Portkey alternative — observability and control without the proxy layer

Portkey provides an observability and gateway layer that sits between your application and LLM providers — offering logging, metrics, guardrails, and fallback routing. Plugsky is the all-in-one alternative with models built in, so you don't need a separate proxy layer to get enterprise AI capabilities.

What Portkey does well

• Deep observability — logs every request with latency, tokens, cost, and error tracking
• Guardrails — content moderation, PII redaction, prompt injection detection
• Fallback and retry routing — automatic failover between providers with configurable strategies
• Prompt management — version prompts, A/B test, and deploy across environments
• Cost tracking and budgets — per-user spend limits and real-time cost alerts

What Plugsky adds

• Built-in models — 30+ pre-integrated models, no separate provider APIs or keys needed
• No proxy layer — call Plugsky directly, not through a gateway on top of other providers
• Flat monthly pricing — from $20/mo unlimited, including model usage
• Regional data ownership — EU, GCC, APAC, and US data regions
• Enterprise controls — SAML, SCIM, audit log, dedicated CSM
• RAG + agents built-in — no separate vector DB or agent orchestration required

When to choose each

Choose Portkey when you need deep observability across multiple existing providers, advanced guardrails with PII redaction, or prompt management with A/B testing and versioning.

Choose Plugsky when you want a simpler architecture without a proxy layer, built-in models with flat pricing, regional data compliance, or built-in RAG and agent capabilities — all through one API.

Migration effort

Moving from Portkey to Plugsky simplifies your stack — you remove the proxy layer and call models directly. Both use OpenAI-compatible APIs:

// Before — Portkey (proxy to OpenAI)
import Portkey from 'portkey-ai';
const portkey = new Portkey({ apiKey: 'pk-...' });
const chat = await portkey.chat.completions.create({
  model: 'gpt-4o',
  messages: [{ role: 'user', content: 'Hello' }]
});

// After — Plugsky (direct, models included)
import OpenAI from 'openai';
const openai = new OpenAI({
  baseURL: 'https://api.plugsky.com/v1',
  apiKey: 'sk-live-...'
});
const chat = await openai.chat.completions.create({
  model: 'plugsky-pro',
  messages: [{ role: 'user', content: 'Hello' }]
});

Pricing comparison

Usage scenario	Portkey	Plugsky
Gateway cost	Free (10K req/mo) or $99/mo	$0–20/mo (models included)
Provider costs (100K req/mo)	$15–50/mo	$0 (included in flat)
Total monthly (100K req)	$15–149	$20–99
Total monthly (1M req)	$150–599	$99–299

Break-even: At approximately 50K–100K requests per month, Plugsky's $20 Hobby tier (which includes model costs) is cheaper than Portkey's gateway + separate provider fees. For higher-volume workloads, the savings grow significantly.

Limitations

• Shallower observability — Portkey offers deeper request logging, prompt versioning, and A/B testing. Plugsky's observability covers core metrics.
• Basic guardrails only — Portkey has advanced guardrails including custom PII rules and prompt injection detection. Plugsky offers content filtering.
• No prompt management — Portkey's prompt versioning and deployment workflows are not available in Plugsky.

Frequently asked questions

Does Plugsky provide observability like Portkey?

Yes — Plugsky includes usage logs, latency tracking, error monitoring, and cost analytics in the dashboard. Portkey offers deeper observability with prompt management and experimentation features.

Do I need to set up a proxy with Plugsky?

No — Plugsky is a direct API. Portkey proxies requests through their gateway to your existing providers. Plugsky has built-in models, so no proxy layer is needed.

Is Plugsky cheaper than Portkey?

Portkey is free (permanent free tier for up to 10K requests/month) plus you pay your provider costs. Plugsky starts at $20/mo flat with models included. At 50K+ requests/month, Plugsky is typically cheaper.

Can I use Portkey for observability and Plugsky for models?

Yes — many teams use Portkey for observability logging of their existing providers and Plugsky for direct model access. You can even route Plugsky's API through Portkey if you want both.

Does Plugsky support guardrails like Portkey?

Plugsky offers content filtering and basic safety guardrails. Portkey provides more advanced guardrails with custom rules, PII redaction, and prompt injection detection.
