What’s your biggest frustration when using "global" tools that are clearly built with English-first assumptions? I'm only annoyed when I have to learn that a product isn't working with non-English input. I've encountered problems with the decimal point and thousands separators for numbers or text input only accepting US-ASCII letters even for things like names. All other things, I can tolerate....

Let me state first that I have no experience with any of these tools. My main business is SEO consulting though and there are some parallels. As nobody else was answering yet, I hope I still can give you some advice. I see how my customers struggle to gather and analyze all kinds of (SEO-related) data, using lots of great tools. Over the years I‘ve learned three things: Ensuring data quality...

Hi Product Hunt 👋 I'm Stefan, the solo dev behind Tablecruncher—a fast, minimal CSV editor I originally built to handle all kinds of CSV files that Excel or web apps choke on. What makes Tablecruncher different? Opens multi-gigabyte CSVs really fast Native C++ app (Windows, macOS & Linux) No telemetry, no nonsense Fully open-source under GPL v3 JavaScript as its embedded macro language Why open...

I think there ain't neutral media. The process of selecting what to publish violates neutrality already. But I don't think this is a problem, when and if the media platform… at least tries to be as balanced as possible clearly states its core principles doesn't try to appear "neutral" while it tries to influence by pushing the algorithm in a certain direction. If the society it operates in is...

I'm surprised you find this monetization model convincing. To me, it borders on blackmail—getting users hooked into a workflow, possibly involving lots of data, and then one day starting to charge for a feature that was previously free. While this approach might work for larger companies, I think it's a surefire way to drive users away from your product.

Yes, had one case where a site I was responsible for was hacked. It was a Wordpress site for a client who did the web hosting and also had admin access, so we never sorted out what the reason was. For my own projects, I love static site generators. I use Hugo a lot, while one site is running with its own custom-made site generator. To hack a static site is really hard, as you have to hack the...
Have you ever had your website hacked even though you thought it was secure?

My workflow completely relies on the Apple default apps now. Especially Notes is what I use all the time. I would be lost without it.
What’s the Most Useful “Non-AI” Tool You Still Rely on Daily?

I'm not sure I'd agree with you on "We’re in the age of the Minimum Lovable Product (MLP)". Yes, the AI tools make it way easier to polish a product, but that would just result in a "Minimum Polished Product". The tools only help you to make it look good on the surface, but they won't help you a lot when it comes to defining user interactions or how features should be designed. To adapt the...

Is It Crazy to Build a Local App in a Browser-First, AI-Driven World?
Every day, the PH feed is packed with shiny new SaaS tools—most of them browser-based, many of them AI-infused. It’s exciting, no doubt. But compared to a time not so long ago, something seems missing: local desktop apps. They’re rare now, and it makes me wonder—are native apps still worth building, or have they quietly slipped into the realm of nostalgia? After all, web apps offer clear...

I'm not sure how narrow you'll define "productivity". But smaller tools that really helped me get more productive are Hugo (static site generator), Bruno (local API client) and Marp (a local markdown-to-slides tool). And I use TextMate (a text editor for macOS) quite a lot. Of course, for coding it's VS Code, but TextMate is always running and I have typically lots of windows open to draft...

Looks good. Is it possible to sort by Newest, as in the web interface?

Wow, this looks brilliant! A great idea, and as far as I can tell from the video and the screenshots, wonderfully implemented. Just like the old Logo turtle with nowadays graphics, a touch of robotic and all the modern IDE sugar like context sensitive help and even a debugger. (And some bonus points for the Pascal inspired syntax.) I hope this becomes a huge success!

This looks promising, but I don't get how I get to the calendar view? And it would be great to have more time zones for us Europeans.

I think the idea has potential, the GUI looks rather boring, though. To be useful, users of your app should really love to work with it. A great and compelling UI is a must for that. Judging by the screenshots, I wouldn't love to use it.
