Each of these earns its spot for a specific kind of user. Facts come from each vendor's public pricing page, as of June 2026.
2. ContentStudio
Agencies that want AI content tools, client workspaces, and white-labelContentStudio is the closest like-for-like upgrade from SocialPlanner: it keeps the content-discovery angle — AI content finder, RSS feeds, curation workflows — and layers on 10 of 11 major platforms (everything except Mastodon), proper team seats, approval workflows, client workspaces, and white-label options for agencies. Standard lists at $19/month for 5 accounts and 1 user, with add-ons at $5/month per extra account and $10/month per extra user on lower tiers (as of June 2026); Advanced is $49/month and Agency Unlimited $99/month. The watch-outs: Mastodon is absent from ContentStudio’s integrations page, the entry tier’s per-account and per-user add-on math can climb quickly, no money-back guarantee is listed, and its depth — social inbox, automation rules, white-label — comes with a learning curve that users on G2 and Capterra describe as real. If you want content discovery plus a genuine publishing workflow and team features, ContentStudio is the most direct replacement.

3. Publer
Budget-minded users with 1–2 accounts who want a free planPubler fixes every platform gap SocialPlanner leaves open: it covers all 11 major networks — including TikTok, YouTube, Threads, Bluesky, Mastodon, and Google Business — plus Telegram and WordPress. That alone makes it the clearest pick for anyone leaving because SocialPlanner’s network list is too short. Its modular pricing lists at a $5/month base for one account with extras at $4/month each on Professional — typical configured setups are quoted around $12/month (as of June 2026) — and there is a free plan for up to 3 accounts, excluding X. The trade-offs: AI, analytics, and best-time posting are gated to the pricier Business plan; Instagram connects Business accounts only; and the invoice grows with every account and teammate you add. For a tight budget with platform breadth, it earns its place.

4. OneUp
Auto-repeating posts, RSS auto-posting, and Snapchat/Reddit/Discord coverageOneUp earns its spot for two things SocialPlanner handles weakly: a wider platform list and recurring-post automation. It covers all of SocialPlanner’s publishing destinations plus Snapchat, Reddit, WhatsApp, and Discord, and its auto-repeating posts, post categories, and RSS auto-posting are purpose-built for evergreen content. Starter lists at $15/month for 5 social accounts with a 7-day trial (as of June 2026). The caveats matter: Mastodon is not listed on OneUp’s supported platforms, the Starter plan includes zero team seats — the first seat requires Intermediate at a listed $48/month — and Starter caps scheduling at 300 posts. If Reddit or Discord are part of your mix, or if auto-recurring posts are the heart of your strategy, OneUp is a genuine fit.

5. dlvr.it
Bloggers and publishers auto-sharing RSS feeds to socialdlvr.it is the natural comparison for SocialPlanner’s RSS-first audience: a veteran feed-to-social broadcasting engine that covers all 11 major platforms plus blog and chat endpoints like WordPress, Tumblr, Reddit, Slack, and Discord. Where SocialPlanner couples discovery with scheduling, dlvr.it specialises purely in distribution — connect a feed and posts go out automatically, with content recycling and a bulk scheduler on paid plans. Pro lists at $14.99/month for 10 social profiles (as of June 2026). Two structural differences from SocialPlanner are worth knowing: dlvr.it has no free trial — you pay first and can request a refund within 14 days — and X (Twitter) publishing is capped at 500 posts per month per account on every plan. If auto-broadcasting a feed is the entire brief and you also need to reach Slack, Discord, or WordPress, dlvr.it is purpose-built for that job.

6. Buffer
Solo users with 1–3 channels who want a free planBuffer is the established safe choice for anyone leaving SocialPlanner’s thin network list: it covers all 11 major platforms, Bluesky and Mastodon included, and offers the most generous free plan on this list — 3 channels, free forever (as of June 2026). Paid plans bill per channel at $5/month each on Essentials, with unlimited scheduling and an AI assistant on all plans (including the free tier). The honest caveats: approval workflows require the $10-per-channel Team plan, every connected channel adds to the invoice (11 channels list at roughly $55/month on Essentials), no money-back guarantee is listed, and Buffer is a post composer and scheduler rather than a content-aggregation platform — it does not bundle an RSS feed aggregator or content-curation discovery engine like SocialPlanner does.
