**Typed relationship:** 9router _(alternative)_ rtk

Both 9Router and RTK aim to reduce LLM token consumption, but use different methods (auto-compression vs proxy reduction).

## Decision facts: 9router

- **Adopt for:** An efficient coding tool that connects multiple AI providers to save tokens and avoid rate limits, offering a 20-40% token saving feature with RTK and auto-fallback to free models.

## Decision facts: rtk

- **Adopt for:** Compresses CLI command outputs to reduce LLM token consumption by 60-90%, enhancing cost efficiency.

## Choose when

### Choose 9router if…

- 9router is primarily JavaScript; rtk is Rust.
- License: 9router is MIT, rtk is Apache-2.0.
- Both 9Router and RTK aim to reduce LLM token consumption, but use different methods (auto-compression vs proxy reduction).
- Tags unique to 9router: copilot, codex, chatgpt, ai-gateway.
- Also covers AI Agents.
- 9router ships Docker support for self-hosted deployment.
- - When you need to connect various AI coding tools (like Claude Code, Codex) across 40+ providers.

### Choose rtk if…

- rtk is primarily Rust; 9router is JavaScript.
- License: rtk is Apache-2.0, 9router is MIT.
- Both 9Router and RTK aim to reduce LLM token consumption, but use different methods (auto-compression vs proxy reduction).
- Tags unique to rtk: command-line-tool, ai-coding, agentic-coding, claude-code.
- Also covers Developer Tools.
- - When working on projects where the usage of tokens for Language Models (LLMs) significantly impacts costs, rtk can drastically cut down on these expenses.

## When NOT to use 9router

- - Avoid if you are looking for specialized features specific to a single top-tier AI coding tool, as 9router's strength lies in its multi-provider fallback and token-saving functionalities.
- - If the project requires heavy reliance on expensive APIs where cost is not a concern and direct access without intermediate routing offers better performance or control.
- - For users who prefer manual switching between different providers to maintain full control over which AI services they use at any given time.

## When NOT to use rtk

- - If your project or work environment does not involve substantial interaction with LLMs, the benefits of using rtk in terms of token and cost reduction will be negligible.
- - For projects where CLI output integrity needs to remain unchanged (e.g., for debugging purposes), rtk's compression and filtering might interfere with essential outputs needed for analysis.
