What Is LayerFlow? The AI Workspace with BYOK, Prompts, and Budgets

LayerFlow is a bring-your-own-key (BYOK) AI workspace. You connect the API keys you already have — OpenAI, Anthropic, Google, DeepSeek, and hundreds more — and LayerFlow gives you one place to write prompts, route across models, set hard budget limits, and track spend. It is the layer between you and your LLM providers.

Most people use ChatGPT or Claude through hosted subscriptions. Others start scripting against raw APIs and quickly end up with key sprawl, scattered prompts in chat history, and surprise bills. LayerFlow solves the middle ground: full control over which model you call, with the guardrails that keep spend sane.

What LayerFlow actually does

• BYOK gateway: connect your own keys and route every call through one OpenAI-compatible API.
• Prompt workspace: organize, version, and share prompts instead of digging through chat history.
• Hard budget limits: set a monthly cap and LayerFlow blocks requests before you overspend.
• Spend analytics: see cost per project, per key, per model, and per prompt.
• Multi-model routing: pick the cheapest or fastest model per task automatically.

Why bring-your-own-key matters

With a hosted subscription you get one model family and a fixed price. With BYOK, you bring your own keys, pay the provider directly at their rates, and choose whichever model fits the task. LayerFlow never resells tokens — it optimizes how your own keys are used.

Is LayerFlow right for you?

LayerFlow fits three kinds of users: developers building AI features who want a managed gateway, freelancers and teams that want a shared prompt library, and anyone tired of surprise AI bills who wants hard budget limits without building them from scratch.

Getting started

1. Create a LayerFlow workspace.
2. Connect your OpenAI, Anthropic, Google, or DeepSeek API key.
3. Open the prompt workspace and draft your first prompt.
