Context

**Later** — Visual social scheduling, link-in-bio, and creator marketing tools. It currently costs $25/mo.

A post calendar and queue are buildable, but Later's value is social API access, visual planning, link-in-bio, analytics, media library, and platform compliance.

This brief describes a focused, single-operator replacement for the part of Later that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.

What you are building

Build a content calendar, schedule posts through social APIs, store media, and track publish status.

Draft, queue, and track content for the few networks you actually use.

A responsive interface with real empty, loading, success, and error states.

Requirements

Functional

Hosted scheduler.

Media storage.

Database.

Retry and logging.

Data and integrations

OAuth/API access.

Each of these needs a real account, credential, or quota. Set them up before writing feature code.

Non-functional

Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.

Security: server-side secrets, validated input, and no credentials in the client bundle.

Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.

Portability: the operator can export their data and leave without losing it.

Implementation brief

Build me a personal social post scheduler to replace Later. Requirements:

Node + Express + better-sqlite3 on localhost:4870. Posts table: text, media

paths, platform, scheduled time, status (queued/posted/failed).

A month-grid calendar page plus a queue list; compose form with image preview and

a per-platform character counter. Media files live in a media/ folder.

node-cron checks the queue every minute and publishes via official APIs where

they are sane: Bluesky and Mastodon first (tokens in .env). Add X only if my API

tier allows posting, check before building it.

For Instagram, do not fight the API: at post time send me an ntfy.sh push with

the caption and image path so I can post by hand in twenty seconds.

Failed posts retry twice, then flag red on the calendar with the API error saved.

Published posts store the live URL so the calendar links to the real post.

Single user, binds to localhost only, no accounts, no telemetry.

Out of scope: analytics, link-in-bio pages, and approval workflows.

README: per-platform token setup, plus an honest note that social APIs drift and

this needs occasional patching, that upkeep is what Later was charging for.

Delivery standard

Inspect the repository first, then write a short implementation plan before writing code.

Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.

Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.

Include responsive layouts plus genuine empty, loading, success, validation, and failure states.

Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.

Add structured logs around every external call and return actionable errors without leaking sensitive details.

Write unit tests for the core logic and one automated test of the main user journey.

Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.

Acceptance criteria

A clean install starts the app using only the README and .env.example.

The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.

Invalid input, missing configuration, provider failure, and an empty database each have a usable state.

The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.

Tests, type checking, linting, and a production build all pass with no ignored failures.

No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.

Non-goals

Do not build these, and do not claim to have replaced them:

Visual planner.

Social API maintenance.

Link-in-bio.

Analytics.

Connectors, OAuth flows, and vendor API changes require constant upkeep.

The last 20 percent is sync, migration fidelity, speed, and edge cases.

What you still own after launch

Secure credentials, rotate secrets, and handle provider rate limits.

Run migrations, backups, restores, and dependency updates.

Test the critical journey after every model, API, or hosting change.

Monitor failures and fix the edge cases a first prompt will miss.

Maintain every third-party integration as APIs and OAuth rules change.

Risk

**Operational risk.** The code is achievable; dependable data, integrations, and ongoing operations are the real cost.

Editorial confidence in this assessment: medium. No independent one-shot implementation is linked yet.

Prior art
