Hey Product Hunt! 👋 I’m incredibly excited to finally launch Lumist Studio.
Over the last year, my workflow became a nightmare of context-switching. I was juggling ClickUp, Canva, Figma, and a dozen random browser extensions just to get a single campaign out the door. Worse, because I refuse to upload proprietary client images to sketchy online compressors, I was constantly dropping into the terminal to run command-line tools just to get WebP files.
I got fed up. So I built the ultimate local-first antidote.
Lumist Studio is a unified suite of 15 premium creator tools that run entirely in your browser.
There is no backend. Zero cloud data transmission. Everything is powered by IndexedDB and your local hardware.
A few highlights from the suite:
• Frame & Scale: Generate gorgeous social mockups and batch-crop images instantly.
• Crush: Hardware-accelerated image minification and WebP conversion (no sketchy uploads).
• Flow: A beautiful Kanban & absolute-timestamp time tracker.
• Match & Hash: Test secure regex payloads and decode JWTs 100% offline.
• 3 MV3 Extensions: Extract typography, colors, and code snippets natively via secure activeTab permissions.
Because all 15 apps share the same local ecosystem, they talk to each other instantly. It’s free, it respects your privacy, and it’s insanely fast.
I’ll be here all day answering questions. Let me know which of the 15 tools is your favorite! 👇

How does this stay "zero subscriptions" with 15 premium apps included — is there a one-time purchase or is the app bundle genuinely free forever with no hidden tier?

Hi @rem1219681! Great question. The bundle is genuinely free with no hidden tiers.
The secret is the architecture: because Lumist Studio is a static export hosted on Cloudflare Pages, and everything runs locally in your browser's IndexedDB using your local hardware, my server costs are practically zero.
Since I don't have to pay for cloud compute, AWS databases, or API processing, I don't need to rent your data back to you through a subscription model. The core tools you see today will remain free. Enjoy the suite!

the local-first angle is genuinely refreshing, especially the regex sandbox that runs without sending my patterns anywhere. Wish more tools worked like this instead of phoning home every five seconds.

Thanks @ouzdjd5! That was the exact motivation for building this.
I absolutely refused to paste sensitive API keys or JWTs into random utility sites. I found myself constantly writing my own one-off local scripts just to decode and test them safely. I finally decided to wrap that secure workflow into a proper UI. Running the regex natively against the browser's V8 engine gives us the convenience of a web tool with zero risk of data leakage. Really glad you appreciate the privacy-first approach!

Can’t recommend this enough. It’s so helpful having these tools in the same ecosystem, and it’s comforting to know that it’s all local (as I’m guilty of using the sketchy online converters you speak of). I’ll definitely be using the typography and color extractors along with the mockup studio regularly. Once again, so efficient having them in the same ecosystem so I’m not jumping between websites.

Hey @kiwisoup! Thank you so much for the incredible support and kind words. You hit on the exact reason why I spent the last year building this.
I got so tired of the cognitive load that comes with context-switching—opening a tab for a typography scale, another tab to generate a palette, and a third tab just to wrap a screenshot in a mockup frame.
Having Hue, Type, and Frame under one single, local-first roof means you can design, scale, and frame your assets in seconds without closing tabs or exporting/importing across different websites.
I'm so glad we can help you ditch those sketchy converters and keep your creative workflow completely fast and private. Let me know if you have any feedback as you use the tools! 🎨🚀

As Launch Day comes to a close, I wanted to say a massive thank you to everyone who checked out Lumist Studio today—especially @rem1219681, @ouzdjd5, and @kiwisoup for the incredible feedback and validation.
Even though we didn't top the leaderboard today, this launch was a massive win for the codebase. In fact, we actually shipped our first major feature update during the launch today: Lumist Crush now supports fully local, sequential bulk-image zipping!
This is only day one for Lumist. The 15 apps and 3 browser extensions are completely free, run entirely on your local hardware, and will continue to be actively developed and maintained.
If you discover this page down the road, please try the apps and leave your feedback below. I'm always listening and building. 🚀
