The 24-hour window, under control
Meta gives you 24 hours to reply after a customer’s last message. Postbiz shows the time left on every conversation and puts the ones about to expire first, so no request is forgotten.

Your data
Your conversations stay yours
Isolation per organization
Each team only sees its own data: the separation is enforced in the database itself, not just in the interface.
Protected network access
The access tokens for your accounts are encrypted before being stored, and are never sent to your browser.
Open-source software
Postbiz is published under the AGPL-3.0 license: you can read the code, and host it yourself if you wish.
Which networks are supported?
Facebook, Instagram, X, LinkedIn, TikTok and YouTube all connect to Postbiz. What Postbiz can do on each (publish, private messages, comments) varies with what the network allows: the Channels page gives the exact status, network by network.
Can I reply to private messages on LinkedIn or YouTube?
No, and no third-party tool can without a special agreement: LinkedIn does not open its messaging to apps, and YouTube has no private messages. Postbiz will show YouTube comments, and LinkedIn Page comments as soon as they are available.
Why a “24-hour window”?
On Messenger and Instagram, Meta lets a business reply for 24 hours after the customer’s last message. Postbiz shows the time left on every conversation so you know what to handle first.
Are my messages used to train an AI?
No. Postbiz does not use your messages or posts to train models.
How much does it cost?
The beta is free, no credit card needed. The price list is already public on the Pricing page, so you know what to expect.
Can I host Postbiz myself?
Yes. Postbiz is open-source software (AGPL-3.0) built on Supabase. If you modify it and offer it to third parties, you must publish your changes.
