2x faster GitHub Actions with 60% cost savings

As of 29 August 2026, Blacksmith has a free plan and paid plans start at $0.004/minute. Blacksmith is a GitHub Actions runner service that functions as a drop-in replacement for standard GitHub-hosted runners. Softwr lists it under Developer Tools. Blacksmith is available on Linux, Windows, macOS.

Overview

What Blacksmith does

Blacksmith accelerates CI/CD pipelines by providing faster, more cost-effective GitHub Actions runners as a drop-in replacement. The platform runs GitHub Actions on bare metal gaming CPUs with high single-core performance, features co-located dependency caching, and includes managed Docker layer persistence. Runners are available across multiple operating systems including Ubuntu x64 (0.004/min), Ubuntu ARM (0.0025/min), Windows x64 (0.008/min), and macOS M4 (0.08/min), each offering similar cost savings compared to GitHub's standard runners. All plans include a free tier of 3,000 minutes per month, an observability console for debugging CI pipelines, and support for Docker layer caching and sticky disks as add-ons. The platform is trusted by over 3,000 organizations and processes over 50 million jobs monthly. Enterprise customers receive custom pricing, 99.9% SLA guarantees, 24/7 priority support, dedicated Slack channels, white-glove onboarding, and CI optimization consulting.

What people use it for

  • Replacing GitHub Actions runners with faster, cheaper infrastructure
  • Accelerating CI build times for organizations with heavy CI load
  • Reducing cloud spend on GitHub Actions by 60% or more
  • Supporting ARM architecture builds without GitHub runners

  • Per-minute pricing model requires estimating usage to predict costs
  • macOS M4 pricing ($0.08/min) is significantly higher than GitHub Actions
  • Docker layer caching and sticky disks are paid add-ons at $0.50/GB/mo
  • Static IP add-on costs $100/IP/mo
