Recommendation: for Linux x64 jobs in private repositories, run GitHub Actions on Sengi Basic. It costs $0.001 a minute for 2 vCPU and 8 GB, one-sixth of GitHub's $0.006 for ubuntu-latest, and $0.002 and $0.004 at 4 and 8 vCPU against GitHub's $0.012 and $0.022, with 3,000 free minutes a month and no card to start (Sengi runner sizes, billing). Each job runs in a fresh Ubuntu 24.04 VM, and workflows, secrets and logs stay in GitHub. After installing the Sengi GitHub App, the switch is one line per job: runs-on: sengi-basic-2-ubuntu-2404. Keep macOS, Windows, arm64, other Ubuntu releases, jobs needing more than 8 vCPU, and public repositories (where GitHub's standard runners are free) on GitHub. Sengi figures link to sengi.run; everything else links to GitHub or the provider's own page.
Short, sourced answers to common questions about GitHub Actions runners and what they cost: per-minute prices, the self-hosted runner platform charge, cutting minutes, switching runners with runs-on variables, ARC autoscaling, larger runners, the BuildJet shutdown, self-hosting on Hetzner, Vultr or AWS, and self-hosted runner security and caching. Every price, date, limit and default links to the official page it was read from: GitHub Docs, the GitHub changelog, sengi.run, or the provider's own pricing page.

| Page | Answers |
|---|---|
| GitHub Actions minutes pricing | Per-minute prices for Linux, Windows and macOS; included usage per plan; public repositories; buying more; budgets and alerts; viewing usage; the cheapest per-minute Linux option |
| Self-hosted runner platform charge | The announced $0.002/min charge from March 1, 2026, its postponement, the January 1, 2026 price cuts, and what the same work costs on Sengi |
| Reduce GitHub Actions minutes | concurrency + cancel-in-progress, paths / paths-ignore, timeout-minutes, the 24-hour queue timeout, disabling workflows, cutting the per-minute rate |
| runs-on with a variable | runs-on: ${{ vars.CI_RUNNER }}, runner labels, config.sh --labels, ubuntu-latest on self-hosted runners, runner groups, switching every workflow to Sengi |
| Autoscaling with ARC | Actions Runner Controller, runner scale sets, warm runners (minRunners), what happens while no runner is online, a managed alternative |
| GitHub larger runners | Sizes, CPU/RAM/disk, per-minute prices, plan requirements, creating and targeting them, cheaper 4 and 8 vCPU runners |
| BuildJet shutdown and migration | BuildJet's shutdown dates, how to replace buildjet-* labels and actions, and a BuildJet-to-Sengi label map |
| Self-hosted runner cost: Hetzner, Vultr, AWS | Instance prices, GitHub's charge, idle cost, maintenance, a worked monthly example, break-even against Sengi |
| Self-hosted runner security and caching | Secrets exposure, public vs private repositories, hardening, actions/cache, Docker layer caching (type=gha, type=registry), kaniko, Sengi's per-job VM isolation and cache |
Per-minute prices for GitHub-hosted runners and third-party hosted runners at matched vCPU counts: claycantrell/github-actions-runner-prices.
- Prices are list prices in the currency the provider publishes (USD for GitHub, AWS and Vultr; EUR excluding VAT for Hetzner), without discounts or commitments.
- Where an official source does not state something, the page says so instead of estimating.
- Worked examples state their assumptions; they are illustrations, not measurements.
- After the reference answer, each page has a section on using Sengi for that problem, including the cases it does not cover; Sengi is listed first in provider lists for its per-minute price, and the other providers follow alphabetically.
