What's Open Source

The complete MeraRAW photo editor application is open source under the Apache License 2.0. This includes the full RAW editing engine, AI assistant integration, mask tools, catalog, and export pipeline.

✓ Photo Editor App

The entire desktop application — Tauri 2, Rust core, native GPU (Metal/wgpu), React/TypeScript UI.

✓ RAW Engine

Full RAW decode, non-destructive editing pipeline, GPU-accelerated rendering with cache-the-chain optimization.

✓ AI Assistant

Natural language editing with Claude integration — sees your edits as labeled slider moves, not hidden filters.

✓ Smart Masks

On-device subject segmentation, sky detection, radial/linear/brush masks with scoped editing stacks.

Note: This marketing/landing website is not open source — only the photo editor application.

Build from Source

MeraRAW is built with Tauri 2 + Rust + React. Follow these steps to build and run locally on macOS, Windows, or Linux.

Prerequisites

2

Clone the Repository

git clone https://github.com/kaimai-apex/MeraRAW.git cd MeraRAW
3

Install Dependencies

npm install
4

Run in Development

npx tauri dev

This launches the MeraRAW app in development mode.

5

Build for Production

npx tauri build

Creates an optimized production build. The installer/binary will be in src-tauri/target/release/bundle/.

AI Assistant (Optional)

To enable the AI assistant, set the ANTHROPIC_API_KEY environment variable to your Claude API key before running npx tauri dev. Without this, you can use MERATECH_ASSISTANT_MOCK=1 for an offline demo mode.

Run Tests

cd src-tauri cargo test -p meratech-core

Runs the full headless test suite (~70 tests covering all phases).

For detailed build instructions, troubleshooting, and platform-specific notes, see the README on GitHub.
