BuildJet Is Shutting Down: Migrate to WarpBuild

On February 6, 2026, BuildJet announced that it is shutting down. The service will stop running jobs on March 31, 2026, and new signups have already been halted. If you're a BuildJet customer, you need to migrate your workflows before the deadline.

BuildJet was one of the first to prove that teams needed faster GitHub Actions runners. They showed that the default 2-core VMs weren't cutting it — and thousands of teams agreed. Credit where it's due: BuildJet helped establish the market for third-party CI runners.

Teams with demanding CI workloads still need more — snapshots, unlimited concurrency, multi-cloud infrastructure, and fast caching at scale. This is even more essential now, with so much more code being generated everyday by AI tools that CI is fast becoming the bottleneck. That's exactly where WarpBuild comes in.

What This Means for Your Team

Here's the timeline:

• February 6, 2026: New signups halted. All concurrency subscriptions are now free.
• March 31, 2026: BuildJet stops running jobs entirely.

If your workflows use buildjet-* runner labels, they will fail after March 31. You need to migrate before then.

You have two options: go back to GitHub's stock runners, or move to WarpBuild and keep the fast CI experience your team is used to.

Why Not Just Go Back to GitHub Runners?

If your team chose BuildJet, it was because you needed faster builds. That need doesn't go away when BuildJet does.

GitHub's default runners are 2-core shared VMs, and while their larger runners offer more CPU, they still lack features that modern CI demands — snapshots, bring-your-own-cloud, unlimited concurrency, and fast caching at scale.

If fast CI matters to your team, it's worth looking at what's available today.

Why WarpBuild

WarpBuild is a natural next step for BuildJet users. Same one-line setup, same drop-in replacement model — with additional capabilities on top. For a detailed feature-by-feature comparison, see our BuildJet vs WarpBuild comparison. Here's what matters most:

Snapshots: 2-10x Faster Builds

WarpBuild provides fast hardware plus snapshots — the ability to save and restore full VM state across builds. Instead of reinstalling dependencies, rebuilding caches, and setting up environments from scratch every run, your CI starts exactly where it left off. This is the single biggest unlock for CI performance.

Unlimited Concurrency

WarpBuild has no concurrency limits and no extra fees. Run as many parallel jobs as your workflows need — no caps, no add-on pricing.

Fast, Unlimited Cache

WarpBuild provides unlimited cache storage with 7-day retention from last access, designed to stay fast even at 100+ concurrent jobs. It works with the standard actions/cache action — no proprietary tooling needed.

Multi-Cloud and 29+ Regions

WarpBuild supports AWS, GCP, and Azure across 29+ regions globally. Pick the region closest to your source code and artifact storage to minimize latency and data transfer costs.

Bring Your Own Cloud (BYOC)

For teams that want maximum control and savings, WarpBuild BYOC lets you run CI runners in your own AWS, GCP, or Azure account. WarpBuild manages the control plane while runners execute in your infrastructure — giving you 10x cost savings compared to hosted options, plus static IPs, custom images, and full network control. BuildJet never offered this.

Full OS Coverage

BuildJet supported Ubuntu 20.04 and 22.04 only. WarpBuild runs Ubuntu 20.04/22.04/24.04, Windows Server 2022/2025, and macOS 13/14/15/26 on M4 Pro hardware. Whatever your workflows need, WarpBuild covers it.

Enterprise Ready

WarpBuild is SOC2 Type 2 compliant, supports SSO through Microsoft Entra ID, Google, Okta, Auth0, and JumpCloud, and offers a 99.9% SLA with dedicated support. BuildJet was not SOC2 compliant and charged $500 just for a security assessment.

Active Development

BuildJet's product was essentially unchanged for over 2.5 years before the shutdown announcement. WarpBuild ships new features every week — remote Docker builders, configurable disks, analytics dashboards, and more. You're migrating to a platform that's investing in the future, not winding down.

Migrating from BuildJet to WarpBuild

Migration takes under 10 minutes for most teams. Here's how:

1. Sign up and install the WarpBuild bot

Create an account at app.warpbuild.com and install the WarpBuild GitHub bot on your repositories. See the quick start guide for details.

2. Update your runner labels

Replace BuildJet runner labels with their WarpBuild equivalents in your workflow files:

For a full list of available runner configurations, see the cloud runners documentation.

Here's what the change looks like in a workflow file:

jobs:
  build:
    runs-on: buildjet-4vcpu-ubuntu-2204
    steps:
      - uses: actions/checkout@v4
      - run: make build

jobs:
  build:
    runs-on: warp-ubuntu-2204-x64-4x
    steps:
      - uses: actions/checkout@v4
      - run: make build

3. Swap the cache action

If you're using buildjet/cache, replace it with actions/cache. WarpBuild's caching infrastructure is fully compatible with the standard GitHub Actions cache action.

- uses: buildjet/cache@v4

- uses: actions/cache@v4

That's it. Your workflows will now run on WarpBuild's infrastructure with faster hardware, better caching, and no concurrency limits.

Get Started

BuildJet helped prove that teams deserve faster CI. WarpBuild is where that journey continues — with snapshots, unlimited concurrency, multi-cloud support, and pricing that's 50% cheaper than GitHub.

Don't wait until March 31. Sign up for WarpBuild and migrate your workflows today. For a deeper technical comparison, read our full BuildJet vs WarpBuild breakdown.
