Buildkite is fast — but you manage the agents, servers, and infrastructure. RubyCI gives you the same speed, fully managed, with fixed pricing and zero config.
Buildkite gives you control, but that control comes with real costs — servers to manage, agents to maintain, and infrastructure to scale.
Buildkite requires you to provision, scale, and maintain your own build agents on AWS, GCP, or bare metal. RubyCI is fully managed — we handle everything.
Buildkite charges per user, plus you pay for your own compute (EC2, spot instances, etc.). Factor in DevOps time and the real cost is 3-5x what you think.
Buildkite is BYO everything — you wire up coverage, security, and quality tools yourself. RubyCI includes SimpleCov, RubyCritic, Brakeman, and Bundler Audit out of the box.
Buildkite's per-user price looks reasonable — until you add infrastructure, DevOps time, and scaling costs.
~$400-800/mo
$15/user/mo for Buildkite + $200-600/mo for EC2/compute agents + DevOps engineer time for maintenance and scaling.
$149/mo
Fixed price. Fully managed. No agents to run, no servers to scale, no infrastructure bills. Everything included.
In most cases, yes. RubyCI runners are Ruby-optimized with pre-installed dependencies, so you skip the setup time that even self-hosted agents spend. Combined with automatic test splitting, total pipeline time is comparable or faster.
RubyCI replaces the most common plugins: test splitting, code coverage, security scanning, and artifact management are all built in. For non-CI tasks like deployments, you can keep using Buildkite alongside RubyCI.
Yes. Start with one repo on RubyCI while keeping Buildkite for the rest. Once you're confident, migrate more repos at your own pace. There's no conflict between the two.
RubyCI handles the environment so you don't have to. Ruby versions, system packages, databases, and Redis are all managed automatically. You focus on code, not infrastructure.
Your DevOps team can focus on higher-value work instead of maintaining CI agents. RubyCI eliminates the toil of agent scaling, patching, and monitoring — freeing up engineering time.
Get fully managed Ruby CI without the infrastructure overhead. Fixed pricing, zero config — free to start.
