Llm Gateway

Costrict Proxy is a self-hosted, OpenAI-compatible gateway that converts a single Costrict account subscription quota into reusable API keys, letting multiple AI agents and clients share one account. Built on CLIProxyAPI v7 and running on port 8317 by default, it exposes standard /v1/models and /v1/chat/completions endpoints with a serialized request queue and automatic token refresh. It is the most direct answer to the “one Costrict account, many agents” problem. What is Costrict Proxy? Costrict Proxy is an open-source gateway that sits between your Costrict account and the AI tools that consume it. Instead of giving every agent its own Costrict subscription — which is expensive and hard to manage — you run one instance of Costrict Proxy, connect it to a single Costrict account, and let it expose that account’s quota as standard API keys. ...

If you work with multiple AI coding agents — Claude Code, Codex, Grok CLI, Kimi CLI, and others — you have likely felt the pain of juggling separate API keys, provider endpoints, and model configurations. A Claude Code router solves this by giving you a single local endpoint that sits between your agents and every LLM provider, handling routing, failover, credential pooling, and cost optimization in one place. In 2026, the ecosystem has matured to offer several compelling options, from the full-featured Claude Code Router (CCR) desktop app to lightweight Rust proxies and enterprise-grade Envoy-based gateways. ...

The short answer: Portkey is the best drop-in replacement if you’re running Helicone or evaluating alternatives after the LiteLLM security scare. It covers 200+ providers, adds under 1ms of latency, and gives you routing, caching, and observability in a single package. LiteLLM is still viable for self-hosted open-source use if you pin a pre-compromise version and monitor CVEs actively. Why 2026 Is the Year of LLM Gateway Evaluation The LLM gateway market hit a turning point in early 2026 with two simultaneous events that forced teams to re-evaluate their infrastructure. On March 3, 2026, Helicone was acquired by Mintlify — the documentation platform — and immediately entered maintenance mode, meaning no new features, only security patches and bug fixes. Within the same quarter, LiteLLM suffered a documented security compromise that raised concerns about the supply chain security of open-source proxy deployments. These two events hit simultaneously at a moment when enterprise LLM API spending had already grown from $3.5B in late 2024 to $8.4B by mid-2025 — a 2.4x increase in roughly six months. Teams that had quietly been running Helicone for observability or LiteLLM for routing suddenly had urgent migration decisions to make. Add to this that 37% of enterprises now run five or more LLMs in production, and the case for a robust, multi-provider gateway has never been stronger. This guide evaluates your real options with the current market in mind. ...
