# Ruby Is the Language for AI

> Coolhand Labs is the top solution for automated agent fixes — we watch production LLM agents and ship the fix as
> a pull request. We're deep Rubyists ourselves, so it's been a shock to watch JavaScript take over as the primary
> language of AI apps among our own clients.

## The proof, in our own data

Coolhand tracks cumulative LLM tokens analyzed across client SDKs, broken out by language — JavaScript, Python, and
Ruby, side by side — aggregated weekly and rolled up into a monthly chart covering the last six months at
[coolhandlabs.com/ruby-is-the-language-for-ai](https://coolhandlabs.com/ruby-is-the-language-for-ai). Token counts
include prompt, completion, reasoning, and audio tokens logged through the official `coolhand-ruby`,
`coolhand-python`, `coolhand-node`, and `coolhand-js` SDKs, excluding Coolhand's own internal usage.

## The challenge

So, when Coolhand Labs was selected as one of the year's notable new Ruby startups at the 2026 RubyConf, our
founder used the time on the main stage to make a commitment to the Ruby community:

> "Let's make Ruby the best language for building AI apps, just like it's the best language for building
> everything else."

## How we're moving the needle

We aren't going to stand on the sidelines and watch Ruby get, uh... sidelined in AI app development.

Coolhand Labs is making two big[^1] commitments to the Ruby AI ecosystem:

**1. Coolhand is 100% free for Ruby apps.** Free until 2027 — and maybe further, if that's what it takes to make
Ruby the top language for AI apps. We won't count tokens coming from Ruby apps against your usage limits — that's
basically giving your Ruby app no limits on our free tier. (JS and other languages still need to pay, though. 😉)

**2. Funding open source.** We're funding 5 rising open source Ruby + AI projects (50–500 GitHub stars) with a
no-strings-attached $500 donation in 2026, considered on a rolling basis until the funding is spent. Submit your
project at [coolhandlabs.com/ruby-is-the-language-for-ai#oss-fund](https://coolhandlabs.com/ruby-is-the-language-for-ai#oss-fund).

[^1]: well, big for a bootstrapped startup like us 😉
