“Free” means different things across this list — some tools offer a genuinely permanent free tier, some only a time-limited trial that becomes paid, and some are free because they’re a single platform’s own native tool rather than a general scheduler. This guide separates the 20 real options into what they actually are, PostRSS first.

This category genuinely splits three ways, and confusing them is the most common mistake when picking a free tool. Permanent free tiers — PostRSS, Buffer, Later, Publer, Metricool, Zoho Social, Planoly, Crowdfire, Zapier, Make, and IFTTT — stay free indefinitely, capped by posts, channels, or tasks rather than time. Native platform tools — Meta Business Suite, Facebook Creator Studio, X’s own scheduling, Pinterest’s native scheduler, Google Business Profile posts, and VK’s native scheduling — are free because the platform itself provides them, but each only covers its own single platform, with no cross-platform or RSS-triggered automation. Trial-only tools — SocialPilot and several others in the broader scheduling market — market a “free” tier that’s actually a time-limited trial requiring payment afterward; always check whether “free” on a pricing page means permanent or a countdown.
PostRSS’s free plan applies the same real-time RSS-to-social automation as its paid tiers, just with a posting cap, rather than a stripped-down feature set or a trial that expires — the free plan is genuinely usable long-term for a lower-volume site, not a bait to force an upgrade.
Among tools offering real automation (not just native single-platform scheduling), PostRSS, Zapier, and Make all have permanent free tiers capable of RSS-triggered posting, each with different caps — PostRSS is purpose-built for this specifically, while Zapier and Make require building the automation yourself.
Yes — these are provided directly by the platform itself with no time limit, but each only covers that one platform, with no RSS automation or cross-platform posting.
Check specifically whether the pricing page says the free tier has a start date or countdown (“free for 14 days”) versus described as an ongoing plan with usage caps instead of a time limit. When in doubt, checking cancellation and billing terms before connecting real accounts avoids surprises.
Genuinely free, ongoing RSS-to-social automation is a smaller list than “free social media tool” search results suggest once native single-platform tools and disguised trials are set aside. PostRSS’s free plan is built around the same real-time RSS automation as its paid tiers, making it a straightforward starting point if RSS-driven auto-posting specifically, not just general scheduling, is the goal.
