My Thoughts on the Current State (Especially Quality Issues) and Future Development of Bun
Based on my experience with Bun recently, I really have a lot to say. Although I am just an ordinary developer, I feel it is necessary to express my views regarding Bun's future development. I scrolled through Bun's official X account as well as the author's personal X account, and I found that even after being acquired by Anthropic, most of the official marketing is still obsessed with the "performance" narrative, namely, repeatedly emphasizing how much processing time a new feature cuts down compared to competitors or older features. Then there are the new features. Regarding the new features, the ones that left a deep impression on me are native support for **Markdown** and Stage 3 Decorators. Stage 3 Decorators are certainly a great feature, but as for Markdown, I truly cannot understand: is rendering Markdown really the proper job of a JavaScript Runtime? From what I knew about Bun previously, it can do almost anything, from a bundler to built-in database support — I could understand those previous features as Bun's "All-in-One" strategy. But I really cannot understand the Markdown support. I feel this is no longer "All-in-One"; this is "All-in-Everything." Doing this will truly cause maintenance costs to skyrocket. Granted, Bun is now under Anthropic (acquired in December 2025), and Anthropic has a lot of money, but no amount of money can allow a team to add features limitlessly while also guaranteeing quality. That is extremely difficult. Speaking of quality. I
