6 Blacksmith Alternatives for GitHub Actions Ranked

DEV Community

Blacksmith alternatives for GitHub Actions, priced and ranked

The Blacksmith alternatives GitHub Actions teams shortlist are the six other vendors that answer a runs-on label, and they are ranked here by the Linux rate each one published on 2026-09-20 at 2 vCPU. Blacksmith itself sits mid-table at $0.004 for Ubuntu x64 and $0.0025 for ARM, so the question is never only price: it is whether you are leaving for the rate, for a billing model Blacksmith does not publish, or for an operating system it charges a premium on. The same 10,000 Linux minutes at 2 vCPU on each vendor, at the rates published on 2026-09-20, with monthly plan fees inside the bar. Blacksmith x64 lands at $28. GitHub-hosted Team is $42, the $60 list price less the $18 of included usage the Team plan carries. Blacksmith is a genuinely good product and the honest starting point is what it does well. Its pitch, in its own words rather than any benchmark run here, is a high single-core clock on its own metal: the buy when one compile or bundle step is your critical path. It includes 3,000 free minutes a month on every plan card, the most generous standing allowance here. Its ARM card at $0.0025 undercuts every other ARM rate here except Namespace at $0.002, and buys 6 GB at 2 vCPU: Blacksmith publishes arm64 at 3 GB per vCPU, so there is no 8 GB ARM card. The three reasons teams look past it are specific. Ubuntu x64 at $0.004 a minute is mid-table now rather than cheap. Docker layer caching and sticky disks are add-ons at $0.50 per GB per month rather than included, so the effective rate for a Docker-heavy pipeline is above the card. And billing granularity is published nowhere, on the pricing page or in the docs, which is the row that decides a wide matrix of short jobs. The ranking criterion below is the published Linux x64 rate at 2 vCPU for a private repository, read on 2026-09-20, with the memory that rate buys next to it. Every alternative here is a runs-on label change, so the cost of getting this wrong is a revert commit. Every alternative, ranked by published Linux rate A shortlist, not the field: Blacksmith itself and the four its users move to. Ubicloud for the rate, Namespace for cores per dollar, Latchkey for re-run waste, Depot for a Docker cache included rather than billed per GB. WarpBuild and RunsOn are in the next table, and all eight are priced side by side in the roundup. Against each vendor's cheapest card, Blacksmith ARM at $0.0025 is joint third here and its x64 at $0.004 fourth. Vendor Linux, 2 vCPU Linux, 4 vCPU Free tier Billing granularity Best for Ubicloud $0.0012 standard, $0.0020 premium (8 GB) $0.0025 standard, $0.0040 premium 1,250 min/month Not published Leaving Blacksmith purely on rate Namespace $0.002 prepaid at 4 GB, $0.004 at 8 GB $0.004 prepaid at 8 GB 30-day trial only Unit minutes, prepaid or overage Leaving for twice the cores at 8 GB Latchkey $0.0025 (8 GB) $0.005 (16 GB) 2,000 to 6,000 min/month Per minute Leaving because re-runs are a real cost Blacksmith $0.0025 ARM, $0.004 Ubuntu x64 $0.005 ARM, $0.008 Ubuntu x64 3,000 min/month Not published Staying: a compile-bound critical path Depot $0.006 (8 GB) $0.012 (16 GB) 2,000 min on the $20/mo plan Tracked per second, billed monthly in whole minutes Leaving for Docker builds and a big cache What each alternative has that Blacksmith does not The rate is one column of eleven. These are the rest, written against Blacksmith, with the full eight-vendor matrix in GitHub Actions runner alternatives. Vendor Against Blacksmith on rate What it adds What it gives up Ubicloud 70% under x64, 52% under ARM 1,250 free min/mo and 30 GB of cache included rather than metered Windows, macOS and any ARM card at all; Linux x64 only, to 16 vCPU Namespace Level at 8 GB, 50% under at 4 GB Twice the cores at the same 8 GB and the same rate, and remote Docker builders Any standing free allowance; cache is billed at $0.0048/GB-day WarpBuild Level managed, 50% under on BYOC Runners executing inside your own AWS, GCP or Azure account, add-ons free Capacity p...
