VEED

Build a deliberately narrow personal substitute for VEED, not a full clone. Use exactly this stack: Python 3.12 + FastAPI + FFmpeg + React. Primary job: Build a local online video editor workflow that imports user-owned media, applies the core edit or transformation, previews it, and exports a standard file. Start from an empty folder and create the complete working project. Make the default mode single-user and private. Store user data locally unless the core job requires the declared self-hosted database. Do not add analytics, telemetry, ads, or third-party accounts. Put every secret and external credential in .env and provide .env.example. Use realistic sample data that is clearly labelled and easy to delete. Implement the smallest polished interface that completes the core loop end to end. Include clear empty, loading, validation, success, and failure states. Add import and export so the user is not trapped in the app. Use accessible keyboard navigation, labels, focus states, and sensible contrast. Validate untrusted input and never log secrets or private file contents. Deliberately exclude these paid-product advantages: production codecs, rendering speed, and media templates; hosted recording reliability; large-scale rendering. Do not fake integrations, network effects, proprietary data, model quality, compliance, or security claims. Where an external API is optional, keep the app useful without it and explain the degraded mode. Write focused unit tests for the data model and the most important workflow. Add one end-to-end smoke test that proves the core loop works. Create a README with setup, permissions, architecture, data location, backup, and limitations. Add scripts for install, development, test, build, and a production-style local run. Run the tests and build before finishing, then fix errors rather than merely describing them.
