Does Postproxy have an API?

Yes; the whole product is built around one. Every plan ships scoped multi-tenant API keys, state machines for error handling, and priority queues with jitter.

How much does Postproxy cost for 50 channels?

$99/month flat for 50 profile groups. It's one of the few tools in our test set that gets cheaper on paper the more tenants you add.

What are 'scoped multi-tenant keys'?

Each customer gets a key that can only touch their own profiles. It rules out the accidental cross-tenant post that keeps SaaS founders awake.

Does Postproxy integrate with n8n?

Yes, via native n8n nodes. That saved us building a custom HTTP wrapper when we wired it into a scheduled workflow.

Who is Postproxy for?

SaaS teams that need clean tenant isolation, retries, and queue behavior they can explain to customers.

Postproxy makes the most sense when your customers are posting through your product, not when a marketer wants a calendar. Scoped keys, per-tenant isolation, and state machines are the point here. At $99 flat for 50 profile groups, it is one of the few tools in this list that gets cheaper than it looks once you model a real SaaS setup.

Multi-tenant posting API with scoped keys, queue control, and the SaaS features dashboards rarely ship.
