LLM Gateway 5

One key, every modality—run text, images, video, and code through GPT, Claude, Gemini, Sora, Veo, and Banana from a single endpoint. Two channels, your call: route everyday traffic through the value tier to keep costs down, and flip critical workloads to the official tier when stability matters.
OnAPI is a one-stop AI model API gateway that gives developers a single key to handle text, image, video, and code across every major frontier model—GPT, Claude, Gemini, Sora, Veo, Banana, and more. Turn models into products. Ship ideas.
Two channels, you're in charge: send everyday traffic to the high-performance value tier and stretch every dollar; flip mission-critical calls to the official tier, backed by real paid keys hitting the providers directly. No reselling tricks, no smoke and mirrors, no substituting cheap models for premium ones—just a reliable safety net when it counts.
Fully OpenAI-compatible. Change one line—your base_url—and you're done. Works out of the box with the OpenAI SDK, LangChain, Claude Code, Cursor, Cline, and Cherry Studio. No international credit card required, no juggling bills across half a dozen vendors. Pay with Alipay, WeChat Pay, or crypto, billed by usage, with credits that never expire.

Unified API to route, manage, and analyze LLM requests.
LLM Gateway is a platform that allows users to route, manage, and analyze their Large Language Model (LLM) requests across multiple providers using a unified API interface. It is fully open source and compatible with the OpenAI API format for seamless integration.

Security gateway for LLMs that detects and masks sensitive data and risky code.
Cencurity is an enterprise-grade security gateway designed to proxy LLM and agent traffic. It functions by detecting, masking, and blocking sensitive data, PII, and risky code patterns in both requests and responses. The platform provides a centralized dashboard for real-time monitoring and recording of all interactions as audit logs. It is designed to be compatible with any LLM agent or IDE without requiring code rewrites, ensuring safe and governed AI integration for development teams.

Unified LLM engineering platform for observability, evaluations, prompt optimization, and AI gateway services.
Respan (formerly Keywords AI) is a comprehensive LLM engineering platform designed to help teams build, monitor, and optimize AI agents. It unifies observability, evaluations, prompt optimization, and a unified AI gateway into a single interface. The platform allows developers to trace agent execution paths, evaluate performance using LLM-as-judge or human review, manage prompt versions, and access over 500 models through a single API endpoint. It is built to handle massive scale, supporting trillions of tokens while maintaining rigorous security standards like SOC 2 and HIPAA.

LiteLLM: LLM Gateway for managing and accessing 100+ LLMs in OpenAI format.
LiteLLM is an LLM Gateway (OpenAI Proxy) designed to manage authentication, load balancing, and spend tracking across 100+ LLMs, all while maintaining the OpenAI format. It simplifies the process of using LLM APIs from various providers like OpenAI, Azure, Cohere, Anthropic, Replicate, and Google. LiteLLM offers consistent outputs and exceptions for all LLM APIs, along with logging and error tracking for all models. It provides features like cost tracking, batches API, guardrails, model access, budgets, LLM observability, rate limiting, prompt management, S3 logging, and pass-through endpoints.
