Stop wiring plumbing.
Start building your product.

Every SaaS needs the same six systems before it can take a paying customer. Build them yourself and lose weeks — or start today with all six already done, tested and wired together.

/ what's inside

The parts every SaaS
needs, not another boilerplate.

Standard Next.js, Supabase and Stripe — wired the way a senior team would, not glued together with abandoned packages. Read the code in an afternoon and you'll understand all of it.

FLAGSHIP

One customer can never see another's data

Multi-tenancy is enforced inside Postgres itself, not hoped for in your API code. Even a bug in a route you write can't leak one customer's data into another customer's account — the database blocks it before your code runs.

Per-tenant isolationOwner / Admin / MemberEvery table covered
-- supabase/policies/projects.sql
create policy "tenant_isolation"
on projects for select
using (
org_id = auth.org_id()
);
✓ 32 tables · RLS enforced

Every customer gets their own space

The moment someone signs up, they get a private workspace — no setup script, no manual step, nothing for you to wire up by hand.

orgs · workspaces

Your customers manage their own team

Owners invite teammates, admins manage settings, members just get work done. The permission logic behind all of it is already written and wired to the database.

owner · admin · member

No stranger sneaks into an account

Invite links expire after 7 days, work once, and can’t be guessed or replayed — invite security you never have to think about.

7-day expiry · single-use
$

Your customers pay you, automatically

Checkout, receipts, upgrades and failed-payment retries — the billing edge cases people usually discover the hard way, in production, are already handled.

checkout · webhooks

Bots get blocked before they start

Your login and sign-up pages are protected from brute-force attempts and spam sign-ups from day one — no extra service to configure.

brute-force · spam guard

Emails that actually land in the inbox

Confirmation and invite emails are delivered reliably, and your sender reputation stays clean — you don’t have to think about deliverability.

resend · bounce handling
/ and the finishing touches

Profile & Account

Avatar uploads, account settings, and the small polish that makes a product feel finished — not a project.

§

Privacy Policy Included

A pre-written, editable privacy policy. Add your business name and email, and the legal basics are covered.

Typed Postgres, No ORM

Plain SQL with full TypeScript types. Rename a column and the compiler shows you every place to fix it — no ORM standing between you and your database.

/ security

Built for developers
who sell to real businesses.

Selling to companies means answering security questions eventually — usually right when you're trying to close your first big deal. Get ahead of it now instead of scrambling later.

Security audit

Scale

Someone actually reads through your code looking for common mistakes — not just an automated scanner with your name stamped on the report.

Dependency scan

Scale

We check every package you depend on against known vulnerabilities, so you’re not shipping someone else’s bug without knowing it.

Authentication review

Scale

A second pair of eyes on your login, sessions and password resets — the exact spots where small mistakes turn into real breaches.

API review

Enterprise Ready

We look at how your API handles input, auth and errors, and flag the first things an attacker would try.

OWASP checks

Enterprise Ready

Your app gets checked against the standard list of common web vulnerabilities — the same list most auditors start from.

Multi-tenant isolation review

Enterprise Ready

We double-check that one customer truly can’t reach another customer’s data, beyond what the database already enforces.

Permission review

Enterprise Ready

We verify that roles and permissions actually restrict what they’re supposed to — not just in the code comments.

GRC readiness report

Enterprise Ready

A plain-English summary of where you stand on governance, risk and compliance — handy the first time a customer’s legal team asks.

SOC 2 checklist

Enterprise Ready

What SOC 2 actually requires, mapped to what you already have and what’s still missing — before you pay an auditor to tell you.

GDPR checklist

Enterprise Ready

The practical GDPR basics — data requests, deletion, consent — explained without the legal jargon.

ISO 27001 checklist

Enterprise Ready

A readiness checklist so an ISO 27001 conversation doesn’t catch you off guard.

/ velocity

From git clone to production in an afternoon.

The unglamorous months of plumbing — auth flows, webhook retries, permissions, transactional email — are already tested and shipping. You start at the part only you can build: your actual product.

/ community

You're not shipping alone.

Building a SaaS solo is lonely. Our Discord is other builders doing the same thing — not a ghost town.

Ask other builders

Stuck on an RLS policy or a webhook bug? Ask people who’ve actually hit the same wall.

Share what you’re building

Post your progress, get real feedback, and find your first users before you launch.

Learn from production founders

See how people running real SaaS businesses actually made their decisions — not just theory.

Vote on what we build next

Scale

Tell us which modules and features matter most, and we build those first.

Early access to new modules

Scale

Try new modules before they’re released to everyone else.

Monthly office hours

Scale

A live call, once a month, to ask questions directly — no ticket queue.

/ what you’re really buying

No hype. Just the work
you'd have to do anyway.

The security is written, not left as a TODO

Row-level isolation on every table, roles that actually restrict access, and invitations that can’t be guessed — the parts that are easy to get subtly wrong are already done and tested.

One customer can’t read another’s data

Isolation lives inside Postgres itself, so a bug in your own code can’t leak one customer’s data into another customer’s account.

Billing that survives the edge cases

Checkout, customer portal and webhook handling — including the retries and out-of-order events people usually only discover after they’ve already launched.

Typed end to end, no ORM to fight

Plain SQL with full TypeScript types. Rename a column and the compiler shows you every place to fix — no black box between you and Postgres.

Auth you don’t have to think about

Supabase auth with Google one-tap and magic links, plus rate-limited login and sign-up so brute-force and spam bots are handled from day one.

It reads like you wrote it

Standard Next.js, Supabase and Stripe, wired the way a senior team would — no abandoned wrappers, no magic to reverse-engineer at 2am.
