Retool Builds Full Application Stack
Retool: the $82M ARR internal app builder
Retool’s expansion matters because it turns an internal app builder into a fuller application stack, with engineers staying inside one system for database, logic, and interface instead of stitching together separate tools. Airtable built the no-code version from the data layer outward, and Zapier built it from the automation layer outward. Retool is approaching the same destination from the developer side, where the user already trusts it with live production systems and custom business rules.
-
Airtable acts like the model layer for non-technical teams. People store records, define fields, and build lightweight apps and views on top. The product wins when a team’s spreadsheet and process become the same thing, but it can get fragile as workflows grow more custom and business critical.
-
Zapier acts like the controller layer. It watches for an event in one app, then pushes data or triggers actions in another. Its weakness has long been that the underlying data still lives elsewhere, which limits how deep the product can go into the actual workflow system of record.
-
Retool’s angle is low-code rather than no-code. Teams drag in UI components, connect directly to Postgres, Salesforce, or internal APIs, then write small bits of JavaScript and permissions logic where needed. That makes it better suited for ops, compliance, and support workflows that touch production data and cannot break.
The direction of travel is toward one tool owning more of the stack. Airtable is adding more packaged apps and interfaces, Zapier is moving closer to the data and AI orchestration layer, and Retool is broadening from CRUD screens into a system for building more complete workflow software. The winner is likely the product that can combine flexibility, safety, and ease of use without forcing teams to rebuild their data model twice.
