Scored from public evidence (GitHub, Hacker News, release activity, free access), rebuilt 27 Oct 2026. Method.
Ranked by evidence — GitHub stars, Hacker News mentions, Wikipedia readership, release activity and how much you can use for free. Recomputed nightly. How the score works.
+ The grid preview is the right interface for anything visual-first.
− Weaker outside Instagram, TikTok and Pinterest.
+ Your own instance, your own API keys, no per-channel pricing.
− Self-hosting means you own the OAuth app approvals each network demands.
+ The free plan is genuinely usable, and the AI drafts read like the account's own voice once fed a few posts.
− Analytics and engagement sit behind the paid tiers.
+ Writes the copy and schedules the post from the same place.
− Jack of all trades - the design side is thinner than Canva.
+ Approval workflows and inbox management that a team of ten actually needs.
− The most expensive way to post a tweet if that is all you want.
+ Comes back with artwork, not just text, which is the half most tools skip.
− Templated look - fine for volume, obvious if every post uses it.
+ Being one-network means the suggestions are drawn from posts that performed on that network.
− One network, and LinkedIn's rules on automation change without notice.
+ Pulls a Shopify or WooCommerce catalogue straight into posts.
− Jack of three trades - each piece is beaten by a specialist.
