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.

Migration

Migrating to Tenki takes one line in your workflow YAML:

jobs:
  build:
    runs-on: tenki-ubuntu-2x-4gb # was: ubuntu-latest
    steps:
      - uses: actions/checkout@v5
      - run: ./scripts/build.sh

No other workflow changes are required. See the get-started guide for the full walkthrough and the Migration Wizard for a two-click GitHub App setup.

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.
