Getting started is three steps: 1. Connect GitHub, 2. Select Runners, 3. Enjoy more efficient builds. Companies deploy faster with Tenki.

## Capabilities — Engineered for speed. Proven in production.

- **Works with your existing setup** — Work the same way you do today, but save money and get better performance.
- **x64 and macOS supported** — Engineers can leverage Tenki's benefits regardless of operating system.
- **One Line of Change** — An effortless way to migrate, just by changing a single value in your YAML file.
- **Runs on bare metal** — Runners operate on Tenki-owned servers for lower latency and reduced costs.
- **Keep your code isolated and safe** — Tenki runners operate on ephemeral VMs, removing supply chain threats.

> "I switched my GitHub Actions to Tenki Cloud in just two minutes: no config changes, no friction. My builds now run faster and cost less thanks to Tenki's bare metal runners. CI/CD finally feels fast, fair, and affordable." — Ayush Gharat, Founder & CEO, Binary Brain

## FAQs

### What are Tenki runners?

Tenki runners are self-hosted-style GitHub Actions runners managed by Tenki on bare-metal Linux x64 and macOS infrastructure, designed to be a drop-in alternative to GitHub-hosted runners. You point your workflow at a Tenki runner label by changing the `runs-on` value in your YAML, and your existing GitHub Actions jobs run unmodified on faster, cheaper hardware. There is no agent to install on your own servers and no infrastructure for your team to operate.

### How do I switch a workflow from GitHub-hosted runners to Tenki?

Change the `runs-on` value in your workflow YAML to a Tenki runner label (for example replace `ubuntu-latest` with `tenki-ubuntu-2x-4gb`) and your next workflow run executes on Tenki. No other changes are required: Actions, secrets, caching, matrix strategies, reusable workflows, and container jobs all continue to work. The [Runners quickstart](https://tenki.cloud/docs/runners/quickstart.md) walks through the migration wizard, which can also open the YAML pull request for you.

### Are Tenki runners isolated and secure?

Yes. Every job runs in a single-tenant ephemeral virtual machine with a fresh kernel, fresh disk, and isolated network namespace, and the VM is destroyed at the end of the workflow. Jobs cannot inspect or interfere with one another, and job-time secrets never leave the runner VM boundary. Tenki operates under the SOC 2 Type II program of its parent company Luxor Technology. See the [Security page](https://tenki.cloud/company/security) for the full security program, encryption details, incident-response process, and report request flow.

### How much do Tenki runners cost compared to GitHub-hosted runners?

Tenki Linux x64 runners are designed to deliver the same workflows up to 60% cheaper and 30% faster than GitHub-hosted runners on average, with a usage-based, per-minute price. Pricing is published on the [Pricing page](https://tenki.cloud/pricing) and every account starts with free monthly credits, no credit card required to begin. Committed-use discounts are available for teams with steady or high-volume workloads.

### Which operating systems and architectures do Tenki runners support?

Tenki supports Linux on x64 and macOS on Apple Silicon (M-series) hardware, covering CI workloads for both general-purpose backend/web pipelines and teams that build, test, or sign Apple platform code. Linux runners cover the same Ubuntu image surface as standard GitHub Actions, so most workflows that target `ubuntu-latest` migrate without source changes. For macOS specifics (Xcode toolchains, keychain handling, and signing) see the [macOS runners docs](https://tenki.cloud/docs/runners/macos-runners.md).
