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

13,005reachable checks. The line plots the median of each interval, so one timeout can't spike it, and we lead with the median rather than an average, which a single slow response would skew. Failed checks are excluded: a timeout is not a response time.
Responding normally (~82 ms typical).
Uptime & history
Tracking since Jun 22, 2026% of our checks that found LangSmith 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.

Recent incidents
No recent incidents reported on LangSmith's official status page. Historical incident tracking begins once our database is live — for now, see the official status page.
What this page can and can't tell you
- How we decide. We combine LangChain'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 LangChain'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 LangSmith API can fail while the app is fine. The capability panel breaks it down.
- Green doesn't mean everyone. If our check reaches LangSmithbut you can't, the problem is more likely local: your network, a VPN, browser extensions, or cache.
Frequently asked
Is LangSmith down right now?+
Right now, LangSmith appears to be operational. LangSmith looks healthy. The official status page reports all systems operational and our independent checks are passing.
Is there a LangSmith down detector?+
Yes — this page is a live LangSmith down detector. It combines LangSmith'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. LangSmith is currently operational. We only show signals we can actually verify — never invented report totals.
Is there a LangSmith outage today?+
No active LangSmith outage is detected right now — it appears operational. For past incidents and dated outage recaps, see LangSmith's status history below.
What is LangSmith's server status and API status right now?+
LangSmith is currently operational. Server status and API status aren't always the same — the LangSmith 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 LangSmith API down? (LangChain API status)+
Check the API row in the capability panel above — LangSmith is currently operational overall, but the API can carry its own status. For developers, "LangChain API status" problems usually surface here first, because we read LangChain's own status feed and watch the API surface directly.
Why is LangSmith slow or not working?+
Common causes are an upstream provider incident, API rate limits during peak demand, a regional CDN issue, or maintenance. LangSmith 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 LangSmith down for everyone or just me?+
We check LangSmith from our own servers, independent of your device or network, and combine that with LangChain's official feed and user reports. If our independent check reaches LangSmith 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, LangSmith is down for everyone.
How can I tell if it's LangSmith or my own connection?+
AIDownCheck runs an independent reachability check from our own servers, separate from LangSmith'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 LangSmith's side.
What can I use while LangSmith is down?+
Good alternatives include Pinecone, Groq. We track their live status too, so you can switch to one that's currently operational.
Where is LangSmith's official status page?+
LangSmith's official status page is at https://status.smith.langchain.com. AIDownCheck reads it automatically and combines it with our own checks — so you get the answer without juggling tabs.
