Dimensions

"Send to Cursor Agent is a game changer. I see an error in the logs, click one button, and Cursor starts debugging it for me. No copy-pasting, no context switching, my MTTR dropped by 60%."

Ashok Kumar Tamada Senior Software Engineer, Digitral

"Ask your logs anything, that's the feature I live in. When something breaks, I type what happened in plain English and it gives me the exact errors, timestamps, everything. By the time I hand it to the dev team, half the investigation is already done. Our bug turnaround went from days to hours because I'm not just saying 'it's broken', I'm showing them exactly what went wrong."

Harshavardhan Dasari Senior Product Manager, Digitral
