How AI is used
Caltryx is an observability and guardrail layer designed for production AI workloads. It supports tracking cost per agent, workflow, and customer via a Node/JS SDK that wraps LLM calls.
The tool is designed for solo SaaS founders, indie hackers, and small AI startups that require more granularity than a standard API billing dashboard. It supports multi-agent and LangChain workflows, using correlation IDs to trace costs across multi-step pipelines.
Caltryx includes budget enforcement features that may automatically stop agents or block API calls when a specific limit is reached. It also provides a Bring Your Own Key (BYOK) system for managing API keys with encrypted storage.
Buyers should note that the software is currently in pre-launch. Features such as multi-user workspaces or role-based permissions are available on the Scale and Enterprise plans.

Supports daily or monthly limits that can auto-stop agents and block API calls when budgets are hit.
Node/JS SDK
A library that wraps LLM calls with trackLLM() for token tracking and budget hooks.
BYOK System
Allows users to add OpenAI or Anthropic keys which are encrypted at rest using AES-256.
Observability & Tracing
Uses Correlation IDs to provide request logs and token breakdowns across multi-step agent workflows.
Telegram Control Center
A remote interface to check stats, usage, and stop agents via Telegram commands.
