A Sovereign Portkey Alternative
Portkey is a complete LLM gateway platform: routing, guardrails, observability, prompts. The Scrydon AI Gateway is narrower and deeper — every call runs as a person, inside your perimeter, under one policy that also governs the tools your agents call.
Portkey bundles most of what a team wants from a gateway — a unified API across hundreds of providers, virtual keys and budgets, guardrails, caching, prompt management and detailed observability — as a hosted platform with a self-hosted option. The Scrydon AI Gateway asks a different first question: who is this, what may they reach, and can we prove what their agent did next, wherever our production runs. It stands alone and can be deployed on its own.

The Scrydon AI Gateway is a sovereign alternative to Portkey: a single governed endpoint that speaks the standard model APIs so existing tools reach any model unchanged, where every call runs under the caller's own federated identity rather than a virtual key, against a clearance-gated model allowlist, with data loss prevention, a spend cap and an immutable audit trail. It shares one policy and one audit chain with governed tool calls and sandbox egress, and runs air-gapped, on-premises or on a European sovereign cloud.
Portkey is one of the most complete products in the LLM gateway category: an open-source gateway and a hosted platform around it, with a unified API across hundreds of providers, virtual keys and budgets, configurable guardrails, semantic caching, routing with fallbacks, prompt management and a strong observability layer. For a product team building on models it is a lot of value in one place. Its limits are the category's: attribution stops at a virtual key or the metadata a caller chooses to send; governance ends at the model call, while an agent's day is mostly tool calls against systems that hold your data; and the control plane is the vendor's unless you take on the self-hosted edition. The Scrydon AI Gateway keeps the developer experience — the standard APIs, any model, unchanged tools — and moves the control point into your perimeter: a gateway key minted against a named person in your identity provider, the allowlist following that person's clearance, and the same identity governing the tools the agent calls over MCP and the network its sandbox may reach.
Runs as a Person, Not a Key
Every call resolves through your identity provider to the human who made it, with their delegated grants — the basis for per-developer cost, clearance-gated models and revocation on the next turn.
Governance Past the Model Call
One policy and one audit chain across the model call, the tools the agent calls over MCP, and the egress of the sandbox those tools run in.
Sovereign by Deployment
Air-gapped, on-premises or a European sovereign cloud, with open-weight models on your own hardware behind the same endpoint.

What Portkey bundles, and what the AI Gateway does with the same request
Portkey's strength is completeness: a unified API across hundreds of providers, virtual keys with budgets, configurable guardrails, caching, routing with fallbacks, prompt management and detailed observability, in one hosted platform with a self-hosted gateway for those who need it. The Scrydon AI Gateway is narrower on purpose and changes what happens behind the address: the call runs as a named person from your identity provider, the model allowlist follows that person's clearance, data loss prevention screens what leaves, and the audit record settles before the stream finishes. The vendor key is never issued to anyone.
The standard APIs, unchanged tools — Both speak the APIs your tools already speak, so coding agents and applications on a standard completions API run through either without modification.
Identity from your provider, not a key or a header — Portkey attributes a call to a virtual key and whatever metadata the caller sends. The AI Gateway mints keys against a named person in your identity provider and refuses a request that tries to name a tenant.
Policy at dispatch, on every call — A clearance-gated allowlist decides which models this person may reach; data loss prevention and moderation run inline; the turn is metered against the organisation's cap before the answer lands.
The same chain for tools and egress — When the agent goes on to call a system over MCP or run code in a sandbox, the same credential model, policy snapshot and audit trail apply — a model-only gateway is not in that path.
When the feature list is long and the auditor's list is short
Portkey is a fair choice for a product team that wants the most gateway in one place and is comfortable with a hosted control plane. The gap opens when the organisation is a public body or a regulated enterprise and the questions come from an auditor rather than a product manager: which person made this call, what did their agent do afterwards against systems the gateway never saw, and where exactly do the prompts and the keys live. A virtual key and a metadata header cannot answer the first; no model-only gateway can answer the second; and a hosted control plane makes the third a contract clause rather than an architecture. The Scrydon AI Gateway is built for those questions: every call attributable to a person, one policy and one audit chain across the model call, the tools the agent calls and the sandbox it runs in, deployed where your production runs — and deployable on its own before anything else is.
Scrydon AI Gateway vs Portkey
Both put every model behind one address, both meter spend, both apply guardrails. The difference is who the call runs as, where the control plane lives, and how far the governance reaches once the model has answered.
| Capability | Scrydon | Portkey |
|---|---|---|
| Who the call runs as | The person, resolved through your identity provider, with their own delegated grants | A virtual key, plus caller-supplied metadata for attribution |
| Model calls governed | Clearance-gated allowlist, DLP, moderation, cap and immutable audit on every call | Model access per key, budgets and rate limits, configurable guardrails, logging |
| Tool calls governed | Same identity, policy and audit chain as the model call | Partly, where it also fronts a tool protocol; not the caller's delegated grants |
| Network egress from the sandbox | Enforced outside the workload, which cannot reconfigure it | Out of scope |
| Where the vendor key lives | On the platform; never issued to a developer | In the gateway's vault, hosted or self-hosted |
| Cost attribution | Per person, per team or unit, and per turn, by model, capability and workflow, with an on-pace projection and a cap | Per key, workspace and metadata, with budgets and detailed analytics |
| Deployment | Sovereign — air-gapped, on-premises or European cloud | Hosted platform; self-hosted gateway on higher tiers |
| Pricing model | Fixed monthly fee for the cluster that carries your people, excluding hosting | Open-source gateway; hosted plans by usage, enterprise by agreement |
A category comparison, written to orient: Portkey is a strong, complete product and we would not pretend otherwise. Portkey is a trademark of its owners; capabilities evolve — verify current details with the vendor.
