Social Media Scheduler

A scheduler built for short-form video: one calendar that publishes natively to TikTok, Instagram Reels and YouTube Shorts weeks ahead, and generates the content that fills it from your website URL. Automations fill the whole calendar in one click.

In one answer

Fastlane is a social media scheduler for short-form video that publishes natively to TikTok, Instagram Reels and YouTube Shorts from one calendar, schedules weeks ahead, fills the calendar in one click with automations, and generates the posts themselves from your website URL in four formats: AI UGC videos, slideshows, hook + demo videos and memes. Unified analytics attribute signups and sales to each post. Used by 50,000+ businesses; free plan, no credit card.

Traditional schedulers were built for a world of text posts and links. Short-form video needs a scheduler that solves supply as well as timing, which is why Fastlane generates and schedules in one place.

How the social media scheduler works

1

Connect your accounts

Link TikTok, Instagram and YouTube. Fastlane publishes natively to each; no reminder notifications.

2

Fill the calendar

Upload your own videos or paste your website URL and generate AI UGC, slideshows, hook + demo videos and memes. Or run an automation and fill weeks in one click.

3

Schedule and cross-post

Pick slots weeks ahead. The same video can go to all three platforms or be staggered.

4

Measure per post

Unified analytics attribute signups and sales to each scheduled post, across platforms, in one view.

What to look for in a social media scheduler in 2026

Native publishing to the video platforms that matter, not just the ones that were easy to integrate. Cross-posting, because one vertical video belongs on TikTok, Reels and Shorts. Attribution that connects a post to a signup, not just an engagement count. And a way to keep the calendar full when there is nothing to post. Fastlane was designed around those four, in that order.

Scheduling for teams, agencies and multi-account brands

Fastlane supports multiple workspaces and unlimited social accounts on the Growth plan and above, a Whitelabel and Partner API for agencies, and a done-for-you agency service. Brands that need extra accounts can add human-warmed TikTok and Instagram accounts at $100 per account per month, warmed for 5 days in their niche by real people on real phones.

Developers and AI agents can schedule and publish through Fastlane's API and MCP integration.
