Code Effects 5 features

Fillr.app 6 features

No-code rule builder
Provides a visual, English-like rule editor that allows business users without programming skills to create and modify complex business rules and decision logic.
.NET integration
Designed specifically for .NET environments, allowing seamless embedding into C# and VB.NET applications, which is beneficial for teams already invested in the Microsoft technology stack.
Rule compilation to native code
Rules are compiled directly into .NET assemblies rather than interpreted at runtime, which can result in faster execution performance compared to some interpreted rule engines.
Customizable UI components
Offers embeddable rule editor controls that can be styled and integrated into existing applications, giving developers flexibility in how end-users interact with the rule authoring interface.
Reduces developer dependency
By enabling business analysts to author and update rules directly, it can reduce the need for constant developer involvement when business logic changes, potentially speeding up time-to-market for rule changes.

Possible disadvantages

Limited platform scope
Being tightly coupled to the .NET ecosystem limits its usefulness for organizations using other technology stacks like Java, Python, or Node.js, reducing its overall market flexibility.
Learning curve for setup
While the rule editor is designed for business users, the initial setup, integration, and configuration within a .NET application often requires significant developer expertise and time investment.
Niche market presence
Compared to larger, more established business rules engines and decision automation platforms, Code Effects has a smaller user base and community, which can mean less third-party support, tutorials, and shared resources.
Pricing transparency
Detailed pricing information is not always readily available publicly, which can make it harder for prospective customers to quickly assess cost-effectiveness compared to competitors.
Scalability for complex enterprise needs
For very large-scale, multi-platform, or highly complex enterprise decisioning needs, it may lack some of the advanced features, integrations, and scalability options found in more comprehensive decision management suites.

Questions & Answers

As answered by people managing Code Effects and Fillr.app.

What makes your product unique?

Fillr.app's answer:

It leads with control, not random fill. Capture any web form as a reusable preset, set per-field rules (generated, fixed, your own data, or skip), and refill in one click — plus a built-in Datasets module to build, generate, and export test data. A form-filler and test-data manager in one, no code.

Why should a person choose your product over its competitors?

Fillr.app's answer:

Fake Filler only sprays random data; Mockaroo generates data but can't fill forms. Fillr does both — and lets you fill with your own data, with reusable presets, per-field control, and 60+ locales. No scripts.

How would you describe the primary audience of your product?

Fillr.app's answer:

QA engineers and developers who repeatedly test web forms and need realistic, controllable test data. Demo and sales engineers are a natural secondary audience.

Which are the primary technologies used for building your product?

Fillr.app's answer:

Next.js 15, React 19, and TypeScript dashboard; a Manifest V3 Chrome extension built with Vite and supabase for backend
