## Choose when

### Choose eval-view if…

- License: eval-view is Apache-2.0, testzeus-hercules is AGPL-3.0.
- Tags unique to eval-view: agent-benchmark, agent-evaluation, ai-agents, anthropic.
- Also covers Evaluation & Observability.
- When you need to snapshot and diff the behavior of AI agents across multiple platforms, including LangGraph, CrewAI, OpenAI, and Anthropic.

### Choose testzeus-hercules if…

- License: testzeus-hercules is AGPL-3.0, eval-view is Apache-2.0.
- Tags unique to testzeus-hercules: agent, agents, automation, browser.
- When you require comprehensive testing capabilities including UI, API, Security, Accessibility, and Visual validation without code maintenance

## When NOT to use eval-view

- If you are working exclusively with AI platforms not supported by eval-view, such as those not listed among LangGraph, CrewAI, OpenAI, and Anthropic.
- When you do not require regression testing or behavior snapshotting for your AI agents, as eval-view is specifically designed for these purposes.
- If you are looking for a tool that does not involve backend API charges for executing your agent, as eval-view does not skip these charges even with the --no-judge flag.
- If you need a tool that automatically handles the migration from the OpenAI Assistants API to the Responses API without manual intervention, as eval-view requires following a migration guide for this.

## When NOT to use testzeus-hercules

- If your project specifically requires proprietary tools or solutions that cannot be integrated with open-source software under AGPL-3.0 license terms
- In scenarios where deep customization of testing agents is needed as Hercules may offer limited flexibility for altering its core functionalities due to its comprehensive approach
