E2B vs bifrost
E2B: E2B is an open-source infrastructure that enables running AI-generated code securely in isolated cloud sandboxes. It provides JavaScript and Python SDKs to start and control these sandboxes for AI applications.; bifrost: Bifrost is a high-performance AI gateway that unifies access to over 15 AI providers through a single OpenAI-compatible API. It offers automatic failover, load balancing, semantic caching, and enterprise-grade features for building resilient AI applications that never go down.

When to choose:
- You operate high-throughput production AI applications and need an ultra-fast LLM gateway (50x faster than LiteLLM, <100 µs overhead at 5k RPS).
- You need unified access across 15+ model providers with automatic failover, adaptive load balancing, cluster mode, and semantic caching.
When to skip:
- You are running small low-traffic pet projects where direct provider SDK calls are sufficient without dedicated proxy infrastructure.
- You need visual prompt chaining, vector RAG pipelines, or chatbot web interfaces (Bifrost is an infra-level API router).
