How I Built a Self-Hosted PayPal & Stripe Checkout (and Why I Avoided Middlemen)

Hong Phat Ly — Sun, 28 Dec 2025 17:43:15 +0000

Accepting payments should be easy.

Yet every time I started a new side project or SaaS, I found myself stuck choosing between:

Copy-pasting PayPal buttons from outdated docs
Wrestling with Stripe Checkout flows I didn’t fully control
Or using hosted tools that added fees, lock-in, or abstraction I didn’t need

I wanted something simpler:
👉 a small, self-hosted layer that turns a snippet into a real PayPal or Stripe payment button
No middleman. No platform lock-in. My keys, my server, my funds.
So I built one.

The problem with “just use Stripe / PayPal”

Don’t get me wrong — Stripe and PayPal are great payment processors.
The problem isn’t them.
It’s everything around them.
Common issues I kept hitting:

Too much boilerplate for simple payments
Different flows for PayPal vs Stripe
Hosted tools that:
- take a cut
- store transaction data
- break when pricing changes
Little control over UI and behavior For many projects, I just wanted:
A button
A price
A callback
Done

What I wanted instead

My requirements were simple:

✅ Self-hosted
✅ Works with my own PayPal & Stripe API keys
✅ No transaction fees
✅ Simple embed snippet
✅ Optional cloud version for people who don’t want to host That was the idea behind what eventually became FreshLimePay.

How it works (high level)

The core idea is intentionally boring (on purpose):

You connect your PayPal or Stripe keys
You define a product or amount
The system generates a small snippet
That snippet renders a real checkout button
Payment goes directly to your account No proxying money. No holding funds. No “platform wallet”.

Example: from snippet to button

The goal was something like this:

PayPal:

Stripe:

And you instantly get a working payment button.
That’s it.

Self-Hosted vs Cloud (why I support both)

While building this, I realized something important:
Not everyone wants to self-host.

So FreshLimePay ended up with two modes:
🔒 Self-Hosted

Install on your own server
Full control
One-time or yearly license
Best for developers, agencies, SaaS founders

☁️ Cloud

No installation
Instant setup
Subscription
Best for non-technical users or quick launches

Same idea. Same philosophy.
Different levels of control.

Why self-hosting still matters (for some of us)

Self-hosting isn’t about nostalgia.
It’s about:

Ownership
Predictable costs
Fewer dependencies
Sleeping better when pricing pages change elsewhere 😅

If you’re a developer, you probably know the feeling.

If you don’t want to build this yourself

I ended up packaging this into FreshLimePay so others wouldn’t have to rebuild the same thing again and again.

Website: https://freshlimepay.com
Cloud app: https://cloud.freshlimepay.com

If you do want to build your own — great.
If you don’t, this might save you some time.

Final thoughts

This isn’t meant to replace Stripe or PayPal.

It’s meant to make them simpler to use, especially for small products, MVPs, and indie projects.

If you’re interested, I’m happy to answer questions or share more implementation details in the comments.
