Frequently Asked Questions

Is there really no paid tier?

Correct. This is a community project by the creator of itty.dev. It's free thanks to the generous support of my GitHub Sponsors.

What's the catch?

There isn't one. I don't sell your data. I hate ads. I don't upsell. I built this to reduce the friction of adding realtime functionality to my own projects.

Will it stay free?

Yes. I love building. I don't love running a business or taking payments. Thanks to the long-standing support of my incredible GitHub Sponsors, I can stay focused on building, rather than selling.

Are there rate limits?

There are basic anti-abuse protections (connection rate limiting, message rate limiting) to keep the service healthy for everyone. Normal usage will never hit them.

What about SLAs?

This is a free service. I aim for high availability but don't offer formal guarantees. The infrastructure is simple and resilient, and downtime is rare.

Can I self-host?

Eventually, yes! I'm working on a self-hosted version of the service. However, the client is designed to improve the experience of any WebSocket connection - so you can use that on your own servers today.
