 "summary": "Social media scheduler that publishes one post to Instagram, TikTok, YouTube, Facebook, LinkedIn, Pinterest, X and Bluesky, with a queue, calendar, recurring posts and clear failure and reconnect warnings; flat plans without per-channel fees.",
 "best_for": "creators, small businesses and small agencies in Europe that post the same content to Instagram, TikTok, YouTube, LinkedIn and other networks and want one flat price without per-channel fees, with clear warnings when a post fails or a login expires",
 "skip_if": "you want to try a scheduler on your own accounts before paying, you need a refund route if it does not fit, or you need deep analytics and social listening rather than publishing",
 "honest_knock": "There is no free plan and no trial, and the terms make payments non-refundable: the EU 14-day withdrawal right lapses as soon as you use the service. The only way to look before paying is a demo with sample data, not your own accounts. Solo stops at 10 social accounts and 2 team members. Features vary per network with each API, and the FAQ itself says Instagram insights and first comments arrived recently, so this is a young product without a public track record we could weigh. The Lemon Squeezy affiliate listing still describes a 7-day trial that the vendor's own pages do not offer. We have not used PostOnce ourselves.",

  "notes": "(read 2026-10-12 in a live browser on postonce.app and postonce.app/pricing, monthly and yearly views, and in the terms at postonce.app/terms) Two plans, priced in euros including VAT, with approximate dollar figures shown beside them, and no charge per connected network. Solo is €15 a month, or €144 a year billed once, which works out at €12 a month: 10 social accounts, 2 team members, unlimited scheduled posts, automatic media resizing, recurring posts, a media library with Canva, Google Drive and Dropbox import, a link shortener, hashtag groups and basic post analytics. Pro is €30 a month, or €300 a year (€25 a month): unlimited social accounts, 3 workspaces, 5 team members, import from the platforms, roll-up reporting across workspaces, priority support and API access. Annual billing is two months free, which the page labels as saving 17%. Supported networks per the FAQ: Instagram, TikTok, YouTube, Facebook, LinkedIn, Pinterest, X and Bluesky, with the note that individual features vary with each network's API. There is no free plan and no trial: the page says billing starts when you subscribe, and an interactive demo with sample data stands in for a trial. The terms say plans renew automatically, can be cancelled at any time to the end of the paid period, carry no pro-rated refunds, and are otherwise non-refundable; EU consumers have a 14-day right of withdrawal that they give up once they start using the service.",

PostOnce, read on 12 October 2026, is €12 a month billed yearly (€144 a year, VAT included) for 10 social accounts, 2 team members and unlimited scheduled posts, with no trial. On allowance PostOnce gives more for less; Later has the longer record and lets you try it on your own accounts first. The currencies are not converted here."
