Hey I submitted through the contact form but not sure if it went through: I have an existing nullable VARCHAR(64) column named business_fingerprint on an existing production table. I need to add a database-level UNIQUE constraint to that existing column while continuing to allow multiple existing NULL values.

A: Hi,
You have three supported ways to add this UNIQUE constraint without recreating the table or losing any data:
Method 1: Using the "Run SQL" Button in the Dashboard (Direct)
1. Navigate to your database and open the "Edit Database" page.
2. In the top-right header, click the "Run SQL" button.
3. Run the following standard ALTER TABLE statement:
I’ve been really impressed with how quickly I can get a backend up and running with NoCodeBackend. The MCP integration looks especially interesting.
Are you planning to expand the MCP capabilities further? It would be really cool to let AI agents not only query the database, but also help manage things like authentication, RLS policies, API configuration, etc.

A: Thank you so much! We’re really glad you’re enjoying NoCodeBackend and finding the MCP integration useful.
Actually, many of the capabilities you mentioned are already covered as part of our MCP integration. AI agents can work with the database and also interact with backend capabilities such as authentication, RLS policies, and API configuration.
You stated that each workspace supports 15 parallel in-flight requests plus a 30-request FIFO buffer. Is this concurrency limit shared across my entire AppSumo workspace and all databases, or does each database get its own 15 + 30 concurrency pool? For example, on Tier 5 with 100 active databases used by 100 separate client apps, would all 100 apps together share only 15 active concurrent requests?

A: Hi Solu,
Great question!
The short answer is: No, your 100 apps will not share 15 requests.
Each database in NoCodeBackend has its own unique secret key. Our traffic limit (15 concurrent requests + 30 waiting queue) is tied to that specific key.
This means each of your 100 databases gets its own separate 15 concurrent slots.
If App #1 gets hit with heavy traffic and maxes out its 15 slots,...
Another question: I have the original grandfathered Tier 2 AppSumo plan with unlimited records per database. If I upgrade now to Tier 5, will all 250 databases available to my Tier 5 account, including databases I create in the future, retain unlimited records per database? Tier 5 + all 250 database slots + future databases + unlimited records?
Q: Until Sept 25, a user's email alone let others see their databases and secret keys. Will you warn and investigate?
Until Sept 25, a serious bug let any registered user — free or paid — open any other user's account with just that user's email address. They could see every database that person built and its secret key: full control to read, change, or delete everything inside.
I reported it privately with steps to reproduce; it is now fixed.
But a quiet fix is not enough. My questions:

Thank you for your post. We take security and platform integrity very seriously. Because your post characterizes this as a catastrophic platform-wide exploit where anyone could "open any account and delete everything," we want to address your questions transparently and set the record straight for all users and prospective customers.

We did offer the user a $250 coupon code in recognition of their work. The concern from their end appears to be that they were expecting a refund of $1,500+ directly to their account. We declined that request because they had already been using the tool for more than nine months.

Yes you will retain your original limits as per your original plan.
Q: Addons Custom Domains
Hey, after the deal ends, is it still possible to add custom domains because I could not see it in nocodebackend Plans & limits
Riya_NoCodeBackend
Sep 25, 2026A: Hi,
Custom domains cannot be purchased after this AppSumo campaign ends. They are currently only available through AppSumo during this deal.
thanks,

Thank you for those questions.
Thanks for reporting it. What you did is important and shows how honest a company is. You should actually have been rewarded for it, not ignored.

@Riya This is exactly the kind of transparency I was hoping for. Thank you very much for your professional response. It makes sense and builds trust.
