E2B Fragments

Fragments, made by E2B, is a platform for building and deploying AI-powered applications within secure, sandboxed environments, letting developers generate and run AI-created code without risking their own infrastructure. It leverages E2B's sandbox technology to isolate AI-generated code execution, giving developers a safe space to test and iterate on AI application output before deployment. The project is open source, with its code publicly available and maintained on GitHub alongside E2B's broader sandboxing infrastructure used by AI developer tools. Fragments serves as both a reference implementation and a usable platform for teams building products where AI agents need to write and execute code safely. Pricing is open source: the project is free and publicly available, with E2B's underlying sandbox infrastructure offering its own separate usage-based plans for teams building on top of it.
