TL;DR
SocialAPI.ai shipped engagement automation first - their 75-tool MCP surface for DMs, comments, and replies is real. Publish Now is the unified social API focused on scheduling-first posting today, with engagement automation explicitly on the roadmap. Pick by what you need shipping now.

The reasons people search
7-platform ceiling becomes a bottleneck as the long tail (Bluesky, Pinterest, Mastodon, Reddit) starts mattering to your customers.
Scheduling is a side feature, not the primary surface; queues, batch jobs, retries, and calendar windows live in your glue code rather than the API.
No public uptime SLA, no centerpiece status page, so your buyers cannot verify reliability the way they can with a published number.
Multi-tenant SaaS posture is not first-class; the product is built for AI agents operating one brand's inbox, not for an API sitting under your own product serving thousands of end-user accounts.
Pricing scales with brand count, which gets awkward fast when the unit you actually bill on is end-user accounts, not brands.
Engagement automation (comments, DMs, replies): Shipped, 75+ MCP tools
Scheduling depth: Side feature; basic schedule-a-post
Platforms supported: 7 (Instagram, Facebook, Threads, TikTok, YouTube, X, LinkedIn)
MCP tools count: 75+ tools across publishing and interactions
MCP marketplace distribution: Smithery, Composio, MCP.so, PulseMCP
Engagement automation (comments, DMs, replies): On the roadmap as Pillar 2
Scheduling depth: First-class workflow with queues, batch jobs, retries, calendar primitives
Platforms supported: 3 live at GA (X, Instagram, YouTube), more on the roadmap
MCP tools count: Publishing and scheduling MCP at GA; engagement tools land with Pillar 2
MCP marketplace distribution: Targeting major marketplaces at GA
SocialAPI.ai got engagement automation to market first. The 75+ MCP tools for comments, DMs, and review replies are real, listed on Smithery, Composio, MCP.so, and PulseMCP, and unlimited interactions are baked into every paid plan. If inbox automation is the job your product has to do today, that is a real wedge and we are not pretending otherwise.

The shape of the product, not just the pitch.
SocialAPI.ai is interaction-first; scheduling is something the API supports, not the workflow it is built around. Publish Now treats scheduling as the spine. Queues, batch jobs, retries, calendar windows, and platform-aware rate limiting live inside the API instead of your glue code.
SocialAPI.ai does not publish an uptime SLA today. Publish Now commits to a 99.9% uptime target at GA, a public status page, and real incident history. Your buyers get a number they can put in a procurement doc instead of a vibe.
SocialAPI.ai's center of gravity is an AI agent driving one brand's inbox. Publish Now is built for the developer putting a social API inside their own product and serving thousands of end-user accounts behind it. Multi-tenant is the default posture, not an upgrade conversation.
Post to every supported network with the same payload. Per-platform variants are overrides on the same body, not separate endpoints, so your product code stays small as the platform list grows.
$5/mo plus credits, flat. SocialAPI.ai's plans cap brand count, so the bill scales with how many brands you connect. Publish Now stays the same whether you are running 1 brand or 1,000 end-user tenants behind your product.
Honest answer: SocialAPI.ai ships comments, DMs, and replies today and we do not. Engagement automation is our Pillar 2, explicitly on the roadmap. When it lands, it lands on the same JSON shape, the same API key, and the same MCP surface that powers posting and scheduling.
Run the same scale-up against both and you stop second-guessing the bill.
| Scale | SocialAPI.ai | Publish Now | Delta |
|---|---|---|---|
| Solo dev (1 brand, low volume) | Free tier: 2 brands, 10 posts/mo, 50 interactions/mo | $5/mo + credits | Free tier covers smoke tests; paid kicks in for real volume. |
| Agency (5 brands, scheduling-heavy) | Paid tier, unlimited posts and interactions, brand-scoped | $5/mo + credits | Same flat price as 100 tenants on Publish Now. |
| SaaS (100 end-user tenants under your product) | Brand-tier pricing scales with brand count | $5/mo + credits | Bill decoupled from tenant count. |
You need DMs, comments, or review replies via an MCP server today and cannot wait for our Pillar 2 engagement surface to land.
You only need the 7 platforms they cover (Instagram, Facebook, Threads, TikTok, YouTube, X, LinkedIn) and the long tail is not on your roadmap.
You are building an AI agent whose primary job is replying to a brand inbox, and unlimited interactions on a flat plan is the pricing wedge that matters most to you.
Publishing and scheduling are the primary workflow, and you want queues, batch jobs, retries, and calendar primitives as first-class API surfaces rather than a side feature.
You are putting a social API under your own product and need multi-tenant posture by default, with pricing that does not scale per brand as you onboard end-user accounts.
You can wait for engagement automation in our Pillar 2, and you want a published 99.9% uptime target plus a real status page your buyers can verify.
Switching from SocialAPI.ai
Migrating between SocialAPI.ai and Publish Now is genuinely two-way and we will tell you which direction makes sense for you. If inbox automation is your primary job today, stay on SocialAPI.ai and run us alongside for scheduling. If publishing and scheduling is the primary job, swap to Publish Now and revisit engagement when our Pillar 2 ships.
Email yo@publishnow.app and the founder will personally tell you whether to switch, run both, or stay put. We are honest about what is shipped vs roadmapped, and we will not push a migration that does not match your shipping deadline.
