Your Estimated Cost
At this low volume the API is inexpensive too — but OpenTweet still saves you the developer account, API key setup, AI writing, and scheduling, all for a flat $29/mo on Advanced.
How the options compare
| Option | Cost | No API key | No per-post fee | Notes |
|---|---|---|---|---|
| OpenTweet | $29/mo (Advanced) | Flat price, AI generation, scheduling, threads — no API key. Link posts included on Advanced (10/day) and Agency (20/day). | ||
| X API (pay-per-use) | ~$4.80/mo | Per-post fees scale with volume, especially for link posts. | ||
| X API Basic tier | from ~$200/mo | Fixed monthly minimum plus posting limits. | ||
| Build it yourself | API cost + dev time | You still pay X, plus weeks of engineering and upkeep. |
