The Nexis ecosystem

Nexis is more than one app — it’s a developer ecosystem. The terminal is the flagship, but around it has grown a family of tools that share a stack (Tauri 2 + Rust + React 19), a design language, and a philosophy: local-first, lightweight, open source, and zero telemetry.

The projects

Section titled “The projects”
Project What it is Stack
Nexis The AI-native terminal & developer environment (ADE) — the flagship. Tauri 2 · Rust · React 19
nexis-ml Python ML engine — train small models on small data, metrics streamed live into Nexis. Python · PyTorch
nexis-ml-rs Python-free, single-binary ML engine — same protocol and run store as nexis-ml, GPU via wgpu, ONNX export. Rust · burn
Nexis Benchmark Desktop app for benchmarking local AI models — ONNX/GGUF across inference backends. Tauri 2 · Rust · React 19
Dev Dashboard Git status across all your local repos in one glance, scanned natively in ~20 ms. Tauri 2 · Rust (git2 + rayon) · React 19
nexisdev.org The marketing site. Next.js 16 · shadcn/ui · Tailwind v4
This wiki The documentation you’re reading, at wiki.nexisdev.org. Astro · Starlight

How the pieces fit together

Section titled “How the pieces fit together”
  • Nexis is the hub. Its ML Lab panel spawns an engine — nexis-ml or nexis-ml-rs — to do real training work, and renders the streamed metrics live.
  • The two ML engines are interchangeable: both speak the same NDJSON protocol and write the same run store, so a run produced by one can be read by the other.
  • Nexis Benchmark closes the loop on local AI: it measures the models you’d run in Nexis (via LM Studio, Ollama, or ONNX), and it drives nexis-ml-rs as one of its real benchmark backends.
  • Dev Dashboard answers “which of my repos needs attention?” before you even open a terminal — and can drop you into one (your $TERMINAL) at the selected repo.
  • Everything visual descends from the Nexis design system: borderless custom window chrome, OKLCH light/dark themes, and the same typography and cursor set. Dev Dashboard is built directly from the design language extracted from Nexis.

Shared principles

Section titled “Shared principles”

Every project in the ecosystem follows the same rules — see Philosophy for the long version:

  • Local-first. Your code, your models, your data stay on your machine. AI runs on your own API keys or fully offline.
  • Lightweight. Tauri and the system webview instead of Electron; the Nexis terminal itself is under 10 MB.
  • Zero telemetry. None of the apps phone home.
  • Open source. All repos are public under github.com/rwetz, Apache-2.0 licensed.
