👋 Flagging that the CSV import logic for saved groups seems like it doesn't make sense It's collapsing all the values onto one line, then splitting by

,

But a CSV of e.g. user IDs would normally look like this:

user_id
a
b
c

This then turns into a single row in the group -

user_idabc

😂 So it should probably at least be putting a comma at the end of each line before removing the linebreaks?

on the sql template doc, probably it should have been

(e.g. use '{{ startDate }}' instead of {{ startDate }}).

instead of the original

(e.g. use {{ 'startDate' }} instead of {{ startDate }}).

?

Would be nice to have a better layout for the Attributes that makes the description easier to read (by giving it more space). IMHO the Data Type column can be much smaller 😄

Hi! 👋 My company is planning to use GrowthBook, but as part of the security vendor assessment aligned with ISO27001 requirements, we need some additional information. Could you help us with responding to the request from our security team, sent on January 17, 2025? The request was sent through Trustcenter using the email *zorg***man@macpaw.com*, but unfortunately, we haven’t received a response yet. If you’d prefer the request to be resent through a different communication channel, please let me know! Thank you!

Hi @Growthbook Team, I cannot access my Growthbook website; it always shows "This site can't be reached."

Hey Growthbook Team! Thank you for the great product. I would like to write a feature request. Our team daily check A/B tests in Growthbook. We have 3 pages of tests. And If I check AB test on the 2nd or 3rd page and want to go check the next test I need to come back to previous page in browser (it is always the first page of AB tests) then choose the 2nd or 3rd page, then find the next test and open it. I do it daily many times. It will make my work much easier if on the current page of AB test would be a button "Next test". This is my idea. Maybe you know how to solve this navigation issue better. Thanks in advance.

Am I right in thinking that once a visual editor test has been archived you can no longer look up what the CSS and JS changes that were applied were? I'd be quite useful to be able to look back as a reference

Hi team, is there any chance https://github.com/growthbook/growthbook-cli/issues/45 from December could be addressed? I was really hoping to use this feature and found out that the

--project

flag on GrowthBook CLI isn't actually implemented.

There is a bug with segments. They will not work for us at all. We get

Syntax error: Expected ")" but got keyword WHERE at [83:13]

The generated query has two

where

keywords instead of an

and

FROM
              `ga4-explorations`.`analytics_383872824`.`events_*`
            WHERE
              (
                (_TABLE_SUFFIX BETWEEN '20241115' AND '20250214')
                OR (
                  _TABLE_SUFFIX BETWEEN 'intraday_20241115' AND 'intraday_20250214'
                )
              )
            WHERE
              customer_type != 'pro'

Hi guys. We're a self-hosted paying customer, ArtWorkout. I come here to say that we love this product. But. As a founder I'm unhappy with the redesign you made recently. The test statuses now are undistinguishable from each other and I used a "change test name" button a lot to highlight some tests or changes that have to be made on them. Basically I use them similar to Trello cards that can have their names changed. And now this button is hidden and that really frustrates me. Thanks for listening

Hi guys! We started to use GB a few months ago on a NextJS app successfully and we now want to use it on a PHP site but we’re having issue with the PHP-SDK related to PHP 8.4. It looks like this pull-request would fix our issue, can someone look at it? https://github.com/growthbook/growthbook-php/pull/29

Wouldn’t it be great to upgrade the plain textarea fields for JS + CSS with something like VSCode’s Monaco editor ? Syntax highlighting, autocompletion, find/replace, the list goes on… I always find myself copying to and from my IDE because editing code in a textarea field just doesn’t cut it 😅

Hey, picking up a bug we see since a while now (initially reached out about this in December 24): We get

Query execution was interupted. Please try again.

error messages (in the Queries overview and a red warning symbol), but I can see in our query engine that the queries actually ran successfully in a reasonable timeframe and also GrowthBook gives it a tick + shows the data (but also an error message) 🤔 We would really appreciate a fix here as the error messages make stakeholders lose trust in the data 🙏 CC @ripe-tiger-2213

, GrowthBook can migrate to Discord which is free forever and it keeps chats for the eternity. Many open source projects migrated to Discord because of that feature. It would be awesome if you guys can consider it.

Would love a way to retain my login session for longer, it seems after only a few hours I have to re-login again. A week would be great, longer would be better.

Since some update of GB site, my targeting rules looks unclear in each experiment. Please, fix it.

A few times it's happened where I've been trying to tie together a Fact Table SQL query and it seems to lag a bit, but doesn't change anything in the UI, but then we look at our Postgres CPU and it is pinned to 99%. It would be great to figure out how to implement some sort of catch or timeout for the query process so we're not unknowingly killing our database with no information from the GB side.

Hello Growthbook Team, First of all a big thank you to you guys for such an awesome and simple AB testing tool! It's been a life saver for me. However, as a feedback, please work on your documentation part with code examples. I haven't been able to find any demo codebase or working example of sticky bucketing anywhere. Documentation as well is very theoretical on it. Also, it would be great if you could add an API doc section where you add all the methods and properties of growthbook instance available to view at one place, like how you have API docs for rest API part of it

Hey quick feedback - really enjoying GrowthBook so far - I think I found a quick bug on Edit Analysis. When you manually edit the End date, it looks like the datepicker is rendering under the form (z-index lower than popup and overlay): Windows chrome incognito mode. You can see the popup hidden in the bottom right, that hides/shows based on clicking on the date form below End (UTC)

Hi! I have a question about calculating retention. Right now the rules are such that it is essentially considered Rolling Retention when we have the x+ days rule. Can you make it so that there is a restriction on the other side please? Not only >=, but also <. We have metrics RD1, RD7, RD1-7 where there are clear limits on when they must complete. Other than that, it would be really cool if it would be possible to pick a custom start event for retention. As an example: sometimes it's more correct for us to count those who have onboarded rather than from the first launch of the app. Plus, retention is usually counted from the first launch, not a specific event, so it won't be quite right for older users.

I also don't really like the way queries are written in GB, they don't look very optimal, at least for my cases with ClickHouse. Often a query is made WITH first the full table, then from it the data is filtered by conditions for the experiment. Here I showed how the query is sped up by half simply by moving the filters around, using an example of one of the queries I copied from GB: https://www.diffchecker.com/QVthzUpn/ Anyway, GB is great!

Feedback regarding scheduling of experiments (tried searching on this, but couldn't find anything): As we are getting more comfortable with the tool, we now wanted to start working with scheduling experiments to reduce the manual work of having to remember to turn on and off the experiment. I had two experiments that were supposed to start this morning using the feature, but I noticed that they never went live and the scheduling was gone from the feature. When asking the support AI it said that I must first put the experiments as running since the feature rule can't move it from draft and then the scheduling should work. I've attached two images of what it should look like from my understanding. The issue with this approach is that it really doesn't (imo) make sense to have an experiment as running if it's not running. There is nothing on the experiment page either that suggests that it's scheduled to start running at a specific time either, which makes it more confusing. The same goes for when the rule is disabled. The experiment is still "running". If this is not already something you have in your backlog to look over, i'd be more than happy to submit a github request 🚀

Is this a typo in the documentation? https://docs.growthbook.io/statistics/multiple-corrections

We can write both as follows, where V is the number of tests that are statistically significant but are false positives and R are the number of tests that are statistically significant.
False Discovery Rate=FDR=E[V/(V+R)]

Should be V/R?

Has simulate feature where you can enter values and see what features/experiments are assigned to become a part of premium plan? I see "simulate" is locked but no mentions of it under https://www.growthbook.io/pricing pricing plan comparison. Documentation does not mention it either https://docs.growthbook.io/features/rules#simulation where as for "archetypes" it's clearly stated.

Hi! Tried to create a segment from the actual table, but there is too much data and the query crashes due to lack of memory. We have a materialized view that we use for Experiment Assignment Query, and those tables are a million times smaller. Could you add it to the list of actual tables please?

Hi Growthbook, We are using slack notifications and I was wondering if it was possible to make a request to get an experment/phase started/stopped notification? This would help our ops folks. We are self-hosted/enterprise.

Hi! I’ve come across what appears to be a bug in GrowthBook’s handling of conversion window settings for metrics. While the metric delay (burn-in) is correctly reflected in the auto-generated SQL (e.g.

m.timestamp >= d.timestamp + INTERVAL '1 hour'

), the conversion_window (e.g. +

AND m.timestamp <= d.timestamp + INTERVAL '24 hours'

) is consistently missing, even when clearly configured in the UI and stored in the metric’s JSON (inspected via Web UI). I’ve tested: • Updating existing metrics → conversion_window is ignored. • Creating new metrics via the UI → still ignored. • Metrics (self-labeled) “in 90d”, “in 48h”, etc. → do not apply a user-relative time cap in the SQL, and we’ve therefore been consistently misreporting these numbers under the assumption that the window was respected. • Burn-in does work reliably, so this appears to be a partial implementation. Interestingly, I found one older metric that does apply the conversion window correctly, so it might be related to how/when the metric was created. Let me know if you’d like reproduction steps or example SQL — happy to share more. We're using GrowthBook Cloud w/ Build: 3.6.0+2d22835 (2025-06-10) Thanks in advance!

Hi, I cannot make changes using the visual editor. Any clue what I am doing wrong? I have made a quick video to showcase the issue: https://files.ghaus.me/a2xUcfqn

I’m getting this error from the “Explore time series” button
