Postiz is a strong open-source scheduler. MarquIQ is an autonomous marketing system. The two get compared often because they overlap at the platform-posting layer, but the products are doing different jobs. This comparison is deliberately fair: we will tell you when Postiz is the right call.
The short answer
If scheduling is your bottleneck, pick Postiz. The self-hosted tier is free, the UI is clean, and the AI features are improving quarter over quarter.
If the whole marketing job is your bottleneck, pick MarquIQ. You are paying 79 to 499 USD a month to offload research, drafting, engagement, and measurement, not to schedule Tuesday's LinkedIn post.
Feature by feature

|---|---|---|
| Post scheduling | Yes (flagship) | Yes |
| Content calendar | Yes | Yes |

| Cross-product dedupe | No | Yes (Jaccard over 14-day window) |
| UTM + attribution tracking | No | Yes (inbound endpoint + pixel) |
| Evergreen recycling | No | Yes (90-day age, 45-day cooldown) |
| Outbound webhooks | No | Yes (HMAC-SHA256 signed) |

Pricing
- Postiz: free self-hosted, paid cloud starts around 15 USD a month.
- MarquIQ: 79 USD (Starter), 149 USD (Pro), 499 USD (Agency). All include a 14-day trial.
The price gap reflects the scope gap. Postiz replaces Buffer; MarquIQ replaces a marketing hire. For a founder spending 20 hours a week on marketing, MarquIQ Pro at 149 USD is dramatically cheaper than the time it saves. For a founder who just needs scheduling, MarquIQ is overkill.
When Postiz is the right call
You have marketing under control
You already know what to post, you already engage in communities, and you already measure what works. You just want a calendar and a publish button. Postiz is the right tool.
You want open source
Self-hostable, open-source, and auditable matters to you. MarquIQ is a hosted SaaS. Postiz wins on philosophy here.
You post on platforms MarquIQ does not support
Postiz supports more niche platforms (Pinterest, Threads, others). MarquIQ focuses on the nine that drive SaaS signups. If you need Pinterest scheduling, Postiz wins.
When MarquIQ is the right call
Your bottleneck is drafting, not posting
You have the calendar. You do not have time to write platform-native variants of 15 posts a week. MarquIQ is built for this.
You want engagement automation
You want to scale Reddit, HN, and Indie Hackers engagement without losing your voice or your accounts. Postiz does not do this. See our reply engine guide.
You want closed-loop measurement
Every post scored, attribution tracked back to source, cadence suggestions based on real engagement data. Postiz reports; MarquIQ learns.
The honest summary: these are not the same product. If you can articulate what you need to post on Tuesday, Postiz is enough. If you need a system to help decide what to post, where to engage, and what to stop doing, MarquIQ is the one. Our autonomous marketing guide goes deeper on the loop.
