INX Social vs PostingCat in 2026: AI campaign studio vs affordable agency scheduling
INX Social brings AI campaigns, images, carousels, and multi-model video into a nine-network publishing workspace. PostingCat prioritises client workspaces, external approvals, calendar controls, analytics, automations, and a public API at a notably lower annual-billing entry price.
INX Social
PostingCat- PostingCat Professional costs $12.49 monthly billed annually for 10 channels, five workspaces, two seats, analytics, and 300 API posts monthly.
- INX Social Creator costs £18.99 monthly for five accounts, unlimited scheduling, Full Analytics, and 300 shared AI credits.
- PostingCat Agency includes secure external post-review links, 25 workspaces, five seats, 50 channels, and 2,000 public API posts monthly.
- INX AI Campaign generates 10, 15, 20, or 30 text, image, or mixed posts and can preserve that sequence in Bulk Scheduler.
- PostingCat Free includes two channels, one workspace, analytics, 200 drafts, and an immediately limited but refillable queue of 10 scheduled posts per channel.
- INX lists AI campaigns, images, carousels, UGC ads, stock video, and more than 60 generation-ready video models on a shared-credit balance.
- PostingCat publishes analytics support for Facebook, LinkedIn Pages, YouTube, Pinterest, and Threads, rather than every platform it can schedule.
PostingCat is the better value for a small agency that already has creative assets and needs separate client workspaces, a calendar, approval links, and a documented API. Professional costs $12.49 per month billed annually for 10 channels, five workspaces, two seats, analytics, and a 300-post monthly API allowance. Agency costs $50 monthly billed annually and adds 25 workspaces, five seats, 50 channels, external reviews, and 2,000 API posts. INX Social is the better option when the team still needs to make the work it will schedule. Creator is £18.99 monthly for five accounts, unlimited scheduling, Full Analytics, and 300 shared AI credits, while AI Campaign can assemble 10 to 30 posts before passing the sequence to Bulk Scheduler. The decision is straightforward: buy PostingCat for client operations and controlled automation, buy INX for asset production. Neither profile makes a case for calling the other a complete substitute.
The tools at a glance
INX Social
AI campaign production and nine-network scheduling for teams that need assets before a calendar
INX Social combines a scheduler with the creative work a basic calendar normally assumes has already happened. It supports Facebook, Instagram, LinkedIn, TikTok, YouTube, Pinterest, Threads, Bluesky, and X. Users can work from a single post, uploaded media, or a saved AI Campaign, then use Bulk Scheduler and Calendar to organise drafts, scheduled work, completed posts, and failures. Formats and analytics remain dependent on each network’s available permissions.
Its AI Content Studio is why it is a genuine alternative to a cheaper scheduling tool. AI Campaign makes 10 to 30 text, image, or mixed posts with optional website grounding. Image Post, Carousel Post, UGC Ad Studio, Stock Video Creator, captions, rewrites, hashtags, calls to action, and alt text sit in the same environment. The Video Studio offers text-to-video, image-to-video, and supported reference workflows across more than 60 generation-ready models. For a small brand without a deep asset library, this can remove a production bottleneck that PostingCat does not try to solve.
INX charges by connected-account capacity and a shared credit balance. Creator includes five accounts and 300 credits at £18.99 monthly, Pro 12 and 900 at £34.99, and Agency 50 and 4,000 at £99.99. All paid plans list unlimited scheduling, Full Analytics, and the creation suite. In exchange, the reviewed profile does not document PostingCat’s workspaces, role structure, external approval links, public API limits, or automations. It is a better creative surface, not a better documented client-operations platform.

PostingCat
Multi-client scheduling, workspaces, external approvals, automations, analytics, and a public API
PostingCat is an agency-aware scheduling product with a practical free entry point. Its calendar provides daily, weekly, and monthly views, drag-and-drop rescheduling, previews, share links, timezone management, and channel-specific configuration. It lists scheduling for Instagram, TikTok, LinkedIn profiles and Pages, Facebook Pages, X, YouTube, Pinterest, Dribbble, Threads, and Reddit. One post can be adapted for several networks before it enters the queue, while a workspace separates each client’s channels, calendar, drafts, media, and approvals.
The operational surface is its advantage over INX. Professional has 10 channels, five workspaces, two seats, analytics, an editor, and API access at $12.49 monthly billed annually. Agency adds 50 channels, 25 workspaces, five seats, and external reviews at $50 monthly billed annually. An external reviewer can use a secure link without a PostingCat account, comment, request changes, and approve a post. The published approval condition prevents it from publishing until that review is complete. PostingCat also documents recycling, engagement-triggered reposting, follow-up comments, account reposting, and publish-email automations.
The limits are specific enough to matter. X is unavailable on Free, capped at 250 posts monthly on Professional and 2,500 on Agency. Professional lists 300 API posts monthly and 350 requests per hour, while Agency lists 2,000 and 2,100. Its published analytics page names Facebook, LinkedIn Pages, YouTube, Pinterest, and Threads, so publishing support should not be mistaken for equal reporting on every connected network. PostingCat has AI drafting and image allowances, but it does not claim INX’s campaign generator or multi-model video studio.

Which should you choose?
INX SocialINX SocialPostingCatPostingCat is the more deliberate purchase for client-service work because it publishes concrete workspace, seat, approval, and API limits. INX Social is the more useful purchase for a team that cannot fill those client calendars without help producing assets. The apparently lower PostingCat price reflects a different responsibility: it helps organise and govern existing content, while INX uses a shared credit meter to generate it.
Bottom line
Choose INX Social Creator when visual production is the constraint and five connected accounts cover the intended distribution. Its trial is the right place to measure whether 300 shared credits can support the planned campaign and video cadence. Choose PostingCat Professional for low-cost multi-brand scheduling and a controlled public API, then move to Agency only when external reviews, larger workspace capacity, and higher API limits are genuine requirements. Do not assume PostingCat’s analytics cover every platform it schedules.
Frequently asked questions
Is INX Social or PostingCat better for an agency that needs client approval before posts go live?
PostingCat Agency is the better choice for an agency that needs client approval before posts go live because it includes secure external review links that let a stakeholder comment, request changes, and approve without an account. INX Social’s reviewed profile does not publish a comparable approval workflow.
Which tool has a public API for a small agency social publishing workflow?
PostingCat includes public API access on Professional and Agency, with 300 or 2,000 API posts per month and published hourly request limits. INX Social’s reviewed profile does not publish a customer-facing API, so PostingCat is the safer choice when documented automation is mandatory.
Can PostingCat create the same AI video campaigns as INX Social?
PostingCat cannot be treated as an equivalent AI video campaign tool because its documented AI features are drafting, post generation, and image generation allowances. INX Social documents AI Campaign, stock-video creation, and a multi-model Video Studio for text-to-video and image-to-video workflows.
What does PostingCat Free include for a creator testing a social calendar?
PostingCat Free includes two channels, one workspace, analytics, 200 drafts, and unlimited scheduled posts subject to a 10-post-at-once queue per channel that refills. It excludes X publishing, external reviews, and public API access.
How should an agency compare INX credits with PostingCat annual pricing?
An agency should compare INX credits against the volume of campaign and video generation it actually needs, because the credit pool is shared across AI tools. PostingCat’s annual-billing price buys client-workspace and publishing operations rather than an equivalent creative-output allowance.
