Your Keys, Your Models, Your Data
FlowManner supports every major LLM provider. Generate an API key from your provider, paste it into Settings, and start building workflows in under five minutes.
Bring Your Own Key (BYOK) lets you connect your existing LLM provider accounts directly to FlowManner. Your data stays between you and your model provider — we never store or train on your conversations.
Why BYOK Matters
With BYOK, your prompts and completions go directly to your chosen model provider. FlowManner acts as the orchestration layer — routing tasks, chaining agents, and managing workflow state — without ever seeing your LLM traffic. This means full GDPR compliance, no vendor lock-in, and the freedom to switch models at any time.
Supported Providers
FlowManner works with OpenAI (GPT-4o, o3), Anthropic (Claude 4 Sonnet, Claude 4 Opus), DeepSeek, Google Gemini, Mistral, and any OpenAI-compatible endpoint including local models via Ollama or LM Studio. You can mix providers across different agents in the same workflow.
Step-by-Step
Generate an API Key
Go to your provider's dashboard (e.g., platform.openai.com/api-keys) and create a new secret key. Copy it immediately — most providers only show it once.
Open Settings → API Keys
In FlowManner, navigate to Settings from the sidebar, then select the API Keys tab. You'll see fields for each supported provider.
Paste and Save
Paste your API key into the matching provider field and click Save. FlowManner encrypts the key at rest with AES-256 and never logs it.
Test Your Connection
Click the Test button next to your key. FlowManner sends a lightweight request to verify the key works. A green checkmark confirms success.
