Is Langfuse down?
Langfuse looks healthy. The official status page reports all systems operational and our independent checks are passing.
Langfusedown detector & server status
Is Langfuse down or not working right now? This live Langfuse down detector combines Langfuse's official status feed, our own independent checks, and first-party user reports — and shows whether it's the LangfuseAPI, the app, or a specific capability that's affected, plus the upstream AI provider it depends on. Use it to tell whether Langfuseis having an outage today, and whether it's down for everyone or just you.
Crowd signal — your reports, not our automated checks.

Uptime & history
Tracking since Jun 22, 2026% of our checks that found Langfuse fully operational — a degraded check counts against it, because a slow or partly-broken service is not a working one. Down and degraded time are counted at our 5-minute check resolution, so both are approximate. Longer windows fill in as data accrues — we never show uptime we haven't measured.

What this page can and can't tell you
- How we decide. We combine Langfuse's official status feed, our own independent check from US East (Virginia), and first-party reports from readers. The confidence badge shows how many of those signals agree.
- On root cause. We have no visibility inside Langfuse's systems. We report what the signals show rather than guessing at an internal cause.
- Outages are rarely all-or-nothing. Some are regional. Some hit one surface while the rest works, so the Langfuse API can fail while the app is fine. The capability panel breaks it down.
- Green doesn't mean everyone. If our check reaches Langfusebut you can't, the problem is more likely local: your network, a VPN, browser extensions, or cache.
Frequently asked
Is Langfuse down right now?+
Right now, Langfuse appears to be operational. Langfuse looks healthy. The official status page reports all systems operational and our independent checks are passing.
Is there a Langfuse down detector?+
Yes — this page is a live Langfuse down detector. It combines Langfuse's official status feed, our own independent reachability check, first-party user reports, and the AI dependency graph, then shows a confidence level so you can tell a real outage from a local glitch. Langfuse is currently operational. We only show signals we can actually verify — never invented report totals.
Is there a Langfuse outage today?+
No active Langfuse outage is detected right now — it appears operational. For past incidents and dated outage recaps, see Langfuse's status history below.
What is Langfuse's server status and API status right now?+
Langfuse is currently operational. Server status and API status aren't always the same — the Langfuse API can fail while the web app works, or vice-versa. The capability panel on this page breaks status down by surface (API, app, and any image/voice features) so you can see exactly which part is affected.
Is the Langfuse API down? (Langfuse API status)+
Check the API row in the capability panel above — Langfuse is currently operational overall, but the API can carry its own status. For developers, "Langfuse API status" problems usually surface here first, because we read Langfuse's own status feed and watch the API surface directly.
Why is Langfuse slow or not working?+
Common causes are an upstream provider incident, API rate limits during peak demand, a regional CDN issue, or maintenance. Langfuse is currently operational. We show the official status, our independent check, and a confidence level so you can see which signals point to a real problem.
Is Langfuse down for everyone or just me?+
We check Langfuse from our own servers, independent of your device or network, and combine that with Langfuse's official feed and user reports. If our independent check reaches Langfuse but you can't, the problem is most likely local — try a different network, disable a VPN/extensions, or clear your cache. If our check and the official status both show problems, Langfuse is down for everyone.
How can I tell if it's Langfuse or my own connection?+
AIDownCheck runs an independent reachability check from our own servers, separate from Langfuse's official status page. If our check passes but you still can't connect, the problem is more likely local — try a different network, clear your cookies, disable VPN/extensions, or use a different browser. If our check is failing too, it's more likely Langfuse's side.
What can I use while Langfuse is down?+
Good alternatives include LangSmith, Weights & Biases. We track their live status too, so you can switch to one that's currently operational.
Where is Langfuse's official status page?+
Langfuse's official status page is at https://status.langfuse.com. AIDownCheck reads it automatically and combines it with our own checks — so you get the answer without juggling tabs.
