📆 Queue calendar
Month calendar and list view of everything scheduled — edit or delete before it goes out.
🔁 Content recycling
Toggle "repost every N days" and evergreen content re-queues itself after each successful publish.
🚨 Statuses that tell the truth
Scheduled → publishing → published / failed with the actual API error, plus a Retry button that only re-hits the channels that failed.
🔒 100% yours
SQLite on your disk, in-process 1-second scheduler (no Redis, no cron daemon), crash-safe recovery, zero telemetry.
$129 once — that's the whole pricing page
Buffer charges $6/channel/mo — roughly $360 a year, every year. PostDock is a single payment, and it keeps working whether or not we ever sell another copy.

Honest answers
Is it really free on GitHub?
Yes — the full source is MIT at github.com/bensblueprints/social-scheduler-mvp. $129 buys the signed installer, 1-click setup and updates — pure convenience, zero lock-in.
Do I need my own API keys?
Yes — that's the point. Bring-your-own-keys means every credential stays on your box and nobody can throttle or re-price your channels. In-app guides walk you through each network: Mastodon and webhooks in 2 minutes, Meta in about 20.
Does Instagram work from a desktop?
Instagram publishing needs a public URL because Meta's API downloads your images from it — so IG requires the $5 VPS mode with PUBLIC_BASE_URL set. Every other channel works fine from a desktop behind NAT.
