Arch Gateway Alternatives 2025: Top 10

Updated November 2025

If you’re evaluating Arch Gateway alternatives, this guide maps the landscape like a builder would. First, we clarify what Arch Gateway is—a prompt-aware gateway for LLM traffic and agentic apps—then compare the 10 best alternatives. We place ShareAI first for teams that want one API across many providers, pre-route transparency (price, latency, uptime, availability) before routing, instant failover, and people-powered economics (70% of spend goes to providers).

What Arch Gateway is (and isn’t)

What it is. Arch Gateway (often shortened to “Arch” / archgw) is an AI-aware gateway for agentic apps. It sits at the edge of your stack to apply guardrails, normalize/clarify inputs, route prompts to the right tool or model, and unify access to LLMs—so your app can focus on business logic instead of infrastructure plumbing.

What it isn’t. Arch is a governance-and-routing layer for prompts and agents; it’s not a transparent model marketplace that shows provider price, latency, uptime, availability before you route. That’s where ShareAI shines.

Aggregators vs Gateways vs Agent platforms

• LLM aggregators — One API across many models/providers with pre-route transparency (price, latency, uptime, availability, provider type) and smart routing/failover. Example: ShareAI.
• AI gateways — Edge governance for LLM traffic (keys, policies, rate limits, guardrails) plus observability. You bring your providers. Examples: Arch Gateway, Kong AI Gateway, Portkey.
• Agent/chatbot platforms — Packaged UX (memory/tools/channels) for assistants; closer to product than infra. Example: Orq.

How we evaluated the best Arch Gateway alternatives

• Model breadth & neutrality — proprietary + open; easy switching; no rewrites.
• Latency & resilience — routing policies, timeouts/retries, instant failover.
• Governance & security — key handling, scopes, regional routing, guardrails.
• Observability — logs/traces and cost/latency dashboards.
• Pricing transparency & TCO — compare real costs before you route.
• Developer experience — docs, SDKs, quickstarts; time-to-first-token.
• Community & economics — whether your spend grows supply (incentives for GPU owners).

Top 10 Arch Gateway alternatives

#1 — ShareAI (People-Powered AI API)

What it is. A multi-provider API with a transparent marketplace and smart routing. With one integration, browse a large catalog of models and providers, compare price, latency, uptime, availability, provider type, and route with instant failover.

Why it’s #1 here. If you want provider-agnostic aggregation with pre-route transparency and resilience, ShareAI is the most direct fit. Keep a gateway if you need org-wide policies; add ShareAI for marketplace-guided routing.

• One API → 150+ models across many providers; no rewrites, no lock-in.
• Transparent marketplace: choose by price, latency, uptime, availability, provider type.
• Resilience by default: routing policies + instant failover.
• Fair economics: 70% of spend goes to providers (community or company).

#2 — Kong AI Gateway

What it is. Enterprise AI/LLM gateway—governance, policies/plugins, analytics, and observability for AI traffic at the edge. It’s a control plane rather than a marketplace.

#3 — Portkey

What it is. AI gateway emphasizing guardrails and observability—popular in regulated environments.

#4 — OpenRouter

What it is. Unified API over many models; great for fast experimentation across a wide catalog.

#5 — Eden AI

What it is. Aggregates LLMs plus broader AI capabilities (vision, translation, TTS), with fallbacks/caching and batching.

#6 — LiteLLM

What it is. A lightweight Python SDK + self-hostable proxy that speaks an OpenAI-compatible interface to many providers.

#7 — Unify

What it is. Quality-oriented routing and evaluation to pick better models per prompt.

#8 — Orq AI

What it is. Orchestration/collaboration platform that helps teams move from experiments to production with low-code flows.

#9 — Apigee (with LLMs behind it)

What it is. A mature API management/gateway you can place in front of LLM providers to apply policies, keys, and quotas.

#10 — NGINX

What it is. Use NGINX to build custom routing, token enforcement, and caching for LLM backends if you prefer DIY control.

Arch Gateway vs ShareAI

If you need one API over many providers with transparent pricing/latency/uptime/availability and instant failover, choose ShareAI. If your top requirement is egress governance—centralized credentials, policy enforcement, and prompt-aware routing—Arch Gateway fits that lane. Many teams pair them: gateway for org policy + ShareAI for marketplace routing.

Pricing & TCO: compare real costs (not just unit prices)

Raw $/1K tokens hides the true picture. TCO shifts with retries/fallbacks, latency (affects usage), provider variance, observability storage, and evaluation runs. A transparent marketplace helps you choose routes that balance cost and UX.

TCO ≈ Σ (Base_tokens × Unit_price × (1 + Retry_rate))
      + Observability_storage
      + Evaluation_tokens
      + Egress

• Prototype (~10k tokens/day): Optimize for time-to-first-token (Playground, quickstarts).
• Mid-scale (~2M tokens/day): Marketplace-guided routing/failover can trim 10–20% while improving UX.
• Spiky workloads: Expect higher effective token costs from retries during failover; budget for it.

Migration guide: moving to ShareAI

From Arch Gateway

Keep gateway-level policies where they shine, add ShareAI for marketplace routing + instant failover. Pattern: gateway auth/policy → ShareAI route per model → measure marketplace stats → tighten policies.

From OpenRouter

Map model names, verify prompt parity, then shadow 10% of traffic and ramp 25% → 50% → 100% as latency/error budgets hold. Marketplace data makes provider swaps straightforward.

From LiteLLM

Replace the self-hosted proxy on production routes you don’t want to operate; keep LiteLLM for dev if desired. Compare ops overhead vs. managed routing benefits.

From Unify / Portkey / Orq / Kong

Define feature-parity expectations (analytics, guardrails, orchestration, plugins). Many teams run hybrid: keep specialized features where they’re strongest; use ShareAI for transparent provider choice and failover.

Developer quickstart (copy-paste)

The following use an OpenAI-compatible surface. Replace YOUR_KEY with your ShareAI key — get one at Create API Key. See the API Reference for details.

#!/usr/bin/env bash
# cURL (bash) — Chat Completions
# Prereqs:
#   export SHAREAI_API_KEY="YOUR_KEY"

curl -X POST "https://api.shareai.now/v1/chat/completions" \
  -H "Authorization: Bearer $SHAREAI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{

    ],
    "temperature": 0.4,
    "max_tokens": 128
  }'

// JavaScript (fetch) — Node 18+/Edge runtimes
// Prereqs:
//   process.env.SHAREAI_API_KEY = "YOUR_KEY"

async function main() {
  const res = await fetch("https://api.shareai.now/v1/chat/completions", {
    method: "POST",
    headers: {
      "Authorization": `Bearer ${process.env.SHAREAI_API_KEY}`,
      "Content-Type": "application/json"
    },
    body: JSON.stringify({
      model: "llama-3.1-70b",
      messages: [
        { role: "user", content: "Give me a short haiku about reliable routing." }
      ],
      temperature: 0.4,
      max_tokens: 128
    })
  });

  if (!res.ok) {
    console.error("Request failed:", res.status, await res.text());
    return;
  }

  const data = await res.json();
  console.log(JSON.stringify(data, null, 2));
}

main().catch(console.error);

Security, privacy & compliance checklist (vendor-agnostic)

• Key handling: rotation cadence; minimal scopes; environment separation.
• Data retention: where prompts/responses are stored, for how long; redaction defaults.
• PII & sensitive content: masking; access controls; regional routing for data locality.
• Observability: prompt/response logging; ability to filter or pseudonymize; propagate trace IDs consistently.
• Incident response: escalation paths and provider SLAs.
