## FAQ

**What is the best alternative to zerostack?**
It depends on whether you'd rather self-host or buy a managed product. gemini-cli is the most widely-adopted open-source alternative (106k GitHub stars); Claude Code is one of the commercial options. Compare the full list above on adoption, license, and pricing.

**Is there a free or open-source alternative to zerostack?**
Yes. gemini-cli, openinterpreter, and jcode are open-source coding agents 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 zerostack alternatives ranked?**
Every product in the coding agents 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.
