TypingMind, LibreChat, LobeChat, Open WebUI, NextChat, ChatBox and more. If your chat UI lets you set a custom OpenAI or Anthropic base URL, it works with Grepture — no plugins, no code changes.
Grepture is an open-source AI gateway between your chat client and AI providers. Point any BYOK chat app at Grepture and you get a shared dashboard for every prompt your team sends — cost per user, PII redaction, audit logs, and spend limits — without touching the upstream tool.
Sign up at app.grepture.com and grab your API key from the dashboard.
Find the "Custom endpoint" / "API host" / "Proxy URL" field in your chat UI's settings, paste the Grepture URL below, and keep using your existing OpenAI or Anthropic key.
These are the full endpoint URLs — paste them into clients that expect a complete URL (TypingMind, BoltAI…). If your client only takes a base URL (Open WebUI, LobeChat, ChatBox…), drop the trailing path; the proxy forwards whatever you append.
Set both endpoints if your client supports it. Newer models (GPT-5, o-series) use the Responses API — if you only paste Chat Completions, that traffic bypasses your proxy and goes straight to OpenAI.
https://proxy.grepture.com/openai/<grepture_api_key>/v1/chat/completionshttps://proxy.grepture.com/openai/<grepture_api_key>/v1/responsesKeep your real OpenAI / Anthropic / Gemini key in the client's API key field. Grepture pulls the Grepture key out of the URL and forwards the upstream key untouched.
Every tool below ships with a configurable proxy / base URL setting. Drop the Grepture URL in and you're done.
Per-user, per-prompt token spend across every chat client your team uses. Spot the engineer running up the bill in seconds.
Log every request and response your chat UIs make. Search prompts, replay conversations, and audit team usage.
Strip emails, names, secrets, and customer data from prompts before they hit OpenAI or Anthropic — even when your chat UI has no guardrails of its own.
npm install @grepture/sdk — wrap your client — done.
