Blacksmith offered lower cost and faster runners and made it easy to switch and see if those claims were true. Not only were those claims true, they continued to deliver more value with better observability for our CI/CD pipelines. That's allowed us to optimize our build pipelines so we can ship more, faster.

Nick Crohn

Staff Software Engineer at Sibi

Switching to Blacksmith's runners has been a significant upgrade for our development processes at Walnut. They are reliable, significantly faster than GitHub runners, and come at half the cost, helping us optimize both time and budget. The installation and setup were a breeze, making the transition seamless. We highly recommend Blacksmith's server runners to any team looking for a more efficient and cost-effective solution.

Igor Nahary

SRE Lead at Walnut

We switched from GitHub-hosted runners to Blacksmith and saw
decreased build times because of their better machines and caching.

Our CI costs were also cut by half.

Gautam Gupta

Co-Founder at Highbeam

Blacksmith is a no-brainer if you're using GitHub Actions. It took less than 10 mins to integrate and cut our CI time by 35% and our CI costs by 70%.

Greg Bergé

Product Engineer at GitBook

At Axelar, rust build times were constantly slowing us down.
‍‍
Blacksmith cut our rust build times from 9 mins to 3.5 mins while being 50% cheaper.

The best part was how easy it was to use Blacksmith.

Milap Sheth

Eng Team Lead at Interop Labs

Blacksmith has been great for our developer velocity - it’s much faster than GitHub runners so our team spends much less time waiting for code to build.

Advith Chelikani

Co-Founder at Pylon

Switching to Blacksmith was a quick one-line change and we saw an immediate 30% improvement in CI time. It was a noticeable upgrade and made it fun to push commit-by-commit again

Gabriel P Samson

Founding Engineer at Slope

Since switching to Blacksmith, our build times are over 65% faster, our costs have gone down and our engineers are more productive.

We couldn't be happier!
