AnchorGate + Portkey
Portkey ships your AI product. AnchorGate faces your auditor.
Portkey is a full LLMOps platform — gateway, observability, prompt management, guardrails — built to help teams get AI to production. AnchorGate is one deliberate thing: a self-hosted governance gate for regulated traffic. If you run Portkey and an audit is coming, these compose rather than compete.
How it composes
Compose them, don’t choose
Both sides speak the OpenAI API, so the gate chains with Portkey the same way it chains with any gateway: AnchorGate governs first, Portkey routes and observes after — or the reverse. Each request crosses policy once and lands on the signed ledger either way.
# apps → AnchorGate (governs) → Portkey (routes, observes) → providers
export OPENAI_BASE_URL=http://anchorproxy:8080/v1
# anchorgate.yaml — Portkey is just an upstream
upstream: https://your-portkey-gateway/v1
The difference in kind
Two jobs, done by the layer built for each
These rows compare purposes, not feature checklists — their features ship weekly and ours do too, and a stale checklist helps nobody.
Portkey
A platform: unified model access, observability, prompt management, and guardrails — the tooling for building and operating AI products.
AnchorGate
A gate: policy enforcement, redaction, MCP security, and evidence — the tooling for governing AI traffic and proving what happened.
Portkey
Optimized for the product team’s loop — iterate on prompts, watch latency and cost, ship.
AnchorGate
Optimized for the GRC team’s loop — enforce the policy, quarantine the risk, export the Trust Packet.
Portkey
Operates as a managed platform, with hybrid options and an open-source gateway at its core.
AnchorGate
Self-hosted only, 100% open source, no hosted offering — raw prompts and evidence never leave your VPC, because there is no AnchorGate cloud.
Portkey
Observability: rich logs, traces, and analytics dashboards for engineers.
AnchorGate
Evidence: ECDSA-signed, append-only decision records graded L1–L5, verifiable offline without trusting the dashboard — or the vendor.

The honest split
Where each one earns its place
Use Portkey for
- A managed platform experience across many providers
- Prompt management and iteration workflows
- Product observability — latency, cost, usage analytics
- Operational guardrails within your LLMOps flow
Add AnchorGate for
- A self-hosted enforcement point inside your own boundary
- Deterministic, fail-closed policy with human-approved bundles
- Signed decision evidence mapped to EU AI Act, ISO 42001, SOC 2
- Deny-by-default MCP tool-call security with TBAC tokens
FAQ
Composing with Portkey
- Is AnchorGate a Portkey alternative?
- Not honestly, no. If you need prompt management, provider breadth, and product observability, Portkey is built for that and AnchorGate isn’t. If you need self-hosted enforcement and cryptographically verifiable evidence for a regulator, that’s the job AnchorGate was built for. Teams with both needs run both — the chain is one base-URL change.
- Can AnchorGate sit behind Portkey rather than in front?
- Yes. AnchorProxy speaks OpenAI-compatible on both sides, so Portkey can forward through AnchorGate on its way upstream. Front position means policy and redaction run before anything else touches the request; behind means Portkey’s routing decisions come first. Pick by which layer you want closest to your apps.
- We already use Portkey’s guardrails — what would the gate add?
- Whatever your auditor asks for that a product platform doesn’t produce: fail-closed deterministic enforcement inside your own network boundary, and decision records that are signed, append-only, and verifiable offline. If no auditor is coming, you may genuinely not need it — we’d rather say that than manufacture urgency.
Built for the meeting Portkey isn’t in.
When the question changes from “is the product fast and cheap?” to “prove what your agents did” — that’s the gate’s job. Self-hosted, open source, composes with what you run.
