# E2B alternatives > Looking for an alternative to E2B? 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. E2B is open source, so the list below includes both other self-hostable projects and commercial products. E2B's own profile notes it may not be the right fit if you want no account or infrastructure; use needs an E2B API key or your own self-hosted deployment. If that's you, the options below are worth comparing.

Showing the 10 closest of 34 agent infrastructure indexed here. Complete list: https://agentsearchengine.app/category/agent-infrastructure ## FAQ **What is the best alternative to E2B?** It depends on whether you'd rather self-host or buy a managed product. daytona is the most widely-adopted open-source alternative (72k GitHub stars); Browserbase 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 E2B?** Yes. daytona, mem0, and Langfuse 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 E2B 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. --- Source: [Agent Search Engine](https://agentsearchengine.app) — https://agentsearchengine.app/alternatives/e2b
