Our shortlist
| Tool | Best for | Published starting point | Main trade-off |
|---|---|---|---|
| Sendible | Small agencies that need client workspaces, approvals and reporting | $35/mo Core | Advanced agency/white-label needs push you into higher tiers |
| Postrivio | Agencies specifically buying AI campaign execution | $40/mo standard monthly | Newer product; real-world maturity still needs validation |
| Buffer | Simple publishing, analytics and team workflows | $5/channel/mo Essentials on annual billing | Less centered on full agency client operations |
1. Sendible — best default for a small agency
Sendible currently includes unlimited users across its plans and scales by workspaces and social profiles. Its Plus tier adds assignment and approvals, while Premium adds custom branded reports. This maps cleanly to common agency workflows.
Choose it if: client separation, approvals and reporting matter more than experimental AI automation.
2. Postrivio — best for automation-first agencies
Postrivio's main reason to exist in this shortlist is not price. It is its attempt to let Otto execute campaigns and automate more of the operating work. The Agency plan also adds client workspaces, approvals, reports and billing features.
Choose it if: you are explicitly trying to reduce hands-on content and campaign work with AI, and you are willing to test a newer platform carefully.
3. Buffer — best when you want less software
Buffer's current paid plans are priced by channel. Essentials starts at $5 per channel per month on annual billing, while Team starts at $10 per channel per month and adds unlimited team members, access levels and content approval workflows.
Choose it if: you mainly need a clean publishing and collaboration layer and do not need a deep multi-client agency operating system.

What we have not proven yet
Published pricing and feature lists do not prove uptime, support quality or day-to-day workflow quality. We are deliberately separating verified vendor facts from judgments and will update these pages as hands-on testing expands.
