Identified

This issue affects Retool version 4.0.0+ (stable and edge), specifically for 1) newly-created React apps, 2) new publishes of existing React apps, and 3) cold starts of sandboxes when editing existing React apps. Existing published apps that do not get published after August 19th are unaffected. Self-hosted customers can update to 4.43.0-edge to get an immediate fix. A patch to our stable release channel is coming soon.

Identified

This issue no longer affects the React App Builder on Retool Cloud. We have identified the issue for self-hosted, and are working on releasing images with a fix

Investigating

Retool's app builder may fail to install and connect to a sandbox due to downstream dependency issues. This affects both Cloud and Self-Hosted Retool instances.

Your coding agent knows when Retool is down, and tells you when a failure is theirs, not yours. You can also get Retool incidents in a feed reader or in Slack.

Prompt
Install the outages.live MCP server, so that when something breaks you can tell if the cause is a provider we depend on and not my code. It reads the official status pages of cloud, AI, payment and developer providers and gives you their incidents as MCP tools.

Add it as a remote MCP server named "outages" at https://outages.live/mcp (Streamable HTTP, no authentication), with your CLI command or your MCP config file.

Then:
1. Make sure it connects and shows the tools get_provider, list_feed and send_feedback.
2. Call get_provider with "retool" and tell me if Retool has a problem right now.
3. From now on, when a call to a third-party service fails or becomes slow, call get_provider for that service before you change my code.

Paste this into any coding agent. It adds the server with its own MCP setup.
