PostOnce review
Automation-focused crossposting for teams managing multiple social accounts.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
PostOnce is a social publishing and crossposting tool for creators, teams, small businesses, social media managers, and agencies. It connects accounts across Instagram, YouTube, Facebook, X/Twitter, LinkedIn, Threads, Bluesky, TikTok, and Pinterest. Users can create automated crossposting workflows, publish directly, schedule posts, reuse existing content, and repurpose images. Web and API access, OAuth account connections, approval workflows, REST API access, and MCP integrations support both standard publishing and automation-led operating models.
Pricing is organized by the number of social accounts managed. The Creator plan costs $29 per month or $290 per year and supports 15 social accounts, unlimited workflows, unlimited posts, scheduling, existing-content reuse, and image repurposing. Pro costs $69 per month or $690 per year for 50 social accounts with the same listed features. Agency costs $199 per month or $1,990 per year for 200 social accounts, again with unlimited workflows and posts. The annual amounts reflect two months free, while access begins with a 7-day trial rather than a perpetual free plan.
Its strongest fit is for teams that value repeatable crossposting and content reuse over a broad social inbox or deep reporting suite. Integrations include Google Drive, Canva, ChatGPT, Claude, Claude Code, Codex, Cursor, Grok, NanoClaw, OpenClaw, Hermes Agent, n8n, Zapier, Make, and MCP clients. That ecosystem, combined with API access, gives automation-focused teams multiple ways to connect content creation and publishing. PostOnce is less suitable for buyers prioritizing a verified inbox, analytics, or detailed publishing depth. Choose it when account scaling and workflow automation are central; consider an alternative when community management and reporting are the primary requirements.

- Unlimited posts and workflows on every listed plan
