FireGEO, Our Open-Source SaaS Starter for Building GEO Apps

The playbook is being rewritten right now. For twenty years, we mastered Search Engine Optimization (SEO). Now, a new paradigm is emerging. Generative Engine Optimization (GEO). It’s the art and science of ensuring your brand is visible, accurately represented, and recommended by AI models like ChatGPT, Claude, and Perplexity.

Everyone is talking about GEO, but the tools to build a business around it are still being forged. The barrier to entry isn’t just figuring out the AI. It’s building the entire SaaS infrastructure around it. User accounts, billing, databases, and a scalable front end.

We believe the best way to accelerate a new field is to give builders the right tools. So, to kickstart the GEO ecosystem, we built a template to do exactly that.

Today, we’re open-sourcing FireGEO. The first SaaS starter kit for building a business in Generative Engine Optimization.

FireGEO isn’t just another monitoring tool. It’s a complete, extensible, and open-source Next.js starter kit. It provides the full foundation you need to launch your own GEO-focused SaaS product, letting you skip the boilerplate and focus on innovation.

It’s built on a simple premise. Give developers a launchpad with 90% of the foundational work already done.

Ready from Day One. User authentication, subscription billing, and a scalable database are pre-configured.

No Vendor Lock-In. It’s open source. You have full access to the code. Swap out any component you want.

Core GEO Functionality Built-In. It comes with a powerful brand monitoring engine that you can use as-is or extend for any niche.

We’ve integrated best-in-class tools to handle the heavy lifting, so you can focus on building your unique GEO product.

The GEO Core Engine is the heart of the starter. A powerful brand visibility monitor. It uses smart scraping with Firecrawl to reliably scrape and structure data from any website to understand brand context. Multi-provider AI analysis queries OpenAI, Anthropic, and Perplexity to analyze brand visibility, sentiment, and ranking. Automated competitor discovery identifies key competitors to provide a rich, comparative analysis.

The SaaS boilerplate is what separates a tool from a business. Authentication with Better Auth provides secure user registration, login, and session management out of the box. Subscription billing with Autumn & Stripe offers a complete, production-ready billing system for managing plans and usage-based credits. Database with PostgreSQL & Drizzle delivers a modern, type-safe database stack that’s ready to scale. Frontend with Next.js & Tailwind CSS creates a beautiful, responsive interface that you can easily customize.

GEO is a nascent field. The strategies and metrics that will define it are still being discovered. We don’t pretend to have all the answers.

Instead, FireGEO is our contribution to the community. A starting point. We built it to be a powerful foundation that anyone can use, understand, and build upon. By open-sourcing it, we’re inviting you to join us in defining the future of this exciting space.
