- Blacksmith is a managed CI platform that runs GitHub Actions jobs as a drop-in replacement for GitHub-hosted runners.
More detail
- It runs jobs on dedicated bare-metal hardware with co-located caches and persistent Docker layer caching, and adds a console for observing CI pipelines.
- Best for
- Engineering teams already using GitHub Actions who want faster builds, tests and deploys without operating their own CI infrastructure, and who want per-minute CI costs below GitHub-hosted runners.
- Pricing
- Pay-as-you-go per-minute compute billing, with no monthly subscription.
More detail
- The official pricing page lists Ubuntu x64 at $0.004/min, Ubuntu ARM at $0.0025/min, Windows x64 at $0.008/min and macOS M4 at $0.08/min, each including 3,000 free minutes per month and claiming 35–75% total cost savings versus

About
- Blacksmith is a managed CI platform that runs GitHub Actions jobs as a drop-in replacement for GitHub-hosted runners.
- It runs jobs on dedicated bare-metal hardware with co-located caches and persistent Docker layer caching, and adds a console for observing CI pipelines.
What it helps with
- GitHub-hosted runners are slow to provision and slow to run builds and tests, delaying PR feedback
- CI runners from GitHub are relatively expensive per minute and costly at scale
- Cache and Docker layer downloads repeatedly cost time because they are not co-located with jobs
- CI pipelines are hard to observe, making flaky tests and slow jobs difficult to diagnose across logs
Capabilities
A practical view of what is available and where limitations apply.

What bots could verify
- • Cites specific third-party validation, including an independent Dev.to performance benchmark and Hacker News user feedback.
- • Provides balanced independent customer proof via FeaturedCustomers aggregates and named case studies.
- • Delivers thorough material risk disclosure, detailing an unexpected $1,081 overage invoice documented in an independent blog post.
What weakens trust
- • Corporate identity is incomplete, lacking legal entity registration details and executive/founder background.
- • Official pricing tiers and complete billing terms were not verified directly from primary sources.
- • Security and compliance certifications (such as SOC 2 or GDPR) were absent from the gathered search evidence.
