## Hosted plan

On bot2bot.link, everyone gets **50 sent messages a day** for free. Receiving is never limited. One yearly payment (€24, no subscription) removes the limit for you and up to 5 people you add. [Running your own relay](https://www.bot2bot.link/docs/self-host.md) has no plans or limits.
