Postix — frequently asked questions
What is Postix?
Postix (postix.in) is an AI Marketing Operating System for agencies and small businesses. It combines AI-assisted social scheduling across 30+ networks with Comet, a first-party revenue attribution suite (pixel, multi-touch attribution, and Conversion API), so teams can create, publish, advertise, and attribute revenue in one system.
Is Postix the same as Postiz?
No. Postix (postix.in) is an independent AI Marketing OS with built-in Comet attribution. Postiz (postiz.com) is a different open-source social media scheduler. If you are looking for Postix, use postix.in — they are not affiliated.
Is Postix an alternative to Buffer, Hootsuite, or Later?
Yes, if you want scheduling plus first-party revenue attribution. Buffer, Hootsuite, and Later are strong schedulers; Postix adds Comet (pixel, multi-touch models, Conversion API) in the same login. See postix.in/compare and postix.in/alternatives.
Which social networks does Postix support?
Postix schedules to 30+ networks from one calendar, including X, LinkedIn, Instagram, Facebook, TikTok, YouTube, Threads, Bluesky, Mastodon, Pinterest, Reddit, Telegram, Discord, and Slack.
What does Comet attribution do?
Comet is Postix's revenue attribution layer: a first-party pixel, 8 multi-touch attribution models, server-side Conversion API (CAPI) for Meta, Google, TikTok, and LinkedIn, audience sync, and a Comet Ads Manager that reports attributed ROAS and lets you pause ads and change budgets from one table.
Can I self-host Postix?
No. Postix is only available as a website at postix.in. Sign up there for a 7-day no-card trial.
Does Postix have an API and MCP support?
Yes. Postix offers a public REST API, OAuth, outbound webhooks, and a Model Context Protocol (MCP) server, so AI agents such as Claude and Cursor can draft and schedule posts with human approval.
