No-Code AI Agent Platform
A self-serve platform for building and deploying production AI agents — prompt, tools, model and channels configured from a UI. Cut agent delivery from days to minutes. Today it runs multiple production agents, including a customer-support agent handling ~30,000 messages and 44M tokens per day across 6,000+ daily users.

Centralized LLM Routing Engine
One gateway for every LLM call — budget tracking, rate limiting, multi-provider fallbacks and circuit breaker patterns so product teams survive provider outages without noticing them.

Dynamic Tool Framework
Turns any REST API into an agent-callable tool: configure the request, fire a live test call to capture the real response shape, annotate the keys — and the LLM tool schema writes itself. Hand-written integrations: eliminated.
