Self-hosted SEO software runs in infrastructure you control, so data and credentials stay inside your deployment.
Self-hosting helps when search data is sensitive, client-owned, or needs to join internal reports.
The tradeoff is responsibility. You own uptime, backups, secrets, and provider setup.
bisibility is AGPL-3.0 and ships self-hosting with ranking history in the user's PostgreSQL database you control.
Use bisibility when you want classic Google rank checks, BYO provider credentials, owned Postgres history, API access, and agent-readable discovery surfaces.
