Why Postizy

Platforms killed the API.
We use the app itself.

Instagram requires a Facebook Page and 24h window. TikTok requires a manual whitelist. We skip all of it and automate the official apps on your own phones.

Physical device automation

Connect Android via USB/WiFi ADB. Postizy taps through upload flows — caption, hashtags, cover, publish. Same as a human.

scrcpy + UIAutomator + ADB shell

Account warmup engine

Escalating human routines: browse → like → follow → comment → full. Daily goals, streaks, cooldowns, phase progression.

4 phases · conservative defaults

Gesture engine

Randomized scroll curves, tap jitter ±8px, variable typing 80–250ms, idle 1–8s, human hours clustering.

anti-detection heuristics

Calendar scheduling

Month view, drag-to-reschedule, queue timeline, per-platform captions, bulk CSV import, failure auto-retry.

Queue & device pool

Health checks every 60s, auto-reconnect, dispatch to first healthy device, lock during warmup, transactional retry.

Local-first, zero cloud

Everything in encrypted SQLite on your machine. No OAuth servers, no hosting bills, no privacy tradeoff.

How it works

App → ADB → Android → Open app → Compose & post

Connect devices

Plug Android via USB or WiFi ADB. Postizy detects, health-checks, and pools them. Assign devices to accounts.

$ adb devices
emulator-5554 device

Compose & schedule

Drag media, write per-platform captions, pick times on calendar. Queue handles Cron polling and dispatch.

Device posts itself

At schedule time, device opens app, attaches media, types caption with human jitter, taps publish. Status updates live.

Posting to @brand.lab · TikTok

Platforms

One automation path for all four.

No per-platform API quirks. Same ADB + UIAutomator flow, different UI selectors. Version-pinned patchers when apps update.
