Verdict
Developer-oriented scheduling and publishing API with a calendar, queues, MCP and per-connected-account pricing.
API-first infrastructure for builders, with social, messaging and blog surfaces; do not equate all supported surfaces to social feeds. Previously called Late. The official rebrand says the product and infrastructure are unchanged.
Additional publishing destinations
The vendor also documents publishing to Slack, iMessage. These destinations sit outside the directory's current platform filters.

- X API usage billed separately
- Previously called Late. The official rebrand says the product and infrastructure are unchanged.
- The first two accounts are free. The current example charges $48/month for ten accounts. X API usage is charged separately.
- Usage-based per account; pricing example: 10 accounts = 2 free + 8 × $6 = $48/month. Graduated rates beyond 10 not verified. X API usage passed through separately.
- The checked vendor pages show a dollar symbol without an explicit currency code. Paid comparison amounts remain unverified.
- The scheduler also supports messaging destinations. Discord, WhatsApp and Telegram are messaging channels, rather than public social feeds.
