I got an email that a GitHub issue I filed on a repo has been fixed. I have no memory of said issue.
Idk how I feel about this

Huge. Blacksmith has helped us reduce the CI time in MSW by x10 times (yes, you read that right). Went from 10m to 1m. An absolutely silly-easy thing to recommend.
@sequoia is leading our Series C at a $1B valuation.
We started Blacksmith in 2024 to make CI faster and less painful. In January we ran 5 million CI jobs a week. Today it's over 90 million and growing, and we’re still early.

It's so fun building the future of code validation, and we're just getting started!

I posted 2 issues to the Effect repo and they were fixed 2 hours later 🤯
github.com/Effect-TS/effe…
github.com/Effect-TS/effe…
open source as we knew it may be gone, but it's so motivating to post issues when they get fixed so fast.

I always hated the way the code looked, but I think Effect might actually be the path forward for agent-driven typescript.

Faster Go builds, so your agents can iterate even faster ⚡
Go build caching is now enabled by default for every Blacksmith org, free of charge.
Across customer CI jobs, the median Go step got 20% faster and the slowest ones got 74% faster, with one test suite dropping from 58s to 5s.
Try now, link in first comment.

Alchemy is one of my favorite projects - the way they test against real infra in CI is so cool
We were fortunate enough to have our CI accelerated and sponsored by @useblacksmith
Simply swapping to blacksmith accelerated build times by nearly 2x. We then layered on more improvements.

Realized this week I can just fix every bug, layout shift, and nit I come across. Forget the backlog, just fire off an agent to fix it, get a Proof, and ship it.

Last day in the office where @useblacksmith grew up. It saw a lot of highs and some lows over the past year. Next week, we move somewhere with room to match our ambitions. You're all invited once the coffee machine is working.

@useblacksmith We're building Proof because we're shipping fast and need to keep quality high - a core value at @useblacksmith and one of my favorite things about working here.
I shipped 35 PRs to [code]smith yesterday and used Proof to validate every change. Saves so much time.

@useblacksmith A picture/video is worth a thousand words, and I'm so tired of reading 1000 word walls of text from LLMs. Proof shows me what the change did instead of giving me another wall of text to read. It's so cool.

Creativity is still alive - makes me happy
Before it became an anvil head, [code]smith almost ended up as a hammer with eyes, a literal blacksmith, or a clanker robot.
We tried them all.
Here’s the story behind how we designed the character, brought it to life, and made room for some fun personality in a product that y seriously.

We really just want your CI to be fast!!
Container caching is now on by default for every Blacksmith org. And it’s free.
Every Docker-based CI job pulls the same images over and over: Postgres, Redis, Compose stacks, base images.
On Blacksmith, those pulls disappear. We persist each org’s Docker image store on a ges are already local when the next runner starts.
No config. No cache keys. No workflow changes.
Across six real CI jobs, this made them 25–89% faster end to end.
More details in the blog soon.
