Show HN: FlashRecord – 2MB Python-native CLI screen recorder

Hi HN — I built FlashRecord, a tiny (≈2MB) Python-native CLI tool for screenshots and GIF recordings aimed at developers who want automation-friendly, scriptable screen capture without a GUI.

### What it is

- CLI-first and importable (import flashrecord) so you can plug it into scripts, tests, CI pipelines, or docs generation. - Outputs GIFs (and screenshots) with a pure-Pillow/NumPy implementation of a CWAM-inspired compression pipeline (multi-scale saliency, temporal subsampling, adaptive scaling). - Cross-platform (Windows/macOS/Linux), zero-config defaults, and production-ready with tests/docs.

---

### Why it might be interesting

- Tiny install and no heavyweight GUI/tooling to manage. - Designed for automation: generate evidence GIFs in CI, attach demo GIFs to PRs, or create tutorial assets from scripts. - Compression focuses on preserving visually important regions while reducing file size dramatically in typical UI demos.

I’m happy to answer technical questions, performance numbers, cross-platform quirks, or walk through the compression pipeline. Feedback, issues, and PRs welcome. What it is
