Frequently asked questions
Frequently asked questions
How much does QNSP cost?
QNSP starts free forever — 10 GB PQC storage and 50K API calls per month, no credit card. Paid plans run from $149/month (Dev Starter) through $24,999/month (Enterprise Pro). Enterprise Elite and mission-critical tiers (Public Sector, Defense & Space, Critical Infrastructure) are custom-quoted. Fourteen plans cover every scale.
Is the Free tier really free forever?
Yes. The Free tier is free for everyone — individuals, startups, and enterprises — indefinitely. No credit card required. No artificial time limit. You start with 10 GB PQC-encrypted storage, 50K API calls/month, 20 KMS keys, 25 vault secrets, and all SDKs (TypeScript, Python, Go, Rust, JVM/Android).
Are SDKs included on every plan?
Yes. All SDKs are free on every plan including the Free tier — one single-package SDK per language: @cuilabs/qnsp on npm (TypeScript), qnsp on PyPI (Python), github.com/cuilabs/qnsp-public/sdks/go/qnsp (Go), qnsp on crates.io (Rust), and io.cuilabs:qnsp on Maven Central (JVM/Android). Plus @cuilabs/qnsp-browser for browser apps, @cuilabs/qnsp-cli for scripting/CI, and @cuilabs/qnsp-mcp for AI assistants.
How does enterprise pricing work?
Enterprise Standard, Pro, and Elite tiers are subscription-based. Enterprise Elite and mission-critical tiers (Public Sector, Defense & Space, Critical Infrastructure) require a custom contract. Contact qnsp-sales@cuilabs.io to start the conversation.
Can I self-host or air-gap QNSP?
Yes. VPC, private cloud, on-premises, and air-gapped deployments are available on Enterprise Elite, Public Sector, Defense & Space, and Critical Infrastructure tiers. These require a custom deployment agreement.
What is HSM integration?
Enterprise tiers support integration with customer-managed HSMs (Thales Luna, Entrust nShield, AWS CloudHSM, Azure HSM) via PKCS#11. Certification level (FIPS 140-3, etc.) depends on the selected HSM and customer deployment configuration.
