MantleKit is here - The Stack I Got Sick of Rebuilding;
05/04/2026
MantleKit is my all-in-one Next.js SaaS starter kit—auth, payments, blog, ecommerce, admin dashboard, and 10+ themes ready to go so you can ship faster.
There’s a point in every project where you realise…
You’re not building your product.
You’re rebuilding the same scaffolding you’ve already built ten times.
Auth. Payments. Blog. Emails. Dashboard. SEO. Pages. Config.
Every. Single. Time.
So I stopped doing that.
I built it once.
Properly.
And that’s what MantleKit is.
What MantleKit actually is
MantleKit is my full SaaS foundation built on Next.js + TypeScript.
Not a half-finished starter repo. Not a “good luck, wire it up yourself” template.
A complete system that already has:
- 🔐 Authentication (ready to go)
- 💳 Payments (Stripe / Lemon Squeezy / Polar)
- 📝 MDX Blog system
- 🛒 Ecommerce support
- 📊 Full backend dashboard
- 📬 Email + forms
- ❓ Support + knowledge base
- 🧩 CMS-style content management
- 🎨 10+ themes (and growing)
You install it… and you’re already past the boring part.
Why I built this
Because I got sick of wasting time.
Not in a dramatic way. Just… repeatedly losing days to stuff that adds zero competitive advantage.
Nobody wins because you spent 6 hours wiring auth again.
Nobody cares that your Stripe webhook works.
That’s not the product.
That’s just the barrier before the product.
MantleKit removes that barrier.
The real value isn’t the features
It’s the starting position.
Instead of:
idea → setup hell → burnout → maybe launch
You start here:
idea → product → launch
That’s the difference.
Everything is already structured in a way that makes sense:
- marketing pages
- app routes
- blog
- dashboard
- API
- config
So you’re not fighting your own codebase two weeks in.
The dashboard is where it actually hits different
This is the part I wanted the most.
Not just a frontend template… but a real backend system.
MantleKit includes a proper dashboard where you can manage:
- content
- users
- products
- support
- emails
- media
It turns your project from:
“a website”
into:
an actual product
Themes that don’t suck
I didn’t want one theme.
I didn’t want five slightly different versions of the same thing.
MantleKit ships with 10+ proper themes, and they’re designed to actually feel different — not just a colour swap.
Because realistically:
- first impressions matter
- landing pages matter
- conversion matters
And spending days tweaking Tailwind just to get something “good enough” is a waste.
Pick a theme. Ship.
Built for how I actually work
This wasn’t built in theory.
It was built out of:
- real projects
- real frustrations
- real “why am I doing this again?” moments
So everything in MantleKit is there because I’ve needed it before.
Not because it looks good on a feature list.
Who this is for
If you:
- build SaaS products
- launch ideas regularly
- do client work
- hate rebuilding the same stack
This is for you.
If you love wiring everything from scratch every time…
You’re probably not the target 😄
What this means going forward
For me, this changes how I build.
Every new idea now starts from:
MantleKit → customise → launch
Not:
blank repo → suffer → maybe finish
That’s a massive shift.
Final thoughts
This isn’t trying to be everything.
It’s trying to remove the part of building that shouldn’t exist anymore.
The repetitive setup. The wasted time. The friction before momentum.
MantleKit gives you a clean, fast starting point…
So you can focus on the part that actually matters:
building something worth launching

This one’s a big one for me.
And yeah… I’m just getting started.
