OneUp alternative: a free plan, and 10 businesses for $29 a month
OneUp is a social media scheduler sold by social accounts, with a 7-day free trial and no free plan; every plan includes its API and MCP access. PostWire writes a different post for each network from one idea and publishes them — from the dashboard, the REST API, n8n or an AI agent — with pricing per business and a free plan with no time limit.
Short answer. PostWire's free plan publishes to 2 networks per post with the REST API and the MCP server in it, with no time limit; OneUp has a 7-day trial and its plans start at $25 a month month to month ($15 billed annually) for 5 social accounts. 10 businesses on 5 networks are $29 a month on PostWire against $180 on OneUp Growth with 20 extra accounts.
Every OneUp price and feature here was read on OneUp's own pages on Oct 19, 2026, with the link next to it. If they changed since, their page wins.

Where PostWire is better than OneUp
- A free plan that stays free. 1 business, 10 posts a month, 2 networks per post, with the REST API and the MCP server, no card and no time limit. OneUp's plans are paid, with a 7-day free trial.
- Paid plans from $9 a month. PostWire Starter covers 3 businesses and 1,000 posts a month. OneUp Basic is $25 a month month to month ($15 billed annually) for 5 social accounts and 300 scheduled posts.
- Per business, not per account. 10 businesses on 5 networks are $29 a month on PostWire Pro. That is 50 social accounts: on OneUp, Growth's 30 plus 20 extra at $3 each, $180 a month month to month.
- A team from $9 a month. PostWire Starter has 3 seats and Pro 25. OneUp Basic has no additional team members; Intermediate ($60) adds 2.
- Each network's post written for you from one idea: one request returns the TikTok hook, the YouTube title, the LinkedIn post and the Discord message, each in its own shape, ready to publish.
- Mastodon and Telegram published directly, next to TikTok, Instagram, YouTube, LinkedIn, Facebook Pages, Bluesky, Discord and X. OneUp's channel list does not include those two.
- An n8n node next to the REST API and the MCP server, on the free plan too.
Who PostWire is for
- You want a free plan to build on with the API, n8n or an AI agent, with no trial clock.
- You post for several businesses: 10 businesses × 5 networks is $29 here, against $180 a month on OneUp Growth with 20 extra accounts.
- You want each network's post written for you from one idea, and published to Mastodon or Telegram too.
10 businesses on 5 networks each: the monthly bill
An agency or a freelancer with ten clients, each on five networks, about 20 posts per client a month. That is 50 connected accounts, which is where the pricing unit decides the bill.
| Tool | How it's counted | Per month |
|---|---|---|
| PostWire Pro | 10 businesses fit in Pro (10 businesses, unlimited posts, fair use 10,000 a month; 10 × 20 posts × 5 networks = 1,000) | $29 |
| OneUp Growth + 20 accounts | 10 businesses × 5 networks = 50 social accounts: Growth includes 30 and each extra account is $3 a month, so it is $120 + $60 = $180 a month month to month (Intermediate with 35 extra accounts would be $200, Business $300) | $180 |
Monthly billing in USD, before tax. Month-to-month prices as OneUp's pricing page showed them on Oct 19, 2026; Growth is $84 a month billed annually ($1,008 a year). Source: www.oneupapp.io/price, read on Oct 19, 2026; PostWire's prices come from the code that bills you.
What “a different post per network” means
PostWire writes each network's version from one idea in one request — a hook for TikTok, a searchable title and tags for YouTube, a longer first-person post for LinkedIn, a short community message for Discord — and then publishes them. The same request works from the dashboard, the REST API, the n8n node or an AI agent.
The idea: Our invoicing app just shipped dark mode. 412 users asked for it, and it took us 3 weeks because we redid every chart.
Dark Mode is Live 🌑 | Why It Took 3 Weeks to Ship
Dark mode is finally live in our invoicing app — and 412 users asked for it before we built a single pixel. #darkmode What looks like a simple color switch was actually a full 3-week rebuild. Every chart, every data visualization, every graph had to be redesigned from the ground up to work in a dark environment. We weren't going to ship something that half-worked. In this video, we walk you through: — Why dark mode in a data-heavy app is way harder than it sounds — How we prioritized this based on real user requests — The chart redesign process, color contrast decisions, and accessibility checks — What we'd do differently next time If you're building a SaaS product or thinking about shipping dark mode yourself, this one's for you. The stuff users never see is usually the hardest work. #buildinpublic #saasdesign Timestamps: 0:00 — Why 412 people finally convinced us 1:30 — The chart problem nobody warned us about 4:00 — Our redesign process 7:20 — The final result
412 users asked for dark mode. We shipped it last week. Here's the part that surprised us: It took 3 weeks — not because dark mode is hard, but because we have charts. Every chart in our invoicing app had to be rebuilt from scratch. Colors that look clean on a white background? They're invisible or eye-straining on dark. Contrast ratios that pass accessibility standards in light mode? Fail completely in dark. So we didn't just flip a CSS variable and call it done. We redesigned every data visualization. Every axis label. Every tooltip. Every legend. Three weeks of work that most users will never consciously notice — and that's exactly the point. We track feature requests in a dead-simple spreadsheet. When dark mode crossed 400 votes, it jumped straight to the top of the queue. No roadmap committee. No prioritization framework. Just 412 real people saying the same thing. The lesson we keep relearning: Listening to users is easy to say and easy to fake. Actually doing it means sometimes rebuilding things you thought were finished. We think that's the job. If you're building a product right now — how do you decide when a feature request has earned its spot on the roadmap? #BuildInPublic #SaaS #ProductDevelopment
