AI Request Gateway
Production-ready LLM reverse proxy with multi-tenant auth, routing, caching, rate limiting, and cost tracking to keep AI usage auditable and sane.
Quick Links
Best for: teams using multiple AI providers who need budgets, guardrails, and a kill-switch before the invoice hits.
LLM Replay Kit
Capture, store, and replay LLM interactions for production debugging. Records full request/response context, provider, model, cost, and latency as portable replay bundles.
Quick Links
Best for: Production AI systems, LLM gateways, regression testing, and anyone who needs to answer “why did it do that yesterday?”
Agent Guardrails Middleware
Agent Guardrails Middleware is close behind. What it is: A drop-in “seatbelt” for agentic workflows: budgets, max-actions, timeouts, tool allow-lists, and a hard kill switch.
Why devs need it: Agents are chaos machines with a credit card. Why they won’t build it: Everyone thinks they’ll “add safety later.” Later is after the outage.
