# Parabola vs. Retool

> Parabola vs. Retool: Retool builds internal UIs on clean data, with engineering. Parabola does the data work and produces the interface from the same Flow.

## TL;DR

Retool builds the interface. Parabola builds the data work and the interface together.

- **What Retool assumes:** That the data behind the tool is already clean, and that something else is producing it. Retool is the front end.
- **Who builds it:** Retool expects an engineer with SQL and JavaScript. In Prowork you describe the process and each step is generated for your logic.
- **Where Retool genuinely wins:** Genuinely custom app behaviour — write-back forms, complex state, bespoke component logic.
- **Bottom line:** Pick Retool when you need a bespoke internal application. Pick [Parabola](/) when the hard part is the data behind it.

## What each one is for

Retool is an internal tools builder. You connect data sources, write queries, drag components onto a canvas, and use JavaScript to wire behaviour between them. It is a strong product for teams with engineering capacity who need an internal application that behaves exactly a certain way.

Parabola starts one step earlier. The reason most internal tools are hard is not the buttons — it is that the data behind them arrives across several systems in inconsistent shapes and needs joining, cleaning, and reconciling before anything can be displayed. Parabola does that work, and Artifacts turn the result into an interactive app.

## Parabola vs. Retool at a glance

| Dimension | Parabola | Retool |
| --- | --- | --- |
| Where it starts | At the data: joining, cleaning, and applying business rules across sources | At the interface, on data you already have in usable shape |
| Who builds it | The ops or finance person, by describing the process | An engineer, with SQL for queries and JavaScript for behaviour |
| Pipeline behind the tool | Part of the same Flow | Built separately, in something else |
| Interface | Artifacts generated from the Flow's data and styled to your brand | Fully custom, component by component |
| Custom app behaviour | Presentational and workflow-shaped: dashboards, pivots, exception queues, recommended actions | Genuinely bespoke — write-back forms, complex state, custom component logic |

## The pipeline is usually the actual problem

It is easy to underestimate how much work sits behind an internal tool. Before a queue of exceptions can be displayed, something has to pull rows from the ERP, match them against a partner file, normalise the vendor names, work out which rows disagree and why, and keep doing that every morning. Retool does not do that part — it assumes it is done.

In Parabola that work is the product, and the interface comes out of it. The person who understands the process describes it, Prowork generates the steps, and the Artifact at the end is fed by the same governed pipeline, with every step showing its input, logic, and output.

## When Retool is the better choice

If you need an application rather than a view — write-back forms with real validation, complex interaction state, components behaving in bespoke ways — Retool is built for that and Parabola is not. If you have engineering capacity and the data is already clean, Retool will get you further.

## Which one is right for your team

Choose Retool for bespoke internal applications built by engineers on data that is already in good shape.

Choose [Parabola](/) when the data work is the hard part, and the team that owns the process should be able to build both the pipeline and the view without waiting on engineering.
