You roasted my MVP. I listened. Here is v1.3 (Crash-proof & 100% Local)
Hi everyone,
Last time I shared my Smart Watermark Tool here, the feedback was brutal but fair. You guys pointed out that while the idea was good (privacy-first watermarking), the UX was clunky and losing data on page refresh was a dealbreaker.
I spent the last few days coding non-stop based on your suggestions. I'm proud to ship v1.3 today.
Here is what changed based on YOUR feedback:
✅ Crash Proof (The "Ghost" System): Accidentally refreshed the page? No problem. The app now saves your workspace state locally. Your images are restored instantly. ✅ E-commerce SEO Renaming: You asked for file naming for Vinted/Etsy. You can now auto-rename 50+ files (e.g., Vintage-Levis-01.jpg) in one click. ✅ 100% Privacy Badge: I clarified the tech stack. It uses Canvas/Wasm. Images never leave your browser. I added a 50MB limit to prevent browser crashes on mobile. ✅ One-Click Demo: Added a "Try Demo" button so you can test the tool without hunting for a photo on your drive.
The Tech Stack: Next.js, Tailwind, and heavy use of localStorage for state persistence.
I would love to get a "Round 2" of feedback. Did I fix the pain points?

Thanks for pushing me to improve!

Nice
Impressive turnaround on the v1.3 updates! Managing local image processing with Canvas/Wasm can be tough, so setting that 50MB limit is a very practical fix for stability. We're currently building a mental wellness app with AI agents and a Python backend, and we've been exploring similar privacy-focused local processing to keep sensitive data out of the cloud. This is a great example of listening to user feedback!
Thanks! Dealing with browser memory limits while keeping everything local is definitely a balancing act.
I actually just pushed a micro-update (v1.3.1) moving the storage layer to IndexedDB to make it even more robust against crashes during large batches.
Regarding your app: 'Local-first' for mental wellness is a huge selling point. People are rightly paranoid about having that kind of data sent to the cloud. Best of luck with the build, it sounds like a vital tool!
Nice iteration speed — shipping fixes within days based on feedback is the right approach.
The localStorage persistence for crash-proofing is smart. Curious: did you consider IndexedDB for larger file handling? I've seen localStorage hit size limits (~5MB) with image-heavy workflows.
Also, love the privacy-first angle. That's increasingly important for tools handling user content.
Thanks! Glad you like the privacy-first approach.
You hit the nail on the head regarding localStorage limits (that 5MB cap comes fast). 😅
For this v1.3, I'm using localStorage primarily to persist the application state (watermark settings, text, position, opacity) which is super lightweight.
For persisting the actual heavy image blobs in case of a crash, you are absolutely right: IndexedDB (likely via a wrapper like idb-keyval or Dexie.js) is the next logical step for v1.4 to handle high-res workflows without hitting quotas.
Thanks for the technical check, adding IndexedDB to my roadmap right now!
That's fast! Good to hear IndexedDB solved the heavy asset issue. Let me know how it performs with larger batches — always curious about real-world browser storage limits.
Nice separation of concerns — state vs. heavy blobs. Dexie.js makes IndexedDB feel almost as simple as localStorage. Looking forward to v1.4!
You were spot on about the localStorage limits! I just pushed v1.3.1 which moves all heavy assets (images/logo) to IndexedDB. Now it handles heavy sessions without breaking a sweat. Thanks for the tip!
