Is Tabnine Down? How to Check Tabnine Status in 2026

Tabnine sits quietly inside your editor and finishes your code before you finish typing it — until it doesn't. Because AI completion is passive, an outage rarely throws a loud error. Instead the suggestions just stop appearing, and you're left wondering whether Tabnine is down or whether something broke on your machine.

Whether you're seeing a connection error in the Tabnine panel, a spinning "loading" indicator that never resolves, or simply silence where autocomplete used to be, this guide helps you answer: is Tabnine down, or is it just you?

How to Check if Tabnine is Down (Fastest Methods)

1. Check the Official Tabnine Status Page

Tabnine publishes a live status page at status.tabnine.com. It reports uptime for the cloud completion model, authentication, and the web dashboard. If there is a known incident, it will appear here first.

2. Reload Your IDE and Confirm You're Signed In

Roughly half of "Tabnine is down" reports are actually expired sessions or a stalled extension. In VS Code run Developer: Reload Window; in a JetBrains IDE, invalidate caches and restart. Then check the Tabnine status bar item — if it says you're logged out, re-authenticate before assuming an outage.

3. Search X (Twitter) and DownDetector for Real-Time Reports

Search "Tabnine down" or "Tabnine not working" filtered by Latest, and cross-check DownDetector. A cluster of reports in the last hour is a strong signal the outage is on Tabnine's side, not yours.

4. Use API Status Check for Automated Monitoring

For teams that standardize on Tabnine, API Status Check monitors the service and sends instant alerts via Slack, email, or PagerDuty — so a silent completion outage doesn't quietly drag down everyone's productivity.

Why Does Tabnine Go Down?

Tabnine's hybrid local-plus-cloud architecture creates a few distinct failure modes:

• Cloud Model Unreachable: Tabnine's larger models run in the cloud. If that inference service or its API gateway is overloaded or down, completions stop even though the extension is installed correctly.
• Expired Authentication: Session tokens expire on a schedule. When they do, the extension silently disconnects and shows no suggestions — indistinguishable from an outage until you re-check your login.
• Local Engine Crash: Tabnine runs a background engine process for local completions. If it crashes or is killed by the OS under memory pressure, suggestions vanish until the IDE restarts it.
• Corporate Firewall / Proxy: Networks that block or throttle Tabnine's endpoints will look exactly like a Tabnine outage. This is common on VPNs and locked-down enterprise networks.
• Self-Hosted Server Issues: Enterprise customers running Tabnine on-prem depend on their own model and license servers — if either is unavailable, completions fail regardless of Tabnine's cloud status.

Tabnine Troubleshooting Checklist

Building a Resilient AI Coding Setup

AI code completion is now core to how many developers work, so it's worth having a backup you can flip on in seconds rather than losing an afternoon to an outage:

Keeping a second assistant installed (but disabled) means a Tabnine outage costs you a two-second toggle instead of a broken flow.

Tabnine Outage History & Uptime

Tabnine historically maintains strong uptime for its completion service, and most reported problems trace back to authentication, IDE extension, or local network issues rather than full outages. When genuine incidents do occur, they typically resolve within 30–90 minutes and are posted to status.tabnine.com.

Conclusion: Don't Let a Silent Outage Slow You Down

The tricky thing about Tabnine outages is how quiet they are — no crash, no popup, just missing suggestions. The developers who lose the least time are the ones who can tell in ten seconds whether it's Tabnine or their own setup, and who have a fallback ready.
