vastlint Closes the Ad Validation Gap with VMAP and DAAST Support

VMAP and DAAST have long suffered from a tooling gap compared to VAST, despite being equally prone to production failures. vastlint's unified validation approach—handling all three formats through the same CLI, library, and MCP interface—significantly streamlines ad tag validation for the ad tech industry. Developers can now catch errors across the entire video and audio ad stack before deployment.
