Use Case Recommendations
Best for: ContentMod
ContentMod is a text and image moderation API for teams that have suddenly acquired user-generated content and no policy machinery to handle it. You add the SDK, post text or images, and get back a moderation verdict — across more than 50 languages for text, and with visual classification for images — either synchronously or delivered to a callback URL as a webhook, which is the shape most upload pipelines actually need. What lifts it above a bare classifier is the human layer around it: review queues hold flagged content for manual or automated adjudication instead of forcing a binary allow/deny at request time, and wordlists let you push a list of banned terms specific to your product, community or client rather than relying only on the model's general notion of harm. A playground lets you paste real inputs and see the verdicts before writing any code, an analytics view reports moderation volume and outcomes over time, and integrations connect it to existing tools. There is a Discord bot for communities that live there, and free standalone text and image analyzers for one-off checks. Pricing is a token model where a text moderation costs one token and an image costs three, with a stated per-token overage rate on each plan, so the cost of a viral upload day is calculable in advance.
Ideal use cases:
- •Teams or individuals who need text and image moderation behind one api
- •Teams or individuals who need review queues for manual or automated adjudication
- •Teams or individuals who need custom banned-word lists per project
- •Teams or individuals who need webhook callbacks for asynchronous pipelines
- •Anyone focused on api workflows
- •Anyone focused on moderation workflows
Best for: Nen
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.
Ideal use cases:
- •Teams or individuals who need payload stays ciphertext past tls termination — logs, cdn and proxies see base64
- •Teams or individuals who need ml-kem-768 (fips 203) post-quantum key exchange with chacha20-poly1305
- •Teams or individuals who need drop-in nenfetch client and withnen server wrapper, about ten lines total
- •Teams or individuals who need mandatory per-request hmac and replay protection; encrypted sse streaming
- •Anyone focused on encryption workflows
- •Anyone focused on post-quantum workflows
