Some antivirus products are blocking retool.app

What to do

• Check whether you use Retool New app builder. Check your stack

  Paste a package.json, lockfile, Terraform or a list of domains at down.guide/stack to see every provider you depend on.

• Switch to another region or a fallback provider while it is open, if you have one.

  Otherwise back off retries and queue work, so you don't add load while it recovers.

• Watch Retool's own updates; this page re-reads them every minute.

• Subscribe to Retool's feed to hear about the next one first. RSS feed

  https://down.guide/feed?provider=retool works in Slack (/feed subscribe), Discord feed bots and any RSS reader.

Updates from Retool 3

1. investigatingNov 9, 2026, 9:30 PM UTC

   Some customers report that Norton, AVG, and other safe browsing vendors are flagging retool.app as dangerous and blocking it. Affected users may see a “dangerous webpage” warning or be unable to load published Retool apps or the app builder preview. Retool services are operating normally. We believe the block comes from how these products classify the domain. We are submitting reclassification requests to each vendor and following up with them. If your IT team manages these products, they may be able to add an exception for *.retool.app.

   We've submitted requests to have the retool.app domain properly classified on all Gen Digital products (Norton, AVG, and Avast) and are waiting for confirmation that it has been removed from the blocklist.

   We have submitted reclassification requests to the affected vendors, and warnings are clearing for some users of Norton, AVG and Avast. We are now working with the remaining security vendors and threat list providers that still flag retool.app. Because published React-based apps and the app builder preview built with the React-based app builder are served from retool.app, affected users may see those apps or the preview fail to load, often with a connection timeout and no warning page. Some VPNs, routers and company web filters can also block the domain. Apps built with the classic editor and the Retool editor itself are not affected. Retool services are operating normally. If your IT team manages these products, they may be able to add an exception for *.retool.app. We will post another update as vendors confirm.
