Caddi and Mendix solve different problems, and treating them as the same thing is an expensive mistake. Mendix is an enterprise low-code application platform (now Siemens-owned): you build a custom application, then deploy, version, and maintain it. Caddi has no app to build. You record an existing workflow once and Caddi runs it as deterministic code, maintained for you. Caddi suits ops teams in law and finance that want a workflow automated, not a new application to own.
The basics
What is Mendix?
A Siemens-owned enterprise low-code platform where developers visually model and build a custom application, its data model, UI, and logic, then host, version, and maintain it through a full app lifecycle.
What is Caddi?
The deterministic AI automation platform for ops and admin teams. Ops teams teach Caddi their workflows over a screen share, and then Caddi runs them reliably hundreds of times a week.
The fundamental difference
Standing up Mendix means committing to an application project: you scope requirements, model a data structure, build a UI and the logic behind it, deploy it, and then own versioning and maintenance over time. Even as low-code, it is still software you build and run. Caddi does the opposite. There is no app to build. A non-technical teammate records an existing workflow once, Caddi writes it as deterministic code over APIs, and Caddi maintains it for you.
What it takes to stand one up
The two paths look nothing alike day to day. Toggle between them to compare who builds it, how long it takes, and who keeps it running.
- 1Record the workflow on a screen-shareA non-technical teammate walks through the existing task once, across your current tools.
- 2Caddi writes deterministic code over APIsNo app to model or deploy. Caddi automates the work between the systems you already run.
- 3Documents are read nativelyVaried PDFs and shared inboxes are handled out of the box, no extra modules to build.
- 4Caddi maintains itUpkeep and edge cases are handled for you, often with automations live in days.

| How it's built | Developers model data, UI, and logic | Record the task once on a screen-share |
| Deliverable | An app you deploy and host | Deterministic code over APIs |
| Documents & email | Built as part of the app | Native reading of varied PDFs & inboxes |
| Who owns it | A development team | Non-technical ops staff |
| Maintenance | Internal, ongoing app lifecycle | Built & maintained by Caddi |
| Best fit | Bespoke enterprise applications | Law & finance back office |
How they score where it counts
Mendix is a deep, mature platform for building custom enterprise applications with full lifecycle control. Caddi is not an app builder. It is the fastest way to take a repetitive workflow off your team, across whatever systems you already have, and keep it maintained for you.
When Mendix is the right call
Mendix is a strong fit if you genuinely need to build a bespoke, long-lived enterprise application with its own UI that users log into, a customer portal, an internal system of record, or a custom product, and you have a development team and the budget to build, deploy, and maintain it over time.
When Caddi is the right call
Caddi is the better fit if your real goal is to get repetitive back-office work off your team (intake, filing, PDF → system of record, triage, reconciliations), if you want it live in days rather than a quarter, if the people who own the process are non-technical, and if you would rather automate an existing workflow than build and own a new application. SOC 2 compliance and audit trails come built in.
Which fits your situation?
Mendix
Building a bespoke application with screens, a data model, and logic is exactly what Mendix is for.
See Caddi on your back-office workflows
Bring a workflow your team runs today, intake, filing, invoice prep, reconciliations. Caddi will build it from a screen recording and run it across 70+ tools. See real examples or book a demo, or explore Caddi for law and finance.

Frequently asked questions
What is the difference between Caddi and Mendix?
Mendix is an enterprise low-code application platform: you model and build a custom application (its data model, UI, and logic), then deploy, version, and maintain it. Caddi has no app to build. A non-technical teammate records an existing workflow once, Caddi writes it as deterministic code that runs over APIs, and Caddi maintains it for you. Mendix builds and owns an application; Caddi automates an existing workflow across the tools you already run.
Is Caddi a Mendix alternative?
It depends on the goal. If you need a bespoke, long-lived application with its own UI that users log into, Mendix is built for that. If your goal is to take a repetitive back-office workflow off your team's plate, Caddi is usually the faster path, because there is no application to scope, build, deploy, or maintain. You record the workflow and Caddi runs it, frequently live in days.
Does Caddi require developers like Mendix?
No. Even as a low-code platform, Mendix is still a software project: developers model the app, wire the logic, deploy it, and own it over time. With Caddi, a non-technical staff member records the task on a screen-share and Caddi builds the automation, so paralegals, ops admins, and billing coordinators can own automations without writing or maintaining an app.
When should I use Mendix instead of Caddi?
Use Mendix when you genuinely need to build a custom enterprise application: a customer portal, an internal system of record, or a bespoke product with its own UI that users log into, and you have a development team to build and maintain it. Caddi is the better fit for automating back-office workflows across existing tools, not for building a new application.
