## Choose when

### Choose agentsys if…

- agentsys is primarily JavaScript; Archon is TypeScript.
- Pricing: MIT licensed tool offers open access for free but may include premium plugins or skills..
- Requirements: Min 2 GB RAM; Requires modern JavaScript environment to run effectively.; Ensure internet connectivity due to reliance on plugins and skills that may require update downloads or external API access for certain functionalities..
- Tags unique to agentsys: agent, autonomous-agents, claude-code, codex.
- Also covers AI Agents.
- Use when you need to automate complex workflows in JavaScript-heavy projects, as it integrates well with JavaScript environments like Claude Code.

### Choose Archon if…

- Archon is primarily TypeScript; agentsys is JavaScript.
- Requirements: - Proficiency in TypeScript is expected to make full use of Archon's features..
- Tags unique to Archon: claude, cli, coding-assistant, typescript.
- Archon ships Docker support for self-hosted deployment.
- - If you need to ensure determinism and repeatability in your AI coding projects using TypeScript, Archon provides the necessary tools without proprietary constraints.

## When NOT to use agentsys

- Avoid for teams not proficient in JavaScript or those preferring languages where agentsys does not provide comparable support.
- Do not use if your project scope is better served by competitors with more specialized skill sets that align closely with niche requirements, as opposed to the general utility approach of agentsys.

## When NOT to use Archon

- - You may avoid Archon if your project does not require TypeScript and specifically focuses on other programming languages where alternative solutions might be more fitting.
- - If deterministic outcomes are less critical than rapid, flexible execution of AI coding projects, the constraints provided by Archon’s design might limit its utility.
