Why people are leaving Zernio

The bill grows with every account. Zernio charges per connected account: the first 2 are free, then $6 each up to 10, $3 up to 100 and $1 after that. One brand on Instagram, Facebook, LinkedIn and TikTok is 4 accounts, or $12 a month on its own (zernio.com/pricing, October 18, 2026).

Usage adds up on top. Every X post is billed at X's API rates, $0.015 a post and $0.20 with a link. Messages sent from the inbox are free up to 10,000 a month, then $1 per 10,000, and managed ads are metered past 500.

It is built for developers. Zernio's own pricing FAQ says it is built for developers and teams with technical resources. Its docs describe no approval step for posts, so a client sign-off flow is yours to build.

No Mastodon. Zernio publishes to 16 platforms, including Reddit, Discord, Slack and WhatsApp, but not Mastodon. Snapchat is listed but not live yet, because Snap has not approved Zernio's app.

A new name and a wider scope. Zernio used to be Late, and getlate.dev now redirects to zernio.com. Next to social posting it now sells ads management, phone numbers, calls, SMS, RCS and iMessage, all on one usage bill.

What Zernio still does better

• Multi-tenant by design: one profile per customer, white-label and headless connect flows, and webhooks that carry your own customer id. OmniSocials' platform integration for this is coming soon.
• Free for 2 connected accounts, with no card and no trial clock.
• Ads on 8 networks, plus WhatsApp, SMS, calls, Reddit, Discord and Slack through one API.
• No seat fees: teammates are free, and past 100 accounts each one costs $1 a month.
• Higher API limits: 600 requests a minute on paid usage, against 100 per key on OmniSocials.

If you are building a product on top of social APIs, Zernio is the stronger base. OmniSocials is for teams that post for their own brands and clients and want the app, the inbox and approvals ready to use.

Zernio vs OmniSocials pricing

OmniSocials' prices below are billed yearly; Zernio bills monthly by usage, with no yearly plan. Both were checked on October 18, 2026.

OmniSocials: $10 per seat a month billed yearly ($12 monthly), every feature included; X posts with a link use pass-through credits. Zernio: billed monthly by usage, with no yearly plan and no seats: the first 2 connected accounts free, then $6 an account up to 10, $3 up to 100 and $1 after that. A connected account is one profile on one platform, and we count 4 per brand (for example Instagram, Facebook, LinkedIn and TikTok). X API calls, sent messages past 10,000 a month and managed ads past 500 cost extra. From zernio.com/pricing on October 18, 2026.

What you get with OmniSocials

One calendar, filled by you or your AI agent

Plan in a week or month view, keep drafts in the tray and preview each post the way each platform shows it. Connect Claude, ChatGPT or another agent through the MCP server, and the posts it schedules land on the same calendar for you to check. How the MCP server works

One inbox for 7 platforms

DMs, comments and mentions from Instagram, Facebook, LinkedIn, TikTok, YouTube, X and Threads in one list, on every seat. Zernio offers its inbox as an API to build on, with DMs on channels such as WhatsApp, Telegram and Instagram. See the inbox

Repost automations

Post on one platform and let an automation repost it to the others on your schedule, for example your Instagram Reels to TikTok, one a day at 9:00 AM. Automations can also bring in your older posts from 8 platforms. See automations

Approvals for teams and clients

Add approval steps per workspace, so a teammate or client signs off before a post goes live. Reviewers comment, request changes or approve, and roles decide who can post, reply or see analytics. Zernio's docs describe no approval step for posts. See collaboration

For developers

Zernio is an API and MCP server first. Here is how the two compare.

Both have a REST API with Bearer keys, a hosted MCP server, SDKs in 8 languages, a CLI and HMAC-signed webhooks. Zernio goes wider, with ads, messaging and white-label connect flows for your own users. OmniSocials keeps to 12 social platforms and adds the scheduling app, inbox and approvals your team uses every day, for one price per seat.

How to switch from Zernio

1. 1

   Connect your accounts and create a key

   Make a workspace for each brand, connect each account through the platform's own sign-in and create an API key. The API, MCP server and SDKs all work during the 14-day trial.

2. 2

   Repoint your calls

   There is no import from Zernio. Swap its endpoints for the OmniSocials API or an SDK, or point your agent at the MCP server, then recreate your scheduled posts.

3. 3

   Disconnect Zernio when you are live

   Keep both running until your posts and webhooks flow through OmniSocials, then disconnect your Zernio accounts so the per-account billing stops.
