从 0 到 4000 万美元 ARR：揭秘驱动 Bolt.new 的技术内幕

If you've started a new side-project recently, there's a good chance you've bumped into Bolt – a one‑prompt app builder that went viral thanks to demos that look like magic. Type a sentence, wait a few seconds, and out pops a fully running project.

如果你最近启动了一个新的 side-project，很可能已经接触过 Bolt —— 一款因演示效果宛如魔法而迅速走红的单提示应用构建器。输入一句话，稍等几秒，一个完整可运行的项目就诞生了。

From the outside, Bolt seems like an overnight success story – another startup riding the wave of the AI boom. In fact, Bolt is among the most successful startup pivots ever. An overnight success that was seven years in the making.

从外部看，Bolt 像是一夜成名的故事——又一家乘着 AI 浪潮崛起的初创公司。事实上，Bolt 是有史以来最成功的初创公司转型之一。这是一夜成名，却酝酿了七年。

This graph speaks for itself. Since that pivot in October 2024, Bolt’s users have created millions of apps, and Bolt is generating $40 million in ARR with an engineering team of just 15. A truly epic turnaround.

这张图不言自明。自 2024 年 10 月那次转型以来，Bolt 的用户已创建了数百万个应用，并以仅 15 人的工程团队实现了 4000 万美元的年经常性收入。这是一次真正史诗级的逆转。

I spoke with co‑founder and CTO Albert  Pai, and founding engineer Dominic Elm, to understand how Bolt puts the rabbit into the hat.

我与联合创始人兼 CTO Albert Pai 以及创始工程师 Dominic Elm 进行了交谈，以了解 Bolt 是如何把兔子放进帽子的。

To understand some of the technical challenges of building Bolt, let's see what happens after entering a prompt:

为了理解构建 Bolt 的一些技术挑战，让我们看看输入提示后会发生什么：

User types in a prompt, e.g. “Build a Tinder for Dogs web app”.
用户输入提示，例如 “给狗狗做一个 Tinder 网页应用”。
Prompt is sent to LLM to generate the code for the app.
Prompt 被发送给 LLM 以生成应用的代码。
In the meantime, the browser boots up WebContainer, an in-browser virtual machine where all the code will run.
与此同时，浏览器启动 We...
