A LiteLLM alternative with observability, guardrails, streaming, cost tracking, intelligent routing, sticky sessions, failover, real-time logs and usage tracking. Prod ready.

Choose it when you need cluster mode and tighter per-request overhead at high RPS with the same Go single-binary model.

Fastest enterprise AI gateway (50x faster than LiteLLM) with adaptive load balancer, cluster mode, guardrails, 1000+ models support & <100 µs overhead at 5k RPS.

Choose it when you want BYOK marketplace routing plus traffic-learned model/cost recommendations, accepting a Python service.

Experiential is the open source, zero markup gateway for BYOK, self-hosted and 1000+ marketplace models. It learns from your traffic to cut costs, recommend better models, and train a specialized model you own.

Choose it when you want a TypeScript gateway with bundled usage analytics and admin UI instead of a single Go binary.

Route, manage, and analyze your LLM requests across multiple providers with a unified API interface.

Choose it when self-service virtual keys and per-key budgets are the priority and a Python runtime is acceptable.

Open-source, OpenAI-compatible LLM gateway you run yourself. One endpoint for 40+ providers, with virtual keys, budgets, and usage tracking.

Choose it when you also need embeddings, ASR/TTS and image endpoints with billing and rate limiting on the JVM.

Bella OpenAPI是一个提供了丰富的AI调用能力的API网关，可类比openrouter，与之不同的是除了提供聊天补全(chat-completion)能力外，还提供了文本向量化(text-embedding)、语音识别(ASR)、语音合成(TTS)、文生图、图生图等多种AI能力，同时集成了计费、限流和资源管理功能。且集成的所有能力都经过了大规模生产环境的验证。

Choose it when you need the broadest provider/SDK ecosystem and Python extensibility, accepting a heavier Python deployment.
