Frequently asked

Common questions, direct answers.

Can I self-host Semlify? +

On Enterprise only. We ship a Docker Compose bundle with Postgres, Neo4j and the API for customers with strict data-residency requirements. Get in touch to see the deployment guide.

What happens at the concept ceiling? +

We surface a soft block at 100% — the editor stays read-write, but creating new concepts shows an inline upgrade prompt. Existing data stays intact. No silent failures.

Do you offer a startup discount? +

Yes — 50% off the Team plan for two years for companies under $5M ARR or 10 employees. Apply via hello@semlify.com with a one-line description of what you're building.

How do you handle GDPR? +

Semlify is hosted in EU regions for European customers (Pro and above). We sign DPAs, maintain a public sub-processors list, and our Standard Contractual Clauses cover non-EU data flows. See /security for the full posture.

What's covered by the SLA? +

Team: 99.5% monthly uptime, credit on next invoice up to 5%. Business: 99.9%, up to 10%. Enterprise: 99.95% (negotiable higher), up to 20% or as contracted. Full terms at /legal/sla.

Can I switch tiers? +

Up at any time, prorated to the current billing cycle. Down at the end of the cycle, with a usage check — if you're above the lower tier's limits, the UI walks you through what to archive first.
