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, presence, and edits.
This is a pre-release stress test, not a launch. Lightwave will be a paid product. Right now I'm opening it up because no amount of solo testing replicates getting punched in the mouth by real traffic.
The link above has a button to create a test account in 1 click.
Known rough edges: the cursor and selection system are built from scratch (like VS Code, not a contenteditable wrapper), so there's a lot of surface area. Some keyboard shortcuts may be missing. Desktop only, accessibility not yet implemented. I'm shipping fixes in real time.
There's a "Submit Bug or Feedback" button inside the app if something breaks. Happy to answer any questions about the architecture, or anything else.
Some highlights:
- Paste markdown in, get native blocks. Copy blocks out, get markdown back.
- Hierarchical document, structure. Hierarchichal file manager.
- Live collab with shared cursors, selection, and presence.
- Code blocks with syntax highlighting. LaTeX math blocks.
- Full data export: markdown, JSON, and attachments. No lock-in.
- Full undo/redo with cursor restoration.
I would also make a small suggestion, which is that there is really no need to emphasize the fact that it's hand-written or without React or etc. While I suppose a small segment of users do truly care that you didn't use React, I think the primary consideration for most users will be how the app works. I would suggest mentioning how your technical decisions affect the user experience: is the performance better - and if so, can you quantify that?
So the problems I was thinking about were collaboration and content management between teams. But I also wanted it to work really well as a private personal tool. So in a way it's two tools in one. You can enjoy it solo, and then the hope is you've found something you like and now you can bring a team into it
Re the tech framing, I mostly mentioned it because I figured HN would find it interesting since it's the less taken path. Apologies if it came across as unrelated to the product.
As for the tech framing - I imagine you'll get lots of responses on that, and I'm sure it works for some people. Speaking personally, I think it irks me in particular because I feel that "React is slow" isn't really true -- but hey, we can sidestep that whole argument if you just tell me that your app loads a 100GB text file in 0.1ms or whatever :)
On the React thing, I never said React is slow! I think it's great for a lot of things. I just chose a different path because I wanted to understand every part of the main product stack. I didn't use OT or CDRT for the same reason... :|
(AKA: I'm not sure it's a good idea to use someone else's long-standing well-known brand in the digital space as name for your own digital space project)
- on non-supported browsers (eg. mobile) don't render the app, show a message instead
- Shift + Home/End for selecting text doesn't work
- Ctrl + N for a new page doesn't work
- things like the above ^, while it may be trivial, will turn off people who will not spend more than 10-20s to evaluate
- you're refer the simplicity of text files, but the editor is not fixed width, it's more like a Markdown-ish editor, closer to Google Docs with its default styles
- when typing - it creates a list, but the list's left margin (where the - starts) is not aligned on the overall left margin of the page, it's very annoying to me
- to me, this is too far away from the simplicity of a text file — this comment, I'm writing it up in Sublime in plain text, and then I'll copy it to Chrome/HN, but I wouldn't do it in your tool — I love being able to Alt-Tab to Sublime, hit Ctrl+N to get a new "file" which is a temporary/ephemeral workspace for typing text, typing and getting sasisfying fixed-width readable text, and then copy/pasting it to my destination, which almost always has a less pleasant editor
- eg. I also write my non-trivial ChatGPT conversations like that ^
- one of the few exceptions is Google Docs, I can directly work into that
- the reason I ended on Google Docs: after a few minutes of playing around, it's not clear to me how using your product would be significantly better for me than using Google Docs for notes (which I don't) — I can use GDocs to write roughly Markdown-equivalent structure, and there's plugins to import/export Markdown — and GDocs is backed by Google, has a working editor, apps, multi-user support, commenting, Google ecosystem integration, etc.
One thing that's weird is that things like that are so easy for me to implement it's just sugar on top. Honestly I would just love to have a few folks tinkering with it saying hey it needs these few things. Just hard for one dev to think of all the things!
3.5 years solo is serious commitment. What was the hardest part ... the real-time sync or getting the editor to feel right?
;-) love the Office Space references
Also, I wanted to make the main guest account name Robert'); DROP TABLE but I chickened out and made it a bit more normal.
On the collab side, any limitations on simultaneous users? Like just a couple at a time or can handle a team?
Congrats on the launch!!
will look into ctrl backspace to delete words like that idea
- flickering
- keyboard appears on readonly document
- can select info text that should not be user selectable
- menu items melt into each other
- can‘t summon keyboard on editable content
- grabbing elements in a document and pulling them up leads to page refresh
- I saw a styling menu pop up once: No idea how I got that.
I am sorry but this is unusable and an awful experience on my iPhone.

Absolutely nothing here works, besides the anonymous login.
Mobile isn't supported yet. Sorry about the bad experience though, I should probably add a more visible warning for mobile visitors.
