Congrats on launch! Creating a 100% client suite of 120+ tools from Next.js 15 and React 19 while mainting 100/100 Core Web Vitals is an incredible achievement in itself.

Minor feedback:

1. I think showcasing privacy-first tools on the UI header (JWT decoders, JSON formatters, hash generators) showing that nothing is processed on the backend would immediately gain you trust for sensitive operations

2. The palette search (Cmd+K) is perfect for exploring such a large ecosystem. Perhaps implementing accelerators for quick actions (auto-pasting what's on your clipboard or quick copy) would be more convenient for day-to-day usage.

3. The ability to save and have an Edge extension with PWA capabilities is much appreciated, being able to debug local environments without a stable connection is a huge plus

Well done on v1!

Thank you so much for the detailed feedback and kind words! 🚀
That point about privacy visibility is spot on — developers often hesitate to paste JWTs or private JSON payload snippets into online tools without proof that it never touches a remote server. We'll add clear client-side privacy badges right on the header and individual sensitive tool cards.
Adding quick-action clipboard accelerators to Cmd+K is a great idea and we'll implement that in our upcoming update.
Really appreciate you checking it out and taking the time to share this feedback!

AI-assisted first-screen copy feedback from the FirstClick Fix project; I checked the public homepage HTML, not performance, network privacy or the tools themselves.

A small expectation mismatch: the header says “ZapyNext PRO,” while the hero promises “100% Free” and the FAQ says there are no fees or usage limits. “PRO” can read as a paid tier before visitors reach that explanation.

If PRO is just branding, consider dropping the badge or explicitly labeling it “All tools free — no paid tier” only if that is accurate. Keep the existing no-login wording near the search action. This would make the entry point's pricing expectation consistent without adding another feature claim.

Thank you for the thoughtful first-screen copy feedback! That is a very sharp observation.

You're completely right — the PRO badge was intended purely as aesthetic branding ("professional grade"), but it unintentionally creates a freemium/paid tier expectation that contradicts our "100% Free, Zero Backend" promise.

We've removed the PRO badge from the header to keep the entry point pricing expectation 100% transparent and consistent with our zero-login, no-paywall model. Really appreciate you taking the time to review the landing page!
