The Verdict
LinearB is built for engineering managers and vp engineering, with a focus on cycle-time-metrics and dora-metrics. Spacelift targets platform teams and devops engineers and leads with iac-orchestration and policy-engine.
Pricing is close: Spacelift starts at $35/mo versus $39/mo for LinearB — not a deciding factor on its own.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, LinearB offers broader built-in capabilities (7 features vs 6), while Spacelift takes a more focused approach — which can mean a simpler, faster onboarding experience.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
