How to vibe codeposterly
The AI-powered social media scheduler for creators and teams.

The verdict: can you vibe code posterly?
Build a personal dashboard and local scheduler subset yourself, but keep paying for the service if you rely on 18 fully maintained social platform APIs.
The dashboard, calendar UI, and AI caption wrappers are straightforward to construct with modern AI coding tools. However, the true nightmare of a social scheduler is the relentless maintenance overhead of OAuth token refreshes, shifting API schemas across 18 networks, and configuring bulletproof asynchronous queues. For $15/mo, paying for the service spares you from endless API deprecation debugging.
Estimated effort: 2-3 months of focused part-time work
What you can't replicate
- Zero-maintenance OAuth connections across 18 third-party social networks
- Built-in partnership access to proprietary platform posting permissions
- Instant agency client trust and review history

The hard parts of vibe coding posterly
- Maintaining OAuth authentication tokens, rate limits, and changing API payloads across 18 distinct social platforms
- Implementing rock-solid asynchronous queueing with Redis and BullMQ to prevent dropped posts or double-publishing
- Building a secure Model Context Protocol (MCP) server enabling external AI agents to execute write operations programmatically
- Handling media conversions and aspect ratio adjustments for various video and image requirements per network

Build guide
01Project Scaffolding and Database Schema
Initialize the Next.js application with TypeScript, Tailwind CSS, and configure Turso with better-auth tables and core relational models for brands, social accounts, posts, and scheduled queues.
Scialize a new Next.js project using Tailwind CSS and configure better-auth with Turso as the database. Create Prisma or Drizzle schema definitions for users, workspaces, connected_accounts (storing encrypted OAuth tokens), posts (with fields for title, content, media URLs, status, scheduled_at, and platform targets), and client_approvals. Ensure all foreign keys have proper cascading deletes and indexes on scheduled timestamps for fast queue polling.02Unified Dashboard and Calendar UI
Build the core command center featuring monthly, weekly, and list views for scheduled posts using drag-and-drop scheduling components.
Build a responsive Next.js dashboard layout with a collapsible sidebar and top nav. Implement a main content calendar view supporting month, week, and list filters. Use React components to display scheduled post cards color-coded by social platform icon (Instagram, X, LinkedIn, TikTok). Include quick action buttons for creating new posts, filtering by brand workspace, and viewing summary analytics counters for scheduled and published counts.03Multi-Platform Composer and AI Brand Voice
Construct the content composer supporting multi-platform targeting, character limit validations, and AI-assisted caption generation.
Create a multi-platform post composer component. It should allow selecting multiple target social accounts, provide a unified text area with live character limit indicators per network, and support media uploads. Integrate the Vercel AI SDK to add an 'AI Brand Voice' button that calls an API route, passing recent post history from Turso to generate an on-brand caption variant with American or British spelling rules.04Asynchronous Queueing and Scheduler Engine
Set up Redis and BullMQ on Railway to manage exact-minute post publishing with idempotent retry loops and error logging.
Configure a BullMQ worker backend running on Node.js connected to a Railway Redis instance. Implement a cron-style job producer that polls Turso for posts where scheduled_at <= NOW() and status = 'scheduled'. Create worker tasks that process posting payloads to simulated or real social APIs, handling rate limits with exponential backoff retries, setting status to 'published' on success, or capturing error logs and updating status to 'failed' if all retries exhaust.05Model Context Protocol (MCP) Server
Expose an authenticated Model Context Protocol (MCP) server so external AI coding assistants can query accounts and schedule posts programmatically.
Build an MCP (Model Context Protocol) server endpoint within the Next.js application using standard transport layers. Expose tools that allow authenticated external agents (like Claude Desktop or Cursor) to list connected social accounts, retrieve recent post analytics, and programmatically schedule new posts. Secure the endpoints with Bearer token authentication validated against workspace API keys.06Client Approval Workflows and Polish
Develop the white-label review portal enabling external clients to verify via email code and sign off on posts without a paid seat.
Implement a client approval portal accessible via secure tokenized links. When an agency sends posts for review, generate a guest view where the client enters their email, verifies via a 6-digit code sent via Resend, and views posts in a feed or calendar format. Add interactive controls for 'Approve', 'Request Changes', and 'Comment' that update the post status in Turso and trigger notification logs for the agency team.

Vibe code posterly: FAQ
- Can you vibe code posterly yourself?
- Serious undertaking — 38/100 vibecodeable. Build a personal dashboard and local scheduler subset yourself, but keep paying for the service if you rely on 18 fully maintained social platform APIs.
- How long does it take to vibe code posterly?
- 2-3 months of focused part-time work — roughly 45-60 hours of hands-on time with an AI coding agent.
- How do you build your own posterly?
- Scoped to personal use: Next.js on the front, Next.js API routes with Redis worker queues behind it, Turso for data. Follow the 6-step build guide on this page — each step has a paste-ready prompt for an AI coding agent.
- How do you code your own posterly without being an expert?
- Use an AI coding tool (Claude Code or Cursor) and work in small steps: scaffold, data model, core screens, then deploy. Realistic effort: 2-3 months of focused part-time work. The prompts on this page are written so the AI does the heavy lifting.
- How much does it cost to vibe code posterly instead of paying?
- About ~$32 one-time to start and ~$10-25/mo to run, versus $15/mo for posterly. Break-even: Never (paying $15/mo is cheaper than the maintenance and infrastructure time).
- What stack should you use to vibe code posterly?
