## Choose when

### Choose ax if…

- ax is primarily TypeScript; RagaAI-Catalyst is Python.
- License: ax is AGPL-3.0, RagaAI-Catalyst is Apache-2.0.
- Tags unique to ax: agent-memory, agent-observability, ai-agents, bun.
- For projects requiring detailed observability and memory management specific to AI-driven coding agents

### Choose RagaAI-Catalyst if…

- RagaAI-Catalyst is primarily Python; ax is TypeScript.
- License: RagaAI-Catalyst is Apache-2.0, ax is AGPL-3.0.
- Tags unique to RagaAI-Catalyst: agentic-ai, agentic-ai-development, agentneo, agents.
- When you need comprehensive tools for the observability of complex multi-agentic systems.

## When NOT to use ax

- Avoid if seeking a tool agnostic to AI-specific functionalities like those for Claude Code and Codex
- Not recommended when looking for solutions outside local-first approaches in TypeScript environment

## When NOT to use RagaAI-Catalyst

- When you prefer a language-agnostic solution or require support outside of the Python ecosystem.
- If your primary need is focused solely on basic monitoring without advanced debugging and evaluation features.
- For projects that do not utilize multi-agentic systems or do not benefit from timeline and execution graph visualizations.
- In scenarios where a fully managed service with no self-hosting requirements is preferred.
