API-first design
The API is the product, not a feature gated behind a dashboard plan.
The Developer-First Publer Alternative
Publer is a scheduling dashboard that added an API on its Business plan. Postproxy is an API built for developers from day one — with free access, 7 SDKs, and multi-tenant isolation.

OVERVIEW
TL;DR
A quick take in two columns, then the detailed comparison below.
Publer
Publer is a scheduling dashboard. The API launched in 2025 as an add-on, available only on the Business plan at €8.72/account/month. For 10 accounts with API access: ~$95/mo. Free and Professional plans have no API at all. No SDKs, no multi-tenant model, no n8n, no MCP server, no documented failure handling.
Postproxy
Postproxy is an API. Every plan includes API access, starting with a permanent free tier. 7 typed SDKs, scoped API keys for per-client isolation, queue system with timeslots and priority, per-platform state machine. Billed per connected profile: for 10 accounts $37/mo vs ~$95/mo, at 50 accounts $132/mo vs ~$475/mo, at 100 accounts $207/mo vs ~$950/mo. Publer is for teams who schedule through a browser — Postproxy is for code that publishes programmatically.
