SIFTGATE OSS

SiftGate

A self-hosted AI gateway for apps, coding agents, MCP tools, provider keys, routing, budgets, cache, and evidence.

SiftGate is an MIT open-source data plane. It keeps provider keys, gateway keys, routing policy, budgets, cache, audit, and dashboard evidence inside your infrastructure, with metadata-only operations by default.

OSS DATA PLANE

Not just a proxy. A governed AI traffic layer.

SiftGate puts model routing, provider credential pools, agent profiles, MCP, budgets, and dashboard evidence into one self-hosted runtime.

Explainable routing

Records selected, skipped, fallback, budget, and compatibility evidence so every model choice is traceable.

Provider key isolation

Clients use Gateway API keys while upstream provider keys stay in SiftGate nodes, env vars, or secret references.

Coding agent gateway

Gives Codex, Claude Code, Cursor, Cline, Roo Code, Continue, and similar tools one governed ingress.

MCP tool governance

Proxies MCP tool traffic behind Gateway API keys, namespace allow-lists, and rate limits.

Cost and cache evidence

Tracks tokens, estimated cost, provider-cache savings, budget scopes, and chargeback metadata.

Metadata-only by default

Does not store prompts, responses, raw headers, provider keys, tool payloads, media, source code, or diffs by default.

REQUEST PATH

Govern the request before it leaves your infrastructure

Clients never touch upstream provider keys directly. SiftGate applies gateway keys, policy, budget, compatibility, routing, and credential-pool decisions before forwarding.

Model Providers
Who can call which model?

Gateway API keys, workspaces, teams, policy namespaces, endpoint/model/node limits, rate limits, and budgets.

Where should traffic go now?

Compatibility filters, tiered routing, fallback chains, circuit state, cache-aware cost, and route explanation.

Which upstream key is working?

Credential pools support least-in-flight, weighted round-robin, sticky affinity, cooldown, and retry failover.

What evidence remains after a request?

Metadata-only call logs, route traces, provider health, cache savings, cost estimates, session timelines, and audit.

PUBLIC EVIDENCE

Evidence lives in the open-source repo

Provider smoke matrices, benchmark reports, and agent+MCP demos come from the OSS documentation assets for self-hosted evaluation.

DASHBOARD

Open-source dashboard screenshots

These captures are from the SiftGate open-source dashboard: local setup, configuration, observability, and cost evidence live in one operating surface.

01

Gateway Overview

From setup to health, guardrails, cost metrics, and cache hits, one screen shows the open-source data plane in motion.

Provider Catalog

Maintains provider metadata, pricing sources, active profiles, and custom providers so node setup is evidence-backed.

Usage Analytics

Tracks calls, tokens, spend, cache impact, and provider usage, turning AI traffic into operational data.
