Decision brief
Caveman reduces token usage by 65% through minimalistic language for coding agents, supporting two sizes and primarily written in Go.
Good fit when
- When you need to significantly reduce token usage in coding agents, as Caveman can cut usage by 65% through its simplified language style.
- If your project requires a tool that is primarily written in Go and supports two different sizes for flexibility in deployment.
Avoid when
- If your project requires a fully OSI-approved open-source license, as Caveman's engine-linked runtime is BSL-1.1, which is not OSI-approved until a future date.
- When you need a tool that does not involve a trademarked name and logo, as Caveman is trademarked and has specific guidelines for its use.
- Pricing:
- freemium - The skill, Agent SDK, and initializer are free under MIT license. Hosting Caveman for third parties requires a commercial license.
- Requirements:
- Min 1 GB RAM; Caveman is primarily written in Go and supports two sizes, allowing for flexible deployment.
