What is it?

Subatic is a simple video sharing site you run yourself. Uploaded videos go to an S3-compatible bucket, a separate transcoder processes them, and the finished files are served from a public bucket or domain for playback.

The stack includes a Subatic web app backed by PostgreSQL, a Subatic Transcoder service, and optionally MinIO for local object storage. A docker-compose file starts all of these together with health checks and service dependencies. Storage can be AWS S3, MinIO, or Cloudflare R2, and SQS can be connected to trigger processing from bucket notifications.

The app also supports optional visitor analytics through Umami, Plausible, or Google Analytics, each enabled by environment variables. Upload size limits are set in megabytes.

Key features

  • 01Uploads are stored in S3-compatible buckets such as AWS S3, MinIO, or Cloudflare R2.
  • 02A separate transcoder processes uploaded videos for HLS playback.
  • 03Docker Compose deploys the app, transcoder, PostgreSQL, and MinIO together.
  • 04Optional SQS integration triggers processing from S3 bucket notifications.
  • 05Umami, Plausible, and Google Analytics can be enabled through environment variables.

Use cases

  • Hosting a private or community video library on your own server.
  • Reducing streaming costs by serving video directly from object storage and a CDN.
  • Running a small video sharing site that can be deployed with Docker Compose.

Quick start

  1. 1

    Create a .env file from .env.example next to docker-compose.yml

  2. 2

    Add the required environment variables to the .env file

  3. 3

    Start the services with Docker Compose

    docker-compose up -d

Things to know

  • Needs S3-compatible storage, a PostgreSQL database, and a separate transcoding pipeline, so self-hosting takes real setup effort.
  • Detailed documentation is not yet available, and the README says it is coming soon.
  • Licensed under GPL-3.0, a copyleft license that requires derivative works to be open-sourced under the same terms.
