Local-first · open core · Apple Silicon

Every open image model.
Running on your machine.

Planar is a local studio for image generation — from a one-click result to iterative, instruction-driven refinement. Diffusion and beyond, on the hardware you already own.

One prompt · then keep going

Generate a result. Then talk it into shape.

Most images aren't right on the first roll. Planar's refine loop lets you describe a change in plain language — "make the sword glow blue" — and applies it with an instruction-edit model, without re-rolling the whole image.

Built for the whole open stack

From a first generation to a research rig.

The same app handles a one-line prompt and a deep model-management workflow, running locally on Apple Silicon.

Apple Silicon (arm64)

The first release is being prepared for macOS on Apple Silicon, with image generation running locally on your Mac.

Sandboxed plugin pipeline

Extend Planar with WASM plugins — no network or filesystem access by default. Load one, activate it, and batch-run it across every image in your gallery.

WASM · no WASI · plugin API

Experimental research models

Because it speaks Hugging Face Diffusers natively, Planar runs the newest research checkpoints the day they drop — not months later.

HF Diffusers native

Beyond diffusion

Background removal ships built in. Upscalers, segmentation and restoration models run as plugins on the same ONNX runtime.

100% local & private

Generation runs on your hardware. No uploads, no prompt telemetry, no queue — your work never leaves the machine.

No cloud · no account

Agent & MCP ready

Drive Planar from an agent session over MCP — queue jobs, poll status, stream results — while the same queue powers the UI you click through by hand.

Models

Bring any checkpoint. Planar figures out the rest.

Point it at a folder or a Hugging Face repo. Planar detects the architecture, picks sane VAE and sampler defaults, and loads — swapping backends without leaving your project.

  • Diffusers & stable-diffusion.cpp backends, hot-swappable
  • Auto VAE, sampler and resolution detection
  • LoRA stacks and ControlNet built in

Two backends. One switch.

Run the same project on whichever engine fits the job — a lean quantized runtime or the full research stack. Pick per project, swap anytime, no reinstall.

Beyond diffusion · WASM plugins

Bring your own image models.

Planar runs any ONNX image model as a plugin, sandboxed with no network or filesystem access. One ships in the box; drop in the rest.

BGBackground removerbundled
clean alpha matte
One-click subject isolation with a crisp alpha channel — ready for compositing nodes. Ships with the app, u2net-based.
DTPS1 / Bayer ditheringexample plugin
ordered dithering
A reference WASM plugin that applies retro ordered dithering — the template for building your own image-processing nodes.
+Add ONNX model

Point Planar at any .onnx graph, wrap it with the plugin SDK, and it shows up as a loadable, batch-runnable plugin.
