Best Social Media Schedulers for Agencies (2026)
Last fact-check: July 2026
Agencies live and die on tooling cost. For the same job — 50 client channels, approvals, white-label reports — prices in 2026 range from $99/mo (Postproxy flat) to over $350/mo (Sprout Social, Hootsuite). We ranked 7 tools that actually serve agency workflows.
The pattern is clear: per-seat and per-user tools like Sprout, Hootsuite, and Agorapulse get expensive quickly, while volume-based Postproxy and per-account tools such as Zernio, Publer, and Metricool keep costs predictable as you onboard clients.
