TeamKit

What it does

Most SaaS boilerplates give you auth and billing — then leave you to build multi-tenant teams from scratch. TeamKit ships with everything wired up: • Multi-tenant teams — create, invite by link, role-based access • Supabase RLS—row-level security scoped to team membership • Owner-pays billing—one Pro plan covers the whole team • Stripe subscriptions+Customer Portal • Next.js App Router, TypeScript strict, Tailwind CSS 4 • English & Japanese UI $79 one-time. No seat fees. Unlimited projects.

The Next.js boilerplate with real team features built-in

Auth, billing, multi-tenant teams, RLS, and real-time — all wired up. You buy a starter kit, wire up Stripe, then spend weeks building invite flows, RLS policies, and the "owner pays, team gets Pro" billing model. TeamKit ships with all of that working on day one. Multi-tenant teams with invite links, roles (owner/admin/member), and member limits built in from day one. Row Level Security policies are production-ready. Every table is scoped to team membership — no data leaks. Supabase Realtime is wired up. Extend the pattern for live updates across your team workspace. Full source code. No recurring fees for the boilerplate itself. Charged as ¥11,800 at checkout (Lemon Squeezy). Your bank…from teamkit-sales.vercel.app

  ReadyKit – Superfast SaaS Starter with Multi-Tenant WorkspacesNov 2025 · readykit.dev · ▲121

  Hi HN! I've been building ReadyKit, an open-source SaaS boilerplate that handles all the hard parts: multi-tenant workspaces, Stripe billing, OAuth + MFA authentication, and a production-ready stack. Built with Python/Flask, PostgreSQL, Redis, and Vue 3, it's designed for indie makers and teams who want to ship SaaS products fast. Clone, configure your OAuth and Stripe keys, and you're running in 5 minutes. Features include automatic query scoping for workspace isolation, audit logs, role-based access, and a modern UX kit. MIT licensed and free forever. GitHub:…

  Indie Kit2025 · indiekit.pro · ▲58

  I wanted to build simple apps to launch over the weekend. I was so frustrated implementing billing, stripe, auth, quota management, etc. I just gave up. So I made Indie Kit Login users, process payments, send emails at lightspeed. Spend your time building your startup, not integrating APIs. Indie Kit provides you with the boilerplate code you need to launch, FASTER THAN EVER.

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
