We'll detect the provider from the key shape.

Stateless proxy — keys never logged, stored, or persisted. What happens to your key →

Stateless

Keys never persist. The proxy forwards once and forgets.

Latency-aware

p50 / p95 / p99 from a 5-ping benchmark, per provider.

Snippet-first

cURL, Python, Node fetch, axios — copy and ship.

FAQ

What KeyForge is — and isn't.

What is KeyForge?
KeyForge is a free, open-source developer tool that tests Large Language Model (LLM) API keys. Paste a key from OpenAI, Anthropic, Google Gemini, Groq, Mistral, Cohere, DeepSeek, xAI, Perplexity, Together AI, Fireworks AI, OpenRouter, Azure OpenAI, AWS Bedrock, Hugging Face, Replicate, or a local Ollama host, and KeyForge verifies the key works, lists every model it can call, benchmarks request latency, and generates ready-to-use cURL, Python, and Node.js snippets.
Is KeyForge related to the KeyForge card game?
No. This site is a developer tool for testing LLM API keys. It is unrelated to the trading card game KeyForge published by Asmodee / Fantasy Flight Games. The naming overlap is coincidental.
What does KeyForge do with my API key?
Nothing — beyond forwarding it once to the upstream provider so we can read the response. The proxy is stateless: keys are never logged, stored, or persisted. There is no database, no analytics on key values, and no third-party scripts. The full code is open source on GitHub.
Which LLM providers does KeyForge support?
OpenAI, Anthropic (Claude), Google Gemini, Mistral, Cohere, Groq, DeepSeek, xAI (Grok), Perplexity, Together AI, Fireworks AI, OpenRouter, Azure OpenAI, AWS Bedrock, Hugging Face, Replicate, and Ollama (local). Adding a new provider takes about 30 minutes — see the contributing guide.
Do I need to sign up?
No. KeyForge is free and requires no account, email, or signup. Just paste a key and test.
Can I run KeyForge myself?
Yes. The codebase is MIT-licensed and runs on any Node.js host or Vercel. Clone the repo at github.com/dimssu/key-forge and follow the README.
