A/B Testing / Experimentation
Buildkite and Depot bill differently, which matters more than feature parity here — Buildkite offers a free tier, paid from $2.50, while Depot sells a subscription from $500/mo with a free tier. Buildkite is self-hosted CI/CD runner with agent-based pipelines on your own infrastructure. Depot is remote Docker build acceleration service for CI image builds. Pick Buildkite when the job is conversion optimization and you accept low lock-in; pick Depot when it is conversion optimization and you accept low lock-in. The data we have shows Buildkite at mostly transparent pricing and docs with a polished developer experience, and Depot at fully public pricing and documentation with a polished developer experience. The honest trade-off: neither is universal — Buildkite is a poor fit for internal projects, and Depot is a poor fit for internal projects. Match the pricing model and lock-in level to how your team actually works, not the feature list.
Quick take
Buildkite is for self-hosted CI/CD runner; Depot is for remote Docker build acceleration service; decide based on pricing model fit.

Choose Buildkite if a free tier with paid upgrade from $2.50 is the right shape and the work maps to self-hosted CI/CD runner with agent-based pipelines on your own infrastructure.
Not for: Internal projects
Choose Depot if you need public pricing and docs before committing and the work lines up with remote Docker build acceleration service for CI image builds.

Buildkite starts at $2.50 on a freemium model; Depot starts at $500/mo on a subscription model. That makes the sticker comparison depend on usage — a low entry price can get expensive once volume ramps, so price at your actual workload.
Migration in either direction is relatively cheap — both Buildkite and Depot are rated low lock-in, so your configuration and data should port without a rewrite. The realistic cost is team re-training and pipeline QA, not the tools themselves.
Both Buildkite and Depot rate the same on developer experience (5/5). The decision on DX then comes down to taste — which CLI, UI, or workflow matches your team's habits. A short side-by-side trial is the quickest way to tell.
Yes — Depot is a reasonable alternative to Buildkite for conversion optimization. The practical differences are freemium-vs-subscription billing and low-vs-low lock-in. If those fit your constraints better, treat Depot as a credible swap.
