Low-code Platforms Converging to MVC
Retool: the $82M ARR internal app builder
The important shift is that low code is turning from a point tool into a full stack, because once a platform owns the data layer, the logic layer, and the UI layer, it can keep users from stitching together three separate products. Retool started from the engineer side with apps on top of production databases, then added workflows and a database. Airtable started from the database, then added automations and interfaces. Zapier started from automation, then added tables and interfaces.

Retool’s home turf is the production database. Most usage starts with an engineer needing an internal admin panel or ops tool that reads and writes live company data, like refund tools, compliance consoles, or loan approval dashboards. That makes its UI, logic, and permissions converge around operational work, not lightweight team collaboration.

Airtable and Zapier approached the same stack from the opposite side. Airtable began as a spreadsheet database for marketers and ops teams, then layered on automations and interfaces so non creators could use cleaner front ends. Zapier began as trigger action plumbing, then moved toward storing data and presenting interfaces so workflows did not need Airtable plus another front end.

This convergence also changes competition. Retool’s biggest alternative was often building in React, while Airtable and Zapier grew by replacing messy spreadsheet plus automation stacks. As each adds the missing MVC pieces, buying one platform becomes easier than paying for several disconnected tools and keeping them in sync.
The next phase is a fight over who becomes the default app layer for work. Retool is best placed where companies need secure tools on top of live systems of record. Airtable and Zapier are strongest where business teams want to assemble software without engineering. The winners will be the platforms that make the full stack feel native enough that users stop thinking in separate layers at all.
