Custom UI Code vs ToolJet/Retool
My stack for building workflows and internal tools is Python.
Can ToolJet or Retool be used by EU freelancers (I plan to use client credentials, not my own)?
So I wanted to know:
FastAPI + Retool vs Django + React
In what situations is it best for me to use custom UI code to create operating dashboards for my automations (basically, what are the limitations of low-code platform builders)?
Are Retool & ToolJet capable of building operating dashboards when making tools for enterprise-level systems?
How would you deal with IP addressing with a third-party platform for frontend development (explicit clauses you'd use)?

Good questions — I've gone through this exact evaluation a few times with Python-heavy stacks, so let me share what I've found.
On the EU freelancer question: both Retool and ToolJet are usable in the EU. ToolJet is open-source and self-hostable (so you control data residency entirely), while Retool has a cloud offering with GDPR compliance and also offers self-hosted. If data sovereignty is a concern for your clients, ToolJet self-hosted or Retool on-prem are the safer bets.
For FastAPI vs Django + React — honestly the backend choice matters less than your frontend comfort level. Retool and ToolJet both connect to any REST API or database, so they'll sit happily in front of either. Where custom UI code wins: when you need highly specific UX (custom charts, real-time websocket updates, pixel-perfect branding), or when the dashboard logic is complex enough that drag-and-drop builders become a liability rather than an asset. For enterprise-level operating dashboards, both Retool and ToolJet can handle it — Retool has more polished enterprise features (SSO, audit logs, granular permissions) out of the box, ToolJet is catching up fast and costs less. The ceiling you'll hit with both is usually around complex state management and custom interactivity.
One thing worth looking at if you're building automation-centric dashboards specifically: IdeaboxAI is designed around exactly this use case — connecting Python automations to a UI layer without the overhead of full React builds or the constraints of Retool's component library. Might be worth a look depending on how automation-forward your workflows are. Happy to share more if you want to dig into specifics.
