In simple English
Rival is a private dashboard that automatically watches your competitors for you. It checks their pricing pages, job listings, and feature updates so you do not have to check them by hand. The program saves old copies of their pages and highlights what changed since your last visit. It runs on your own computer or server and uses an external extraction service called Tabstack to read the pages. You will need a database and an API key from Tabstack to make it work.
What it is
Rival is a Next.js (a React framework for building fast web applications with server-side rendering) web application powered by the Tabstack API (a service that pulls clean data and markdown from web pages). It stores competitor data in a PostgreSQL (an open-source relational database) database managed through Prisma (a tool that helps Node.js applications talk to a database safely).
What it is good for
Solo founders and small teams who want to keep an eye on competing products without visiting ten different websites every week.
- Tracks pricing, changelogs, and job boards in one place.
- Includes an MCP server so AI tools like Claude can query your competitor data.
- Provides automatic change summaries and comparison briefs.
- Requires an active Tabstack API account and key.
- Needs a running PostgreSQL database and some command-line setup.
- Depends on external web structure remaining stable.
