changelog.com
In short: Changelog Media (changelog.com) accepts developer media sponsorship. It is paid to submit, takes a moderate amount of preparation, and scores 56/100 on our impact ranking (long tail).
Run a clearly disclosed campaign for your tool’s developer and security tools across relevant Changelog podcasts or newsletters.
Free news submissions explicitly reject commercial products and services, so use sponsorship; treat links as ads, not PageRank.
Priority is medium, which sets the band. It is paid and moderate to complete, which adjusts it within that band. The score ranks your queue — it is not a measure of domain authority.
