Update — Feb 19, 2026
Spent the night converting ProveCalc from a native Tauri desktop app to a full web application for the live demo. The desktop app talks to a local Python sidecar over localhost — the web version needed that same compute engine accessible over the internet.
What got done:
Next.js 15 frontend deployed on Railway Python sidecar (SymPy + Pint) deployed as a standalone Railway service All compute endpoints (evaluate, solve, unit check, validate, plot) working over HTTPS Template library, AI assistant, variable inspector, and assumption ledger all ported Resizable sidebar panels, favicon, keyboard shortcut guards Clerk authentication scaffolded What's next:
Authentication flow (Clerk) — gate the app behind sign-in Payment integration — one-time purchase, not subscription CORS lockdown and API security — the compute endpoint needs auth tokens, not just origin checks
