I got tired of copy-pasting to Ollama, so I built a "Postman" for Local LLMs

Hey DEV community! 👋

If you're building with local AI models in 2026, you've probably noticed a glaring gap in our tooling. Web dev has Vite, APIs have Postman, UI components have Storybook... but for local LLM work? We're often still stuck copy-pasting prompts between our code editors, an Ollama CLI, and a basic chat UI.

It completely breaks the flow state. I wanted a better way to iterate, so I built Quantamind.

🧠 What is Quantamind?
Quantamind is an open-source (Apache 2.0) desktop app designed to be a focused, blazing-fast workspace for prompt iteration and model evaluation. It connects directly to your local Ollama instance and acts as a dedicated workbench for your AI dev process.

🛠️ The Architecture: Tauri + Rust + React
For a developer tool, performance and system footprint are everything.

Instead of reaching for Electron, I built Quantamind using Tauri.

Rust Backend: Handles the heavy lifting, local file system interactions, and efficiently manages the streaming responses from the Ollama API without blocking the UI.

React Frontend: Provides a snappy, highly responsive user interface.

The result is a native-feeling app that doesn't eat up the RAM you desperately need for running your local LLMs!

🚀 What's in v0.1?
We just shipped the first version focusing on the absolute essentials to get your workflow moving:

Prompt Editor: With a hot-reload feel so you can tweak and iterate rapidly.

Model Picker: Seamlessly swap between the local models you have installed.

Performance Profiling: Real-time streaming output and token generation timing, so you can actually benchmark how your models perform locally.

🔮 What's Next?
Right now, the Mac universal binary is live in our releases. Windows and Linux builds are dropping next month. We also have an Inspector View coming in v0.4 for deep-dive request/response analysis.

Try it out & Contribute
Quantamind is completely free and open-source. I'd love for you to take it for a spin and let me know what you think.

I'll be hanging out in the comments! Happy to answer any questions about the Tauri architecture, how we handle the streaming state, or anything else about the roadmap.
