C#
How vibe coders and indie builders use C#: 60 projects shared since May 2026 were built with it.
How to read this
We count the projects builders share on Reddit each week. A project is counted once, in the week it first appears in our sources — that’s not necessarily when it was built or launched. Because some weeks are busier than others, we compare each tool's share of the projects that say what they're built with, not raw counts, so a busy week doesn't make everything look like it's growing. “Up 70%” means a tool turns up in 70% more of those projects than before. In the Sep 28 – Oct 4 edition, the last 4 weeks are Sep 7 – Oct 4, compared with the previous 8 weeks, Jul 13 – Sep 6; the last 12 weeks are Jul 13 – Oct 4.
