One Line of Change

Stop wasting resources

Varying runner sizes enable your team to adapt as workflow demands fluctuate.

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.

Tenki offers a nice alternative with minimal migration effort. The combination of improved performance and dramatic cost savings makes it worth serious consideration.... I don’t see the point of using GitHub-hosted runners anymore.

Really enjoying the experience with Tenki so far! It feels just like using GitHub Actions with their hosted-runners but only much more affordable. As a bootstrapped startup, the drop in our CI costs has been a huge boost for us!

Been using Tenki for a month now and it's incredible. 2x faster than github and cheaper. But the winner has been excellent support from Hayssem and the team. Highly recommended!

We eat our own dogfood here at Luxor. The firmware team switched very early to Tenki to host our collaborative reverse-engineering tools. It's been 100% reliable.

The transition to Tenki was almost imperceptible. Just a quick config change and everything worked right away. I’ve been using it daily ever since.

I recently moved my CI/CD pipelines to Tenki Cloud, and the difference has been remarkable. Tenki truly feels built for developers, it's intuitive, transparent, and focused on performance rather than billing complexity.

Tenki has been fantastic so far, super reliable and easy to use. I don’t have any feedback right now because everything just works, but I’ll definitely continue using it and recommend it to others.

I love that Tenki runners are faster than the GitHub ubuntu-latest, and they are 1 million times faster than self-hosted ARC runners on my k3s cluster.
