I randomly met the Mintlify founders at a networking event, decided to try the product, and immediately fell in love with it. The ease of deployment is incredible, everything just works out of the box, and once I started using it, I never looked back.

They sent us a bookbag. We started using them. We chose PostHog because it’s open source, gives full control over analytics, and makes tracking user behavior and dropoff ridiculously easy.

I chose Supabase over other competitors because it’s incredibly straightforward to work with while still being powerful. The UI is clean and intuitive, making it easy to manage databases, storage, and authentication without digging through complex docs. Setting up projects and integrating storage is seamless, and connecting it to AI or LLM models for coding tasks just works out of the box. I also love how easy it is to manage permissions and row-level access—everything feels transparent and simple, which saves me a lot of time and mental overhead compared with other competitors' sometimes opaque rules systems.

We chose Vercel over competitors mainly for the simplicity it offers. Connecting my GitHub repo and deploying is completely seamless, and every pull request automatically gets a live preview link, which makes collaborating with the team so much easier. Their integration with Next.js is unbeatable—features like server-side rendering and incremental static regeneration just work out of the box, saving me a lot of configuration headaches. On top of that, Vercel’s startup support has been a huge bonus, giving early-stage companies like mine credits and benefits that help cover hosting and team seats, which makes scaling and experimenting without worrying about costs much more manageable.
