BlitzBrowser is a docker image running browsers. It has multiple features to make it easier to run browsers in production. The cloud version is a managed version of the open source project. Since I'm a solo dev, creating it in my free time, I prefer to focus on the open source version only. The open source version has all the features to be run in the cloud.

To replace the cloud version, you can run Blitzbrowser with Scaleway serverless containers and Cloudflare S3 for free or any other cloud providers offering free tier for docker containers and S3 storage.
