# How to Vibe Code Your Own Typefully (and Stop Paying for It)

> The AI-powered, collaborative social media scheduler

- Site: https://typefully.com
- Category: SaaS
- Platforms: Web app, macOS app
- Verdict: **Serious undertaking** (48/100 vibecodeable)
- Estimated effort: 4-6 weeks of part-time work

## Verdict

Build a personal subset for your own posting, but keep paying for the real product if you manage multi-client agency teams.

Replicating Typefully's clean editor and scheduling loop is achievable, but integrating 5 disparate social network APIs without hitting banned rate limits or payload validation errors is tedious. Furthermore, implementing team comments with exact text span anchor tags (<typ:comment-thread>) requires writing bulletproof CRDT or parsing logic that will test your patience during debugging.

### What you can't replicate

- Official enterprise rate limits and direct account rep access with social networks
- The exact fine-tuned voice model weights of their proprietary AI assistant
- An active user base of 10,000+ creators collaborating in real time

## What it does

A social media workspace, editor, and scheduling tool for creators and teams to write, collaborate on, preview, schedule, and cross-post across X, LinkedIn, Bluesky, Threads, and Mastodon.

### Core features

- Distraction-free split-screen text editor with character counters and thread splitting
- Pixel-specific live previews for X, LinkedIn, Threads, Bluesky, and Mastodon
- AI writing assistant ('Vesper') for voice-matched rewrites, expansions, and summaries
- Visual drag-and-drop content calendar and automated publishing queue
- Team commenting system with inline text anchor markers and @mentions
- Multi-platform OAuth account connection and token refresh manager
- Social analytics tracker for impressions, engagement rates, and follower growth
- Public API v2 and MCP server endpoints for programmatic draft creation and scheduling

## The business

### Pricing

- Free: $0/mo
- Pro: $10/mo
- Business: $20/mo

Founded 2020.
Team size: Small lean team.

## The hard parts

- Multi-platform API payload constraints, media upload limits, and strict rate-limiting rules across 5+ social networks
- Deterministic UI previews that accurately mirror how each network truncates text, folds links, and renders multi-image grids
- Complex collaborative comment threading with structural XML-like anchor markers in markdown text that survive parse-modify-patch round-trips
- Managing autonomous AI agent MCP server integrations and webhook event triggers securely without session leakage

## How to vibe code Typefully

### Prerequisites

- Node.js (free): Runtime for running Next.js and TypeScript services.
- GitHub (free): Version control and deployment pipeline source.
- Supabase account (free tier): Managed Postgres database with instant vector support and row-level security.

### Recommended AI tools

- Claude Code: Unmatched capability for scaffolding complex multi-file TypeScript logic, database schemas, and API connectors.
- Cursor: Ideal for fine-tuning split-screen preview components and keyboard shortcut event listeners.

### Stack

- Frontend: Next.js with Tailwind CSS and shadcn/ui
- Backend: Next.js Server Actions & API Routes
- Database: Supabase (PostgreSQL)
- Auth: better-auth
- Payments: none
- Other: Vercel AI SDK, Anthropic API, Resend

### Hosting

- Vercel (Hosting the Next.js frontend, server actions, and cron publishing workers.): $0/mo (Hobby Tier)
- Supabase (Hosting user tables, drafts, scheduled queues, and social auth tokens.): $0/mo (Free Tier)

### Build guide

1. **Project Scaffolding & Database Schema** — Initialize the Next.js application with TypeScript, Tailwind CSS, and shadcn/ui. Set up Supabase tables for users, social_sets, accounts, drafts, and scheduled_queue.

```
Initialize a new Next.js 16 project with Tailwind CSS 4, TypeScript, and App Router structure. Install Lucide icons and configure shadcn/ui primitives. Create a Supabase database client configuration file using environment variables (NEXT_PUBLIC_SUPABASE_URL and SUPABASE_SERVICE_ROLE_KEY). Write the SQL migration script for tables: users, social_sets (storing platform credentials and tokens securely), drafts (storing markdown text, thread segments, status enum ['draft', 'scheduled', 'published', 'error'], tags, and comment markers), scheduled_queue, and analytics_cache. Ensure proper foreign key constraints, indexes on updated_at and status, and strict TypeScript types matching the schema.
```

2. **Authentication & Social Account Linking** — Implement email and OAuth login using better-auth, alongside social set management pages.

```
Implement better-auth in the Next.js app supporting email/password authentication and Google OAuth. Build an onboarding and settings dashboard under /settings/social-sets where authenticated users can connect social accounts (X, LinkedIn, Bluesky, Threads, Mastodon). Store OAuth tokens encrypted in the database. Build API route wrappers to handle token refresh cycles and surface connection error states when tokens expire.
```

3. **Split-Screen Editor & Platform Previews** — Build the distraction-free split-screen editor with keyboard shortcuts, thread block splitting, and live simulated previews.

```
Build a high-performance split-screen editor page at /drafts/new and /drafts/[id]. The left pane features a markdown text editor supporting automatic paragraph-based thread splitting, character counters per platform limit (X: 280, LinkedIn: 3000, Threads: 500, Bluesky: 300), markdown bold/italic formatting persistence, and keyboard shortcuts (Cmd+Enter to publish/schedule). The right pane renders real-time pixel-perfect simulated previews for X, LinkedIn, Threads, and Bluesky, showing exact avatars, display names, media attachment boxes, and truncation folds dynamically.
```

4. **AI Writing Assistant & Voice Customization** — Integrate the Vercel AI SDK and Anthropic API to provide rewrite, expand, and punchier tone adjustments.

```
Create an AI writing assistant backend route using the Vercel AI SDK and Anthropic API (Claude 3.5 Sonnet). Build floating UI action buttons in the editor ('Make it punchier', 'Expand thoughts', 'Summarize', 'Rewrite in my voice'). Implement prompt templates that analyze the selected text block and stream suggestions back into the editor cursor position with smooth state transitions.
```

5. **Publishing Engine & Social API Integrations** — Build server-side publishing connectors for X API v2, LinkedIn, Bluesky, Threads, and Mastodon with robust error handling.

```
Build the publishing backend service in Next.js API routes that processes scheduled drafts or immediate publishes. Implement individual client adapters for X API v2 (handling media uploads via S3/Supabase storage and threaded tweet creation), LinkedIn API (handling organization urn resolution and post payloads), Bluesky (AT Protocol session and record creation), Threads, and Mastodon. Implement robust rate-limit header parsing (429 detection, retry-backoff logic) and error logging to flag failed posts in the database queue.
```

6. **Content Calendar, Queue, and Analytics Dashboard** — Implement the drag-and-drop content calendar, automated queue scheduler, and X analytics performance view.

```
Build a visual calendar and queue management view at /calendar using a grid component. Allow users to drag drafts across dates or assign them to automated queue slots. Build an analytics page at /analytics that queries X API v2 performance endpoints for impressions, likes, retweets, comments, and follower series data, rendering interactive charts using Recharts with date range pickers (up to 366 days).
```

### Cost vs paying
