*Compared to GitHub-hosted Runners

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!

Testimonials

Here’s what engineers
and leaders are saying.

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.

Jonatan Dutra

Software QA Engineer

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.

Sandro Marton

DevOps Engineer

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.

Jan Beck

Head of Firmware

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.

Thomas Sanlis

Indie Maker

I finally had the chance to dive into Tenki, and I’m really impressed. 🚀 The platform is clean, intuitive, and technically solid. Navigation feels seamless, performance is smooth, and the overall UX is highly optimized.

Riya Pathel

Frontend Developer

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.

Been using Tenki for a month now and it's incredible. 2 x faster than github and 90% cheaper. But the winner has been excellent support from Hayssem and the team. Highly recommended!

Daniel Donaldson

Software Engineering Manager @Siyavula

Migrating to Tenki was a breeze. It automatically opened a PR to migrate everything, and it just worked perfectly! My workflows have sped up by 2-3x!

I switched my GitHub Actions to Tenki Cloud in just two minutes: no config changes, no friction. My builds now run 30% faster and cost 90% less thanks to Tenki’s bare metal runners. CI/CD finally feels fast, fair, and affordable.

Ayush Gharat

Founder & CEO @The Binary Brain

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.
