PostingCat vs Sendible in 2026: low-cost workspaces and API limits versus established agency delivery

PostingCat is a scheduling platform that gives a small team more operating structure than its price suggests. Workspaces separate a client or brand’s channels, calendar, drafts, media, and approvals; roles distinguish owners, admins, and members. Its calendar supports daily, weekly, and monthly views, drag-and-drop rescheduling, sharing links, post previews, time zone management, and network-specific configuration. Publishing support covers Instagram, TikTok, LinkedIn profiles and pages, Facebook Pages, X, YouTube, Pinterest, Dribbble, Threads, and Reddit.

The Free plan covers two channels, one workspace, one seat, 200 drafts, analytics, and 10 scheduled posts at once per channel, subject to the published queue and fair-use rules. Professional costs $12.49 per month billed annually for 10 channels, five workspaces, two seats, unlimited scheduled posts, analytics, a picture editor, and public API access. The API allowance is 300 posts monthly and 350 requests hourly. Agency costs $50 monthly on annual billing for 50 channels, 25 workspaces, five seats, and 2,000 API posts monthly with 2,100 hourly requests.

Agency is also the first tier with external post reviews: a client can receive a secure link, comment, request changes, and approve without a PostingCat account. That is a real advantage for a lean agency, although the published analytics coverage names Facebook, LinkedIn Pages, YouTube, Pinterest, and Threads rather than every publishing destination. X is unavailable on Free, capped at 250 posts per month on Professional, and capped at 2,500 on Agency. Automated white-label PDF reports are described as in progress, so buyers who promise branded client reporting today should not treat them as included.

Sendible is shaped around an agency that has to keep client accounts separate while letting many people participate. Each workspace is a home for a client, brand, or location with six social profiles, its own calendar, queues, messages, reports, and settings. Every published plan includes unlimited users, so clients, freelancers, and approvers do not create a per-seat bill. Client Connect lets a client attach social profiles without sharing credentials, which is a meaningful operational detail for a managed service.

Core costs $35 per month billed monthly for one workspace and six profiles. Plus costs $99 for three workspaces and 18 profiles, adding assignments and approval workflows. Premium costs $199 for seven workspaces and 42 profiles, adding content libraries, custom branded reports, campaigns, dedicated onboarding, and an account manager. Elite rises to $299 for 15 workspaces and 90 profiles with advanced user permissions; Enterprise is $750 for 50 workspaces and 300 profiles. Each workspace has a daily send cap, from 100 on Core to 500 on Elite and Enterprise, despite unlimited advance scheduling.

Sendible publishes to Instagram, Facebook, TikTok, X, LinkedIn, Google Business Profile, YouTube, WordPress, Threads, and Bluesky. Smart Queues support evergreen schedules, and bulk CSV scheduling, platform-specific posts, AI Assist, UTM parameters, Canva, Google Drive, Dropbox, and Zapier support routine work. The compromise is that white labeling is a paid add-on only on Elite and Enterprise, and real-time reply coverage is narrower than the publishing list, specifically naming Facebook, Instagram, and LinkedIn. Sendible is a more expensive decision than PostingCat, but it is the more complete client delivery platform once Premium is justified.
