Fireactions: Self-Host GitHub Runners Easily in 2025

Why Self-Host GitHub Runners?

Tired of GitHub-hosted runners hitting limits on minutes, costs, or custom hardware? Self-hosting gives you full control, faster builds, cheaper scaling, and hardware tuned to your stack. But setup? A nightmare of VMs, scaling logic, and security holes.

Enter Fireactions: The open-source orchestrator that makes self-hosting GitHub runners as effortless as clicking “Run.” Built by Hostinger for high-volume CI/CD, it uses Firecracker microVMs for isolation without the sweat. In 2025, with CI/CD demands exploding, Fireactions is your BYOM (Bring Your Own Metal) secret weapon.

What is Fireactions?

Fire actions is a free, open-source tool that automates self-hosted GitHub runners in ephemeral, Firecracker-based virtual machines. No more wrestling with persistent VMs or manual scaling, Fireactions spins up runners on-demand, runs your jobs, then shreds them clean.

Key vibe: Like GitHub-hosted runners, but on your hardware. Secure (microVM isolation beats containers), fast (sub-second spins), and scalable (pool-based auto-scaling).

Launched in late 2024, Fire actions has devs buzzing on X for simplifying what used to take weeks.

Key Features: What Makes It Stand Out

Fireactions isn’t just another runner, it’s a full orchestrator. Here’s the 2025 lineup:

How Fire actions Works: Ephemeral Runners Explained

Under the hood, Fire actions listens for GitHub webhooks. Job queued? It:

1. Requests a GitHub token.
2. Fires up a Firecracker microVM (lightweight kernel, containerd for OCI images).
3. Installs the runner app inside.
4. Executes your workflow.
5. Nukes the VM—poof, clean slate.

No persistent state means hacker-proof isolation. Read: GitHub’s self-hosted docs for basics.

Step-by-Step: Install Fire actions in 10 Minutes

Ready to deploy Fire actions? Here’s the foolproof 2025 guide (tested on Ubuntu 22.04+).

1. Prep Your Server: Bare metal or VM with 4GB+ RAM, Docker/containerd.
2. Clone & Install:
   text

   git clone https://github.com/hostinger/fireactions
   cd fireactions
   ./install.sh --github-app-id=YOUR_APP_ID --github-app-key-file=private-key.pem --github-organization=YOUR_ORG --containerd-snapshotter-device=/dev/nvme0n1
   (Defaults: Firecracker 1.4.1, kernel 5.10.)
3. Config Pool: Edit config.yaml for min/max runners (e.g., default pool: min 1, max 10).
4. Start Service: systemctl start fireactions.
5. Test Workflow: Add to .github/workflows/test.yaml:
   YAML

   name: Fire, actions Test
   on: [push]
   jobs:
     test:
       runs-on: [self-hosted, fire actions]
       steps:
         - run: echo "Hello, Fire actions!"
6. Verify: Push code, watch your first ephemeral runner spin.
