Licensing

rayobrowse uses two licenses:

• The repository wrapper, examples, docs, and configuration files are MIT licensed.
• The rayobrowse Browser Binary is licensed separately under the rayobrowse Browser Binary License.

This lets GitHub and package consumers treat the wrapper as MIT while keeping the browser binary protected enough to remain effective against modern bot detection.

Self-hosted use

Self-hosted use is free and unlimited under the binary license, as long as your use is legal, ethical, and does not fall into the restricted commercial categories below.

Allowed uses include:

• Personal, educational, research, and hobby projects.
• Internal business automation.
• Internal scraping, QA, monitoring, AI agent, and data collection workflows.
• Commercial use that is not reselling browser infrastructure or a scraping API.

Restricted commercial categories

The binary license does not allow using the rayobrowse Browser Binary to sell or operate:

• A browser solution, browser API, browser infrastructure platform, hosted browser service, stealth browser service, anti-detect browser service, browser session rental product, or similar offering.
• A web scraping API, crawling API, extraction API, managed scraping service, or similar product where users call an API or hosted workflow and receive scraped data back.

For commercial licensing questions or uses that may fall into those categories, contact [email protected].

Why the binary is separate

We’ve seen projects like camoufox get undermined by anti-bot companies reverse-engineering the source code to detect it. We want to avoid that and keep the browser working reliably for years to come.

Legal & ethics

rayobrowse should be used only for legal and ethical automation and web data collection. Do not use it for credential attacks, fraud, spam, unauthorized access, harassment, malware, or other harmful activity. Rayobyte is a proud partner of the EWDCI and places high importance on ethical web scraping.
