Frequently asked
- Can I start for free?
- Yes. The Hobby tier is permanently free — no credit card needed. You get access to the full CLI, SDK, and Studio for up to 3 workflows.
- What counts as a workflow run?
- Each time a workflow executes from trigger to completion counts as one run. Failed runs count too. You can inspect every run in Studio.
- Can I use KB Labs on-premise?
- Self-hosted deployment is available on the Enterprise plan. We support Docker Compose and Kubernetes. Contact us to discuss your infrastructure requirements.
- Is there a trial for Pro?
- Pro is not yet available — join the waitlist and we'll give you early access with an extended trial period when we launch.
- How does billing work for teams?
- Pro is priced per seat. Each member of your organization who accesses the platform counts as one seat. Admins can manage seats in the billing dashboard.
- What happens if I exceed my run limit?
- On Hobby, new runs are queued until the next billing cycle. On Pro, you'll receive an alert and can upgrade or purchase additional run packs.
