This post provides a detailed comparison between Blacksmith and WarpBuild to help you make an informed decision. ## Feature Comparison | Feature | Blacksmith | WarpBuild | WarpBuild Advantage | | ------------------------------- | ------------------------------------------------------ | ------------------------------------------------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **CPUs** | Server class (AMD EPYC, ARM Ampere) | x86-64 (Desktop Class Ryzen 7950X3D), arm64 (Graviton 4) | arm64: 40% more powerful but ~20% more expensive than Blacksmith; x86-64: same performance; Better networking, more disk options | | **Architecture** | x86-64, arm64 | x86-64, arm64 | arm64: 40% more powerful but ~20% more expensive than Blacksmith; x86-64: same performance; Better networking, more disk options | | **Concurrency** | Unlimited | Unlimited | | | **OS Support** | Ubuntu 22.04, 24.04 only | Ubuntu 22.04, 24.04, MacOS 13/14/15 with M4 Pro, Windows Server 2022 | Latest Linux, MacOS, Windows, custom images through app | | **Caching** | 25GB per repo | Unlimited; 7-day retention; Scales to 100+ jobs with no throttling | Unlimited storage, better scaling, container layer caching | | **Infrastructure** | EU and US | Cloud (EU), BYOC (AWS, GCP, Azure any region) | Multiple providers/regions, reduced data transfer costs | | **Sticky Disks** | Available | Not available | Cache stored on sticky disks is instantly available to runners, but concurrency is limited | | **Remote Docker Builder** | Only x86-64 | x86-64 and arm64 multi-arch builds | Multi arch support for fast, native builds. | | **SSO support** | Not available | SSO supported | SSO supported for Microsoft Entra ID, Google, Okta, Auth0, JumpCloud etc. | | **Static IPs** | Available as paid feature | Available at no cost (BYOC only) | | | **Pricing** | 50% of GitHub cost | x86-64: Same as Blacksmith; arm64: 40% more powerful, 20% more expensive | | | **Snapshots** | Not available | Available | Save and restore runner state for persistence and incremental builds. Provides 10x improvement in build times by eliminating dependency installation time. | | **Bring Your Own Cloud (BYOC)** | Not available | Available | Cloud-hosted control plane with runners in user's cloud account. Provides maximum flexibility, zero management overhead, and is 10x cheaper than Blacksmith. Users can leverage preferential pricing with their cloud providers. | | **Compliance** | SOC2 Type2 | SOC2 Type2 | | | **Global Regions** | Limited to EU and US | Cloud (EU), Support for 29+ regions globally (BYOC) | Minimizes data transfer costs, improves performance, and supports data residency regulations essential for sensitive workloads. | | **Configurable Disks** | Fixed 80-160GB | Configurable sizes, IOPS, and throughput | Optimized for ML/AI workloads, large container builds, monorepos, game and mobile app development. | | **Advanced Dashboard** | Richer dashboard | Rich dashboard | Blacksmith has more insights on metrics like cost saved, and analytics on cache usage. | | **Security** | Bot requires read-write access to code and build logs. | Bot requires minimal permissions and no code or build logs access. | This is crucial for Enterprises and security conscious teams. | ![Blacksmith WarpBuild Cache](/images/blog/blacksmith-warpbuild-comparison-2025-May/blacksmith-warpbuild-cache.png) ![WarpBuild Dashboard](/images/blog/blacksmith-warpbuild-comparison-2025-May/warpbuild-dashboard.png) ![WarpBuild Analytics](/images/blog/blacksmith-warpbuild-comparison-2025-May/warpbuild-analytics.png) ## Conclusion Blacksmith provides fast Github Actions runners. WarpBuild provides equally fast x86-64 runners, and even faster arm64 runners. For enterprises, WarpBuild delivers 10x faster builds with SSO, snapshots, multi-arch docker builder cloud. WarpBuild also provides BYOC for improved security and more customization at a fraction of the cost (~5x cheaper compared to Blacksmith). ## Get Started Today WarpBuild is committed to providing you with the tools you need to build faster, smarter, and more cost-effectively.
