Northstack is a full-stack SaaS starter in a Bauhaus style: a Next.js website that sells your product with a real license checkout, a Next.js workspace dashboard with projects, teams, roles, billing and an AI assistant, a platform administration for the people who run the service, and a NestJS API behind all of them. English and Arabic with RTL, in light and dark.

The package

The hard parts of a SaaS, connected

A connected foundation for your own SaaS, a client's product or an internal tool, with source code you can customize. The full-stack package includes the website, the dashboard and the API behind them, and each frontend also runs alone on built-in sample data.

SaaS website

  • Home, pricing and documentation
  • A license checkout with Stripe, PayPal or a test checkout
  • A journal, a changelog and a contact form
  • Runs alone on sample data with no API

Workspace dashboard

  • Sign-up, onboarding and invitations
  • Projects with task boards, files and activity
  • Roles, billing, settings and API keys
  • The AI assistant and the platform administration

NestJS API

  • Accounts, workspaces and four workspace roles
  • Billing with Stripe or a built-in simulator
  • License orders with Stripe and PayPal
  • A seeder with two full workspaces and 732 organizations
The workspace's day

An overview of the work and the account

The overview opens on the workspace's projects, open and completed, this month's API requests and seats against the plan, the week's task activity by day, a launch checklist, the projects that need attention and the latest activity, over the last 7, 30 or 90 days.

AI assistant

An assistant that proposes, and you apply

The assistant answers from the workspace's own data through twelve read-only tools, within the reader's permissions, on Google Gemini, OpenAI or DeepSeek. It never changes the workspace by itself: a change arrives as a card that a member applies or dismisses.

Changes you confirm

Ask what is due this week or for a launch checklist, and the assistant drafts the tasks as a proposal with Apply and Dismiss. Applying checks the member's access again and creates the tasks once.

  • Charts and tables of projects, tasks and usage
  • Follow-up questions after every answer
  • Conversations saved with their history
  • Each person can add their own key, kept in their browser
  • The same tools open to coding agents at the MCP endpoint

Teams and roles

Four roles, one matrix the owner edits

A permission matrix per workspace

Owner, admin, member and billing come seeded across fourteen permissions in six groups. The owner grants or removes any of them, and the API reads the matrix again on every request.

  • Owner-only rights that stay with the owner
  • Every change written to the activity log
  • The same checks in the dashboard and the API

Members, invitations and seats

Invite by email with a role, resend or revoke, change a member's role, remove a member or transfer ownership, with the seats left on the plan always in view.

  • Invitation links that expire
  • Seats counted against the plan
  • An accept page for invited people
Team members and invitations, light theme

Projects

Projects with boards, files and a history

Projects carry a status, an owner, a due date and progress from their tasks, in English and Arabic, with tabs, search, status, owner and due-date filters and paging. Each one opens on a board of Backlog, In progress, Review and Done, with priorities, assignees and due dates, beside its files and its own activity.

Billing

Plans, usage and invoices, with Stripe or without

Change plan from the billing page

Starter, Pro and Scale come with their seats, API requests and storage. An upgrade opens Stripe's hosted Checkout, or the built-in test checkout when no Stripe key is set; a downgrade is scheduled for renewal, and the billing page confirms a payment before it shows the new plan.

  • Usage against each limit
  • Invoices as PDF downloads
  • Cancel at period end and resume
  • A grace period for past-due payments

Settings and API keys

The workspace's name, address, language, time zone, domain and notifications, and API keys shown once at creation and revoked in one click.

  • Keys with scopes and an environment
  • Email and weekly digest switches
  • A danger zone to delete the workspace

An activity log you can export

Every change is written to the audit log with who did it and when, filtered by type, person and dates, searched, and exported to CSV.

  • Sentences built in the reader's language
  • Notifications in the bell
  • A search palette for projects, tasks and members

Platform administration

Run the service, not only one workspace

Platform staff get their own area: monthly recurring revenue and the plan mix over 30 days to 12 months, the paid, trialing, past-due and suspended workspaces, and every organization with its plan, seats and status.

Every organization in one list

Search and filter the seeded 732 organizations by plan and status, and suspend or reactivate one with a reason. A suspended workspace keeps read access and refuses every write.

  • Users with soft delete and restore
  • Staff with the Platform admin and Support roles
  • App settings and a revenue report as CSV

Each organization's record

An organization opens on its owner and members, its usage, its invoices, its subscription history and the platform's own events about it, such as a suspension and its reason.

  • Invoices and plan changes
  • Suspensions written to the audit log
  • Platform roles edited permission by permission

The website

A website that sells the product

Pricing offers two one-time source-code licenses, and each one leads to the site's own checkout: the buyer gives an email and a name, chooses card or PayPal, and pays on Stripe's or PayPal's own page. The server confirms the payment before the receipt shows the license key, and without keys both methods go through a test checkout.

Documentation with a table of contents

Ten articles, from the introduction and the quick start to roles, billing and the production checklist, with steps, tables and code, in both languages.

  • Anchored headings and a table of contents
  • Code blocks that copy
  • A search across the articles and a link to the next one

The website

A journal and a changelog

Seven journal articles with categories and search, and a changelog with every release, so the site has something to say on its first day.

A contact form with topics

Visitors choose a topic and write a message, checked field by field, and the API keeps every message and forwards it to your inbox when one is set.

  • A hidden field that stops bots
  • A limit per address

Bilingual

English and Arabic, in both directions

Every screen of the website and the dashboard is written in both languages and mirrors for Arabic, with an Arabic type stack. Projects and tasks are stored with their text in both, and figures stay in Latin digits.

Responsive

Made for a phone as well as a desk

The website and the dashboard fit a narrow screen: the menus fold into drawers, tables become lists, and a project's board scrolls sideways.

Sample data

Each frontend also runs on its own

Bought alone, the website or the dashboard opens as a working product: with no API address set, every request is answered in the browser from sample data exported from the seeded API, and a notice says so. Set the address and the same build talks to the API; one command removes the sample data for good.

Try the demo

A demo account for every visitor

The dashboard demo's sign-in gives each visitor an account of their own with the role they pick, and the assistant answers five messages for free. The seeded data is shared and stays as it is, what a visitor creates is theirs alone, payments are test payments only, and the demo resets every night.

What you get

Everything to run it, not only the screens
