The verdict: can you vibe code Circle?
Build a modular community and course workspace clone for personal use, but drop the enterprise mobile app wrapping, email hub, and native billing tiers.
Building a personal clone of Circle's core loop—spaces, discussions, direct messaging, and course modules—is a solid side project for a full-stack AI coding agent. However, replicating an all-in-one platform means juggling multiple distinct domains: a forum, a chat system, a video player course interface, and a role-based access control system. The hardest part isn't any single feature, but cleanly wiring up the relational access matrix so that buying or joining a space instantly unlocks the right channels and course modules without permission leaks.
Estimated effort: 3-4 weeks of focused development

Build guide
01Project Scaffolding & Database Schema
Initialize the Next.js 16 app with Tailwind CSS and configure the core relational database schema in Supabase for communities, spaces, posts, comments, and members.
Create a new Next.js 16 project with Tailwind CSS, TypeScript, and App Router structure. Configure Supabase client utilities for browser and server operations. Write a complete PostgreSQL migration script for a community platform with tables: `communities`, `spaces` (linked to community with type: discussion, chat, course, events), `profiles`, `posts` (with title, content, space_id, author_id), `comments`, and `space_memberships` (for access control). Ensure foreign keys have cascading deletes and proper indexing on foreign key columns.02Authentication & Member Profiles
Implement Supabase Auth with email/password login and automatic profile record creation upon sign up.
Implement Supabase Auth sign-in and sign-up flows with a clean, modern auth page styled using Tailwind CSS and shadcn/ui components. Create a database trigger that automatically provisions a row in the `profiles` table whenever a new user signs up in `auth.users`. Build an authenticated layout with a navigation sidebar showing the user's avatar, display name, and settings link. Protect all community routes so unauthenticated visitors are redirected to the login page.03Spaces & Modular Feed Implementation
Build the core community space layout with dynamic space switching and a rich-text discussion feed.
Build a community space navigation sidebar that lists spaces grouped by category (e.g. Discussions, Chat, Courses). Clicking a space should load its dedicated view. For 'discussion' spaces, implement a feed view showing posts with author avatars, timestamps, and vote/comment counters. Include a post creation modal with rich text support or Markdown preview. Ensure posts can be filtered by tags or sorting options (latest, top, active).04Real-time Chat Spaces
Add real-time messaging support inside chat-type spaces using Supabase Realtime subscriptions.
Implement a real-time group chat interface for spaces marked with type 'chat'. Use Supabase Realtime channels to broadcast and listen to new messages instantly without requiring page reloads. The chat view should feature a scrollable message history list with grouping by sender and day, an auto-scrolling bottom anchor for new messages, and an input bar with emoji support and enter-to-send functionality.05Course Builder & Lesson Viewer
Build a structured course module space with a sidebar lesson navigator and video embedding.
Create a course viewer layout for spaces of type 'course'. The layout must feature a left sidebar showing course modules and nested lessons with completion checkmarks, and a main content area rendering lesson details, markdown text, and embedded video players (YouTube or Vimeo iframe support). Add a 'Mark as Complete' server action that updates user progress and visually reflects the updated state in the module tree.06Member Directory & Access Control
Build a searchable member directory and enforce space-level access control permissions.
Implement a searchable member directory page displaying user profiles, roles (admin, moderator, member), and join dates with instant search filtering. Create a robust access control middleware or server helper function that checks if a user has an active membership record in `space_memberships` before granting access to private spaces or course content. Return a clean 'Access Denied / Upgrade Required' state if permissions fail.
