As answered by people managing GitHub and SchemaGen.
SchemaGen's answer:
Instead of just being a schema generator, schemagen allows you to remotely deploy, manage, monitor and update your schema from one place, it saves time and makes a difference.
SchemaGen's answer:
Because of the 800 Schema.org types, the built in validation, the monitoring and client reports, the ability to dynamically deploy your change, anywhere and anytime.
SchemaGen's answer:
Mainly SEO Agencies and SEO Consultants with 10-20 clients, you don't want to have to dig through their site to pray the changes took place properly, just use the SDK one time and let us handle the rest.
SchemaGen's answer:
A conversation with an SEO specialist! I worked at an agency, and I'm a developer, I didn't really work closely with my SEO department, but they where really cool! So I started picking their brain about what would make their lives easier, and eventually the concept of remote deployment came up, I thought of it like Git for SEO schema.
SchemaGen's answer:
Next.js is the primary framework, PostgreSQL is my database, then we use Firecrawl and Claude for data acquisition, and a tri-layered validation layer with Firecrawl, and finally a dynamically loaded schema library, and context in our database.
SchemaGen's answer:
Friends and Family right now! I just dropped on the 5-6
