PostFast is the closest neighbour Preflight has: a flat-priced scheduler where the REST API and the MCP server come with every plan, aimed at creators, small brands and agencies. The differences are in the unit you pay for, the networks, and what happens to a post before it goes out. This page puts the two side by side from their live pricing pages. For other tools in the range see the best free social media schedulers.

Where PostFast is ahead
- X and Google Business Profile. Both are named on its pricing page; Preflight posts to neither.
- Team size at the low end. Creator gives five users and four workspaces for €29, where Preflight's Starter has one seat and Pro three.
- Bigger queues. 3,000 queued posts at €29 and unlimited from €99.
- Workspace branding for agencies on Pro and above, and a priority support tier.
- Native apps. It links iOS and Android apps in its footer.
Where Preflight is ahead
- A free plan. Three channels with the API and the MCP server, against a 7-day trial.
- Mastodon, Telegram, Discord and Tumblr. PostFast covers Telegram of those four; see the Discord page for what posting to a server involves.
- Checks first. An Instagram caption with 31 hashtags, a PNG for Instagram, a TikTok clip at 120 fps or a Threads post over 500 characters is stopped in the composer with the reason, using the rules on the limits page.
- Price at small sizes. Eight channels for $13 against four accounts for €12; twenty channels for $24 against twelve accounts for €29. The prices are on the pricing page.
- Unlimited workspaces on every paid plan, because channels are the shared limit.
What they share
Flat pricing, a calendar, drafts, analytics, a comment inbox, an API and an MCP server on every plan, Zapier and n8n, and the networks Instagram, Facebook, TikTok, LinkedIn, YouTube, Threads, Pinterest, Bluesky and Telegram.
Who should choose which

Choose Preflight if you want a free plan, twelve networks including Mastodon, Discord and Tumblr, rules checked before every post, or the lowest price at eight to twenty channels. The API is described in the documentation.
