E2B Free Hobby Tier & $100 Usage Credits

Overview

E2B provides dedicated, secure cloud sandboxes designed specifically for AI agents, code interpreters, and autonomous developer workflows. Under the Hobby Tier, developers receive $100 in one-time usage credits without needing to supply a credit card upfront.

The service enables LLMs and AI applications to run untrusted code in isolated microVM environments, offering complete programmatic control through official Python and JavaScript/TypeScript SDKs.
