ViewportScheduler & analytics for one operator
Most analytics tell you what happened.This one tells you what works.
Viewport posts your videos to Instagram, YouTube and TikTok, then works out from your own posts which signals predict reach — on your account, not the average one.
Self-hosted · your accounts, your database · Instagram, YouTube, TikTok
Live from the account it was built for. Three signals are shown because three hold up. Two more were tested and dropped — a signal that can't beat a coin flip doesn't get a tile.
The line is found, not typed
Your account is not the average account.
Every guide has a number for you. Hook them in three seconds. Aim for four percent. None of it was measured on your audience.
Viewport sorts your posts by whether they out-reached your own median, then finds the cut that best separates the two piles. That cut is your line, and it moves as you post. The accuracy it shows is scored on posts it hasn't seen — so it can't flatter itself.
The queue
One video, one card.
A clip posted to three platforms is one card, not three. Open it and each platform gets its own tab — the same video can clear every signal on TikTok and miss them all on Instagram, and that gap is the interesting part.
Before it goes
You see exactly what each platform will get.
The last screen puts the video beside the caption Instagram receives, the title and description YouTube receives, and the caption TikTok receives. Side by side, because the differences are what people get wrong.
For TikTok you choose who can see it. Nobody chooses for you.
Written, if you want it
A short read of the last thirty days.
Grounded in the posts themselves, with the numbers next to each claim so you can check it. Optional — it needs a free key, and everything else works without it.
The TikTok problem
Usually you pick two: your own data, or TikTok that just works.
TikTok makes every app that posts publicly get registered and audited by TikTok first. Buffer and Later did it once, for everyone — which is why their TikTok works, and why your videos and your numbers live on their servers on a subscription that never ends.
Self-hosted tools give the data back and hand you the audit: register as a developer, own a domain, record a demo of your own software, wait a week. Most people stop there.

Your data stays on your own accounts, and the TikTok audit was done once — by us, for everyone.
Plainly: TikTok posting runs through a small service I operate. If it stops, TikTok posts wait in the queue and go out when it's back — Instagram and YouTube never touch it. Fifteen TikTok posts a day per licence, below TikTok's own limit. And if you'd rather not depend on me, put your own TikTok app in and the service steps aside.
Before you buy
Three things that might make this the wrong tool.
One password, one set of accounts, no roles, no approvals. If anyone else needs to see the queue before a post goes out, this will fight you.
Four free accounts, about thirty minutes, a guide, and a setup check that tells you which service is wrong.
Instagram's API won't post to a personal one. It is the single most common thing that stops a setup.

Stop guessing which post worked.
