Who is Postbase for?
Write a post once, tailor it for each network, and plan the whole week in one sitting.
A workspace per client, each with its own channels and people. Invite teammates as admins or members.
Give Claude, Cursor or your own code a key, and let it schedule over MCP or the REST API.
Available channels
Customize per channel
New on the shelf: Kochere, Ethiopia ☕️ Apricot, black tea and a little bergamot.
Everything you need to post, in one place
From the first draft to the numbers afterwards, without leaving Postbase.
See the whole month at a glance
Every post you've drafted, scheduled and published, in a month, week or day view. Click an open slot to write a post for that time.
Here's a post for all three, with a shorter cut for X. It's set for Wednesday at 12:00.
Tell it what to post. It does the rest.
Describe a post in one sentence. The agent checks your channels, writes it for each network and lines it up for the time you asked. Nothing goes out until you say so.
One post, tailored for every network
Write it once, then adjust the wording for each network. Every version keeps to that network's character limit.
Available channels
Customize per channel
New on the shelf: Kochere, Ethiopia ☕️ Washed process, light roast. In the cup it's apricot, black tea and a little bergamot. Roasted Monday, shipped Tuesday. 40 bags this week, and they go fast.

Frequently asked questions
Is Postbase open source?
Yes. The code is on GitHub, and you can run it yourself for free with your own platform API keys. The hosted cloud is the paid, managed option.
Is there a free trial?
Yes. Every plan starts with 7 days free. A card is required, and you can cancel any time before the trial ends.
Can AI agents post through Postbase?
Yes. Add Postbase to Claude as a custom connector, or run @postbasehq/mcp in Cursor or any MCP client. Agents can list your channels, create and schedule posts or threads, check the queue and cancel posts.
Which networks does Postbase support?
X, LinkedIn, TikTok, YouTube, Bluesky and Mastodon today (TikTok posts are private for now, until TikTok approves public posting). Instagram and Facebook are coming soon, once Meta approves our app, and Threads is on the way too.
Is there a public API?
Yes. The REST API uses bearer keys you create on the AI & API page. You can list channels, list and create posts, and cancel scheduled posts. Keys are stored as hashes and can be revoked any time.
Can I edit a post for just one network?
Yes. Each network gets its own version of the post, so you can change the LinkedIn wording or turn the X version into a thread without touching the others.
What happens if a post fails to publish?
Postbase retries temporary failures automatically. If a post needs you, for example because an account has to be reconnected, you'll see it in your notifications.
Can I manage several brands or clients?
Yes. Each workspace has its own channels and team, and you can switch between them from the sidebar.
