Even without turnover, I've no idea how you're supposed to compete with the quality of top open source software. Maybe no one finds the bugs in your software, but they're definitely there.
C# 8.0 / .NET Core 3.x / AspNetCore / Blazor / SQLite
Of these, SQLite is arguably the most stellar example of what open source software can provide to the world.
Everything else in our stack consists of in-house primitives built upon these foundational components.
I'd love to understand why you chose that.

Effectively, our client's operations cannot rely on cloud services and all of the related last mile connectivity into their infrastructure. If AWS/Azure/et.al. go down, many of our customers are still able to continue operating without difficulty.
When I go looking for a dependency, I check the license and I have a quick read of the code.
Last time I did that was for autocomplete. I checked the most popular six options; in the space of 2 hours, I found obvious-from-reading-code bugs in all 6.
None of them had a CLA signed by contributors, so there's really no evidence their code is genuinely available under the license they claim to offer.
I wrote my own. It took about 3 hours initially plus 2-3 hours ironing out edge cases found over the following weeks. It only added 700 bytes to my bundle.
Total time spent: 1 days work. Smaller code, loads fast, free from license issues, does exactly what I want.
