One OpenAI-compatible endpoint for all your coding agents. The routing policy lives in your account, not inside each tool. • Run DeepSeek 4.1 Flash (or other models) inside Codex, and keep your workflow • Give every API key its own daily budget, enforced per request • Explicit fallbacks: on a 5xx, 429 or timeout, try your next model • See remaining weekly quota and reset dates across Codex accounts Supports paid usage, or bring your own provider keys.
Looking beyond Zerg Router? For strong reasoning and coding, try DeepSeek. Build agentic engineering pipelines with Kilo Code. Prefer unified AI access? Use Eden AI or the standardizing SDK liteLLM, and add observability with Helicone AI.
