We've got a great roster of participating companies for the month-long Voice AI course and community events series that starts this week.

For the past 10 years, whenever I needed to call an international number, I used Skype. It had my back when I had to clear things up with the US university admissions from Austria, arrange a hotel pickup in Bali, or call my EU bank to see why my card was blocked while I was trekking through Argentina. I could call anywhere in the world for cents, and it was delightful.

In February 2025, Microsoft announced it was closing Skype down, and on May 5 it officially stopped operations. I was really sad when I heard the news with Skype, a huge chunk of my life disappeared. It felt the same way as if, one day, nobody would be playing on Call of Duty 2 servers anymore (that hasn t happened yet, right?).

Anyway, here I ve compiled a list of the top 6 alternatives to Skype for international calling. I used the following criteria to select them:

1. You need to be equal partners

Tim (my cofounder and co-CEO) and I started with quite asymmetric experience.

I had previously been a VP of sales, responsible for sales, support, and account management. Tim was an insanely talented, 23-year-old engineer, and was much earlier in his career I m nearly 10 years older.

Hi there

PontaHR gets updated every month with changes big and small. Read about the new and shiny April features.

Prompting is everything in the age of vibe coding. Knowing how to guide AI precisely and efficiently is the key to getting the results you want. Today, I m sharing some of my favorite prompting tips, plus a handy cheatsheet I put together.

Prompting Tips That Actually Work

• Be spatially specific. Use keywords like "left", "right", "centered", "aligned to bottom", "spaced evenly" to help the model place elements correctly.

• Mention device behavior. If it should behave differently on mobile vs desktop, say so. Ex: "stacks on mobile, grid on desktop".

• Use visual vocabulary. Mention familiar UI terms like "modal", "toast", "card", "hero section", or "split view" to tap into known design structures.

• Give UX intent. Add the why: "Add white space for readability", "Add a hover effect for feedback", "Use a progress bar to show completion".

• Sequence your ideas. For complex prompts, list in steps: "First, add a header. Below that, place a form with two inputs...". AI loves structure.

• Say what not to do. If you want to avoid scrollbars, animations, shadows, etc., say so.

• Don t forget empty states. Great design considers what happens when nothing is there say "show a placeholder when list is empty".

• Test prompt variants. Swap words like "tile" vs "card", "modal" vs "popup" to see which gives cleaner structure.

• Use active voice. Start with a verb: "Add", "Place", "Make", "Create", "Animate", "Style". It helps guide generation.

I m growing a small SaaS. And cloud costs are starting to hurt. I keep hearing about founders stacking $100-300k in Google Cloud credits, but all the advice feels vague or locked behind big-name accelerators.
Where did you actually get credits?
Any creative hacks or things to avoid?
If you ve cracked this, I d love to hear what worked.

And if you re still figuring it out too, just drop a comment. If I ve gathered some useful stuff, I'll be happy to share.

Nice to see a Product Hunt advertiser do well!

Hey Product Hunt family!

Wanna hear your thoughts on tools for news feeds or news digest!

Welcome to the MLP era.

Let s talk about it:

hello, sina here, founder of integralhq.com. hope you're well.

i'm self publishing a small free book on building, growing and monetizing online communities. i've built lots of communities that have anything from hundreds to thousands of members (including a small paid founder community in asia), and i've always used the same set of actions/mental models for going from 0 to the first 20 active members and then more, and then retention, then the growth flywheel and monetization.

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 benefits for both users and makers or investors. Users don t have to install anything, updates are seamless, and their data is accessible from any device with a browser. For investors, the advantages are just as compelling: a single tech stack, easier user onboarding, lock-in effects, and plenty of levers for driving growth and virality.

Like most things, Loopify started out of frustration.

Cameron and I were just trying to find a simple way to post across multiple platforms but what we found were either outdated tools that felt like flip-phone era relics, or shiny ones charging premium prices for the bare minimum. Or both. So we started building what we wished existed. Something modern, clean, and actually pleasant to use.

Right now, we re in learning mode talking to creators, marketers, and small teams to understand what actually matters in a tool like this.

Curious to hear your thoughts:

and how i got hunters to back my launch

most people treat product hunt like a slot machine. pull the lever, hope for upvotes. but if you re launching anything serious, that s a waste.

We're seeing a huge influx of AI-powered tools, and it's exciting! But I'm starting to wonder if the rush to integrate AI into everything is leading to feature bloat and a more complicated user experience.

Are we sometimes sacrificing simplicity and intuitive design in the name of "AI-powered" functionality? Is every problem really best solved with AI, or are there situations where a simpler, more direct approach is actually better for the user?

Hey Product Hunt community!

I've been building some increasingly complex automations lately across different platforms (Make.com, n8n, Zapier) that connect multiple AI services together. While the technical side works beautifully, I'm hitting a major pain point: figuring out how much each automation actually costs to run.

This is a small test of your financial literacy and entrepreneurial mindset. :)

The art is mostly about making the most of the least, so share your approach to situations where you have to be creative.

Sound off in the comments or let me yell into the void.

Each of us leaves a digital footprint on the internet. The only difference is how much data and information we share publicly about ourselves.

For example, my local friend doesn't use his photo or name on his profiles so that no one will associate him too much with his income or political ideology.

I joined X last week as an effort to try out the whole founder led growth / build in public thing. At first it seemed exciting. There are a lot of very interesting people there and I find it easy to produce good enough content and be consistent with it. But a week in I haven t gotten a single follower, comment or like. The views on my posts are also super low. So yes, I m in that spot where I don t know what I don t know. Actually there is too much I don t know. So dear reader, if you have any tips or suggestions on how to get going (or simply why I should just drop the effort) they d be much appreciated, even if it s just sharing what s worked for you. Thanks in advance!

I ve been building AI wrappers for the past 3 years as an indie hacker. None of them became profitable. Building failed products taught me how to code, design and market properly. And one day all those skills paid out 

The idea

2 months ago Skype announced it was closing down. Most people used Skype for video calls, but there was a niche of people who used Skype to make cheap international calls to mobile and landline numbers. That was a golden opportunity major playing leaving the market, and its users scrambling for an alternative.

1. Effort results
I ve spent hours on posts that got 0 attention. I wrote my most viral post in 10 minutes while having morning coffee. You never know what will take off. Don't overthink it, just start writing and posting.
2. Don't be afraid to help competitors
Some people say building in public I only give my competitors an advantage. That's is partly true. At least 2 people reached out and said they built a similar product after my posts.
But first, this is great - the more the merrier, and the market is big enough for everybody.
Second, your real edge is not the tech you are using. It's the attention to the product you can generate. And social media is the only way to achieve it if you don't have millions for marketing.
3. Reddit hate is brutal
If your post has even a faint smell of promotion - people will hate you on Reddit. And when they do, they hate firecely. Expect a lot of angry DMs and downvotes.
4. Share your REAL struggles
The only way to avoid this and still get views, is being real. Share scary and cringy stuff. If you feel like you re gonna burn from shame after posting - it means you are posting the right thing.
5. Post on the right subs
Not all Reddit subs are equal. Most ban promotion posts. I always post on r/SideProject or r/SaaS. They are friendly to builders and your story will more likely resonate there.
6. Adjacent audiences rock
Some say builder subs are useless, because only your competitors hang out there. This is not true.
After my viral post on r/SaaS, I got a lot of leads for Yadaphone. Turned out many people on r/Saas and r/SideProject are freelancers, business owners and digital nomads. They all needed a cheap overseas call solution and I got a ton of new paying customers.
7. Not posting a link works
Avoid including a link to your product in Reddit posts. First, it s the quickest way to get banned for promotion. Second, if people like your product, they will google it, and it s a huge boost for SEO. Just share the name of the product in the post or wait until somebody asks for the link in the comments (somebody always does).
8. Non-native English is an advantage
This is a bonus for all non-native speakers out there. I used to push all my texts through ChatGPT to fix style and mistakes. And it only got me downvoted because people thought my texts were AI-generated.
Now I just write and post stuff as is. Making mistakes shows you are human, and Reddit values that over your perfect English
P.S. avoid the em dash at all costs, this is a clear sign you used AI (even if you didn t).
