WarpBuild
WarpBuild: faster GitHub Actions runners — 2x quicker CI at 50% lower cost per minute.
WarpBuild is the most direct answer to GitHub Actions queue pain, and it's cheap enough to trial on a whim — one line in your workflow, no credit card. Its edge over GitHub-hosted runners is caching and snapshots, not just raw CPU speed. The catch is scope: GitHub-only, ephemeral runners, and line-item add-ons that can bite very small projects.

Skip WarpBuild if you don't run GitHub Actions — nothing else is supported — or if your repos push rarely and build fast, where flat bundled GitHub minutes undercut per-minute billing plus cache and snapshot line items.
Cache storage bills at $0.20 per GB-month on top of per-minute runner rates, so unlimited cache size still has a monthly storage cost attached.
WarpBuild fits GitHub Actions teams at any size that care about per-minute economics, but the sweet spot is mid-size to large orgs running high job volume where BYOC at $0.002/min or arm64 Linux at $0.003/min beats GitHub's bundled minutes. Solo projects with occasional builds usually pay more than GitHub's included minutes. Against BuildJet (closed March 31, 2026) and self-hosted actions-runner-controller, Enterprise claims a guaranteed 40% infra cost saving over ARC on Kubernetes.

About WarpBuild
WarpBuild swaps GitHub-hosted runners for faster, cheaper machines without a migration project. You point your workflow file at WarpBuild and the same GitHub Actions jobs run on their infrastructure — Linux x86-64 and ARM64 from 2vCPU/8GB up to 32vCPU/128GB, ARM64 on Apple Silicon at 6vCPU/14GB and 12vCPU/28GB, Windows x86-64 from 4 to 32 vCPU, macOS M4 Pro at 6vCPU/14GB and 12vCPU/28GB, plus remote Docker builders from 16vCPU all the way to 192vCPU/384GB with up to 2TB of attached disk. The economics are the pitch: 2x faster builds, roughly 50% lower cost per minute, unlimited job concurrency with instant autoscaling, and 3-10x faster artifact and container-layer caching. Incremental builds run off full disk snapshots, failed jobs can be debugged over SSH with Action-Debugger, and observability lines CPU, memory, disk, and network telemetry up against your job logs. Warm pools on Enterprise start jobs in under 10 seconds. Deployment is either WarpBuild's managed cloud or BYOC — runners inside your own AWS, GCP, or Azure VPC at $0.002/min for Linux and Windows with caching included, static IPs for allowlisting, and code that never leaves your perimeter. Region-specific infrastructure on Enterprise plans pins CI data to a region you pick and wipes out cloud ingress and egress costs (excluding macOS). Everything is metered per minute, and caching, snapshots, and networking are separate line items on top. This is for teams where the CI queue, not the keyboard, has become the constraint — a pressure that sharpens as coding agents fan out more branches and more pipeline load. GitHub-only, ephemeral per-job runners, and a real per-minute bill mean it's a poor fit for non-GitHub stacks or tiny, sporadic workloads.
Behind the Verdict
We'd reach for WarpBuild the moment CI queue time, not developer skill, is what's slowing releases. The one-line workflow change is genuinely low risk: point your jobs at WarpBuild runners, watch a couple of builds, decide. Teams report the kind of movement that justifies the switch — a roughly 25-minute run down to about 9, a 30-minute iOS build down to 8. Where it actually earns its keep is caching and incremental builds, not just faster CPUs. Full disk snapshots mean each build starts from a warm state, and 3-10x caching on artifacts and container layers is the thing that compounds on monorepos. If your builds are Docker-heavy, the remote builders (16 to 192 vCPU, shared profiles, no hard concurrency limit) are the feature to test first. The bill is where you have to think. Per-minute runner rates are low, but caching, snapshots, and networking sit on top as separate line items. High-volume teams win on economics; a project that runs a handful of tiny jobs a week may pay more than the flat GitHub minutes already bundled into its plan. Pair it with BuildJet gone as of March 31, 2026 and WarpBuild is the obvious migration target for anyone displaced. BYOC is the sleeper option. At $0.002/min for Linux and Windows in your own AWS, GCP, or Azure VPC — caching included, static IPs available — it's the cheapest route and the one that keeps code inside your perimeter. If data residency is a hard requirement, region-specific infrastructure pins data to a chosen region and zeroes out ingress/egress (macOS excepted). Where it bites: GitHub only. GitLab, Bitbucket, and Jenkins shops are out of luck, and if you need persistent long-running VMs rather than ephemeral per-job runners, this isn't the tool. SAML SSO is a $250/month add-on, which stings for smaller teams that

Real-world workflow fit
Concrete scenarios for the personas WarpBuild actually fits — and what changes day-one when you adopt it.
Changes the runs-on line to a WarpBuild Linux 16vCPU runner for the main monorepo workflow, keeps the rest of the YAML untouched, and turns on unlimited caching to work around GitHub's 10GB cache limit.
Outcome: Queue time disappears because concurrency is unlimited, and the Turborepo pipeline stops re-downloading dependencies on every job.
Moves the Xcode build from GitHub-hosted macOS runners to WarpBuild's M4 Pro 6vCPU/14GB at $0.08/min.
Outcome: The team's 30-minute iOS build lands around 8 minutes, matching the customer quote WarpBuild publishes, and the Rust iOS/Android packaging step drops from half an hour to about 8 minutes.
Deploys WarpBuild BYOC into the company's own AWS VPC at $0.002/min with static IPs for an allowlist.
Outcome: CI traffic never leaves the company perimeter, builds land in the existing subnet and firewall policy, and the team keeps SOC2 Type II coverage via the trust center.
Use Cases
- Cut CI build times for monorepos using Turborepo or Nx with fast caching and disk snapshots.
- Cut Docker image build times using remote builders up to 192 vCPU with layer caching.
- Replace GitHub-hosted macOS runners with M4 Pro hardware — a 30-minute iOS build to about 8.
- Adopt BYOC so CI data stays inside your own AWS, GCP, or Azure VPC for compliance.
- Scale to thousands of parallel jobs with unlimited concurrency and no queue delays.
- Debug a failing CI job by SSH-ing into the live runner environment.
- Run Android emulators or spin up Kubernetes clusters in CI using nested virtualization.
- Eliminate GitHub's 10GB cache limit with unlimited cache storage.
Limitations
- WarpBuild is a CI runner service for GitHub Actions, not a model provider; GitHub Actions is the only pipeline it targets, so non-GitHub CI platforms aren't supported.
- Pricing is per-minute by runner size and OS, and the 'unlimited' headline refers to capacity and concurrency, not cost: cache storage runs $0.20 per GB-month, snapshot restore $0.04 per job, snapshot storage $0.025 per hour per snapshot, and cache write/restore $0.0001 per operation.
- BYOC at $0.002/min (Linux/Windows) requires managing your own AWS, GCP, or Azure infrastructure, and static IPs are available with BYOC deployments only.
- Enterprise adds dedicated cloud, custom AMIs, contractual 99.9% uptime SLA and 24/7 support.

- →From GitHub-hosted runners: switch the runs-on target in your workflow file; the same packages are pre-installed so existing actions run unchanged.
- →From BuildJet: BuildJet ceased operations March 31, 2026; move workflows to WarpBuild runners and reuse disk snapshots and unlimited concurrency as the replacement for lost capacity.
- →From actions-runner-controller on Kubernetes: WarpBuild Enterprise claims a guaranteed 40% infra cost saving over ARC, including warm pools with under 10s cold start.
- →From self-hosted runners: replace node maintenance with managed or BYOC runners plus Tailscale networking and static IPs for allowlisting.
- →From GitHub Actions cache: swap actions/cache for WarpBuild's drop-in caching to lift the 10GB cache ceiling.
- ↗To GitHub-hosted runners: revert the runs-on line; nothing else depends on WarpBuild.
- ↗To self-hosted actions-runner-controller: if you need fully custom AMIs or persistent VMs below Enterprise, ARC on your own Kubernetes is the direct path.
- ↗To a managed Kubernetes CI stack: teams that outgrow GitHub Actions entirely move to a platform like GitLab CI or CircleCI, which WarpBuild does not host.
- ↗To a persistent-VM provider: WarpBuild's runners are ephemeral per job, so long-running services need a different CI or VM host.
