Langfuse Status FAQ

Is Langfuse down right now?

The verdict at the top of this page comes from the latest poll of the official Langfuse status feed and refreshes automatically, so you are not looking at a stale cached answer. PulsAPI re-checks it every 60 seconds.

What should I do if Langfuse is not working?

Check the component list on this page first to see if your failure matches a known outage. If it does, you can report the issue for other engineers, follow the incident timeline for vendor updates, and run any fallback your app supports until Langfuse recovers.

How do I check Langfuse uptime history?

PulsAPI tracks Langfuse uptime over 30, 60, and 90-day rolling windows. The current 30-day uptime is 100.00%. The 90-day uptime strip on this page is public: no account needed. A free account adds alerts whenever Langfuse changes state, plus 15 days of incident detail; Pro extends that to 90 days and Business to 13 months.

How fast does PulsAPI detect Langfuse outages?

PulsAPI reads the official Langfuse status page. PulsAPI re-checks it every 60 seconds. Alerts reach Slack, Discord, Microsoft Teams, PagerDuty, or email once a change has held for 5 minutes, so a one-minute blip does not page you.

Does PulsAPI track individual Langfuse components?

Yes. PulsAPI monitors 5 individual Langfuse components, so you can see which service or region is affected instead of a generic "service degraded" banner.

Can I get alerts when Langfuse goes down?

Yes. Create a free account and subscribe to Langfuse: the free plan covers three services with unlimited email alerts and no monthly notification cap. Paid plans lift the monitor limit entirely (Pro and above do not meter how many vendors you watch) and route the same alerts into Slack, Discord, Microsoft Teams, PagerDuty and webhooks.

How do I report an issue with Langfuse to the community?

Click "Report an issue" at the top of this page, pick the issue type and severity, and optionally add your region and a short note. Reports are anonymous and help other engineers spot Langfuse problems early. Official status pages often lag real incidents by 10 to 20 minutes.

Is there a free way to monitor Langfuse?

Yes. The free plan covers 3 monitored services with unlimited email alerts, permanently, so Langfuse plus two more costs nothing. Every new account also opens with a 30-day Business trial (unlimited monitors, Slack alerts, SLA reporting) with no credit card.

Track Langfuse with the rest of your stack

2660+ vendors in one dashboard, and an email the moment any of them changes state. Three free, and no monitor limit at all from $29/mo, unlike the alternatives, which keep charging by the monitor.
