Feature matrix

	API Meter (beta)	Moesif	Treblle
Per-customer usage	Yes: tag responses with `X-MSA-Customer-Id` / `X-MSA-Plan`, or API keys are hashed into a customer ID. Per customer, endpoint and plan.	Yes: `identifyUser` and `identifyCompany` hooks in the SDK (Moesif Node.js docs, fetched Oct 14, 2026).	"API Customer info" listed on Core (treblle.com/pricing, fetched Oct 14, 2026); SDK `setMetadata` for user-id/plan (Treblle Node SDK docs, fetched Oct 14, 2026).
Setup	No SDK. Point clients at your API Meter proxy URL and verify your origin (one well-known file). Optional two response headers.	Server SDK per framework or a gateway plugin (Express, FastAPI, Cloudflare Workers, Kong, NGINX and more), or OpenTelemetry (Moesif server integrations, fetched Oct 14, 2026).	SDK middleware per framework with an SDK token and API key in env vars (Treblle Node SDK docs, fetched Oct 14, 2026).
Adds a network hop?	Yes, traffic flows through a Cloudflare Worker (about 3.4 ms median in our own test from one location).	No for SDKs (logs sent from your server).	No (SDK sends data from your server).
Data captured	Metadata only: method, normalized endpoint, status, latency, bytes, country, customer and plan. No bodies, headers, query strings or IPs (privacy).	Request/response bodies logged by default (`logBody: true`) (Moesif Node.js docs, fetched Oct 14, 2026).	Request/response bodies and headers, with sensitive keywords masked by default (Treblle Node SDK docs, fetched Oct 14, 2026).
Retention	7 days during the beta.	1 year on all paid plans (moesif.com/price, fetched Oct 14, 2026).	30 days on Core (treblle.com/pricing, fetched Oct 14, 2026).
Free tier	Free to 250K requests/month planned; during the beta capture is capped at ~1,000 events/day across all APIs.	Free: 50K events/month, 1 team member (Moesif AWS Marketplace listing, fetched Oct 14, 2026).	No free tier on the pricing page (treblle.com/pricing, fetched Oct 14, 2026). Billing docs still list Free (250K requests, 7 days) (Treblle billing docs, fetched Oct 14, 2026): unverified whether it's still offered.
Entry paid price	Indie CA$19/month with 2M included, CA$3 per extra million: not available yet (checkout coming).	Growth from US$60/mo (300K events); US$165 (1M), US$790 (5M) (Moesif AWS Marketplace listing, fetched Oct 14, 2026); +US$75/mo per extra team member (moesif.com/price, fetched Oct 14, 2026).	Core US$233/mo billed yearly: 5 APIs, 5M requests/month, unlimited team members (treblle.com/pricing, fetched Oct 14, 2026).
Billing	CAD, monthly (planned).	USD; overage pay-as-you-go, invoiced monthly (moesif.com/price, fetched Oct 14, 2026).	USD; Core is credit card only (treblle.com/pricing, fetched Oct 14, 2026).
Beyond analytics	No. Usage analytics only.	Usage-based billing, quotas, developer portal (Moesif AWS Marketplace listing, fetched Oct 14, 2026).	Docs, testing, observability, alerts (treblle.com/pricing, fetched Oct 14, 2026).

Setup effort, honestly

API Meter: change one base URL, then drop a verification file on your origin. Works with any language because it's a reverse proxy. See integration guide and Cloudflare setup without an SDK.
Moesif: install the SDK or gateway plugin for your stack, add your application ID, then write identifyUser/identifyCompany functions to attribute calls (Moesif Node.js docs, fetched Oct 14, 2026).
Treblle: install the SDK (e.g. npm install treblle), add SDK token and API key, add middleware (Treblle Node SDK docs, fetched Oct 14, 2026). Their Node v3 SDK dropped Cloudflare Workers support (stay on 2.x for now) per the same page.

Where API Meter is weaker

It's a beta: no SLA, and event capture is capped at about 1,000 events/day across all APIs for now (traffic is always forwarded).
No SDK: setup is proxy-only, which adds a hop and means you route traffic through Cloudflare.
No paid plan yet, so no higher limits you can buy today. Retention is 7 days.
No body logging, alerts, docs generation or billing features. Moesif and Treblle do much more.

Pick API Meter if you want per-customer counts with no SDK and no yearly contract and can live with beta limits. Pick Moesif for billing and long retention, or Treblle for a broader API platform.
