| Linux runners for GitHub Actions

Blaze provides fast Linux runners for your containerized CI workflows. Native ARM64 support with Docker pre-configured—build multi-arch images without emulation.

Our Linux runners come with Docker pre-installed, along with common tools like Node.js, Python, Go, and Rust.

Every Linux runner comes with common development tools pre-installed:

• * Docker – Container runtime with buildx
• * Node.js – JavaScript runtime (LTS)
• * Python – Python 3.x with pip
• * Go – Latest stable version
• * Rust – Latest stable with cargo
• * Java – OpenJDK 17 and 21
• * Git LFS – Large file storage

See the full list of pre-installed software.

Our ARM64 Linux runners are perfect for building multi-architecture Docker images:

Build native ARM64 images without QEMU emulation—up to 10x faster than cross-compilation.

Need maximum performance? Compute runners deliver enhanced CPU performance and high-speed memory for demanding workloads:

Ideal for:

• * Large Rust or C++ compilations
• * Monorepo builds with many parallel tasks
• * Memory-intensive test suites

Use compute runners by adding compute/ to your runner tag:

jobs:
  build:
    # Standard runner (1 unit)
    runs-on: blaze/ubuntu-24.04
    # Compute runner (2 units)
    runs-on: blaze/compute/ubuntu-24.04

Compute runners use 2x units for the same vCPU/RAM, but deliver significantly faster single-threaded performance.

Blaze uses a unit-based pricing model. Each unit costs a fixed monthly rate with unlimited minutes:

Annual billing saves an additional 20%. View full pricing.

Add Blaze runners to your workflow with a single line:

jobs:
  build:
    runs-on: blaze/ubuntu-24.04
    steps:
      - uses: actions/checkout@v4
      - run: docker build -t myapp .

All your existing workflow steps, caching, and secrets work exactly the same.
