The problem

A full-service marketing agency needs a UTM builder, an attribution engine, a GTM generator, a schema.org generator, a redirect manager, and SERP tracking on day one. Buying each from a SaaS vendor is ~$400 per month per agency and lands the data in six different silos. We wanted one self-hosted stack with the agency's data in one database.

How we built it

1. 01FastAPI backend with 77 endpoints and a PostgreSQL data model tuned for agency multi-tenancy.
2. 02Next.js frontend with shadcn/ui for the agency-operator UX — UTM builder, attribution dashboard, schema generator, redirect manager, internal linker.
3. 03DataForSEO integration for real SERP intelligence when needed; MOCK_MODE for development without burning credits.
4. 04Docker Compose stack with Caddy terminating HTTPS, a single docker-compose up from a fresh box.

Outcome

MVP through seven phases. Replaces ~$3,500/month of commercial SaaS on paper; unavoidable cost shrinks to ~$80–170/month (LLM + voice + DataForSEO + VPS). Runs in mock mode today with zero external keys.
