What Portkey does
Portkey is a platform for teams that build applications on large language models. Its core is an AI gateway: one unified API that, according to the vendor, reaches 1,600+ LLMs, with fallbacks between models, load balancing, retries and simple and semantic caching for repeat requests. Around the gateway sit observability (logs, traces, feedback, custom metadata, filters), guardrails, and prompt management with templates, a playground and versioning.
For governance, the pages describe Role-Based Access Control, single sign-on, activity logs and automatic PII redaction before a request is sent to the model. An MCP Gateway centralizes authentication, access and observability for MCP servers. The homepage says integration takes 3 lines of code.
Pricing is freemium. The Developer plan is free forever and includes 10k recorded logs per month, with 3 days of log retention and 30 days of metrics retention. The vendor states it is meant for prototyping and testing, not production workloads. The Production plan costs $49/month and includes 100k recorded logs per month, with $9 overages per additional 100k requests, plus unlimited prompt templates and semantic caching. Enterprise pricing is custom and adds private cloud deployment, VPC hosting, custom retention and compliance options. An open-source gateway that you host yourself is also listed. The site also announces that Portkey is now PRISMA AIRS AI Gateway for enterprises.

Our take
Portkey fits engineering teams that already call several LLM providers and want one place for routing, logging, cost tracking and access control. The $49/month Production plan is a clear entry point, and the free Developer plan lets you evaluate it, though the vendor says it is not for production workloads. It fits less well if you need long log retention on a small budget: Developer keeps logs for 3 days, Production for 30 days. Overages cost $9 per additional 100k requests. Custom security controls, data residency and private deployment require Enterprise, which has no published price. No annual price or trial is shown. The pages also announce a rebrand to PRISMA AIRS AI Gateway, so check what that changes for you.
