IG Autoposter
A SaaS that writes, illustrates, schedules, and publishes Instagram content on its own.
Small businesses die on Instagram because consistency is a full-time job. This automates the whole loop: generate, schedule, publish.
Connect an Instagram account and the system generates captions and images with AI, queues them on a schedule, and publishes via the Instagram Graph API on cron — with drafts, review, and subscription billing built in. Instagram connection is currently invite-only while the Meta app review is in progress; you can sign up and explore the generation and scheduling flow today.
Architecture
Next.js App Router on Vercel; Prisma over Postgres with Supabase auth; Stripe subscriptions; AI image generation via Replicate with Sharp for post-processing. Cron routes drive scheduled publishing through the Meta Graph API, with token refresh handled server-side.
Production posture
This is a real multi-tenant SaaS, not a script with a UI: per-user Instagram credentials and tokens live server-side with automated refresh (Meta tokens expire on a ~60-day cycle), publishing runs on cron against the Graph API with retry handling, and billing is enforced through Stripe subscription state. The codebase carries a Vitest unit suite, Playwright end-to-end tests, and Sentry error tracking — failures in the publish path surface loudly instead of dropping posts silently.
