Most comparison pages are written by the winner. I wrote this one, and it lists the things my competitors do better than Rubinyun: you are going to find out anyway, and finding out later is worse for both of us.
The one-line version. Rubinyun charges per published post, not per connected channel. A channel is one Instagram profile: ten channels cost the same as one, and a token is spent only when a post actually goes out. And among the API-first schedulers built for automations, it is the only one that computes the best posting time by analysing the profile's own history, not generic averages.
But it publishes to Instagram only, it has no visual calendar and no team features. If you post to five networks, or work with a team, one of the tools below will serve you better, and the rest of this page says which.
The clearest difference is not a feature, it is the meter. Almost everyone else charges you per connected channel: the bill grows with the number of accounts you manage, whether those accounts publish twice a week or never. Rubinyun charges you per published post, and connecting a channel is free: one account, as many channels as you like, one for each Instagram profile, all drawing on one shared balance.
Take ten Instagram profiles, four posts each per month, so 40 posts, and look at what each tool is counting:
| Ten channels, 40 posts a month | What the meter counts |
|---|---|
| Rubinyun | Published posts. Channels are free and unlimited, and a token leaves your balance only when a post actually goes out. |
| Buffer (Essentials) | Connected channels, billed per channel per month. |
| Publer (Business, the plan with the API) | Connected accounts, billed per account per month. |
| Post Bridge | Connected accounts, and the API is a paid add-on on top of the plan. Their Starter tier caps at 5 accounts, so ten channels need a higher one. |
| Later (Starter) | Profiles, sold in sets. And there is no public publishing API, so an n8n workflow cannot post to it at all. |
And a token is spent only when the post actually goes out. If Instagram rejects it, you are not charged for the attempt: you pay for a published post, not for the right to try.
This is the case where the gap is widest, and it is worth saying who it fits: an agency or a freelancer with many client profiles that each post a few times a month. Invert the numbers and the advice inverts too: if you publish 200 times a month, do not buy tokens: take the €19/month unlimited plan (still one price, still any number of channels), or a flat plan elsewhere. Tokens are for irregular volume, not for a firehose.
Read on each vendor's own pages on 14 July 2026. We deliberately do not quote their prices here: price lists change, and a figure left behind on this page would become a lie nobody would notice. What a meter counts, and whether a tool has a publishing API at all, do not change with a price list. For what Rubinyun costs, see our pricing. Where a vendor's page was unclear or unreachable, I say so rather than guess.
| API access | Free tier | The meter counts… | Platforms | Best time from your data | |
|---|---|---|---|---|---|
| Rubinyun | Included on every plan, free tier included. No subscription needed. | Yes: 10 posts/month, API included | Published posts. Profiles free and unlimited | Instagram only | Yes, by weekday and hour |
| Upload-Post | On paid plans, and on their free tier too. | Yes: 10 uploads/month, API included | Subscription, capped by profiles (5 on Basic) | 13, incl. TikTok, YouTube, LinkedIn, X | Not documented |
| Post Bridge | A paid add-on on top of a plan (verified in their help centre). | No (trial only) | Subscription, capped by accounts (5 / 15 / unlimited) | ~9, incl. TikTok, LinkedIn, X | Not documented |
| Buffer | On every plan, free included (1 key, 3,000 requests/month). | Yes: 3 channels, 10 queued posts each | Connected channels | ~10 | Partly: personalised only in Analytics, on paid plans, Instagram Professional, and only above 100 followers |
| Later | No public publishing API documented (the only public API is for reporting). | No (14-day trial) | Subscription, profiles in sets | Instagram, TikTok, Facebook and more | Yes, and it is one of their strengths |
| Publer | Business plan only. | Yes, but no API on it | Connected accounts | Many | Yes, on Business |

Not a rhetorical exercise. These are the reasons to pick someone else.
Two things, and I am not going to inflate them into ten.
Rubinyun computes the best posting time by analysing the profile's own history, not generic averages. It reads the engagement of your recent posts through the Instagram Graph API and works out the best hour for each weekday of your audience. Not "6pm is good for fashion accounts in the US".
Be precise about who else does this: Later does it well, Publer does it on its Business plan, Buffer does it only inside Analytics, on paid plans, on Instagram Professional accounts with 100+ followers, while the times it suggests in the scheduler itself are industry averages. But among the two schedulers built like Rubinyun, for automations, API-first (Upload-Post and Post Bridge), neither documents any best-time feature at all. That is the honest shape of the claim: Rubinyun is not the only one that does it; it is the only one that does it with an API you pay by the post.
€5 buys 25 posts and they never expire. If you publish four times this month and nothing in August, you pay for four posts. Everyone else in the table sells you a month, and several sell you a month per connected channel, so their bill grows with the number of accounts whether they post or not. Here ten channels that post occasionally cost the same as one that posts often, or nothing at all beyond the tokens you use.
And a token is charged only when the post actually publishes: if Instagram rejects it, you are not charged for the attempt. You pay for a result, not for the right to try.
So, choose Rubinyun if: you automate with n8n, Make or your own code; you publish to Instagram; you want the hour picked from real data instead of a hunch; and you would rather pay €5 for 25 posts than a subscription per profile, every month, forever.
Choose someone else if: you need several networks today, a visual calendar, a team, or deep analytics. That is a better outcome for you, and I would rather you came back in six months than left disappointed now.
I did, and I am the one who built Rubinyun. Not after studying this market: after months of being at the keyboard at six in the evening to press "publish" myself, because Instagram's API has no way to accept "put this out on Friday at six". The advice I got was to subscribe to one of the tools in the table above. Instead I used the Linux domain I already had: two days and it was publishing my carousels on its own, three more to turn it into something someone else could use. The accounts, the payments and this page all came after that.
Which is also why I know exactly where it falls short, and you have just read the list: one network, no calendar, no team. And connecting Instagram still means pasting a Meta token by hand, a real limitation, not a modest-sounding one.
That is also why this page is written the way it is. I could have listed six columns of green ticks; you would have discovered the missing platforms on day two and never come back. The numbers above come from the vendors' own pages, read on 14 July 2026, and where a page was unclear or unreachable I said so instead of filling the gap with a guess. If you find a figure that is wrong or has changed, tell me and I will correct it.
