Hi Product Hunt! I’m a solo developer, and I built Fius because managing subscription fragmentation and API chaos was completely ruining my development velocity. As software engineers, we often find ourselves trapped in an inefficient workflow: constantly switching web tabs, copy-pasting complex prompts, and juggling individual API keys for OpenAI, DeepSeek, and other providers just to get the best coding results. Fius resolves this friction. I consolidate access to an expansive roster of flagship AI models into a single, unified developer token and a centralized billing system. This allows engineering teams and solo developers to route queries to the best-suited model instantly, without infrastructure overhead or multiple monthly invoices. Here is what is live right now: 1. Advanced Developer Toolkit: A high-performance, cross-platform Terminal CLI assistant workspace featuring native, low-latency autocomplete and advanced multi-file code refactoring workflows. 2. Global Billing Integration: A fully active international merchant billing engine via PayPro Global where 100 platform credits equal 1 USD. You pay strictly for your actual consumption across all models. 3. Production Infrastructure: Fully operational web console hosted on Microsoft Azure cloud enterprise architecture, supported by official startup grants. Our multi-model catalog includes models like gpt-5.4-nano (optimized for near-zero cost terminal auto-completion), DeepSeek-V4-Pro, grok-4-1-fast-reasoning, Kimi-K2.6, mistral-medium-3-5, and many others live in our docs. I would highly appreciate your brutal feedback on the terminal CLI, infrastructure architecture, or any specific models you would like to see deployed next. Thank you for your support, and I am excited to answer your questions in the comments below!
