Nen Pricing 2026
Complete pricing guide for Nen — plans, costs, and free options.
💰 Nen Pricing Overview
Nen uses a freemium pricing model. Free tier available with optional paid upgrades. Current pricing: Open Source is $0 forever and includes the complete SDK with no limits: @withnen/client and @withnen/server, ML-KEM-768 key exchange with ChaCha20-Poly1305, mandatory per-request HMAC, encrypted SSE streaming via nenStream, in-memory and Redis session stores, and the public protocol spec and threat model. Cloud is $79/mo and adds a live session and key-rotation dashboard, error-rate and latency monitoring, searchable audit logs, Upstash and edge session backends and email support, with a free trial. Enterprise is custom-priced and adds exportable compliance evidence (ML-KEM-768 per endpoint, timestamped), HSM/KMS integration, SAML/SSO and dedicated support with an SLA. The paid tiers buy visibility and exportable audit evidence rather than the encryption itself, which is free at every tier.. Nen is a popular security & privacy tool known for end-to-end encrypted api payloads using post-quantum ml-kem-768, so logs, cdns and proxies see only ciphertext after tls terminates. You can get started with Nen for free and upgrade to a paid plan as your needs grow.

Is Nen Worth It?
Nen is a freemium security & privacy tool that offers 5 key features including Payload stays ciphertext past TLS termination — logs, CDN and proxies see base64, ML-KEM-768 (FIPS 203) post-quantum key exchange with ChaCha20-Poly1305, Drop-in nenFetch client and withNen server wrapper, about ten lines total. Nen addresses a gap that is not a flaw in TLS so much as the place TLS stops. HTTPS protects a request in transit and does it well, but the moment TLS terminates — at the load balancer, the CDN edge, the serverless runtime — the JSON body sits in plaintext across logs, databases, proxies and every third-party hop. Nen keeps the payload itself encrypted end to end, so the trust boundary moves inward past all of that to the specific code that genuinely needs to read the data. The integration is deliberately small: swap fetch for nenFetch on the client, wrap the route handler with withNen on the server, and the handshake, key rotation, per-request HMAC and replay protection happen underneath, roughly ten lines start to finish. The cryptography is post-quantum by default — ML-KEM-768 key exchange under FIPS 203 with ChaCha20-Poly1305 for the payload — which matters specifically for harvest-now-decrypt-later exposure, since payloads that come to rest as ciphertext in a queue or a database stay protected. Encrypted server-sent-event streaming is supported, along with in-memory, Redis and edge session stores. The site is unusually careful about what it does not claim: it states plainly that the two Nen endpoints necessarily hold plaintext, publishes a threat model and protocol spec, and even links a page arguing that if your only concern is the public transit leg, PQ-TLS already covers you. The SDK is open source with no limits.
✅ Nen is a good choice if you need:
- •Payload stays ciphertext past TLS termination — logs, CDN and proxies see base64
- •ML-KEM-768 (FIPS 203) post-quantum key exchange with ChaCha20-Poly1305
- •Drop-in nenFetch client and withNen server wrapper, about ten lines total
- •Mandatory per-request HMAC and replay protection; encrypted SSE streaming
- •Open-source SDK with a published protocol spec and threat model
💡 Value Assessment
