Tenki vs Depot
How Tenki and Depot compare on price, performance, free tier, macOS support, and migration.
Tenki vs Depot: at a glance
Tenki and Depot both offer faster-than-GitHub CI infrastructure, but solve slightly different problems. Tenki is a full drop-in replacement for GitHub-hosted runners built on bare-metal x64 and Apple Silicon M4 Pro hardware, priced at $0.003 per minute for a 2 vCPU / 4 GB standard runner, with 1,700 free compute minutes per month for every workspace. Depot began as a faster Docker-image builder with distributed remote caching and later added GitHub Actions runners; its focus remains Docker-first workflows and build caching.
This page summarises the practical differences so you can choose the right tool for your workload.

When to choose Tenki
- You want to replace GitHub-hosted runners wholesale with bare-metal capacity.
- You need macOS runners (M4 Pro) alongside Linux and Windows.
- You care about Firecracker-level isolation between jobs.
- You want AI-powered pull-request review as part of the same product.
- You want a generous free tier (1,700 minutes/month) to evaluate without a credit card.
When to choose Depot
- Docker image builds are your bottleneck and you want an optimised remote build cache.
- You're already invested in Depot's caching layer and want to consolidate runners with it.
- You need AWS-hosted runners for regulatory or data-gravity reasons.

FAQ
Is Tenki cheaper than Depot?
On the standard 2 vCPU / 4 GB Linux profile, Tenki is $0.003 per minute. Depot's current pricing is published at depot.dev/pricing — compare the specific profile you run. Both are substantially cheaper than GitHub-hosted runners.
Can I use Tenki and Depot together?
Yes. Tenki's runners work with any third-party GitHub Action, including Depot's build-cache actions. The two are not mutually exclusive.
Does Tenki support macOS?
Yes. Tenki operates Apple M4 Pro bare-metal macOS runners for iOS, macOS, and cross-platform CI/CD workflows. Depot's macOS availability should be checked on its pricing page.
How does isolation differ?
Tenki runs every job in an ephemeral Firecracker microVM that is destroyed immediately after the job finishes — no persistent state between runs, no noisy-neighbor interference. Depot uses its own build-sandbox per job.
