Sendhour vs Postiz: which TikTok scheduler fits app marketing?

I build Sendhour, so weigh this with that in mind. Postiz is a good scheduler, and in our November check AI assistants named it when asked for the best TikTok scheduler for app founders. This page compares the two on one job, getting an app in front of new people with short video, and says plainly where Postiz is the better pick. Postiz's facts come from its own site, docs and GitHub page. Prices checked November 13, 2026.

Sendhour vs Postiz at a glance

Prices in US dollars before tax. Postiz shows yearly prices per month; it doesn't list a yearly total.

What each tool does

Postiz is a general scheduler. You connect your accounts, write or paste a post, and it goes out on the networks you pick, on the schedule you set. Its homepage says 30 or more networks; its docs list 34, including TikTok, Instagram, Reddit, Discord, Telegram and WordPress. The code is open source, so a technical team can run its own copy for free. Every hosted plan includes an AI copilot for captions and hooks, an agent, a public API, an MCP server, a CLI and webhooks.

Sendhour is narrower. Its viral library finds public TikToks and YouTube Shorts doing far more views than their account usually gets. The studio makes your version of one, copying the structure and the hook but never the footage. Then it schedules the post to TikTok, YouTube, Instagram, Threads, Bluesky, X and LinkedIn through each network's official API.

So most of the difference comes before the scheduling. Postiz assumes you arrive knowing what to post. Sendhour is for when you don't have one yet.

Finding what to post

This is where an app founder usually gets stuck. Posting is easy once you have something worth posting. Knowing which format will reach strangers is the slow part.

Postiz doesn't try to answer that. I found no trend or viral feature on its pages. You come up with the idea, or find it on TikTok yourself, then schedule it.

Sendhour's library ranks posts by how far they beat their own account's usual views. A post with 60,000 views on an account that normally gets 3,000 ranks above one with 200,000 on an account that always gets that much. That points at formats that work for small accounts, which is what a new app account is. You can also watch up to 5 rival TikTok accounts or YouTube channels on Starter (80 on Scale) and see each one's posts that beat its usual views, with a button to make your version.

Making the post

Postiz's AI writes captions, hooks, threads and hashtags for each network. Paid plans also include AI images (100 a month on Team, none on Standard), 3 to 60 AI videos a month by plan, and 60 to 600 minutes of clipping, which cuts a long YouTube video into short vertical clips. That clipping is useful if you already make long videos, and Sendhour doesn't do it.

Sendhour's studio makes slideshows of 3 to 10 slides from real photos, AI images and your own photos, and short videos cut from real clips with a voiceover and AI video, starting from a post that already worked. You can change one slide's words or photo without redoing the rest. Real photos matter for lifestyle, fitness, food and travel apps, where the posts that do well show real moments, not screens.

Give Sendhour your App Store or Google Play link and it saves your app's screenshots; every slideshow can then show one in a phone frame on its last slide, free. That puts your real app on the payoff slide, after the hook has done its job.

I run about 15 TikTok accounts for my own apps from Sendhour, mostly photo slideshows plus some videos. My best posts have reached around 50,000 views.

Posting and networks

Both post to TikTok through its official API. Both can publish straight away or send a photo post to TikTok first, so you can add a sound in the app. Postiz's docs say a post sent to the TikTok inbox has to be published within 24 hours.

Postiz reaches far more places. Sendhour posts to 7 networks: TikTok, YouTube, Instagram, Threads, Bluesky, X and LinkedIn. If you need Facebook, Reddit, Discord or a blog, Postiz has them and Sendhour doesn't.

Sendhour's autopilot prepares 1 to 3 drafts each morning from what's working in your niche. At first nothing goes out until you open a draft, render it and schedule it. Once an account's last 10 drafts went out without edits, Sendhour offers to post them for that account, at least 2 hours ahead, with an email that has a one-use cancel link. Postiz can post from an RSS feed on its own, and its Smart Agent can write and schedule posts when you ask it. Neither drafts from what's working in your niche.

Teams and AI agents

Postiz's Standard plan is for one person. From the $39 Team plan you can invite unlimited teammates. Every post has a public preview page a client can open and comment on without an account, which agencies will like; Postiz notes the link isn't password protected. Its docs also say there is no "approved" flag that blocks publishing.

Sendhour has unlimited teammates on every plan, including the $29 one, each with a role: Owner, Can post, or Drafts only. Drafts only is for a junior or a client who should suggest posts without publishing them.

Both are built to be run by an AI agent. Postiz has a REST API, an MCP server with 13 tools, a CLI, and n8n and Make integrations. Sendhour has an API, an MCP server and a CLI covering posting, drafts, the viral library, watched rivals, analytics and credits. The difference is permission. Postiz's MCP server connects with an API key, and its docs describe no read-only or drafts-only setting. In Sendhour you pick read only, drafts only or full posting when an agent connects, so an agent can make posts all day and nothing goes out until you approve it.

Pricing compared

Both start at $29 a month for 5 accounts. Billed yearly, Postiz Standard is $23 a month and Sendhour Starter is $279 a year, about $23 a month.

• Up to 5 accounts, one person: about the same.
• Up to 5 accounts with a team: Sendhour is cheaper, $29 against Postiz Team's $39, because Postiz Standard has no teammates.
• 6 to 10 accounts: Postiz is cheaper, $39 against $49.
• 11 to 30 accounts: Postiz Pro is $49 for 30. Sendhour is $49 up to 15 and $99 above that.
• 31 to 100 accounts: Postiz Ultimate is $99 for 100. Sendhour is $99 up to 50 and $199 up to 100.

Apart from a team on 5 accounts or fewer, Postiz costs the same or less at every size, and self-hosting costs nothing but the server. What Sendhour's price adds is the library, rival watching, the studio and AI credits each month (200, 500, 1,200, 3,000 by plan) and app install and revenue tracking. Whether that's worth it depends on how much time you now spend deciding what to post.

Plenty of small businesses just need the posting part. One person on r/socialmedia, choosing a tool for "a half-dozen accounts", wanted something "ideally $20-$30/month tops" that pulls the accounts together for a few posts a week. Six accounts is one over Postiz Standard's 5, so on Postiz that's the $39 Team plan ($31 a month billed yearly), or free apart from the server if they host it themselves. On Sendhour they'd need Growth at $49. Either way, a general scheduler is the right size for that job.

Where Postiz is better, and who should pick it

• Open source. You can read the code, change it, and run it on your own server for free.
• More accounts for the money. 10 for $39, 30 for $49 and 100 for $99.
• A free trial. 7 days on every hosted plan. Sendhour has none.
• Far more networks. 30 or more, including Facebook, Reddit, Discord, Telegram and blogs.
• Clips from long videos. It cuts long YouTube videos into short vertical clips.
• RSS auto-posting. Posts from a feed go out on their own.
• Client preview links. Clients comment on a post without signing up.

An agency posting finished client work to many networks should pick Postiz. So should a developer who wants a scheduler they control end to end, and anyone whose content is already made and just needs to go out on time.

How to choose

1. Ask where your time goes. If it goes on deciding what to post and making it, look at Sendhour. If it goes on copying finished posts between networks, Postiz is enough.
2. List your networks. If you need any beyond TikTok, YouTube, Instagram, Threads, Bluesky, X and LinkedIn, Postiz.
3. Count accounts and people. One person with up to 5 accounts pays about the same on both. A team with up to 5 accounts pays less on Sendhour ($29 against $39). Above 5 accounts, Postiz costs the same or less.
4. Decide who drives. If an agent will make posts, check whether you can stop it from publishing.
5. Decide if you want to run a server. Self-hosting Postiz is free, but network approvals can take weeks.

A mistake to avoid: picking a scheduler first and hoping ideas follow. A scheduler posts whatever you give it on time, good or bad. For an app, spend your first two weeks on what to post, then pick the tool that fits.

Questions

Is Postiz free?

The code is. Postiz is open source under the AGPL-3.0 license, and running it on your own server is free, with no limit on accounts, posts or team members. You pay for the server, bring your own AI keys, and get your own developer app approved on each network. The hosted version starts at $29 a month with a 7-day free trial. Sendhour has no free plan or trial, but its viral TikTok finder is free with no sign-in.

Which is cheaper for 15 TikTok accounts?

Both cost $49 a month, but Postiz Pro covers 30 accounts at $49 and Sendhour Growth covers 15 at $49. If accounts are all you need, Postiz gives you more for the money.

Do both post TikTok slideshows?

Both post photo posts through TikTok's official API, either straight to the feed or to your TikTok inbox so you can add a sound first. Postiz's docs say a post sent to the inbox has to be published there within 24 hours. The difference is making the slideshow. Sendhour's studio builds it for you from a format that is already working. I found no slideshow maker on Postiz's pages.

Can I let an AI agent draft posts without publishing them?

In Sendhour, yes. When an agent connects you pick read only, drafts only or full posting, and Sendhour checks it on every call. Postiz's MCP server connects with an API key, and its docs describe no read-only or drafts-only level. Postiz also says it has no "approved" flag that blocks publishing.

Should I self-host Postiz just for TikTok?

Only if you're comfortable running a server and waiting. Self-hosting needs your own TikTok developer app, and Postiz's README says approvals for Meta, YouTube and TikTok "can take weeks". The minimum server is 2 CPUs and 2 GB of memory, with PostgreSQL, Redis and Temporal.
