# Make a devtool agents want > Source: > Published: 2026-06-26 05:48:14+00:00 # Make a devtool agents want I created [Preseason.ai](https://www.preseason.ai/) because I was curious about how much power current LLMs have in recommending developer tools to people vibe coding their own web apps. Vibe coding is obviously in a crazy growth phase, with some companies going from zero to hundreds of millions in revenue in less than a year. And with that, they are also pushing along a set of specific dev tool companies with a similar trajectory. So I wanted to track this and built [an open-source benchmark](https://github.com/betocmn/preseason) for it. Every day, Preseason sends prompts to the top open and closed-source LLMs from the main labs and measures which developer tools they recommend. For example: - What database do they recommend? - What authentication provider? - What UI framework? - What email provider? - What search provider? - LLM Observability - And so on. It has been very interesting already. **One example is email.** As you can see below, there is still a lot of competition in this category, with SendGrid and other legacy providers still showing up strongly. But you can also clearly see Resend as a modern startup that is very well designed, has great documentation, and seems to be growing very fast. I would not be surprised if a meaningful part of that growth is now coming from LLM recommendations. Imagine someone starting a new SaaS for a small business right now. They need to send emails to their customers. A lot of the time, the LLM is probably just recommending Resend and sending them a new customer. That is pretty cool. **Another example is databases.** **Another example is search.** **Another example is LLM observability.** The project is [open source](https://github.com/betocmn/preseason), so please feel free to open a PR if you have a good idea for how to make the measurement more robust. I will keep tracking this as I go and post updates from time to time.
