## Results — The numbers behind the claims.

**Code Reviewer:** a live benchmark leaderboard ("Tenki leads recall and F1 across every real bug") comparing Tenki Code Reviewer against other AI review tools on recall, precision, and F1 over real bugs. Data is fetched at build/runtime; see the full methodology and current numbers in the [Benchmark Report](https://tenki.cloud/benchmarks/code-reviewer).

**Runners:** Tenki vs GitHub-hosted runner comparisons on real workloads.

x64 (Tenki vs GitHub):

**Sandboxes:** SDK code samples in TypeScript (`@tenkicloud/sandbox`), Go (`github.com/LuxorLabs/tenki-sdk-go/sandbox`), and Python (`tenki`) showing how to create a sandbox and exec commands. Under 2s provisioning. No cold starts. Agents get a live environment before the next token is generated. [Explore Sandboxes](https://tenki.cloud/products/sandbox)

## Capabilities — Tenki builds on your workflows: no changes, no reconfiguration, just improvements.

- **Your code isolated and safe** — Tenki Runners operate on ephemeral VMs, removing supply chain threats.
- **Understands your code base** — Tenki Code Reviewer understands your codebase for precise reviews.
- **Raises critical and high issues** — Severity is tunable: silence noise, surface only the issues that matter for merge.
- **Works with your existing setup** — Work the same way you do today, but save money and get better performance.
- **No training on your data** — Tenki will never use your inputs or code reviews to train its models.
- **Runs on bare metal** — Runners operate on Tenki-owned servers for lower latency and reduced costs.

## Testimonials

Quotes from founders, CTOs, and engineering leads about faster builds, lower CI costs, and easy migration. For example: "It feels just like using GitHub Actions with their hosted-runners but only much more affordable" (Arnar Þór Sveinsson, Co-founder & CTO) and "2x faster than github and cheaper... excellent support" (Daniel Donaldson, SWE Manager).

## FAQs

### What is Tenki Runners and how does it compare to GitHub Runners?

Tenki is a high-performance, GitHub Actions-compatible runner platform: a faster, more flexible, and more cost-effective alternative to GitHub-hosted runners. Onboarding takes under 2 minutes with a 2-click migration tool that requires no workflow changes. Tenki delivers up to 60% cheaper pricing, 30% faster job completion, and full GitHub Actions compatibility.

### What is Tenki Code Reviewer?

An AI-powered code review assistant for GitHub pull requests. It automatically analyzes code changes, identifies potential bugs, security issues, and performance risks, and provides contextual feedback directly inside GitHub.

### What is Tenki Sandbox?

Tenki Sandbox gives AI coding agents an isolated cloud machine to write, run, and test code without touching your own systems. Sandboxes boot in under two seconds with no cold starts. Drive them through the SDK or the Agentic Development Environment (ADE); pay only for the compute you use, billed per second.

### Is Tenki secure and compliant?

Tenki operates under the SOC 2 Type II program of its parent company Luxor Technology, and is aligning data handling with GDPR principles (full compliance on the roadmap). Infrastructure runs in SOC 2 and ISO 27001 certified data centers, and every CI job runs in an ephemeral VM destroyed after completion.

### Can I try Tenki for free?

Yes. Every Tenki Starter workspace includes $10 in free credits each month, automatically renewed on the 1st — no strings attached.

### What pricing models are offered?

Pricing is simple and usage-based: you only pay for the runner time you use. The Starter plan includes $10 in free monthly credits, no credit card required. Committed-use discounts are available for steady or high-volume workloads. See the [Pricing page](https://tenki.cloud/pricing) or contact hello@tenki.cloud.

### What platform integrations does Tenki support today?

Currently GitHub only. Support for platforms like GitLab and Bitbucket is being explored — reach out to hello@tenki.cloud with requests.

### Who is Tenki designed for?

Performance-focused startups, DevOps and platform teams at SaaS companies, solo developers, and growing engineering teams that need fast, reliable, scalable GitHub Actions runners. No commitments, no locked features, and $10 in free monthly credits.
