Vincosha vs Portkey

The cleanest way to see the difference is to ask what each product sits in front of. A gateway sits in front of the *model*: every inference request passes through it, and that vantage point makes it excellent at routing, caching, rate limiting and cost attribution. Vincosha sits in front of the *artifacts* — the skills, rule files, hooks and MCP connectors an agent loads before it ever makes a request.

That distinction decides which attacks each product can see. A malicious hook that reads `~/.aws/credentials` and posts them to an attacker's endpoint never touches a model gateway, because it never makes an inference call. A poisoned MCP tool description is read by the model as instruction, but it arrives through the host's connection to the server, not through the completion path. A skill that quietly tells an agent to skip a security review is invisible to anything watching prompts and responses. These are the incidents that make a CISO care, and a gateway is architecturally in the wrong place to observe them.

The corollary is fair in the other direction. Vincosha does not route model traffic, does not do provider failover, and is not a caching layer. If you are building an application that calls four providers and needs one API in front of them, we are not that, and a gateway is the right purchase.

For teams that need both — increasingly common — they compose rather than compete. The gateway governs the request path; Vincosha governs what shaped the request in the first place, and Vincosha Ledger attributes cost per session and per asset version so spend can be traced back to the artifact that caused it rather than only to the model that billed for it.
