Upload-Post is a broad, budget-friendly publishing API — 22 platforms, a genuinely free tier, and a large open-source MCP server — but with fewer official SDKs and mostly annual billing on its paid tiers. Ayrshare covers fewer platforms but adds a mature comments/DMs/mentions engagement layer and monthly billing. Neither is us — this is a factual, sourced comparison of the two of them, so you can judge which fits your build.
Every figure below is sourced from upload-post.com and ayrshare.com as of this writing and may change — verify current details on their sites before deciding.
| Dimension | Upload-Post | Ayrshare |
|---|---|---|
| Pricing & free tier | A free plan at $0/mo (10 uploads/mo, no card required). Paid plans list a Professional tier at $33/mo ($400 billed annually) and a Business tier at $350/mo ($4,205 billed annually) — both priced as annual commitments on the pricing page. | No permanently free plan — a 28-day free trial, billed monthly. Paid plans list from $149/mo (Premium, 1 social profile) up to $599/mo (Business, 30 profiles), with custom Enterprise pricing above that. |
| Platform coverage | Covers 22 platforms, including mainstream networks (TikTok, Instagram, YouTube, Facebook, LinkedIn, X, Threads, Pinterest, Bluesky, Reddit, Google Business) plus niche and publishing targets (Discord, Telegram, Slack, Mastodon, Nostr, Lemmy, Dev.to, Hashnode, WordPress, Whop, Listmonk). | Publishes to 14+ platforms: Facebook, X, Bluesky, Instagram, LinkedIn, Reddit, Telegram, TikTok, Google Business Profile, Threads, Pinterest, Snapchat, YouTube, and WhatsApp (beta). |
| SDKs | Official SDKs for Python and JavaScript/Node.js. Other languages integrate directly against the REST API rather than through an official generated client. | Official SDKs for Node, Python, Go, and a CLI. |
| White-label / embeddable connect flow | A white-label "Connect API" using profile-scoped JWT tokens so you can embed the OAuth flow in your own UI without exposing API keys to the browser — a token-scoping model rather than a verified custom domain with brand configuration. | A branded OAuth linking page with your logo and domain starting on the Launch plan ($299/mo); full custom CSS, favicon, and footer are gated behind the separate Max Pack add-on. |
| Webhooks & delivery detail | Lists webhooks as part of its feature set in marketing copy, but public documentation doesn't detail payload signing, event types, or a per-target delivery model. | Real-time webhooks for posts, comments, mentions, and DMs, with a dashboard to replay events and audit requests. |
| Engagement API (comments, DMs, mentions) | Public documentation centers on publishing, scheduling, and account management; it doesn't describe a comments/DMs/mentions inbox the way Ayrshare does. | Comments, mentions, and DMs are handled as API objects with dedicated webhooks and a dashboard for review. |
| MCP / AI-agent support | An open-source MCP server (published on GitHub) exposing roughly 50 tools for publishing, scheduling, analytics, and account management to any MCP-compatible agent. | A native MCP server exposing roughly 27 tools covering publishing, analytics, history, comments, DMs, and profiles. |
You want the broadest platform list (22, including blogging targets like Dev.to, Hashnode, and WordPress, plus Discord, Slack, and Mastodon), a genuinely free permanent tier to prototype on, and a JWT-scoped embeddable connect flow. You're fine with mostly-annual billing on paid tiers and only two official SDK languages.
You need mature comments/DMs/mentions handling with dashboard replay and audit, prefer monthly billing without an annual commitment, and want SDKs in more mainstream backend languages beyond Python and Node — Go and a CLI included.
If you want more SDK languages than either option and clearer delivery guarantees than Upload-Post's underdocumented webhooks, PostGate takes a third approach: a free sandbox plan with no card required, paid plans starting at $4.00/mo, generated clients in six languages, signed webhooks with documented HMAC signing and per-target delivery evidence, and white-label environments with a verified custom domain.
