Frequently Asked Questions
Everything you need to know about FLIN editions.
Is FLIN really free?
Yes. FLIN Core is free — forever. The binary, FlinDB, FlinUI (180 components), all 420+ functions, 1,675 icons, AI Brain, and Admin Console are included at no cost. You can self-host FLIN applications on your own server without paying anything.
What's the difference between Core and Enterprise?
Both run the exact same FLIN binary. Enterprise adds support (24/7 email, dedicated Slack, success manager), compliance (audit logs, SSO/SAML, team management), and infrastructure (SLA guarantee, on-premise deployment, custom fine-tuning). No features are removed from Core.
Can I use FLIN commercially?
Absolutely. FLIN Core is free for commercial use. You can build and deploy production applications on your own servers, VPS, or any infrastructure. No license fees, no per-seat charges, no revenue limits.
What are Cloud Add-ons (BYOK)?
Both Core and Enterprise users can enhance FLIN with external AI services using their own API keys. Functions like ask_claude(), ask_openai(), ask_grok(), and ask_mistral() connect to external providers. You pay the provider directly — FLIN doesn't add any markup.
What about the local AI? Do I need an API key?
No. FLIN's built-in AI Brain uses IBM Granite 4.0, which runs 100% locally after a one-time model download (~400MB). Auto-correction, self-healing, and the AI Brain features work offline with no API key required.
Can I migrate from Core to Enterprise?
Yes — your code works unchanged. Enterprise just adds support, SLA, and compliance features. Contact [email protected] to upgrade.
When will FLIN Cloud pricing be announced?
FLIN Cloud pricing is TBA. When launched, it will offer managed hosting for both Core and Enterprise users. Follow us on X (Twitter) or Discord for announcements.
