Performance Issue – System Slowness and Lag During Edit Operations

We are experiencing significant slowness and performance degradation when working within the Retool platform. The issue became noticeable during the last hour and persists across multiple users.
Observed Behavior:

  • Very slow response times when editing components or data models.
  • General lag across the UI when navigating between screens or performing actions.
  • Occasional timeouts or freezing when saving edits.

Impact:
This is affecting productivity as users are unable to work efficiently within the platform. Edits are delayed, and in some cases, actions need to be retried.
Steps to Reproduce:

  1. Open a Retool app in edit mode.
  2. Make changes to any component or database query.
  3. Attempt to save or preview the changes.
  4. Observe the delay and performance lag.

Time of Occurrence:
Approximately since [insert time, e.g., 15:30 EEST].
Urgency:
High – this is impacting ongoing development work.
Additional Notes:
Please advise if there are any ongoing incidents or updates on your status page.

Just to say many of my apps queries have seen query timeouts (when this rarely or never happens). So seeing a similar trend as the one mentioned by @Yordan_Krushkov.

Hi @MiguelOrtiz,

Thanks for the +1! Is the issue you're seeing scoped to queries specifically or is there also a lag with UI changes? If only existing queries, is it all resources (including JS)? Could you also let me know which Retool org you're seeing this on (here or in a dm if you prefer not to share)?

I am looking into this issue internally, so I'll follow up with any updates

The one I'm seeing is only for queries (I've been getting notifications from my error tracker workflow)

Thank you! Our team is still looking into frontend performance issues.

For apps, they'd be interested to see the memory usage tab of the browser dev tools. Also curious on any overall performance patterns - is it consistently lagging, are all apps/workflows impacted, etc?
