Retina is a Mac screen recorder built for polished demos. Auto-zoom into the action. Cursor paths cleaned into smooth arcs. 4K export, optimized file sizes. Recordings look cinematic out of the box — no post-production needed. Built for product demos, tutorials, and feature walkthroughs that need to look professional without hours in editing. Currently in beta. Free. No watermark. Made by BlendPixel.

FirebaseAn app development platform backed by Google

Supabase
ConvexFirebase handles Retina's auth, license sync across a user's devices, and crash telemetry. Single SDK for an Electron app, generous free tier, and Google-backed reliability we don't have to babysit. Supabase was the closest second — Postgres familiarity is nice — but Firebase's real-time sync and offline-first handling for a desktop app was the bigger fit. Convex was tempting but the platform lock-in gave me pause.

Also considered:
Mistral AI
DeepSeekTwo reasons. (1) Context retention on multi-file Swift/TypeScript refactors — Retina's smart-zoom heuristics interact across the whole codebase. Claude's 1M context held the whole thing in head; DeepSeek and ChatGPT both lost the thread on long sessions. (2) Honest pushback over confident hallucination — Claude flags when something won't work in AppKit instead of shipping a plausible-looking wrong answer. Saved hours of debugging. Plus Claude Code in the terminal: most of Retina was built this way.

Pixi.jsFast lightweight 2D library that works across all devices

p5.js
Three.jsPixi.js powers Retina's cinematic effects layer: smart-zoom interpolation, cursor smoothing, frame styling, background gradients. WebGL-accelerated 2D rendering with a mature filter system. Three.js was overkill for 2D-only work; p5.js wasn't built for production performance. Pixi hit the sweet spot — GPU-fast, filter-rich, predictable frame budget.
