Cloudflare AI Gateway vs Sun: AI endpoint control facts side by side
Short answer
Cloudflare AI Gateway describes 1 of the four product control types on the pages we read and Sun describes 0; they differ on on-device control and AI or MCP gateway. On decisions, Cloudflare AI Gateway does not describe tool-call decisions on the pages we read and Sun decides on a tool call before it runs. We do not score either; the right choice depends on the AI tools people use, your devices, your current stack and whether you block or guide.

What are the facts, side by side?

| Positioning | A gateway for AI applications: Cloudflare's documentation describes it as a way to observe and control AI apps, with analytics on requests, tokens and cost, logging, caching, rate limiting, request retry and model fallback across providers including Workers AI, Anthropic, Google Gemini, OpenAI and Replicate. It governs apps you build, not employees' devices. | AI agent security that says it sits in the path of every AI agent across workstations, cloud and SaaS, with three capabilities: discovery, posture management that learns each agent's purpose, and runtime checks of every tool call, connection and resource draw against that purpose before it executes. |
| How it reaches devices | Routed in front of model providers from your own applications; Cloudflare says it takes one line of code to start.

Choose Cloudflare AI Gateway if
- You build your own AI apps and want one place to log and control their model calls
- You already use Cloudflare and want AI traffic to pass through it
Choose Sun if
- You want each agent action checked against that agent's purpose
Which limits should you check?
Cloudflare AI Gateway
- It is an application gateway: it does not see employees' AI tools, coding agents or devices.
- Content controls such as blocking prompts are not described on the page we read, and plan prices are not on it.
Sun
- Sun's site is a single marketing page, so most details are not described.
- How it reaches devices is not described, and no price is published.
