# cua alternatives

> Looking for an alternative to cua? Below are the agent infrastructure in our index that do a similar job — open-source options are ranked by real maintained adoption (GitHub stars and recent commit activity), never by sponsorship. cua is open source, so the list below includes both other self-hostable projects and commercial products.

cua's own profile notes it may not be the right fit if you need a runtime older than Python 3.11. If that's you, the options below are worth comparing.

## FAQ

**What is the best alternative to cua?**
daytona is the most widely-adopted open-source alternative in our index (72k GitHub stars). The full ranked list is above — the best fit depends on your language, license, and budget.

**Is there a free or open-source alternative to cua?**
Yes. daytona, mem0, and gateway are open-source agent infrastructure you can self-host for free — you still pay for the infrastructure you run them on and any model or API usage. See the ranked open-source list above.

**How are these cua alternatives ranked?**
Every product in the agent infrastructure category is a candidate. Open-source alternatives are ranked by maintained adoption — GitHub stars plus recent commit activity — so you see what's genuinely used, not abandoned. Commercial products are listed separately and alphabetically, because stars don't measure commercial adoption. Sponsored placement is always labeled and never affects the ranking.
