Features and specs

What each product offers, as listed by its team.

Code Effects 5 features
Prefems 13 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.
  • Tier lists (prefems)
    Rank anything with 2 to 12 tiers, using images or plain text. You name the tiers yourself.
  • Rank anything with 2 to 12 tiers, using images or plain text. You name the tiers yourself.
    Other people re-rank your tier list (prefem) their own way, so you can see item by item where they agreed with you and where they did not.
  • Global Hopinion
    Every ranking a subject has ever received, added up into one shared community ranking from S down to F.
  • Opinion Explorer
    A permanent page for every subject, showing the community tier distribution with percentages and vote counts. Two subjects can be compared side by side.
  • Controversiality score
    A 0 to 10 score per subject, so you can tell a settled opinion apart from a split one.
  • Pros and cons
    Short notes written by the community on each subject, voted up or down by everyone else.
  • Subject library
    A shared library of things to rank, or add something nobody has ranked before.
  • Nests

Questions & Answers

As answered by people managing Code Effects and Prefems.

Who are some of the biggest customers of your product?

Prefems's answer:

Prefems is a free consumer product, so it has communities rather than customers.

What makes your product unique?

Prefems's answer:

Most tier list tools give you an image to post. Prefems gives you the reaction to it.

You publish a ranking, and other people rank the same items their own way. Their version is called a hopinion, and you can see item by item what they moved and how far.

Those rankings do not disappear after the post. Every item you rank is a subject with its own permanent page, and every ranking that subject has ever received is counted there into one shared community ranking. So the question stops being "what does this one person think" and becomes "what do people actually think", with the vote counts behind it.

Why should a person choose your product over its competitors?

Prefems's answer:

Other tier list makers are drawing tools. You arrange items, export a picture, and post it somewhere else. The conversation happens off the site, and nothing is kept.

On Prefems the ranking is the start. People answer your list with their own version, the disagreement is shown per item, and every ranking feeds a running total for the item itself. You also get a page per subject with the tier distribution, a 0 to 10 controversiality score, community written pros and cons, and a side by side comparison against any other subject.

It also has the parts a drawing tool has no reason to build: communities with their own rules and moderators, follows, comments, drafts and a feed. It works in the browser and as an app on iOS and Android, and it is free.

How would you describe the primary audience of your product?

Prefems's answer:

People who already rank things and argue about it. Gaming, music, film and TV, football, food, anything with a fandom that likes to debate.

Most of them have made a tier list before, posted the image somewhere, and watched the replies scroll away. They are the ones who care that the disagreement gets counted.

The second group is people who want the answer rather than the argument. They use the Opinion Explorer to look up what a community actually settled on for one thing, and how split that community was.

The site is 16+ and everything public is moderated.

What's the story behind your product?

Prefems's answer:

Everyone ranks things. It is one of the oldest ways people talk about what they like, and the tier list made it a format.

The problem was what happened next. You spend an hour on a list, post the image, and get back a pile of comments saying you were wrong. There is no way to see how wrong, which items people actually disagreed on, or what the group as a whole would have said. The opinion is real, and then it is gone.

Prefems was built to keep it. Someone answers your list by ranking the same items themselves, so the disagreement is measured instead of described. Every one of those answers is added to the item's own page, so over time the community builds a ranking for a game or an album that nobody had to write down. The word prefem is short for preferences, because that is all a tier list ever was.
