OneTimeSchedule to X, Facebook, Instagram, LinkedIn and Mastodon from your own box — pay once.
Buffer charges $6 per channel per month, forever — five channels is $360 a year, every year. PostDock is the same core workflow — compose, preview, schedule, queue, recycle — running on your machine or your $5 VPS, with your own API keys. Nobody can raise the price on you, throttle your channels, or hold your posting history hostage.
PostDock in 60 seconds
Everything in the box
Self-hosted social scheduling — composer, queue, content recycling & webhooks. Your API keys, your data.
5 pluggable channels
X/Twitter, Facebook Page + Instagram Business, LinkedIn, Mastodon — all with your own API keys, every credential on your box.
Webhook escape hatch
POSTs the content JSON to Zapier, Make, n8n or your own endpoint with optional HMAC-SHA256 signing — your route to every other network.
Composer with live previews
Text + up to 4 images, per-network character counters (280/500/2200/3000) and preview cards per channel.
Timezone-aware scheduling
Pick any IANA timezone; DST handled correctly. Post now or schedule.
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.
PostDock vs Buffer
Buffer charges $6/channel/mo. Here's what actually differs.
| PostDock | Buffer | |
|---|---|---|
| Price | $129 once | $6/channel/month, forever |
| 5 channels, 3 years | $129 | $1,080 |
| Channel limit | Unlimited | Pay per channel |
| Scheduled posts | Unlimited | Capped on cheap tiers |
| Your API keys & data | SQLite on your disk | Their cloud |
| Content recycling | Built in | That's ReQueue/SmarterQueue — another $25/mo |
| Webhook / Zapier escape hatch | Built in | Paid add-ons |
| Source code | MIT, yours forever | Closed |
A five-channel Buffer setup pays for PostDock in about 4 months — even a single channel breaks even in under two years.
Pick how you pay
Subscriptions if you want them — but the whole point is the lifetime tier.
Up and running in three steps
Buy once on Whop
One-time $129 for the packaged Windows installer — no terminal, no build step, updates included.
Connect your channels
Every driver has a step-by-step guide inside the app. Mastodon and webhooks take 2 minutes; X about 10; LinkedIn 15; Facebook + Instagram around 20.
Compose, schedule, recycle
Per-network previews and counters, a timezone-aware queue, and evergreen recycling that keeps your best content circulating.
Fair questions
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.
What about TikTok, Pinterest or Threads?
No native drivers yet — honestly. The webhook driver plus Zapier/Make/n8n covers them today, and drivers are pluggable (one file in server/channels/) if you build from source.
Is this a subscription in disguise?
No. $129 once. No renewal, no license server phoning home, no per-channel meter. The app keeps working forever, even offline.
