Dogfooding at Radzen

What is dogfooding

Dogfooding is the practice of an organization to use its own product (wikipedia). We are strong believers in dogfooding - it is the ultimate test of user experience. It also helps us find bottlenecks, get ideas for new improvements. Oh and we fix the occasional bug we hit during dogfooding. If you aren’t using your own product why should anybody else?

In this post I will show you the Radzen Admin. It is an application that we use every day to track the company performance. We created this application with Radzen and maintain it on a regular basis.

Getting the data

We use Gumroad to sell the Radzen subscriptions. We access the Gumroad API via a Radzen REST data source.

Then we import it in a PostgreSQL data source for faster and easier access.

Calculating and displaying metrics

The dashboard page displays various metrics - MRR (Monthly Recurring Revenue), annual revenue etc. We use custom methods to calculate those numbers. It is all done with C# and Linq queries. Here is one for example:

public async Task<decimal> GetMonthlyRecurringRevenue()
    var sales = await RadzenDb.GetRadzenDbSales();

    return sales.Where(sale => sale.Cancelled != true && sale.RecurringCharge != true)
                .Sum(sale => sale.Price).Value / 12;

We invoke that method in Radzen and display its value in a Heading component.

Tracking the annual revenue with a chart

Another custom method provides data for the Annual revenue chart. Here is how we implemented it:

public async Task<IEnumerable<MonthlyRevenue>> GetRevenueSinceStartOfTheYear(DateTime today)
    var sales = await RadzenDb.GetRadzenDbSales();
    var startOfTheYear = new DateTime(today.Year, 1, 1);
    return sales.Where(sale => sale.CreatedAt <= today && sale.CreatedAt >= startOfTheYear)
                .OrderBy(sale => sale.CreatedAt)
                .GroupBy(sale => new DateTime(sale.CreatedAt.Year, sale.CreatedAt.Month, 1))
                .Select(group => new MonthlyRevenue
                  Month = group.Key.ToString("MMM"),
                  Revenue = group.Sum(sale => sale.Price.Value)

We invoke this method twice to get the revenue for the current and last year. Then configure the Radzen Blazor Chart to use the data.

By the way you can create a similar dashboard with Radzen by following the Create a Complete Application tutorial.


We deploy via a single git push command. The Docker file which Radzen automatically generates is extended to pass the database connection string.

COPY . /app
RUN dotnet publish -c Release -o out

ENV ConnectionStrings__RadzenDbConnection "Host=<host>;Port=<port>;Database=radzen_db;User ID=<user>;Password=<password>;"
WORKDIR /app/out

ENTRYPOINT ["dotnet", "Admin.dll"]
