What is Passy?
Passy gives developer teams easy and secure access to the best open-source coding models like Kimi, DeepSeek, GLM and Qwen—without surprise token bills, proprietary lock-in, or dealing with GPU hardware, compatibility issues, and compliance.Use your existing tools (Cursor, Kilo, Warp, IDE plugins) with
drop-in OpenAI & Claude-compatible API keys, routing to our EU-hosted models with zero setup. Checkout our handy guides for integrating with tools like Kilo Code, Claude Code and more here.
Unified Model Routing
Use our open-source models with our unlimited subscription, and keep using
models from OpenAI (Azure), Anthropic (AWS), Gemini (Vertex).\

Problems We Solve
Unpredictable Token Costs
Unpredictable Token Costs
⭕ The Problem:
Using AI code editors like Cursor, Kilo Code, Claude Code and Warp becomes extremely expensive easily reaching €100/day per developer and scales unpredictably as AI becomes central to your daily workflow.
Providers like OpenAI, Anthropic and Google aggressively overcharge for inference, train on your data, and lack proper EU compliance.💡 Passy’s Solution:
Predictable subscription pricing per developer.
Unlimited Passy-token usage with fair usage limits depending on your plan, starting at €60/m per seat, we never store your chats, messages, or prompts.
We promise we’ll never train on your data and for an enterprise license enable self hosting contact us at hello@passy.ai with more info your project.

Too many API keys
Too many API keys
⭕ The Problem:
Constantly updating API keys for different providers, new model releases, changing limits, and compliance checks create chaos in your team setup.💡 Passy’s Solution:
One unified API that routes to trusted providers like Azure (OpenAI), AWS Bedrock (Anthropic), Nebius, Vertex, DeepInfra and more.
Use our routing (5%) or bring your own keys (€50/month).

Slow Inference & Compatibility Issues
Slow Inference & Compatibility Issues
⭕ The Problem:
AI coding tools break easily when providers throttle, change APIs, move regions, or release new model versions.
Latency fluctuates; compatibility breaks; nothing feels consistently fast.💡 Passy’s Solution:
We host key models directly in the EU for consistently fast, low-latency performance.
Our API remains compatible with tools like Cursor, Kilo Code, Claude Code—even when those tools shift their integrations.
Integrate Passy once, and your setup stays stable.

Vendor Lock-In & Data Privacy
Vendor Lock-In & Data Privacy
⭕ The Problem:
Tools like Cursor & Warp frequently change pricing, rate limits, and policies.
”$20/month unlimited” becomes stricter every few months more timeouts, rate limits, more throttling, and much less value. With increasing bills every single month.Most of these editors route requests through OpenAI, Anthropic or OpenRouter, meaning:
Predictable model access via simple per-developer pricing.
Fully EU-hosted. No lock-in. No surprise token bills.
Zero GPU management your team just uses the models they want.
Always the newest releases available the same day.
