I've started to notice something about mature products.

The size of a feature rarely determines how much work it takes.

Instead, the effort depends on how many past decisions that feature touches.

A simple "Add Google Login" suddenly affects authentication, onboarding, permissions, analytics, documentation, QA, and maybe even your pricing model. What looked like a two-hour task turns into a week of discussions because you're no longer building a feature; you're negotiating with decisions your product has accumulated over months or years.

Hello Product Hunt community!

I'm Martin F rst, founder of TradeScalpPRO, a trading assistant currently in Google Play closed testing.

Hey everyone!

If you re building a SaaS or a side-project, setting up payments usually means hours of dealing with webhook routing, customer sync logic, and getting locked into one provider.

I built Paycan to fix this. It s an open-source, self-hosted checkout layer.

• No Vendor Lock-in: Switch between Stripe and PayPal without changing your database or application logic (more local payment providers soon).

• Drop-in Simple: Around 10 lines of code to integrate.

• Self-Hosted & AGPLv3: You run it on your own server, keeping full control over your checkout.

We re building an AI-first way to search and discover flights focused on simplifying decisions, not overwhelming you with options.

But here s the truth: This is still early.

Plavtora is an AI second opinion for founders.

Before you spend weeks building, launching, or marketing something, Plavtora helps you pressure-test the decisions behind it.

Analyze your:

• Startup & launch readiness

• Ideal customer profile

• Landing page

• Risks and weak points

• Positioning and messaging

I m building LifeOS, an iPhone app for people whose days often change unexpectedly.

LifeOS helps you:

• capture responsibilities quickly

• reserve time when it matters

• see what matters now and next

• recover calmly when something does not happen

• use a widget to stay oriented without constantly opening the app

It is an early beta, and I m looking for 10 20 iPhone users who:

Every trip planner I tried either dumped a checklist that ignored geography, or handed me a "finished" plan I had no say in. Built Routinex to fix that: neighborhood-anchored days, group voting, live weather/flight data, and a Cruise Port mode for people who stress about all-aboard timing.

routinex.travel

What's the one trip-planning problem you still haven't found a good tool for?

Almost all of the Travel platforms are the same in common, they show you bookings,hotels, etc. But they don't show how real discovering the world is. The thing they don't offer is sharing best places form by users through memories. Start exploring and share your memories, https://velormo.netlify.app, btw I am a solo founder, and welcome to Velormo, hope this Platform help you.

Hey Product Hunt community!
