Our verdict on OpenAdSource
OpenAdSource is an open-source video ad server for operators serving ads through VAST-compatible players. Its clearest fit is developers prototyping self-hosted video ad serving, especially solo operators or small teams who want campaign controls and tracking in their own environment. It serves VAST 4.2 inline responses and provides campaign and ad management through a Next.js dashboard. The scope is focused on video, rather than a general-purpose ad server covering multiple ad formats.
The feature set covers a practical serving loop: campaign budgets and frequency caps are managed atomically using Redis, with GeoIP country and device-class targeting. Signed tracking pixels include event idempotency, and reporting includes campaign performance funnel and daily-bar views. Prometheus metrics cover both the ad server and worker. Creatives can be uploaded through presigned URLs to MinIO, with S3-compatible storage also listed. Player integrations include video.js, JW Player, Google IMA, and hls.js, making it relevant where those players are already part of a web video stack.
OpenAdSource is deployed with Docker Compose and uses Go services, Postgres, Redis, and an S3-compatible store; the repository describes a single-VM setup and provides self-hosting and integration documentation. That makes deployment a meaningful responsibility for adopters, rather than a managed service experience. The software is available as open source without a paid product plan, and support is through documentation and community. Choose it when self-hosting and a narrow VAST video workflow are priorities; teams seeking broad ad-format coverage, a managed platform, or commercial support should consider alternatives.
