before you scale.
The hardest calls come first: what to build, what to build it on, and whether anyone will pay. hewStack puts the evidence in front of you: what people pay for today, where a good free version is missing, and which healthy projects let you sell what you make.
Every idea looks good until you ask what people will pay for.

What hewStack solves for founders
The problem Build on the wrong project and you inherit its problems. Pick the wrong licence and you can't sell what you build.
A base you're allowed to sell on.
Say “I want to build and sell something on invoicing”. hewStack shows healthy projects whose licence lets you sell, how easy each is to start from, and what their users are already asking for: your first features.
- Safe at work, check licence or no licence, in one line
- Who's behind it, and whether it's still moving
- The most-requested missing feature, for each one
The problem Ideas are cheap. Knowing people already pay for the thing is what matters.
What people pay for, matched to free.
Today's paid launches, each matched to the free projects that do the same job, and how ready they are. Where it says no free match yet, people are paying and nobody has made the open version.
- Paid tools next to the free ones copying them
- The safest free version to switch to, marked
- The gaps, ready for a search to watch
The problem Markets warm up quietly. By the time it's in the news, it's crowded.
See which business jobs are warming up.
Every project is sorted by the job a business would hire it for: CRM, invoicing, booking, forms. Green columns are climbing. A job that's moving with nothing ready to recommend is an open goal.
- Rockets, waking giants and steady climbers, by job
- Unanswered jobs: demand with no good answer yet
- Tap any cell for the projects behind it
The problem Hundreds of options and no time to judge them all.
The best bases, ranked for you.
The Build-on score weighs what matters when you build to sell: demand rising, paid tools to undercut, a licence that lets you sell, a solid base, unmet asks, and room in the market.
- Start from one, with five behind it
- Compare any three side by side
- Ask in your own words, from any page
Three ways founders use it
From a hunch to evidence, in an afternoon.
“Where are people paying with no free option?”
- Open Paid vs free
- Look for no free match yet
- Check that job is warming in Business jobs
Proof people pay, and a gap nobody has filled.
“What's taking off in AI agents?”
- Ask “What's rising in AI agents this week?”
- Follow up: “only ones safe for a business”
- Watch it, and hear when a new one joins
You see the trend while it's still early.
