I built SanBlade because I was frustrated by two things:

The proliferation of $20/mo subscription layers just to wrap basic API access. The clunky web interfaces of those wrappers. SanBlade is a web application (built with Next.js, Tailwind, and React) that connects directly to the APIs for OpenAI, Anthropic, OpenRouter, and Google via your own keys (BYOK).

The core focus was building a highly polished, macOS-style workspace. I wanted the UI to feel native, with draggable elements and a dark theme that actually looks good, without locking you into a specific model provider. Keys and data are stored locally.

Stack Details:

Next.js 14 and React 19 for the frontend Local browser storage using Dexie Live React code execution powered by Sandpack I'm currently offering a one-time "Founder License" for $99 (limited to 150 seats) before moving to a standard subscription model.

I’d love to hear your thoughts on the UI architecture or the BYOK approach. Link:https://sanblade.com
