Hi HN!I've been building this solo for about three and a half years. I kept trying every new project/notes tool (Notion, Asana, Trello, etc.) and always ended up back in a plain text file. I wanted something that felt like a text editor on first touch but could grow into real structure when you needed it.https://lightwave.so (desktop only)The tech stack is Laravel, MySQL, Redis, and hand-rolled JavaScript on the client. No frameworks like React/Vue/etc. ~270 lines of jQuery (out of 80k+ total LOC) for a few legacy DOM utilities, plus IndexedDB for local persistence. Real-time collaboration uses a hybrid approach: HTTP/2 POST for resilient ops + WebSockets via Laravel Reverb for live cursors,
